Legal and source review date: 4 October 2026. General information only. Contract interpretation, remedies, notice requirements, interim relief, arbitration, deadlines and loss depend on the executed transaction documents, chronology, evidence and law current for the matter.
A post-closing dispute rarely turns on one clause read in isolation. The share or asset purchase agreement may contain a completion-accounts formula, locked-box protection, warranties, specific indemnities, disclosure qualifications, notice conditions, liability caps, an escrow mechanism and an arbitration clause. Turkish contract and commercial law then supply mandatory limits, default rules and procedural consequences. A buyer or seller should therefore begin with the signed transaction suite, the closing record and a disciplined chronology, rather than with a general assumption that a price adjustment, warranty claim or indemnity is automatically payable.
This guide concerns disputes between buyer and seller after closing. It does not revisit pre-closing legal due diligence, value the target, determine accounting figures, calculate a personal deadline or predict an award. No executed agreement, disclosure letter, completion accounts, escrow instrument or case-specific evidence was provided for this local package. The analysis explains the legal questions that must be tested and the records needed to test them. Every operative source and every publication statement must be checked again on the day advice, a filing or publication is prepared.
1. Define the post-closing dispute before choosing a remedy
The first task is to identify the obligation said to have failed. A completion-accounts disagreement may concern the agreed accounting hierarchy, consistency with past practice, leakage, debt, cash, working capital or the treatment of a disputed item. A warranty claim asks whether a statement was contractually promised, whether it was qualified by disclosure, when it was tested and what loss followed. A specific indemnity usually allocates a defined risk and may operate differently from ordinary damages. An escrow dispute adds the stakeholder mandate and release conditions. These categories can overlap, but they should not be collapsed into one undifferentiated demand.
Turkish Code of Obligations No. 6098 starts from contractual freedom: parties may determine the content of their agreement within legal limits. That makes the signed SPA, schedules and incorporated documents the primary map. The same freedom does not validate a term that conflicts with mandatory law, morality, public order, personality rights or an impossible subject. If only part of the agreement is void, the statutory starting point preserves the remainder; the whole agreement may fail where it is clear that the parties would not have contracted without the invalid provisions. These rules matter when a party challenges a limitation, penalty, waiver or remedy clause rather than the transaction as a whole.
The dispute map should separate liability, quantum and procedure. Liability asks what the contract required and whether the requirement was breached. Quantum asks how the contract or general law measures the financial consequence. Procedure asks who decides, which notices were required, whether court relief remains available and what evidence can be used. A strong file identifies the actor for every step: buyer, seller, target, guarantor, escrow agent, accountant, expert, board representative and arbitral institution. It also records which entity paid, received, notified, approved or retained each document.
Fraud, mistake or duress requires a separate analysis from breach. A party induced by the counterparty’s fraud is not bound even if the resulting mistake is not fundamental. Fraud by a third person has a different test, including what the counterparty knew or should have known at signing. A party that wishes to avoid the agreement must also address the statutory ratification rule, while damages can remain available in the circumstances stated by law. These are serious allegations that require verified facts; this package makes no allegation against any transaction participant.
2. Read warranties, covenants and conditions as an integrated allocation of risk
A warranty schedule should be read with definitions, knowledge qualifiers, materiality standards, disclosure rules, bring-down wording, survival periods and exclusive-remedy clauses. The question is not merely whether an adverse fact existed. The reviewer must identify the exact statement, the relevant testing date, the person whose knowledge counts, the disclosure standard and the causal route from inaccuracy to recoverable loss. General statements in a data room may not perform the same function as a formally agreed disclosure, but the answer depends on the actual SPA.
Reciprocal performance rules can affect a demand for contractual performance. A party demanding performance must ordinarily have performed or offered its own due performance unless the agreement or transaction allows it to perform later. Where a debtor does not perform at all or properly, damages follow unless the debtor proves the absence of attributable fault. Obligations to act and negative covenants also have distinct statutory routes: substitute performance may be authorised at the debtor’s expense, a breach of a negative covenant may support damages, and a continuing unlawful situation may support removal or authorised remediation.
The general fault standard is broad, although the transaction’s nature can affect the extent of liability. The Code directs courts and tribunals to use tort provisions by analogy in the contractual setting where the statute so provides. Parties drafting and applying warranty or indemnity provisions should therefore avoid assuming that a label alone determines every issue of fault, causation, mitigation or scope. The contract may allocate a risk strictly, condition it on fault, define recoverable loss or create a special remedy, but each conclusion must be grounded in the wording and mandatory rules.
Conditions precedent and subsequent deserve their own timeline. A suspensive condition ordinarily delays effect until an uncertain event occurs. A resolutory condition ordinarily ends effect when the event occurs, without retroactive effect, unless the agreement or the transaction requires a different result. The Code also prevents opportunistic manipulation: a party that obstructs a condition contrary to good faith may have it treated as fulfilled, while a party that procures its occurrence contrary to good faith may have it treated as unfulfilled. In a post-closing case, these rules may matter to deferred payments, earn-outs, regulatory milestones and release conditions, but the actual drafting remains decisive.
3. Default, cure, rescission and damages require an election supported by a chronology
A due obligation does not always place the debtor in default automatically. The usual rule requires notice. A date jointly fixed by the parties, or fixed through a reserved contractual right used with proper notice, can produce default when the date passes without a further notice. A good-faith restitution debtor on an unjust-enrichment basis also requires attention to the statutory notice rule. For transaction teams, the safe practice is to build a chronology showing the due date, contractual notice mechanism, service evidence, cure discussions and any reservation of rights.
A debtor in default may be liable for loss caused by delay unless it proves absence of fault in entering default. In a reciprocal agreement, the creditor may grant an appropriate cure period or ask the court to do so. The Code identifies circumstances in which an additional period is unnecessary. Once the cure period expires without performance, or a no-cure case applies, the creditor must understand the available election: continued performance and delay damages, or an immediate waiver of performance and delay damages followed by a claim for non-performance loss or rescission. The wording and timing of the election should be explicit.
Valid rescission releases both parties from reciprocal performance and allows recovery of what was already performed. Further loss caused by the agreement becoming ineffective may be claimed where the debtor cannot establish the statutory absence of fault. These consequences can be commercially large in an acquisition, so rescission should not be described as a routine substitute for a disputed adjustment. Corporate control may already have transferred, assets may have been integrated and third-party rights may exist. A legal and operational unwind analysis is required before choosing that route.
Impossibility also needs careful attribution. If performance becomes impossible for a reason for which the debtor is not responsible, the obligation is discharged. In a reciprocal agreement, received performance is generally returned and the right to outstanding counter-performance is lost unless law or contract allocates the risk differently. A debtor that fails promptly to notify the creditor or to prevent increased loss may remain responsible for the added loss. These rules should be tested against the actual obligation; financial inconvenience, accounting disagreement and unwillingness to pay are not automatically legal impossibility.
A release may extinguish an SPA debt wholly or partly without repeating the form of the originating transaction. Its scope, parties, reservations and relationship with unknown claims must be read exactly. The fact that the parties signed a completion certificate, settlement note or release does not answer whether a later warranty, fraud or specific-indemnity claim was reserved.
4. Price adjustments, setoff, limitation and penalties must remain distinct
A completion-accounts mechanism is a contractual calculation process. The SPA normally defines the reference accounts, accounting policies, hierarchy, expert role, timetable and dispute notice. Without those documents and the underlying ledger, no reliable amount can be calculated. A locked-box covenant may instead focus on leakage between a reference date and closing. Earn-outs add performance definitions and operational-control questions. The legal reviewer should preserve the difference between a contractual calculation and a damages claim, even if both appear in the same notice.
Setoff is another distinct route. Where reciprocal money or fungible obligations exist and both are due, a party may set off its receivable against its debt. A disputed counter-receivable can still be asserted in setoff. A receivable that later became time-barred may remain available where it was not time-barred when setoff first became possible. Setoff requires notice, and valid notice extinguishes the reciprocal debts up to the smaller amount from the point at which they became capable of setoff. The SPA may contain further restrictions or mechanisms that must also be tested.
The general statutory limitation period for an SPA receivable is ten years unless a different rule applies. That statement is a general source rule, not a personal deadline. The claim type, accrual wording, contractual notice period, forfeiture condition, acknowledgment, arbitration step and procedural history can alter the analysis. Limitation is interrupted by the debtor’s acknowledgment or specified court, arbitration, enforcement or insolvency steps. The Code also provides an additional period in listed cases where an action or defence fails for forum, curable-error or prematurity grounds after limitation or a forfeiture period has expired.
Contractual penalties should not be treated as ordinary damages without reading the election clause. For non-performance or defective performance, the statutory default allows the creditor to choose the principal obligation or the penalty unless the agreement indicates otherwise. A penalty for late or wrong-place performance may be claimed with performance unless it was expressly waived or performance was accepted without reservation. An enforceable penalty may be demanded without proof of loss. Merchant status matters because the Turkish Commercial Code restricts a merchant debtor’s ability, in the statutory cross-referenced cases, to seek reduction merely by arguing that the fee or penalty is excessive.
5. Merchant notices, invoice records and corporate authority can decide the evidential frame
Each merchant must act as a prudent businessperson in activities relating to its trade. That standard affects how a sophisticated buyer or seller preserves records, investigates a suspected breach and responds to notices. It does not mean that every adverse outcome proves negligence. It does mean that post-closing teams should avoid fragmented communications, undocumented concessions and inconsistent financial positions.
Specified default, termination and rescission notices between merchants must use one of the communication methods stated by the Turkish Commercial Code. The SPA may impose additional addresses, attention lines, language requirements or delivery methods. Service evidence should be preserved independently from the notice text. A message sent to the operational deal team may create awareness yet fail a contractual or statutory notice form; the result depends on the applicable rule and facts.
Invoices and confirmation letters create separate commercial presumptions. A recipient that does not object to invoice content within the statutory period is deemed to have accepted that content. A person receiving a confirmation letter for an oral or technology-mediated agreement or statement is likewise deemed to accept its correspondence with the agreement if no timely objection is made. These rules should be applied to the correct document and proposition; they do not automatically prove every warranty, indemnity or completion-accounts issue.
Commercial sale defect notices have their own structure. A merchant buyer must notify an evident defect within the special statutory period. If the defect was not immediately evident, the buyer must examine and notify within the commercial-sale framework to preserve its rights. Whether those provisions apply to the particular asset, share transaction or contractual warranty theory requires a scoped analysis. This guide does not convert every post-closing corporate dispute into a sale-of-goods defect case.
Authority is equally important. A Turkish joint stock company is generally managed and represented by its board. Representation may be delegated subject to statutory conditions, including retention of at least one authorised board member, and joint signature is the default. Internal limits generally cannot be invoked against a good-faith third party except for the registered and announced head-office, branch or joint-signature limitations recognised by law. Board resolutions, signature circulars, registry records, powers of attorney and delegations should therefore accompany settlement, waiver, notice and arbitration decisions.
6. Build the evidence file around disputed facts, not document volume
Civil proof focuses on disputed facts capable of affecting the resolution. A party has a right to prove its case, but it must use evidence within the prescribed procedure and periods. Evidence obtained unlawfully must not be considered. The general burden lies on the party deriving a favourable legal result from the asserted fact unless a special burden rule applies. A useful evidence plan therefore connects each contractual element to a lawful source of proof and identifies who holds it.
The statutory concept of a document is broad. Written, visual, audio and electronic data, together with similar information carriers, may qualify. For a post-M&A dispute, relevant material may include signed transaction documents, data-room indices, disclosure correspondence, board papers, completion ledgers, bank records, ERP exports, tax files, email, messaging records, expert models and audit workpapers. Collection should preserve provenance, access controls, time information and an explanation of how the record was generated.
A party holding documents relied on by either side must produce them, including electronic documents in a reviewable form ordered by the court. Where a requested document is necessary and statutory possession indicators exist, the court must give a definite production period. Failure to produce without an acceptable excuse, or refusal of the statutory oath, can allow the court to accept the opponent’s account of the document’s contents according to the circumstances. These consequences make early preservation and candid possession mapping more valuable than a late search.
The evidence file should also separate calculation from legal assumption. A financial expert may apply the agreed accounting hierarchy, while counsel identifies the contractual premise and the decision-maker’s jurisdiction. A clean working paper states its source, formula, adjustment, disputed assumption and relationship to the pleaded remedy. It should not silently mix purchase-price arithmetic with damages, interest, penalties or tax effects.
No verified chronology, payment ledger, expert calculation or loss evidence was available for this package. No transaction-specific high-court case corpus was retrieved, and no case holding is asserted. Those are open limits, not gaps to be filled by inference.
7. Interim relief is a preservation tool, not an early merits award
Under the Code of Civil Procedure, an interim injunction may be available where change or delay threatens acquisition of the disputed right or creates a risk of serious harm. The applicant must state the ground and requested form clearly and approximately prove the justification on the merits. In a post-closing dispute, possible subjects may include a disputed asset, a release instruction, records or conduct affecting the claimed right, but the appropriate measure depends on the actual case.
The requested order should be proportionate and connected to the dispute. A party should identify the right requiring protection, the threatened change, the urgency, the evidence supporting approximate proof and the practical operation of the order. A request framed as a final payment or ownership determination may exceed the protective function. Security, jurisdiction and enforceability require case-specific assessment.
An arbitration agreement does not by itself prevent a party from requesting interim relief or provisional attachment from a court before or during arbitration. Making that request does not breach the arbitration agreement. An arbitral tribunal may also order interim relief where the parties have not agreed otherwise and may require security, but its statutory power does not extend to measures requiring public enforcement or binding third parties. Counsel should decide whether court, tribunal or coordinated relief is appropriate rather than assuming one forum is exclusive.
Escrow issues illustrate the need for precision. The entitlement to release funds depends primarily on the executed escrow agreement, the stakeholder’s mandate, the conditions for release and any dispute hold. No escrow instrument was provided here, so this package states no generic right to immediate release or continued restraint. The same caution applies to guarantees and holdbacks.
8. Test the arbitration agreement before planning the merits
An arbitration agreement submits all or selected disputes from an existing legal relationship to arbitration and may appear in the main agreement or a separate document. The writing requirement can be satisfied through the signed-document, exchanged-communication, electronic, unopposed-pleading or incorporation routes stated by law. A clause review should identify the parties, scope, seat, institution, rules, language, tribunal formation and governing law.
Substantive validity is tested under the law chosen for the arbitration agreement or, absent that choice, Turkish law. If court proceedings concern an arbitrable dispute covered by a qualifying arbitration agreement, the defendant may raise the arbitration objection; where accepted, the court dismisses the case on procedural grounds. Timing matters. A party should preserve the objection rather than litigate the merits inconsistently and assume the clause will remain available.
For international arbitration seated in Türkiye or otherwise within the statute’s scope, parties may choose procedural or institutional rules subject to mandatory provisions. Without agreement, the tribunal applies the International Arbitration Law. The tribunal must give equal rights and an opportunity to present claims and defences. A proposed amendment or expansion can be refused because of timing, unfair difficulty or scope, and it cannot exceed the arbitration agreement. These rules make the initial notice, answer and procedural timetable important to claim architecture.
On the merits, the tribunal applies the contract and the parties’ chosen substantive law, using relevant commercial usage in interpretation. Without a choice, it applies the law of the state with the closest connection. Governing law should not be inferred from the seat or institution alone. A Turkish-law SPA may contain a foreign-seated arbitration clause; a foreign-law SPA may direct certain Turkish mandatory or corporate questions back to Turkish law. Each layer requires separate analysis.
Foreign-law, treaty, recognition and enforcement questions also require a jurisdiction-specific record. This guide does not state that an eventual award will be recognised or enforced in a particular country. That work begins with the seat, award, parties, assets, applicable treaty and local enforcement law.
9. ISTAC clauses bring institutional rules but do not answer the contract dispute
Where parties agree to resolve disputes under the Istanbul Arbitration Centre Rules, the arbitration is governed procedurally by those Rules. The clause should still be checked for the seat, language, number of arbitrators, governing law and any expedited or emergency mechanism. Institutional administration does not cure an uncertain scope or bind a non-party without a legal basis.
An ISTAC tribunal may decide objections concerning its jurisdiction or the validity of the arbitration agreement and assesses the arbitration clause separately from the main contract. This competence-competence and separability framework matters where one party attacks the SPA while another relies on its arbitration clause. It does not predetermine the outcome of the jurisdiction objection; the tribunal must apply the relevant agreement and law.
The sole arbitrator or tribunal must act fairly and impartially, respect equality and protect each party’s right to be heard. Participants must treat the arbitration as confidential unless the parties agree otherwise, and the tribunal may order measures protecting secrecy and confidential information. A confidentiality protocol should address the data room, personal data, commercially sensitive calculations, expert materials and any court application that may become public.
On the merits, an ISTAC tribunal applies the parties’ chosen rules of law or, absent a choice, the rules it considers appropriate. The SPA remains the central instrument for price adjustment, warranty, indemnity and limitation questions. Institutional rules organise adjudication; they do not supply missing accounting policies, change the disclosure standard or guarantee recovery.
A practical case plan aligns the dispute notice, tribunal constitution, document preservation, expert work and any court relief. It also budgets translation and service needs. None of those steps should be presented as ensuring a particular timetable or result.
10. Resolve the eight open questions before making a case-specific recommendation
G01 — transaction documents. No executed SPA, disclosure letter, completion accounts, escrow agreement or side letter was supplied. The first review must establish the complete signed hierarchy, amendments and incorporated schedules. Without it, allocation of risk, accrual, notice requirements and remedy restrictions cannot be determined.
G02 — chronology and loss. No verified closing chronology, notice record, payment ledger, expert calculation or loss evidence was supplied. A dated event table should distinguish signing, satisfaction of conditions, closing, account delivery, objection, cure, payment, discovery and procedural steps. It must use actual records rather than reconstructed assumptions.
G03 — decisions. No transaction-specific official high-court decision corpus was retrieved. This guide therefore makes no claim about a judgment’s holding or about how a court will construe a particular clause.
G04 — escrow. Release mechanics depend on the executed escrow instrument and stakeholder mandate. The reviewer must identify the fund holder, trigger, dispute notice, partial release, security, governing law and forum. There is no generic release entitlement.
G05 — valuation. Purchase-price formulas and accounting policies are contract-specific. The financial model must identify each input and contractual source. This package expresses no valuation result.
G06 — cross-border enforcement. Foreign law, treaties and recognition or enforcement require a separate record for the seat, award and asset jurisdiction. No cross-border enforcement outcome is stated.
G07 — time. Statutory periods mentioned in official legislation are general rules. Contractual periods, service, accrual, interruption and procedural steps must be applied to verified dates. No personal final day is calculated.
G08 — currentness. The five official sources were rechecked on 4 October 2026 and matched the archived official files byte for byte. Later use still requires a fresh currentness review.
11. Frequently asked questions
No. A completion-accounts process usually applies the SPA’s formula, accounting hierarchy and expert mechanism. Damages, indemnities, penalties and setoff are separate routes unless the agreement connects them. The signed documents and actual disputed item determine the classification.
Possibly, but the statutory elements and the SPA must be tested. Reciprocal obligations must be capable of setoff, the counter-receivable may be disputed, and notice is required. Contractual restrictions, maturity and the nature of the asserted claim can change the result.
No. The warranty wording, disclosure, causation, loss measure, exclusions, cap, basket and exclusive-remedy provisions require review. The Code’s breach rules do not eliminate the need to prove the legal and financial elements of the chosen remedy.
A release can extinguish debt wholly or partly, but its parties, defined claims, reservations and relationship to unknown matters must be read exactly. Signing a document called a release does not establish that every later claim was waived.
No. Default, cure, statutory exceptions, election, fault and the remedy structure must be analysed. Rescission carries restitution consequences and may be operationally complex after control and assets have transferred.
An arbitration agreement does not prevent a qualifying request for court interim relief or provisional attachment. The applicant must still establish jurisdiction, the statutory threshold, approximate proof and a proportionate measure tied to the disputed right.
A tribunal’s interim power is limited. Under the Turkish international arbitration framework it may not issue measures requiring public enforcement or binding third parties. Court assistance and the third party’s contractual position may need separate analysis.
No. Institutional rules and substantive governing law are separate choices. The tribunal applies the parties’ chosen rules of law or, absent choice, the rules it considers appropriate under the ISTAC framework, while the International Arbitration Law contains its own applicable-law rule.
Electronic data may qualify as documents, but relevance, provenance, lawful collection, completeness and procedural production requirements remain important. Evidence obtained unlawfully must not be considered by the civil court.
Preserve the signed transaction suite, disclosure materials, board authority, closing record, notices and service evidence, ledgers, completion models, underlying accounting data, payment records, data-room index and relevant communications. Build a chronology and do not calculate a personal deadline without verified accrual and service facts.
12. Official sources, scope and publication limits
This guide is bound to five official sources: the Turkish Code of Obligations No. 6098, the Turkish Commercial Code No. 6102, the Code of Civil Procedure No. 6100, the International Arbitration Law No. 4686 and the ISTAC Arbitration Rules. The research package records the exact archived bytes, extracted text, support components and currentness status. Publication-day verification on 4 October 2026 matched all five current official files to the archived bytes.
The guide is general information for a foreign buyer or seller assessing a Turkish-law or Türkiye-connected post-closing dispute. It does not create a lawyer-client relationship, calculate a claim, state that a notice is timely, or promise payment, release, injunction, jurisdiction, award, recognition or enforcement. A case-specific review requires the complete transaction documents, chronology, evidence, parties, governing law, forum, seat and asset picture.
This article provides general legal information. It does not replace advice based on the executed transaction documents, verified chronology, evidence, governing law, forum, seat and asset position.
