Disputes on Checks and Bills of Exchange: Objections to Signature, Objections to Debt, Liability Regime, Evidence and Application (in Light of Doctrine and Jurisprudence)

DISPUTES IN CHEQUES AND NEGOTIABLE INSTRUMENTS: OBJECTION TO SIGNATURE, OBJECTION TO DEBT, LIABILITY REGIME, PROOF AND APPLICATION (IN LIGHT OF DOCTRINE AND CASE LAW)

1. Introduction: Function of Negotiable Instruments and Map of Disputes

Negotiable instruments (cheque, promissory note, bill of exchange) are types of commercial paper that respond to the need for "fast and secure payment/financing" in commercial life, standing out with features of transferability, formalism, and abstractness. While the economic function of these instruments provides the creditor with a powerful collection opportunity, it also generates serious risks for the debtor due to formal validity of the instrument and the possibilities of signature outside of will, unauthorized representation, and forgery.

The majority of disputes concentrate around two "core defenses":

1. Objection to signature (signature denial / forgery claim): It is asserted that the signature on the instrument does not belong to the debtor. This defense fundamentally shakes the binding force of the instrument with respect to the debtor.
2. Objection to debt: While the signature belongs to the debtor, it is asserted that the debt does not exist, has been extinguished, or that enforcement conditions have not been met (payment, release, statute of limitations, venue objection, claim of security instrument, absence of negotiable instrument status, etc.).

These two types of defense produce different results both in the accelerated regime of negotiable instrument enforcement (EBL) and in negative declaratory/recovery actions filed in general courts. In this article, the procedure of signature and debt objections specific to enforcement through negotiable instruments (negotiable instrument enforcement), the burden of proof, liability, and sanction consequences will be systematically examined along the axis of TCC, EBL, CCP provisions, and sample court decisions.

2. Formalism in Negotiable Instruments: Mandatory Elements of Cheque and Promissory Note

For negotiable instruments to function as "negotiable instruments," they must carry the mandatory elements required by law. In this context:

• For a promissory note (order note): TCC Article 776 lists mandatory elements such as the designation "promissory note," unconditional promise of payment, maturity, place of payment, payee, date and place of issuance, and the issuer's signature.
• For a cheque: TCC Article 780 makes mandatory elements such as the designation "cheque," unconditional order to pay, the drawee's trade name, place of payment, date and place of issuance, and the issuer's signature.

In practice, formal deficiency or claims of correction/forgery on the instrument make the negotiable instrument status of the document debatable. In judicial practice, it is particularly emphasized that if changes on the instrument (such as date/amount/place) have not been approved by the issuer with initials or signature, the "correction may be deemed void"; in this case, an evaluation must be made according to the pre-correction state of the instrument (example: the Court of Cassation 12th Civil Chamber's approach requiring signature/initial and forgery-signature examination).

For this reason, the first step when preparing an "objection to debt" or "complaint regarding negotiable instrument status" is always: The instrument text, mandatory elements, and corrections on the instrument must be technically read; and whether there is any unapproved erasure/deletion/alteration must be determined. CCP Article 207, by regulating that unapproved erasures/deletions may not be taken into account in the event of denial, also feeds this debate in general evidence law.

3. Presentment of Cheque, "Dishonored" Notation, and Enforcement Conditions (Law No. 5941 Article 3)

A cheque is, in classical doctrine, a payment instrument "payable on demand." However, in Turkish law, due to the practice of post-dated cheques and the regulations of Cheque Law No. 5941, there is a critical threshold regarding enforcement conditions:

• For legal enforcement to be possible, in most cases presentation of the cheque to the bank within the statutory presentment period and the making of a "dishonored" notation are required (emphasis on Law No. 5941 Article 3/8).
• The bank's obligation to pay a certain amount and how the "dishonored" notation will be made (endorsement on back of cheque, partial payment, etc.) determine both the supporting documents for enforcement proceedings and liability debates in practice.

Within this framework, debtor defenses in cheque disputes are divided into two: (i) The signature on the cheque does not belong to me (objection to signature – primarily absolute defense character) (ii) The signature belongs to me but the cheque is not a negotiable instrument / presentment conditions have not been met / there is a statute of limitations / there is no debt (objection to debt or complaint under negotiable instrument law).

4. Objection Regime in Negotiable Instrument Enforcement: 5 Days, Enforcement Court, and Issue of Suspension of Enforcement

In enforcement by distraint specific to negotiable instruments (within the systematics of EBL Articles 167 et seq.), a payment order is sent to the debtor and "objection warnings" are explicitly written in the payment order. EBL Article 168 explicitly regulates two fundamental objection paths:

• Objection to signature: The signature on the instrument does not belong to me (within 5 days to the enforcement court).
• Objection to debt: Objections such as no debt/paid/statute of limitations/venue (within 5 days to the enforcement court).

The most critical point in this system is: The objection authority is not the enforcement office as in general distraint, but the enforcement court. Furthermore, objections as a rule do not suspend enforcement; only "sale" proceedings may be suspended or the court may issue a "temporary suspension" decision (EBL Articles 169, 170).

Doctrinally, the purpose of this regime is to preserve the rapid circulation and collection function of negotiable instruments; while at the same time granting the debtor limited but effective judicial review. The short duration of periods (5 days) is the direct result of this speed policy.

5. Objection to Signature (EBL Article 170): Legal Nature, Proof, Consequences, and Sanctions

5.1. Subject and Nature of Objection to Signature

Objection to signature is the debtor's claim that "the signature on the instrument is not mine." This claim fundamentally affects the binding force of the instrument with respect to the debtor. In practice, signature denial most often takes the form of "the instrument was forged," "my signature was counterfeited," "the company stamp/signature was affixed without authority," "the endorsement signature does not belong to me."

In court decisions, claims such as "the signature is forged" are most often evaluated under the heading of absolute defense; that is, it is expressed that they may be raised against everyone including good faith holders. This approach is important in terms of balancing the abstractness and circulation capacity of the negotiable instrument with the risk of "forged signature": circulation is protected; but the creation of a debt through a forged signature is prevented.

5.2. Burden of Proof: Who Bears the Burden — The Party Saying "The Signature Belongs to Me" or "Does Not Belong to Me"?

One of the most critical debates in practice is the burden of proof. Where there is signature denial in a negotiable instrument, many decisions and doctrinal explanations rest on the principle that "the burden of proving that the signature belongs to the debtor lies with the creditor." This is particularly pronounced where the instrument is in the creditor's hands and the debtor makes an explicit denial.

For this reason, in signature objection files, the creditor must effectively conduct the processes of presenting the original instrument, obtaining comparative signatures suitable for expert examination, and if necessary obtaining a forensic/graphology report. The debtor party, as early a stage as possible, must bring to the file:

• Signature samples,
• Company signature circulars,
• Authorization documents,
• Banking documents,
• Factual defense regarding when/in what context the signature on the instrument could have been affixed.

5.3. Effect on Enforcement: Is Suspension Automatic?

According to EBL Article 170, objection to signature "does not suspend enforcement proceedings other than sale." However, if the enforcement court finds the objection serious, it may issue a temporary suspension decision based on the documents before the hearing. This is practically very important for the debtor; because proceedings such as attachment, safekeeping, and bank freeze may in fact produce severe consequences in non-sale processes.

5.4. Sanctions: Risk of Denial Compensation and Fine

The "risk-reward" balance in objection to signature is strict:

• If the signature does not belong to the debtor: enforcement is suspended, the debtor is freed from the negotiable instrument enforcement (the creditor's right to file an action in general courts is reserved).
• If the signature turns out to belong to the debtor and enforcement has been temporarily suspended through the objection: denial compensation of not less than 20% plus a 10% fine may come into question against the debtor (EBL Article 170).

Therefore, objection to signature is not a defense to be "automatically raised in every file"; it is a strategy that must be supported with technical examination-suitable indications, a comparative signature set, and factual consistency.

5.5. General Court Dimension: Negative Declaratory/Recovery Action

Although enforcement court decisions are extremely effective from the perspective of enforcement law, in many cases debates on res judicata in the substantive sense and subsequently filed negative declaratory/recovery actions may come to the agenda. For this reason, signature examination results must be evaluated together with the forgery examination mechanisms in the CCP. CCP Article 211 provides for stages such as the judge having the denying party write and sign in their presence and, if necessary, referring to an expert.

6. Objection to Debt (EBL Articles 169, 169/a): Scope, Proof, Documented Objection, and Consequences

6.1. Scope of Objection to Debt

Objection to debt covers defenses other than signature denial. The most frequently seen ones:

• Non-existence of the debt (no underlying relationship, absence of consideration/cause, claim of security instrument, etc.)
• Satisfaction/release (payment, receipt, agreement)
• Extension (extension of maturity)
• Statute of limitations
• Venue objection (enforcement proceedings initiated at the wrong enforcement office)
• Claims that presentment conditions or "dishonored" procedure in the cheque were not correctly carried out
• Absence of negotiable instrument status (missing mandatory element)

EBL Article 169/a particularly emphasizes "proof by official document or document with acknowledged signature" for acceptance of an objection to debt. This makes it difficult to raise an objection to debt "by word alone"; it increases the need for document-based defense.

6.2. Temporary Suspension

If the court concludes from the documents submitted by the debtor that the debt does not exist, was satisfied, is statute-barred, or on grounds such as venue, it may decide to temporarily suspend enforcement before the decision on the merits. This mechanism provides "immediate protection" for the debtor; however, the early submission of a document set that will convince the court is of vital importance.

6.3. Compensation Against Creditor (Bad Faith/Gross Fault)

In the event of acceptance of the objection to debt on the merits, if the creditor is in bad faith or grossly at fault, a compensation sanction of not less than 20% of the amount of the claim subject to enforcement may come into question (EBL Article 169/a). Since this compensation requires proof of bad faith, it is not automatically applied in every case; however, it is debated in situations such as clearly unfounded enforcement, continuation of enforcement despite documentation, and obvious statute of limitations.

7. Absolute Defense – Relative Defense Distinction: Fate of Defenses Against "Good Faith Holder"

One of the most practical distinctions in negotiable instrument law is against whom defenses may be raised:

• Absolute defenses: Directed at the nullity of the instrument; may be raised against everyone including good faith holders. E.g.: forged signature, missing mandatory formal requirement, lack of capacity, unauthorized representation, statute of limitations, etc.
• Relative/personal defenses: Based on the underlying relationship; as a rule, may only be raised against the first payee or related persons; cannot be raised against good faith holders.

In court decisions, it is frequently emphasized that the claim that "the signature is forged" is an absolute defense; and for this reason it may be raised even against the last holder. This explains why objection to signature is considered "the strongest defense" in negotiable instrument law.

8. Forgery/Erasure/Deletion on Instrument, Initials, and Signature Examination: Typical Scenarios in Practice

Another area of disputes frequently encountered in negotiable instruments is the claim that changes were subsequently made on the instrument. Here, two fundamental legal channels work together:

1. CCP Article 207: Unapproved erasure/deletion/alteration not being taken into account in the event of denial; the instrument may even be deemed partially/wholly void.
2. Judicial approach: For a change to be valid, approval by initials/signature of the issuer; in the event of objection, proper signature examination; unapproved correction being deemed void.

In such claims, "objection to signature" and "objection to debt" may intertwine: Because forgery sometimes directly relates to the signature (initial signature); sometimes it generates an objection to debt/status in the form of a claim of change in an element such as amount/date. Strategically, defense petitions must clearly establish this distinction:

• "The signature is not mine" (EBL Article 170)
• "The instrument text has been forged / there is an unapproved correction, its negotiable instrument status in this state is affected" (complaint/objection combination and evidence strategy)

9. Liability Regime and Parties: Issuer, Payee, Endorser, Aval, Representative

In negotiable instruments, liability arises on the axis of signature ownership and representation authority:

• Issuer: The principal debtor of the promissory note/cheque; if the signature exists, is as a rule responsible.
• Endorser: By endorsement, undertakes a negotiable instrument commitment; if the signature does not belong to them, absolute defense comes into question.
• Aval (guarantee-like negotiable instrument commitment): Creates liability through the aval notation and signature; objection to signature is the fundamental defense here too.
• Representation in legal entities: The signature affixed on behalf of a company and authorization may give rise to a "unauthorized representation" defense different from signature denial, and in many cases is debated as an absolute defense.

For this reason, "objection to signature" is not only "I did not sign it"; it is sometimes a defense family that expands as "I was not authorized to represent the company / unauthorized signature" or "the stamp-signature combination is forged/inappropriate."

10. In Lieu of Conclusion: Checklist for Practice (Summary Methodology)

In a cheque/promissory note/bill of exchange dispute, the typical sequence for a sound legal evaluation should be as follows:

1. Instrument type and mandatory elements (TCC Articles 776 / 780)
2. Presentment/"dishonored" notation and enforcement conditions (for cheques, Law No. 5941 Article 3)
3. Type of enforcement and periods (negotiable instrument enforcement – 5 days – enforcement court)
4. Need for signature examination (objection to signature, forgery, initials)
5. Objection to debt documents (strong document set for payment/release/authority/statute of limitations)
6. Risk management: Compensation/fine possibilities in EBL Articles 170 and 169/a
7. Alternative path: Negative declaratory/recovery action and CCP forgery examination mechanism

This methodology enables both creditor and debtor parties to build the correct "defense/claim backbone"; to avoid weak claims; and to proceed with concrete evidence.
