Türeli & Ceylan Attorney-at-Law – Debt Enforcement and Commercial Law Services

In everyday life—especially in commercial transactions or trust-based lending arrangements—it is not uncommon for individuals to sign a blank promissory note. While often done in good faith, such a signature can later result in serious legal consequences and potential victimization.

So, what does signing a blank promissory note mean under Turkish law?
What legal remedies are available if the note is misused or filled in unlawfully?
In this article, we explain the legal position of the signatory and the steps that can be taken to protect your rights.

What Is a Blank Promissory Note?

A blank promissory note is a negotiable instrument (kambiyo senedi) signed by the debtor, but without stating essential elements such as the amount, due date, or payee. It is typically signed with the understanding that the missing fields will be completed later in accordance with mutual agreement.

Legal Basis – Turkish Commercial Code (TCC) Articles 688 and 690

Article 688 outlines the required formal elements for a valid promissory note, including:

• The name of the payee
• The amount payable
• The date and place of payment

In a blank note, these details are left empty when signed.

Article 690 – Improper Completion:

“If any blank part of a promissory note, bill of exchange, or cheque is filled out in violation of the agreement, the instrument remains valid. However, the debtor may raise claims of bad faith and fraudulent alterationagainst the party who filled it in.”

What Happens If the Blank Note Is Improperly Completed?

If the note is later filled in with an excessive amount or terms that were never agreed upon, the note:

• May still be legally enforceable as a negotiable instrument
• But the debtor has the right to challenge it by alleging fraud, misrepresentation, or abuse of trust

Court of Cassation (Yargıtay) Precedents:

Yargıtay has consistently held that a debtor retains the right to prove that the note was filled in contrary to agreement. However, the burden of proof lies with the debtor.

What Should You Do If You Signed a Blank Promissory Note?

1. Take a photocopy or photo of the signed document before handing it over
2. Collect evidence of the circumstances of signing (e.g., text messages, emails, written notes, or witnesses)
3. If the note is submitted for enforcement, file an objection within 5 days
4. If enforcement proceedings begin, consider filing a:
   • Negative declaratory lawsuit
   • Objection to debt or signature
   • Criminal complaint for fraud or abuse of trust
5. Contact an attorney immediately for assistance in preparing legal defenses and applications

What If Enforcement Proceedings Have Already Begun?

If the promissory note has been submitted to enforcement, and you receive a payment order (ödeme emri):

• You have 5 days to object to the signature, and
• 7 days to object to the debt itself

Failure to object within this time frame will result in the note becoming final, and seizure of your assets may follow.

Even if signed with good intentions, a blank promissory note carries serious legal risks.
It is critical to exercise caution when dealing with such instruments and to seek professional legal advice immediately if you suspect abuse or enforcement.
