A promissory note that does not carry the mandatory elements the statute requires is not a negotiable instrument and cannot found enforcement proceedings on a negotiable instrument (Article 776 of the Commercial Code). It becomes an ordinary written document of proof instead. Signing a blank note is the most dangerous thing of all: an amount filled in later stands unless it can be proved that it breached what was agreed.
A promissory note is a document by which a person undertakes in writing to pay a defined sum on a defined date. Governed by the Commercial Code (Law no. 6102), it is among the most widely used negotiable instruments in both commercial and personal dealings — and it produces serious consequences when misunderstood or signed carelessly.
Negotiable instruments differ from other evidence of debt in being documents of title. That gives them particular legal force: what is written on the face of the instrument governs, and the underlying relationship often cannot be examined at all. Signing one is a serious undertaking.
Which Elements Are Mandatory?
Under Article 776, a valid promissory note must contain:
- The word “bono” or “emre yazılı senet” in the text of the instrument, written in Turkish.
- An unconditional promise to pay. Payment must not be made subject to any condition; a conditional promise does not create a negotiable instrument.
- The maturity date. A note that does not state one is treated as payable at sight.
- The place of payment. Where none is stated, the place of issue is treated as the place of payment.
- The name of the payee. A note payable to bearer is possible but subject to special rules.
- The place and date of issue.
- The signature of the maker. Without it the instrument is invalid.
If any of these is missing, the document may be treated not as a negotiable instrument but as ordinary evidence of a debt, and the advantageous enforcement route is unavailable.
| Element | If missing |
|---|---|
| The word for “promissory note” | Not a negotiable instrument |
| Unconditional promise to pay a defined sum | Not a negotiable instrument |
| Maturity date | Treated as payable at sight |
| Place of payment | The place of issue is treated as the place of payment |
| Name of the payee | Not a negotiable instrument |
| Date of issue | Not a negotiable instrument |
| Place of issue | The place beside the maker's name is treated as the place of issue |
| Signature of the maker | Not a negotiable instrument |
In enforcement on a negotiable instrument the debtor's period for objecting is five days and the objection goes to the enforcement court; it should not be confused with the seven days in enforcement without a judgment.
Why Is a Blank Note So Risky?
Among the most dangerous practices is signing a note with the amount or the maturity date left blank.
- The scale of the risk. A signed note with the amount left blank can later be filled in with any figure. Saying “the debt was only this much” creates a serious problem of proof.
- Completion contrary to what was agreed. Where the parties agreed on a particular figure and the creditor entered a higher one, an action to annul the note may be brought — but the burden of proof lies on the debtor, and proving the agreement is difficult.
- Protection of a holder in good faith. If the note has changed hands and the last holder took it in good faith, the defence that it was completed contrary to the agreement cannot be raised against them. That makes the debtor's position considerably worse.
How Are Enforcement Proceedings Brought?
The creditor's strongest weapon is enforcement by attachment on a negotiable instrument:
- Speed. The creditor applies directly to the enforcement office without going to court, and a payment order is served on the debtor.
- The period for objecting. The debtor must object to the enforcement court within five days of service of the payment order (Article 168 of the Enforcement and Bankruptcy Act) — calendar days, not working days. The period is very short, and if it is missed the proceedings become final and attachment follows.
- Grounds of objection. Denial of the signature, payment of the debt, limitation, or completion of the note contrary to what was agreed. Where the signature is denied a handwriting examination is carried out, and if the result goes against the debtor a penalty of 10 per cent for bad faith may follow.
- An objection does not stay the proceedings automatically. Unlike enforcement without a judgment, a stay must additionally be obtained from the enforcement court.
The Action to Annul a Note
- A stolen or lost note. A person who has lost possession may apply to the civil court of peace for annulment. The court may order publication and, if the note is not produced within the period set, annul it.
- A note completed unlawfully. Where it is proved that the note was completed contrary to what the parties agreed, annulment may be sought, and an interim measure may temporarily prevent its use.
- Defective consent. A note signed under duress, by deception or by mistake may be annulled under the general provisions.
- Protection of a third party in good faith. Where the note has been transferred to a third party in good faith, the debtor cannot as a rule raise against them the defences available against the original party. Be careful whenever a note may change hands.
“A promissory note contains the maker's unconditional promise to pay the sum stated in it, at the stated maturity and place, to the holder or the payee.”
— Turkish Commercial Code, Article 776
Fill in the amount, the maturity date and the payee before signing, strike through any empty spaces, and keep a photocopy. Once a note has passed to a holder in good faith, the defence that it was completed contrary to your agreement can no longer be raised.
