Quick Guide: Guarantors on Promissory Notes

A “kefil” (guarantor) steps in if the debtor fails to pay. Turkish law recognizes two main structures:

  1. Ordinary guarantee (kefalet): Governed by the Turkish Code of Obligations; requires a written statement, limit, date, and in some cases spousal consent.
  2. Aval: A cambial guarantee placed on the face of the note, making the avalist liable just like the principal debtor.

Why Add a Guarantor?

  • Provides a secondary payer and enhances collection prospects.
  • Helps suppliers extend longer terms safely.
  • Complements other collateral (mortgage, pledge, etc.).

Aval vs. Ordinary Guarantee

  • Ordinary guarantee: Usually on the back of the note; creditor must first pursue the debtor unless waived. |- Aval: On the face of the note with wording such as “aval içindir”; avalist can be sued immediately like the maker.
