Interest and Penalty Clause Claims: Legal Processes and Rights

1. What Are Interest and Penalty Clauses?

Interest and penalty clause claims are financial obligations imposed to protect creditors' rights in debt relationships.

Interest is compensation paid to the creditor due to delayed payments.
A penalty clause is an additional compensation agreed upon in a contract for non-compliance with contractual obligations.

These claims typically arise in commercial contracts, loan agreements, lease agreements, and work contracts.

2. Types of Interest and Legal Basis

Interest is considered an additional cost incurred due to delayed payments. In Turkish law, interest is classified into different categories:

a. Statutory Interest (Legal Interest)

According to the Turkish Code of Obligations, if the contract does not specify an interest rate, statutory interest applies.
As of 2025, the statutory interest rate is set at 9% annually.

b. Default Interest (Late Payment Interest)

Applies when the debtor fails to pay on time.
In commercial transactions, default interest is determined based on the Central Bank’s discount rate.
It can be applied without prior notice if explicitly stated in the contract.

c. Commercial Interest

Applies to debt relationships between businesses.
The commercial interest rate is freely determined by the parties.
If not specified in the contract, the Turkish Commercial Code governs its application.

3. What is a Penalty Clause, and When Can It Be Claimed?

A penalty clause is an additional compensation that a party must pay for breaching contractual obligations.

For a penalty clause to be legally valid, the following conditions must be met:
✔ A written contract must exist.
✔ A breach of contract must have occurred.
✔ The penalty amount must not be excessive (otherwise, the court may reduce it).

Penalty clause claims commonly arise in the following situations:

In work contracts, if the contractor delivers the work late,
In lease agreements, if the tenant fails to vacate the property on time,
In sales contracts, if the product or service is delivered late or defectively,
In employment contracts, if the employee resigns before the agreed term.

If the penalty clause is explicitly stated in the contract, the responsible party is obliged to pay without objection.

4. Legal Procedures for Interest and Penalty Clause Claims

If a creditor seeks interest or penalty clause claims, they may pursue legal remedies to collect their dues.

a. Sending a Legal Notice (Demand Letter)

A written notice is sent to the debtor via a notary or legal representative.
The notice should include interest and penalty clause claims.
If the debtor does not pay, legal proceedings can be initiated.

b. Initiating Debt Collection (Enforcement Proceedings)

If the debt remains unpaid, debt collection proceedings can be initiated through the enforcement office.
If the debtor does not object within 7 days, enforcement continues.
If the debtor objects, the creditor may file a lawsuit to annul the objection.

c. Filing a Lawsuit (Compensation Claim)

The creditor may file a lawsuit in the Civil Court of First Instance for interest and penalty clause claims.
If the penalty amount is excessive, the court may reduce it.

5. Statute of Limitations for Interest and Penalty Clause Claims

Debt claims are subject to statute of limitations. If a creditor does not act within the specified period, they may lose their right to collect the debt.

Type of Debt	Statute of Limitations
General interest claims	10 years
Default interest claims	5 years
Penalty clause claims	10 years
Commercial interest claims	5 years

Once the statute of limitations expires, the right to claim interest and penalties is lost.

6. Court's Authority to Reduce Excessive Penalty Clauses

According to the Turkish Code of Obligations, courts may reduce excessive penalty clauses if they are deemed unfair.

If the penalty clause amount is disproportionately high compared to the breach, the court can lower it to a reasonable level.
