Article 39 of Law of Evidence

In non-commercial matters, if the value of the legal act exceeds five thousand dinars or its value is unspecified, witness testimony shall not be admissible to prove its existence or extinction unless there is an agreement or a provision stipulating otherwise. The obligation shall be valued by reference to its value at the time the legal act was made, without adding accessories to the principal. If the action comprises multiple claims arising from multiple sources, proof by witness testimony shall be permissible for each claim whose value does not exceed five thousand dinars, even if those claims collectively exceed that value, and even if they originate from relationships between the same litigants or legal acts of the same nature. In proving partial payment, regard shall be had to the value of the original obligation. )2(
