“acuerdo (o convenio) of liquidacin” would refer to the billing of an account such as the payment of your credit card.B.

I found these terms on the Internet in legal documents and legal dictionaries. A Costa Rican also confirmed that “arreglo conciliatorio” is the term used when a civil trial is settled. This question has already received an answer and evaluation. It is therefore not possible to provide new answers.
