Step-by-step explanation:
True, written service agreements must clearly indicate the names of all parties to the agreement. This is essential to ensure the validity and enforceability of the contract. When drafting a service agreement, it is a standard and crucial practice to clearly state the names of the parties involved so that there can be no confusion or dispute as to who has agreed to what terms and conditions. The names confirm who is legally bound by the contract and are used to identify the entities or individuals who may enforce the contract or be subject to legal action if the terms are breached.
