An agreement letter between two people is a document that outlines an understanding between two parties about a specific issue or transaction. It generally contains the expectations, rights, and duties of both parties, as well as any relevant details related to the agreement. A well-crafted agreement letter should be clear and detailed so that it can be easily understood by both parties. It should be written in a conversational tone to help foster communication and trust between the two parties. Ultimately, an agreement letter between two people serves as an important record of the parties’ understanding, so it should be kept safe and accessible for future reference.
