👉 Non-revocability in a legal context refers to the inability of an instrument or document to be revoked by another person. In other words, it means that once it is signed or executed, it cannot be altered or changed after its initial signing or execution. This concept is often used to describe something that remains the same as long as it is not modified or altered in any way. For example, a contract signed by both parties cannot be amended or revoked without their consent.
