What is an amendment referred to in terms of a will?

An amendment to a will is specifically referred to as a codicil. This is a legal instrument that modifies, adds to, or clarifies the provisions of an existing will without the need to completely rewrite it. A codicil must follow similar legal formalities as a will, such as being signed and witnessed, and it serves to ensure that the testator's original intentions can be updated or corrected without starting over completely.

In contrast, a complete rewriting of the will would invalidate the previous version unless explicitly stated otherwise, while a legal disclaimer refers to a relinquishment of rights to an inheritance or property and a testamentary trust is a legal arrangement that dictates how assets should be managed after death. These terms do not represent a method of amending an existing will.
