Final answer:
To make a minor amendment to a will, the testator should create a codicil, which is an additional document that modifies the original will and must be executed with the same legal formalities.
Step-by-step explanation:
A testator who wants to make a small change in her will can do so by adding a codicil. A codicil is a supplementary document to an existing will that modifies, explains, or adds to its provisions.
It's important to note that a codicil must be executed with the same formalities as a will, meaning it typically must be written, signed, and witnessed according to the laws of the jurisdiction where it is created.
Because the execution of a will is a very public process, with the final document being available for public record, it's essential that any changes made through a codicil are also clearly documented to ensure the testator's true intentions are followed. It's worth mentioning that a will and any of its codicils can be contested or challenged in court, particularly if there are doubts about their validity.
