Changes made to an existing Last Will and Testament document should be witnessed and notarized to ensure the validity of the changes to others, after the death of the Will’s maker.
Since the process for changing an existing Will requires these steps, creating a new Will is often a better strategy for making updates to the content of a Will document.
Information like an address change should be revised as necessary.
