Modification

How do I change my will after it's already been signed?

You can modify your will through a codicil (an amendment) or by creating an entirely new will that revokes the old one. A codicil must meet the same execution requirements as your original will, including proper witnessing and notarization where required by your state. Many people find it simpler to create a new will rather than adding multiple codicils, as this reduces confusion and ensures all changes are clearly documented in one place.
