Yes. In fact, it’s best practice to review your Will regularly, especially after significant life events such as marriage, divorce, or the birth or adoption of children.
To make minor changes to your Will, you can use a document called a Codicil. This can add, delete, or change an instruction in your Last Will and Testament without invalidating it.
However, if you need to make extensive changes, it’s best to create an entirely new document that includes a clause revoking any prior Wills you created. LawDepot’s Last Will and Testament template automatically includes such a clause, so there's no confusion about your most current intentions.
