Arizona law allows you to change or revoke your will at any time. You can do it by performing a revocatory act, such as tearing apart, burning, obliterating, or making unreadable all or any parts of your will. Also, you could create a new will and include a clause that mentions that this new will revokes the previous one. Alternatively, you could make a codicil to your current will. A codicil is an additional document that acts as an addition to your will. you can write it explaining what you want to change or remove from your will, sign it, have 2 witnesses sign it as you did with your will, and then keep both documents together. Upon your death, both documents will be read and interpreted together.
