There are two ways to revoke a will. First, you can revoke an older will by a new will. So your new Will will say “I revoke all my previous wills.” The second way is by physical act. My personal favorite. You can tear up the will, you can write void all over it, you could burn it. There’s a lot of case law regarding this. The important thing is that the physical act is done by the testator, the person who created the will, or by someone at the testator’s direction. So, for example, I tell my brother, “Rip up my will!” And he does so in my presence. And those are two ways you can revoke your will.
