Legal Question in Wills and Trusts in California

I am sorry for your loss.

Neither is enforceable, because when your father died, the durable power of attorney ended.

You also state you have two wills. Which one is the last one signed. Are there two witnesses, and not a notary? Does the last will state that he revoked "all prior wills" or some language to that effect?

I suggest you contact a local probate attorney to review the documents and to determine how his estate would be distributed.

Again, my condolences on the loss of your father.

You are mixing up legal terms. A power of attorney is automatically revoked upon the death of the person who signed the power of attorney. A will takes effect when the person who made the will died.
