Cudjoe Key, FL Estate Planning Law Firms & Lawyers

I assume you are in California. Under this assumption, the power of attorney expired upon your mother's death. Your brother had no power to do anything pursuant to the power after that time. You need to speak with an attorney who handles probate matters, and provide him or her with all the documents you have, so that you can get some advice as to whether it makes sense to proceed against your brother or other person. The fact that your mother passed away 10 years ago may make this very expensive and difficult to pursue (and indeed, may make it impossible due to the statute of limitations), but it is impossible to tell that without a complete review of your situation.

It would depend on the circumstances. You should have the facts and situation reviewed by an estate planning and or criminal attorney if it necessitates.

Your dad passed away and left everything to your Mom. Now it's her money. She can do what she wants, unless there was a WRITTEN contract between mom and dad not to change their wills. It sounds like you may have an "undue influence" claim against nephew, if he induced mom to sign a new will while she didn't have capacity. Get a lawyer working on that now.
