It's time that your father had an AB trust set up. What that is, is at his death, all of his assets went into the A trust. Your stepmother is the beneficiary of the a trust. She is allowed to use those assets in her lifetime, until her death when everything passes to the B trust. You must be the beneficiary of the B trust, because she says it you don't see a copy of the trust until her death. Hang tight, you will get your assets soon enough.
