How is a Trust executed?

If your father suffers from dementia, is he only suffering from it time to time or has he been declared incompetent? If he is still competent (of sound mind), he can go to the bank, along with the trust documents, and ask the bank account be renamed and rerouted to the trust. It will be usually his name as trustee for whatever name the trust is. If you are the power of attorney and he is completely incompetent, you need to bring him, the power of attorney, and the trust to the bank and go through the same process. Review the trust documents with a trust/estate planning attorney because there may be other assets that should and could go into the trust (other accounts, retirement monies, vehicles, homes, boats, personal property and the like). You may wish to also explore medical power of attorney and medical directives in addition to the general power of attorney.
