My friend had an irrevocable special needs trust setup. She is the trustor/trustee and her daughter is the beneficiary. The lawyer did not appoint a successor trustee in the trust and my friends knowledge was minimal at the time she had the trust done. The verbiage says in the event no successor trustee has been appointed, a successor trustee shall be appointed by the court of a competent jurisdiction. It also states that the trustee may, from time to time amend this trust agreement to address changes in federal or state law, or other circumstances which may affect this trust and it's beneficiaries. Can we type up an amendment to the trust assigning a successor trustee as would be done for a revocable trust or does she have to have this done by a lawyer?
