Many trusts will have provisions for the adult beneficiaries to name successor trustees. See if your mom's trust has such a provision. Other trusts permit a trustee to name his successor. If the resigning trustee is capable of doing that, have him name you as the trustee. You will need to do this in the manner required by the trust instrument.
If the trust has no such provision, you will need to petition the court to have a trustee appointed.
