A California Affidavit — Change of Trustee is a legal document that is used in the state of California to change the trustee of a trust. This document is commonly used when the trust's original trustee can no longer serve in that capacity, or when the trust's beneficiaries or settlers decide to appoint a new trustee. The document must be signed and notarized before it is legally effective. There are two main types of California Affidavit — Change of Trustee: a revocable trust change of trustee affidavit, and an irrevocable trust change of trustee affidavit. The revocable trust affidavit is used to appoint a new trustee to a revocable trust, while the irrevocable trust affidavit is used to appoint a new trustee to an irrevocable trust. In both cases, the affidavit must include the details of the trust, and the name of the new trustee, the date of appointment, and the name and address of the original trustee.
