Roseville, CA estate planning & probate attorney Kristin M. Kaminski talks about trust administaion. Trust administration is the process that takes place when the trustor or trust maker passes away. Following the trustor’s death, the successor trustee steps into the role of trustee, overseeing the assets of the trust maker. This entails an administrative procedure to transfer assets to the beneficiaries or allocate them to the sub-trusts, following the guidelines specified in the trust document. The trust administration process mandates compliance with specific laws and provisions outlined in the trust, which are imperative for the trustee to follow.
