Legal Question in Administrative Law in California

A lawyer would need more information to give you a useful answer. Some of the additional questions that arise upon reading your question are:

(1) How old are you now?

(2) Do you have a copy of the instrument that established the (supposed) trust?

(3) What was the nature of the fight between your uncle and your stepmom, i.e., was it in court?

(4) Are uncle and stepmom still around?

(5) What is your sister's position in this?

(6) Is there any indication that your uncle has squandered your trust?

I recommend that you see a local wills, trusts and estates attorney for an initial (usually free) consultation, taking with you any documents you might have re the creation and/or existence of the trust, your father's will, any death records you may have, and any documents regarding the fight. The law provides substantial protection for the beneficiaries of trusts and imposes serious duties upon trustees.
