Legal Question in Wills and Trusts in Florida

First you have to understand that under Florida law, a parent can disinherit a child. So whatever you do, be careful.

Second, if the word Trustee is used, then it implies a Trust was created, and it is your mother's sole right to choose who gets what, and who is in charge. Hurt or not hurt doesn't make a difference, so you will have to live with it. Who runs it is not necessarily a reward for doing good, its your mother's decision as to who is most capable to see to her objectives. She may have provided for income to a beneficiary for life, and not necessarily the principal. So be prepared to accept that. You are not entitled to a copy of the Trust until your interest vests, or your mother approves it.

Third, unless your brother has used some sort of "undue influence" over your mother, or your mother is of "diminished capacity" you pretty much have to live with what she does.

Fourth, the reason you and your brother are not co-trustees seems obvious. You don't get along, and it would be disasterous to make you co-trustees. So I'll bet your mother had to make a call that one or the other ran it, and your brother won. If the two of you got along, it probably would have been different.

Finally, when your interest in the Trust or Estate vests, after your mother's passing, you are entitled to accountings. Then if you don't like how he handled the accounts you may be able to do something. You may not find your brother trustworthy, but your mother (who calls the shots) does.
