I am the trustee of mommas trust. Have been for 13 years. Also POA for financial and medical. Pay all of her bills for her. Taxes done. Keep good records and save all receipts. Everything that I have done or need advice on I call my attorney and run it by him. My sister told me that my brother said I have broken all kinds of Alabama state laws. Don't know what they would be and my attorney has not told me that I have done so?
He can always hire a lawyer and ask for an accounting if he feels you are using Moms money. If the trust allows you to be paid, I would do it. You don't have to spend it. Put it in a separate acct thats there if Mom should need it. When all is said and done the inheritance is going to be split two ways. You may as well get paid for what u do.
Next time SIL makes a statement like that, ask her what laws does brother think you have broken. Because you will ask your lawyer and see what he says. And if u have broken any laws, you will immediately correct the problem. As my daughter says, turn it back on them.
We here on this forum are not attorneys and even if we were, we couldn't give you any guidance without reviewing ALL of what you've done on behalf of the Trust. Is your brother an attorney for the state of Alabama? Even if he is, he needs to put up or shut up. End of story.
