I want to remove my brother as a POA and trustee from my mothers special needs trust. he has repeatedly transferred funds into his own acct without notifying the rest of us. e has paid it back but does it without our knowledge or consent or our mothers consent. is this elder abuse? There are 5 siblings, all have legal equal rights. My mother is still of sound mind. do i need to have the SNT rewritten or just have an addendum written?
