I had to do a POA over her affairs as she is barely able to write anymore. While I do have signature rights on the account, I only use it for her bills etc. With pending issues regarding medicaid and such are the assets of that account to be considered part of her assets or is it funds being held for the "Son Doe"?
If the account is a uniform trust for minors account the money is the son's not the trustee's (Jane/Mom). There is however an issue with who is trustee for Son Doe.
