My girlfriend lives in Maryland and wants to move to Colorado so we can be together and get married and have a life together. We've saved up quite a deal of money to rent a place together. Her mother is her PoA, and with her moms mental state, being she is severly bipolar and has PTSD, she doesnt fully trust her mom and she thinks her mom might try to pull legal actions on her if she moves even though she's said like, "you can make your own decisions" and "I'll give advide but I'm not helping financially". So I would like to know does her mom have the authority to pull legal actions if my girlfriend chooses to move to Colorado?
If your girlfriend is competent, she can have the POA revoked. And if competent, she can do whatever she wants. There is so one who can stop ur girlfriend unless there is a guardianship in place.
Please do an online search for the specific POA for her state. This will help you and her understand exactly what this document is, exactly how and when it comes into consideration and exactly how it can be changed.
Unfortunatly you have not provided enough specifics for anyone here to be of any real help. Have your girlfriend send you a copy of the document in its entirety and both of you do your homework. This will ensure that you both know what you are dealing with.
If your girlfriend is competent (in the legal sense), she can annul the power of attorney.
If she isn't, and besides the mother's mental fragility there are factors in this which you haven't yet mentioned, then the mother may well be able to block decisions your girlfriend makes which the mother believes are not in your girlfriend's best interests.
It is quite unusual for an older adult to have power of attorney for her adult child; we're used to things being the other way round. There are, of course, many types of POA but not so many that the principal can't change whenever she likes. So - what's going on? What haven't you told us?
