I live with my girlfriend and her mother in NC. We all have separate bedrooms since her mom does not approve of us sleeping in the same room. Can my P.O. search my girlfriend and her mothers rooms?

Hello P:

Yes. But, they CAN lock things up in their own rooms and the PO can't require them to be opened.

Good luck with knowing your rights.
POs often have ways around them, such as deciding that your living arrangements are not suitable, and they can make you move out.
Then they might intimidate others in your house, and imply that they are now under suspicion, blah blah.
excon can probably tell you how to stand tall but I can't.
