Thank you for the additional information. If he is not keeping up with the rent, the landlord will likely proceed with eviction
and then would sue him and possible your daughter, for any damages
suffered. The only way she can be released from liability on the lease, is through the consent of the owner/landlord. She can try contacting the landlord and see if he/she would agree to a penalty for breaking the lease and possible seeing if the boyfriend would cooperate in doing so, agreeing to move out as well, to resolve the situation. If she is moving back home with you and does not need to go back to the rental, she should not, to avoid any additional problems. If she is on the lease and has a key, I am not sure how he is preventing her from accessing the duplex but she can always call the police if she needs to, since she does have a legal right to be there. I know she does not want to be involved at all with the lease but it is the landlord who has the discretion to release her, so she would need to deal with them.
