Hello everyone. I know this question has been asked as I saw several topics about it but I didn't find one that is exactly like my situation.

I purchased a mobile home and set it up on my father's land. I am the one who signed the paperwork for the house and I am the only one who technically is responsible to make payments. I agreed to let my girlfriend move in with me and as soon as the home is inspected and approved we can move in. Recently we have been going through some rough times. My dad and I are concerned that if we end our relationship she will have some claim to the house. My dad works for a division of law enforcement and said that she may try something as drastic as putting bruises on herself and claiming physical abuse. If I pay all the bills and keep receipts can I just evict her, if just asking her to leave isn't enough. We live in North Carolina if it matters.

You need to check if NC is a community property state. That might have a bearing. Otherwise, she's a guest in your home. However, if she establishes it as her official residence she would need to be formally evicted.

Yes, she could pretend abuse, but the only thing that would get her is to temporarily get you out.

Is this the correct definition of community property state?
A method for defining the ownership of property acquired during marriage, in which all earnings during marriage and all property acquired with those earnings are considered community property and all debts incurred during marriage are community property debts. Community property laws exist in Arizona, California, Idaho, Nevada, New Mexico, Texas, Washington, and Wisconsin.

If so, I don't see how it would affect us being we aren't married (and NC doesn't recognize common law marriages unless they were done in a state that does recognize them) and NC isn't one of the 8 states where community property laws exist.

Good points
