My girlfriend and I moved into her aunt's home when she decided to move to another state last year. We pay for all the expenses of the place and have no legal lease with her aunt or her father and do not pay rent to either of them. Her father has recently obtained POA over her aunt's property and is threatening to evict me if I do not get a real job. I'm running a small under-the-table home business out of the home and I pay half of the rent and expenses in cash to my girlfriend so there isn't really any documentation recording my payments.
Does he have the grounds to evict me even though he knows I pay for half of the expenses to live there?
Can you evict someone you have no lease with?
Is not having a real job grounds for eviction?
This whole thing has turned into a real headache and my girlfriend and I are about to just say f-it and move out. But, we really like this place and don't wish to leave if we don't have to. Is there any way to defend myself if he comes by with an eviction notice and the sheriff?
