You could try to sue him over any claimed damage to your personal property, but as far as beyond that... your mom is the owner and you need to...

I can not understand what you are trying to say or ask.

You can not be evicted unless you have breached the terms of the lease in a material way (usually payment issues). This does not sound like it...

If you do not leave the landlord can then file a suit for eviction and any past rent.

Both answers are correct... civil maters do not recieve a free attny if you can not afford one.

Once the lease ends the landlord if free to offer it to whomever they choose. You should talk to them and see.

Can not provide an answer without more or clearer information.

I dont see any kind of question here.

In the end does it matter? There is still a month with unpaid rent (likely every month since the first time until now). This issue is likely...

If he is considered a tenant then he would be entitled to notice of termination and the legal eviction process if he fails to leave.
