The more learned reading replys tonight , to my situation , I can honestly say No it was not a good idea. Can't blame anyone but myself for not using my brain and researching or at least asking for advice and using common sense . Maybe this discussion can be useful to others. Thank you for all replysAnd you thought that was a good idea?
The worse part of the bad idea.
All other things being equal, you can invite anybody you want on to or in to the property you occupy. Though if your invitees are doing damage to the land owner's property, that's another story.
Ultimately, yes. You and your partner are tenants. Your tenancy can be terminated. It would probably require a longer notice period since it's a mobile home.
If mother convinces daughter to get a restraining order against you then, yes, you can be removed from your own home and it's likely the police or sheriff will remove you with only a few minutes notice.
Beyond that, the mother's attempts to control or demand are nothing but hot air (except for potential termination of tenancy) and you are free to ignore them.
I would hope that your partner is taking your side against the mother. If not, then your relationship is doomed and you'd better come up with an exit strategy that preserves your stake in the mobile home.
Explain how all this strife got started.
