Can a landlord evict a tenant just because they go to jail for a few months if family members are continuing to pay the rent?

Question Details:

My daughter's father had a verbal agreement with manager of trailer park. If her father rehabbed a trailer he could get the title to the trailer he was living in. The work was done but the manager had not given him the title; he kept putting him off. I am going to file a small claims case on that matter. But a few weeks ago her father went to jail and will be in there for a few months. We told the park we would pay the lot rent for him because we didn't want him to loose his trailer. But the manager said he was kicking him out. His girlfriend was still there but the manager just told her to get out. Important Notice
