Rent from my daughter's no-good former boyfriend

[Funnyman]

My daughter's creepy boyfriend moved into her apartment with her. We own the apartment. He paid us $700/month rent sporadically, and finally moved out when the relationship ended (there is a God...). He made 16 payments over 24 months. We never had a formal contract.

Can I sue him for the missed rental payments?

if you never had a formal contract or verbal agreement, it will be hard or impossible to prove he owes you. Your daughter is responsible for at least half the rent. Who exactly was on the lease?
