I have a roommate who has not paid rent and has caused me to be late by 15 days, nearly come to eviction.

I have currently locked the door to the house which he cannot enter until he pays for his delinquent rent amount.

Now, he isn't on lease and no contract was made, but there are messages of promised money and so forth between us.

He is 29years old. However, my question is am I allow to pawn his belongings for the delinquent amount of rent that he owes?
