Sure you could sue for recovery if you have the evidence to support the claim sufficiently.

While the language of your agreement seem very clear and complete, the real question is would they be fully upheld or would they be deemed as to...

First you should have been preparing to go since your ex left in aug 22... The best you can do is at hearing argue that you are/were a tenant...

Without being his attny there is nothing YOU can do to help him. However if he was not given a notice to vacate before the apt filed for eviction...

Yes, if you had agreed to provide 30 days notice and did not, you would be responsible for 30 days of rent and now any other charges that may arise...

If there is an issue you may have to sue him to recover anything you have paid.

A landlord can not increase the rent during a term of rental, but with proper notice they can increase the rent at a natural break in the rental term.

File a small claims action and pray that they pay any judgement you might recieve... good luck.

Mr. Busch provides a great answer.... but breaking in is almost always a bad answer.

Soliciting represntation heres is against the terms... use the find a lawyer feature and directly solicite
