Landlord breached lease...?

[Jessica Wygal]

I have a client who I’ve worked with on two rentals. Her lease was up today (7/31) though she moved her stuff out on 7/26. She had a couple of pieces of mail delivered and a package yesterday...when she went to pick up she discovered the locks had already been changed and a new tenant had already moved in (before her lease/60 day notice was up technically). Does she have any recourse? Your thoughts on filing a civil suit...?
