Ugly Break up with tenants

[James Pezza]

Hey I am new here and to owning a multi family. Currently have 2 tenants who are on the lease together but are undergoing an ugly breakup. Started as he got a restraining order on her with custody of the child. They are on a Month to month lease and he wanted to remove her from it so it was only him. I wanted to wait till after the court date to write up a new lease and was hoping things would calm down. The court date was today and she wants to get her belongings out but he won’t let her. They lifted the restraining order and no new lease has been written. Should I tell him to let her inside and collect her stuff or should I let her contact the police and go through small claims courts and stay out of it and leave the old lease intact till then. Just don’t know if I should sit in the side lines or get involved. Thank you all
