Check your states laws as each state is different, they are on line at your states Dept of Consumer Affairs. In most states you can have them arrested IF you post no trespassing signs, some states require the type with the states penalty for trespassing on them to be posted where its clearly visible a certain distance from the property, and on more than one side. Then take a date/time stamped photo, to prove they are trespassing. Call the police about trespassers, often have wittiness, and take them to court, if you find a new place but according to your state they may or may not be able to then ask you to leave with ot without damages paid to you. Always get a move out inspection and an approval letter releasing your deposit then, or itemized list of what each item they will be deduction from your deposit. Seems you should pay the Mr instead of the Ms. Or make the check or money order Do not pay cash out to Mr and MRS so they both must Sign to cash and ALWAYS put RENT on the payment form.
