If your property is a single dwelling home, the process will be as easy as pie. If your property is a multi-dwelling apartment, be prepared for the proceedings to take up to a year.

Either way, begin serving her with the eviction notices immediately, The sooner you start the better. You may need to hire a service that will locate her and serve her with the papers. They can act as a witness to the serving process. That way, your tenant cannot claim that she never received notice in court.
Make sure you have a paper trail and make sure that you follow the letter of the law exactly. Do not just wing it. So do your homework on your particular situation and use your head.
Good luck.

Remember its your house and she is really only just staying in it like a hotel. if she refuses after a court notice then she will be taken out of the house by police officers
