She is a tenant at sufferance.
A tenant at sufferance is someone who has no right to occupy the premises, but is tolerated by the owner and may be terminated at the will of the owner.
A tenant at sufferance has few rights, but one of these rights is to be evicted. So in other words, one cannot simply lock her out of the home. She must be evicted like a tenant who has not paid rent. If after the quick eviction hearing she still does not leave, then, one can get a Writ and have the authorities forcibly relocate her.
However, many tenants at sufferance simply LEAVE once they are given notice that they will be evicted if they do not, since they have really no defense to an eviction.
So here, you may:
1) Give her notice to leave and if she does not;
2) Evict her as though you would a tenant; and
3) Have the authorities remove her by force if she still does not leave; and
4) Change the locks.
Again, the majority of tenants at sufferance shall leave upon notice, or shortly after an eviction is filed.
Now, for the notice, no notice is required for a tenant at sufferance unless she has lived there for over a year. If she has lived there for over a year, then a notice of 60 days is required prior to filing. The notice IS A LETTER, and I can provide a sample letter if you want.
The actual eviction begins with a petition. See HERE for the form(s) for the petition.
