If your mom has very little furniture, then I suggest she stays until she gets evicted. Make the lender do some work to get the property back. After all, your mom is the innocent party here.
At trip down to the County Recorder’s office will give you the information that you want. You cannot get that info online or on the phone.
There are paid services that will provide you the information but since this is a one time deal, then I suggest your visit the County Recorder’s office. If anything, it’s an educational experience that will teach you about property law and the concept of constructive notice trough recordation.
