If you allow her to live there for long enough she can indeed claim ownership of the property under adverse possession laws. Make her sign a lease that says she will pay rent or perform some service of value in exchange for her continued use of the address. And get her daughter’s belongings out ASAP.
IF she gives you problems tell her you will turn her into the police for insurance fraud.
Adverse possession has to be for a long time. I also think it has to be exclusive.
Consultation with a lawyer is indicated.
That is the worst advice I have ever read.
OFR needs to get this family out of their life, house, everything and do it by the law
No more continuing for her to use the address. That stops immediately.
Completely wrong. If you “allow” someone to use property, it is not adverse. There may be a tenancy created which would require eviction. But permissive use is an absolute defense to adverse possession. Among other things, AP must be hostile and exclusive.
"Hostile" is a necessary requirement under adverse possession. Invitation by employment extinguishes that requirement.
