Taxing Matters
Absent a lease with the parent for a set period of time the parent is free to end the tenancy at any time with appropriate notice to the child. If the child does not get out in that notice period, the parent may begin formal eviction proceedings to get the child out and will likely succeed since, absent a lease for a set period of time, the parent does not need a reason to terminate the tenancy.
All the issues you raise of the parent being violent, stealing from the child, destroying the child’s property, etc., may give rise to other legal claims against the parent but will not provide any protection against the eviction.
