Ask a landlord-tenant lawyer and get answers ASAP
To get her off the lease need landlord consent. If landlord wont consent then need to file in court to get a court order. Court may release her where it is impossible for her to occupy due to abuse rendering the tenancy void. That should be explained to landlord who should accomodate and release her, not wanting to be named in a lawsuit and having to incur fees and time. It can help having a local lawyer speak to landlord about this and get that cooperation.
Let me know if that is clear, and kindly rate me positively - can still follow up too.
waiting for your reply, thanks.
