Hi, thanks for your help everybody, adverse possession is exactly the thing I was thinking of. I already advised my aunt to get the house signed over to her name, which is now in process. I told her that she can then leave to house to the local hospice, should she so choose! I know that this is deeply upsetting for her, and want the bullying to stop so that she can live out her days in her own house in peace. Thanks again, everybody.
