My uncle was my grandmothers POA. He put a lein against her home before she passed away in 2004, stating she borrowed $15,000.00 from him. He never probated the will, and stayed in her home until he passed away March 16,2013. He also took a loan against her home for $43,000.00 as POA ( before her death) and has only made interest pmts since. Nothing was ever taken out of my grandmothers name. So is the lien legal since he signed it all himself?
