My boyfriend died and the house is in his name who does the house go to?

You need to review the mortgage loan documents to see what remedies both the lender and your boyfriends heirs are entitled to upon the passing of the borrower. Additionally, you need to file to become executor of his estate, which then would give you the authority to renegotiate the terms of the loan so the heirs can assume said loan. If these attempts are not acceptable to the lender, then they may just sell the home to recover the balance remaining on the note. You need to bring all the paperwork with you including but not limited to the will, the loan agreement and a market appraisal of the home etc and speak with an estate planning lawyer for advice and representation.
