Legal Question in Real Estate Law in Maryland

The mortgage is a lien against the property. If not paid, the lender has a right to foreclose and auction off the property. If you do not want that to happen the mortgage will need to be paid.

You mention that no will existed --- assuming your parents owned the property jointly as tenants by the entirety and that the second parent to die was not remarried, the property will usually get divided in equal shares among any children. Someone would need to open up an estate in the county where that parent lived and go through the process of probating the estate to formally transfer the assets.

I encourage you to have an attorney review the particulars of your case, including any deed, to help you with the next steps. While the above post does not substitute for legal advice I hope that it helps.
