My father died in 2012 and my dad's long term girlfriend listed on the Death Certificate that they were married. Years later my actual siblings and I are trying to rid ourselves of one of the properties left by my father and are not able to because the title company says the Death Certificate shows he was married and he had no will. A list of heirs were filed by me and my siblings that don't include her but that isn't enough. I have reached out to her multiple times to get this situation resolved and she refuses to help. We are about to lose this home to a tax sale if I can't figure out what to do.
While more careful review is warranted, it sounds like you need to reopen the probate, get a ruling on who the heirs are, and have the appointed personal representative sign the corrective deed. It may be useful to get the sale approved by the court. Doing all of this without a lawyer will be quite difficult, but you may be able to fund the legal expenses by contracting the sale to a buyer who will guarantee the legal fees.
Reading an answer on the Internet does not create an attorney-client relationship. You are represented by me when we have both signed a retainer agreement (on paper or electronically) and some money has changed hands. Usually, you will have been asked specific questions about your situation and all potential conflicts of interest will have been resolved. Until then, you have no more right to rely on this answer than if you read it in a novel or on LegalZoom.
You state your father died in 2012. I assume he was living in DC at the time. He owned real estate. Most likely, his estate will need to be probated before any of the properties can be sold. The probate process will take care of the mischaracterization on the death certificate--assuming it was a mischaracterization.
