I had a mortgage with my father, who passed away last year. There was no promissory note and no lien, and the company managing the debt went out of business 2 years before he died (LoanKin). The original loan amout was $228k, of which I had paid off $244k over 17 years. I had $138k remaining on the loan, which I was continuing to make payments on, per a gentlemen's agreement. Question: does that debt have any value after his passing? Do I owe any of that balance to his estate? Again, there is no documentation of any kind on the loan - only my own recollection, and an email I wrote to my siblings disclosing the debt. The estate lawyer is aware of the debt and its original terms, but various sibs disagree on its valuation. Help?
