Purchase agreement - contract
I was hoping someone could help. My parents sold a home in 2000 by which the buyer assumed a mortgage and issued a promissory note for $9000 to my parents. The terms of the note was that when they sold the home they would repay the note plus any accrued interest. Last year the buyer carrying the note sold the home but did not pay the $9000 plus interest as agreed. Title changed over to the new buyer with no reflection of the note that was attached to the property. Somehow the note was not repaid from proceeds of the sale. What recourses are there? Is this a case against the title insurance carrier or is this now a civil claim against the original buyer who made a substantial profit but did not repay the note. Please help.
