Hold Harmless Agreement

[Sarimar Hernandez]

A buyer is offering to buy a triplex that has a lien and code violations and take over all the issues. The seller is willing to accept a low offer to an investor that takes over all these issues with the city. What form needs to be signed to release the seller from the responsibility and have the new owner deal with the violations and lien? I heard a Hold Harmless Agreement is what is needed. Where do I find that? Thank you!
