We were closing on our house; the buyer signed closing documents, then our Realtor told us not to go to title company, because the buyer's soon-to-be-ex-wife would not sign a document. We didn't know she existed until last Friday as she isn't on contract, HUD, etc.. . She went to title company and told them she would sign, took documents to her attorney and has decided she now wants to renegotiate their custody agreement and will not sign. We have learned she was agreeing to sign the document for 2 months, but at closing day, she changed her mind. We have now lost the buyer, we also lost prime moving season (Summer), we were getting funding from HAP (program from military to help offset loss), title company has to send back $88,000 check to HAP, we will have redo HAP qualification process (which takes 30 days) and if programs runs out of funds we won't get it again, buyer was renting and has to move out, so we will have to pay another mortgage payment. My question is, can she be held liable or is there any recourse against her for her continuing to agree verbally to everyone she would sign document and not doing so on closing day?
