JA: Where are you? It matters because laws vary by location.
Customer: The house although not in her name she thought was protected however it has recently been sold after they have been split up for 10 years. It was drawn up by lawyers and we have a copy but never signed , is it legal.
JA: What steps have you taken so far?
Customer: so far we haave written to her ex to tell him that we require him to pay half of the profits of the assett. He has written back asking for proof of date and signature for his lawyers. we have told him the information he requires is with his lawyers who drew up the document. We have conatected the lawyers and they say the documnets may now be desroyed as they only hold them for so long but they do have proof the document was done.
JA: Is there anything else the Lawyer should know before I connect you? Rest assured that they'll be able to help you.
Customer: dont think so
