We did not have an insurance policy per se. It was a Bank Guarantee. On it , it had the names of me and my husband, our passport numbers, the amount of money covered and the precise property that we were buying + relevant dates. We took the original document from the ( c**p) Lawyer when we discovered there were problems. We also changed Lawyers..twice. (3 in total)
If you are instructing new Lawyers to act for you, they wil need the original document.
