My neighbour took my signature as a witness. I did not read the form but remember that franking was done on the form. It was not signed otherwise, nor any details written in the blanks given in the form. He was in a hurry so I put my initials, name and address as the first witness. Second witness had already signed. No dates were written. He said that it is an affidavit for transfer of physical shares from his Late mothers who is second holder and he being the first holder. Later being worried I had given my initials on a blank form as a witness I got worried and asked him to show the signatories of the document and I do not need to see the content otherwise. But neighbour is postponing and not showing me that form. What recourse do I have to avoid some bigger problem in future if my neighbour is doing any fraud or helping some one else do fraud? Kindly advise.
