A user is concerned about the validity of a Power of Attorney document registered in 1957. Although the Sub-Registrar personally visited the ailing wife's home and verified the document with witnesses, there is no corresponding entry in the fingerprint register. The user seeks to know if this omission can be used to claim fraud and if any time limitations apply. Replies suggest the registrar's personal visit and notes indicating the executant was 'personally known' lend authenticity to the document, despite the missing fingerprint record.
