A seller's power of attorney (POA) holder mistakenly included an extra survey number in a sale deed. While the POA holder agrees to rectify the deed, the original power issuer is refusing to provide a 'living certificate'. The core issue is whether this certificate is necessary for the rectification, especially since the POA is still valid and the holder is willing to sign. Advice suggests consulting a lawyer and exploring alternatives like a notarised affidavit from the POA holder confirming the principal is alive, which may satisfy the Sub-Registrar's requirement.
