Indemnity for struck-off companies secures claimants against post-strike-off liabilities and requires authorised government bond and official undertaking. Form STK-3A is an indemnity bond by an authorised representative of the administrative Ministry/Department, undertaking to indemnify claimants and any persons for lawful claims, losses, and previously unknown liabilities that may arise after a company's name is struck off the register, pursuant to section 248; the bond must be on appropriate stamp paper, signed and sealed, and accompanied by the Ministry/Department's authorisation.
