No, it is not legal to transact in a deceased person's Jainam account. If a transaction occurs in the deceased's account after the date of death mentioned in the death certificate, the transmission process will be delayed due to increased scrutiny by the Jainam team. The nominee/claimant/legal heir will have to provide the required documents as asked by Jainam's team.

However, the nominees or legal heirs of the account holder will be entitled to the funds and securities in the deceased's trading and demat accounts, respectively. They can transfer the securities and funds to their demat and bank accounts after submitting the required documents.
