last week I visited nearby branch of BoM (my dad's pension account is with Bank of Maharashtra). They sent a person to my place for verification. The nearby branch completed necessary verification and signed the LC form. The branch manager then sent a scanned copy of signed LC form to the branch holding my dad's pension account. That was swift too.
Before going for this step, I had contacted various centers authorized for carrying out LC verification. The list of such centers in your area can be easily found on Jeevan Praman website (
