My mom's elder sister also a widow. So she has also the right of the pension. My mother applied the widow pension in 2017 and my mother's file wentto the Finalcial department, but the file came back saying that the mother's sister signed the affidebit copy. My mother's sister is not willing to give the copya nd she is not willing to help in any way. My mother can not afford this pension alone. So either of the two people should apply together or else the two will have no objection letter. But mom's sister does not help us in any way. Now that's what I want to get a pension.
It means that your mother and her elder sister, both are widow at present. But then who was drawing pension earlier? I can understand that none of the two is drawing pension at present, then you have to convince your mother's sister to give NOC favoring your mother for pension. Otherwise none of you will be benefitted by querlling.
