Children are availing expired mother's pension
Now the query is as to whether they can get maintenance from the father, who is having only the pension as a source of income.
It all depends on the age of children and other properties in the mother's name and their name and need for such maintenance.
If the father nominates any of his legal heirs, depending on such eligibility criterion, they may receive the pension of such deceased father.
If a mother's pension is sufficient for maintenance as of now, for maintenance such children may not be eligible to legal claim from the pension of living father for their maintenance.
