Full arrears are payable on foot of late claims for the old age contributory pension, retirement pension and widow(er)'s contributory pension in the case of claims which are not more than 12 months late. Additional arrears are payable on a proportional basis in the case of claims which are delayed beyond 12 months. Further payment of pension may be made, up to the level of full retrospection, where the delay was due to incorrect information given by the Department, where illness or a force majeure prevented a person from claiming earlier or where the person is suffering current financial hardship.
