1. Identify the reason
Common reasons include revised/corrigendum PPO, OROP revision, DR increase, delayed family pension, restoration of commuted pension or correction of an earlier pension error.
2. Find the effective date
Use the Government order and PPO. The issue date of an order may differ from the date financial benefit takes effect.
3. Split the period when rates change
If DR changes during the arrear period, calculate each DR period separately. Do the same if basic pension changes again.
4. Compare due and paid
For each period, calculate revised basic pension plus applicable DR and other sanctioned elements, then subtract what was already paid.
5. Check separate credits
Arrears may be credited separately from the monthly pension. Check bank statements/payment history before concluding that nothing was paid.
6. OROP arrears need the right table
Use the correct pension category, rank/equivalent, qualifying service and applicable OROP table. DESW issued corrections in October 2025 to specified OROP 2024 tables.
7. If arrears are short
Prepare a simple period-wise calculation and attach the relevant PPO/revision/order and payment statement.
8. Arrears after death
DESW has separate historical orders on payment of pension arrears where no valid nomination exists and on family-pension arrears. Legal-heir entitlement should be checked under the applicable order.
9. Processing time
There is no one universal official disposal time for every pension arrear case.
