Korea’s National Pension has time limits too. A right to benefit that is left unclaimed can lapse. The Act sets three periods: 3 years for the Service’s right to collect contributions, 5 years for the right to receive benefits, and 10 years for the right to a lump-sum refund. We read Article 115 of the National Pension Act in the original.
1. Three periods. 3 years to collect; 5 years to receive benefits, to recover overpaid contributions, and to recover wrongly paid benefit; 10 years for the lump-sum refund under Article 77(1)1 (Article 115(1)).
2. Time does not run during a suspension. While payment of the whole benefit is suspended, prescription does not run ((2)).
3. A claim interrupts it. A claim for payment of benefit or for a refund of overpayment interrupts prescription ((3)).
The three periods — Article 115(1)
| Right | Whose | Period |
|---|---|---|
| To collect contributions and other charges | The collecting side | 3 years |
| To receive benefits (other than the refund below) | The person entitled | 5 years |
| To recover overpaid amounts | The person entitled or the insured person | 5 years |
| To recover wrongly paid benefit | The collecting side | 5 years |
| To be paid the lump-sum refund under Article 77(1)1 | A former insured person | 10 years |
The text says each right is extinguished by prescription if not exercised. The direction is notable: the right to collect (3 years) is shorter than the right to receive (5 years). And only item 1 of Article 77(1) is set apart at 10 years, so we read refunds under the other items as “benefits” at 5 years (our reading). Which item covers which case is in lump-sum refund.
When time stops or restarts — paragraphs (2) to (5)
- During suspension — the right to be paid benefit does not prescribe while payment of the whole benefit is suspended ((2)).
- Interruption — notice of payment due, a demand, and a claim for payment of benefit or refund of overpayment interrupt prescription ((3)).
- Restart — interrupted prescription runs anew from the end of the payment period under the notice or demand ((4)).
- Postal time — days taken to deliver the documents are not counted in the period for claiming benefit or a refund ((5)).
Note the word “whole”: a partial suspension is not in that sentence. The grounds for suspension are in reporting duties and suspension.
Alongside the “5 years” we met earlier
Among deadlines we read in other provisions, the same number appears.
| What | Limit | Where |
|---|---|---|
| Claim for a deceased pensioner’s unpaid benefit | Within 5 years of the death (Article 55) | payment day and unpaid benefits |
| The right to benefits generally | 5 years (Article 115(1)) | This article |
| Lump-sum refund (Article 77(1)1) | 10 years (Article 115(1)) | lump-sum refund |
Setting the three side by side is our own arrangement. Whether, for a monthly pension, the “5 years” attaches to the right as a whole or to each month’s payment cannot be settled from the sentence alone, and we did not check — if you have benefit long unclaimed, confirm your own case with the National Pension Service (1355 in Korea).
From the payer’s side — 3 years and 5 years
- The right to collect overdue contributions lasts 3 years. But notices and demands interrupt it, so the 3 years do not simply run out while notices keep arriving (our reading of (3) and (4)).
- The right to get back contributions overpaid lasts 5 years.
- The Service’s right to recover wrongly paid benefit is also 5 years — the grounds are in reporting duties and suspension.
Checklist
- ☐ Any benefit you became entitled to and have not claimed (5 years)?
- ☐ A lump-sum refund never collected after leaving the scheme (10 years)?
- ☐ After a family death, the claim for unpaid benefit (5 years from the death)
- ☐ Any contributions overpaid (5 years)?
Questions that remain
Once I claim, is prescription no longer a worry?
Article 115(3) says a claim for payment of benefit interrupts prescription. On when it runs again, paragraph (4) speaks only of notices and demands, so the case of a benefit claim could not be read from this provision.
How do I find out whether money is waiting?
The National Pension Service (1355 in Korea) can check from your record. Ways to find dormant money elsewhere are collected in finding government refunds.
