Paternity and Child Support From Abroad

The relationship was with a Korean national; the child was born after you had left, or you left together and he stayed, or he simply stopped answering once the pregnancy was known. Now you are raising a child in another country whose father is in Korea, has a Korean name on no document the child holds, and pays nothing. The question is whether anything can be done about that from where you are — and the answer is more than most parents in this position expect.

Two Korean statutes carry it: the Civil Act (민법), which lets a child whose father will not acknowledge them obtain a court declaration of paternity, and the Family Litigation Act (가사소송법), which gives Korean family courts unusually direct tools for collecting support once it is ordered. The amounts themselves are the subject of Child Support: How Amounts Are Set; this guide is about getting from abroad to an order, and from an order to money.

One honest line first: this is the from-abroad case that most needs a trip. The sections below say exactly where.

1. Can a Korean court hear it when you live abroad?

For cases about whether someone is a child’s parent, Korean courts have jurisdiction where the child’s habitual residence is in Korea, or where the child and the parent being sued include a Korean national (Act on Private International Law art. 57). A foreign mother abroad suing a Korean father in Korea therefore has a Korean forum on the second ground alone. Support and custody questions attached to the same facts generally travel with the case.

Which country’s law the court applies, and whether a judgment from your own country could instead be brought to Korea, are real questions in some cases — the broader treatment is in Which Country’s Court?. The practical point for most readers is simpler: the father, his income, and his assets are in Korea, and a Korean order is the one the Korean enforcement tools attach to.

2. Establishing paternity: acknowledgment or a court declaration

A child born outside marriage has no legal father in Korea until one is established. The simple route is acknowledgment (inji) (인지): the father registers the child as his (Civil Act art. 855), and the effect runs back to the child’s birth (art. 860). Some fathers who have gone quiet will still sign when approached through counsel with the alternative spelled out; it is worth one properly framed request.

If he will not, the child — through you as legal representative — can bring a paternity suit (inji cheonggu ui so) (인지청구의 소) and have the court declare him the father (art. 863). The declaration has the same backdated effect. If the father has died, the suit is brought against the public prosecutor instead and must be filed within 2 years of learning of the death (art. 864) — the one hard deadline in this guide, and the reason a parent who hears of a death should act on the news rather than grieve first and file later.

1. 1

   Power of attorney and the file

   Legalised where you live. With it: the child’s birth record, anything showing the relationship and its timing — messages, photographs, travel records, remittances.
2. 2

   Mediation first

   Paternity cases must go through family-court mediation before trial (Family Litigation Act art. 50). A father who attends sometimes acknowledges there; one who does not simply moves the case on.
3. 3

   Trial — and the DNA order

   Where the evidence is contested, the court orders genetic testing (art. 29). Section 3 explains what that means for you and the child.
4. 4

   Declaration and registration

   The judgment is recorded in the Korean family register; the child now has a legal father in Korea, and the support claim in section 4 opens.

3. The DNA test — and why it needs a trip

Where other evidence does not settle the question, the family court may order the parties to undergo genetic testing, within limits that protect health and dignity (Family Litigation Act art. 29). The order has teeth: a party who defies it without good reason faces a fine of up to ₩10 million, and one who defies it again after being fined can be detained for up to 30 days until they comply (art. 67). A father who thinks silence will protect him usually learns otherwise at this stage.

The part that matters for a parent abroad: court-ordered testing is taken by an examiner the court appoints, with identity checks, and in practice that sampling is done in Korea. A kit mailed from overseas is not what the court orders. The child, and often you, will need to be in Korea for the sample — which is why the sensible plan is one trip timed to the test, with any hearing the court wants you at scheduled around it.

The court’s test, not yours: a result from an examiner the court appointed is what the judgment rests on, and it is taken in Korea.

4. Child support: the order, and the tools behind it

Once paternity is established, the father owes support like any parent, and the court sets a monthly amount by reference to both parents’ incomes and the child’s age — the mechanics and typical figures are in the child-support guide linked above. Whether support can be claimed for the period before the order is fact-specific; raise it from the start rather than assuming either way.

What distinguishes Korea is what happens when the order is ignored. After 2 missed payments, the court can order the father’s employer to deduct the support from his wages and pay it to you directly — an order with the force of a seizure and assignment combined, and one that reaches future instalments as they fall due (Family Litigation Act art. 63-2). The court can also require security for the support, and where it is not provided, order some or all of it paid as a lump sum (art. 63-3). A performance order (art. 64) backed by fines of up to ₩10 million (art. 67) sits behind both.

Beyond the court, the child-support enforcement framework adds administrative pressure on serious defaulters — exit bans, driver’s-licence suspension and name publication for those who ignore a performance order across multiple payments or a large arrears figure — and a public agency, the Child Support Agency (Yangyukbi Ihaeng Gwalliwon) (양육비이행관리원), that supports custodial parents of children under 19 with claims and collection. Whether a custodial parent living abroad qualifies for its help is not something to assume; ask early. What does not exist is a simplified cross-border collection channel under the Hague child-support regime, which Korea is outside — so enforcement in practice means enforcement in Korea, against Korean income and assets.

5. What can be done from abroad — and what needs you in Korea

6. Common mistakes

• Waiting for him to come round. Years pass, evidence fades, and if he dies the 2-year clock starts without you noticing. File while the facts are fresh.
• Sending a home DNA kit and expecting the court to use it.A private result may persuade him; it is not the court’s test and does not replace it.
• Letting the relationship record disappear. Messages, photographs with dates, hospital records, transfers — exported now, before an old phone or account is gone.
• Booking a short trip with no slack. The sampling and any hearing the court wants you at should fall inside one visit; build in days, not hours.
• Stopping at the declaration. Paternity is the door; support and its enforcement orders are the room. Apply for them in the same breath.

Start with two things you can do from your kitchen table: assemble the relationship record, and begin the power of attorney. The trip comes later, and it comes once.
