Hello, this is Cheongchul Law Firm.

"My ex isn't paying child support — do I just have to wait?" This is one of the most common questions we hear. The short answer is no. Child support is not an ordinary private debt between former spouses; it is a right tied directly to a child's survival, and Korean law therefore provides enforcement tools that exist for no other type of claim. This article sets out the measures available, in the order you would use them.

1. Why child support is treated differently from ordinary debt

With an ordinary loan, you obtain a judgment and then enforce it through attachment and collection. Child support, however, is a recurring periodic payment, so starting fresh enforcement each time an instalment is missed is impractical — the child's life continues in the meantime.

The Family Litigation Act therefore provides dedicated enforcement tools for child support — direct payment orders, security orders, enforcement orders and detention — and the Act on Enforcing and Supporting Child Support Payment adds licence suspension, publication of names, travel bans and criminal penalties. In short, holding out is not a winning strategy for the paying parent.

All of these tools require an enforceable title — a judgment, adjudication, mediation protocol or a child support agreement protocol. If you divorced by agreement, the child support agreement protocol serves that function.

2. Step 1 — Direct payment order: collecting straight from the employer

Where the paying parent fails, without justifiable reason, to make two or more periodic child support payments, the family court may issue a direct payment order on application (Article 63-2 of the Family Litigation Act).

Under that order, the paying parent's employer, as the withholding agent for income tax, deducts the support from wages and pays it directly to the custodial parent. Because payment then occurs automatically each month regardless of the payer's wishes, this is the most powerful tool where the payer is a salaried employee.

It offers three practical advantages:

1. No need to repeat attachment proceedings each time a payment is missed.

2. Future instalments are secured along with current ones.

3. Direct contact and confrontation with the other parent is reduced.

Where the payer changes jobs frequently or has irregular income, a direct payment order is less effective. In that case, applying for a security order and, if security is not provided, a lump-sum payment order covering future support may be the better route (Article 63-3).

3. Step 2 — Enforcement order and administrative fines

The family court may order a defaulting parent to perform the obligation within a set period (Article 64 of the Family Litigation Act).

What follows matters more. Failure to comply with that order without justifiable reason can result in an administrative fine of up to KRW 10 million (Article 67(1)). Simply asserting an inability to pay is rarely accepted; the court examines actual income, assets and the effort made to pay.

An enforcement order does not itself extract payment, but it is the gateway to detention, which makes it practically significant.

4. Step 3 — Detention

Where the parent, having received an enforcement order, fails to make three or more periodic payments, the family court may order detention for up to 30 days (Article 68(1)). Detention holds the defaulting parent until the obligation is performed and is a highly exceptional measure, restricting personal liberty for non-payment of money.

It matters in two ways: as direct pressure to pay, and as the precondition for the administrative and criminal sanctions discussed below. In practice, arrears are often paid at precisely this stage.

5. Step 4 — Administrative sanctions and criminal penalties

Where payment is still not made after a detention order, sanctions under the Act on Enforcing and Supporting Child Support Payment follow.

1. Request for suspension of the driving licence — the Minister of Gender Equality and Family may ask the competent authority to suspend the payer's licence, which is significant pressure where driving is tied to their livelihood.

2. Publication of names — the personal details of qualifying defaulters may be published.

3. Travel ban request — a travel ban may be requested where arrears exceed the prescribed threshold.

4. Criminal penalties — a parent who, having received a detention order, fails without justifiable reason to pay within one year may face up to one year's imprisonment or a fine of up to KRW 10 million.

The key point is that non-payment of child support now reaches beyond administrative fines into criminal liability. Simply explaining this sequence accurately to the other parent often moves negotiations forward.

6. What to check first

1. Do you have an enforceable title? Identify whether you hold a judgment, adjudication, mediation protocol or child support agreement protocol.

2. What is the payer's income structure? A direct payment order suits salaried employees; for the self-employed, asset investigation and security or lump-sum orders come first.

3. How many payments have been missed, and over what period? Two missed payments are required for a direct payment order and three for detention, so keep a dated record.

4. Preserve transfer records and messages — partial payments or transfers sent under another description are a frequent source of dispute.

5. Consider public support — the Child Support Agency can assist with collection and litigation support.

Unpaid child support is not simply a debt problem; it is a question of the child's rights. Working through the statutory enforcement steps in order is far faster than waiting.
