De Facto Marriage Dissolution Lawyer
De Facto Marriage Dissolution Lawyer | What you can claim when an unregistered relationship ends
A de facto marriage (사실혼) is a relationship where two people live together with the intention and substance of marriage, but never completed the marriage registration required under Korean law (민법 제812조). Because there is no registered marriage, there is no "divorce" in the legal sense \u2014 instead the relationship is "dissolved" (사실혼 해소), and Korean courts have extended many divorce-related protections to this situation by analogy, including property division and consolation money for unjustified unilateral termination. Whether you qualify at all turns heavily on evidence: cohabitation records, family recognition, joint finances, and how the relationship ended.
De Facto Marriage Dissolution | What makes a relationship a "de facto marriage" in the eyes of the court
Korean law does not define de facto marriage in a single statute; it is a status recognized by case law that borrows selected effects of registered marriage under the Civil Act (민법). Courts look at substance over form, but the following elements matter most in practice.
Both partners must have genuinely intended to be husband and wife, not just dating or living together casually. Courts infer this from how the couple presented themselves to family, friends, and institutions — wedding ceremonies, joint greeting cards, or introducing each other as spouse are commonly cited evidence.
There must be an actual shared household — cohabitation, shared finances, mutual support — that objectively resembles a marriage. A relationship that never progressed beyond occasional overnight stays is unlikely to qualify even if both sides call it serious.
If one party was still legally married to someone else during the relationship, the later relationship is generally treated as an adulterous affair rather than a de facto marriage, which changes what remedies are available (민법 제810조 관련 중혼 금지 법리).
Courts distinguish between couples who simply postponed or skipped registration despite being free to marry, and couples who could never have registered (e.g., where a formal marriage was legally barred). This distinction can affect the strength of a de facto marriage claim.
What a de facto marriage is not
Casual cohabitation, a short-term relationship, or a couple still in the dating/engagement stage without shared married life generally does not meet the standard. Because there is no registration to point to, the burden of proving these elements existed falls on the person asserting the de facto marriage, which is why documentary evidence matters so much in these cases.
De Facto Marriage Dissolution | Property division, financial support, and consolation money
Once a de facto marriage is recognized, courts have applied several divorce-related remedies by analogy, even though the underlying statutes were written for registered marriages.
Division of property acquired together
Property jointly accumulated during the relationship through mutual cooperation — a home, savings, a small business — can be divided upon dissolution, applying the same underlying logic as division of marital property between registered spouses (민법 제839조의2 유추적용). Property one partner owned before the relationship began, or received solely as a personal gift or inheritance, is typically treated as separate property and excluded.
Consolation money when termination is unjustified
If one partner unilaterally and without justifiable reason ends the relationship, or is otherwise responsible for its breakdown (through infidelity, violence, or abandonment), the other partner may claim consolation money for emotional distress, similar to a divorce consolation money claim. The amount depends on the length of the relationship, the reason for the breakdown, and each side's conduct.
No automatic inheritance or spousal status
A surviving de facto partner does not automatically inherit from the deceased partner the way a registered spouse would, because inheritance rights under the Civil Act are tied to registered marital status. This is one of the sharpest practical differences between a de facto marriage and a registered one, and it often surprises long-term partners who assumed they had the same rights as a legal spouse.
Children born during the relationship
A child born to an unmarried couple is legally the mother's child unless the father completes a formal acknowledgment of paternity (인지), even if both parents intended to raise the child together as a family. This affects child support claims, custody arrangements, and the child's surname and family registry entry, and is frequently a separate legal step from the dissolution itself.
De Facto Marriage Dissolution | How the relationship actually ends, and what evidence matters
Unlike a registered marriage, there is no court filing required simply to end a de facto marriage — either partner can walk away. Disputes arise when one side denies the relationship ever reached the legal standard, or disputes who is at fault for the breakdown.
Proving the relationship existed at all
Because there is no marriage certificate, the person claiming a de facto marriage typically gathers evidence such as a resident registration showing a shared address, joint bank accounts or shared household expenses, wedding photos or ceremony records, text messages, and statements from family or friends who witnessed the relationship.
Establishing fault for the breakdown
Just as with divorce, fault matters for consolation money — evidence of an affair, domestic violence, or abandonment strengthens a claim, while a mutual, no-fault separation may leave only the property division claim available.
Filing a claim if the other side disputes the relationship's status
When the other party denies that a de facto marriage ever existed — often to avoid property division or consolation money — the claimant generally needs to bring a civil lawsuit asking the court to first confirm the existence of the de facto marriage before ruling on the financial claims that flow from it.
De Facto Marriage Dissolution | From initial consultation to resolution
We review the timeline of the relationship, cohabitation records, financial documents, and any communications to assess whether the relationship is likely to meet the de facto marriage standard and to identify what evidence gaps need to be filled.
Many de facto marriage disputes can be resolved through direct negotiation between the parties or family court mediation, particularly where both sides agree the relationship existed and are disputing only the division of assets.
If the other side denies the relationship existed, or the parties cannot agree on property division or consolation money, we file the appropriate civil claim — which may include a request to confirm the existence of the de facto marriage as a preliminary matter.
The court examines documentary evidence and witness statements regarding cohabitation, shared finances, and the circumstances of the breakdown, and both sides present arguments on fault and asset valuation.
The case concludes either through a court-mediated settlement or a judgment determining whether a de facto marriage existed and, if so, how property should be divided and whether consolation money is owed.
De Facto Marriage Dissolution | How legal fees are structured
Calculated based on the complexity of proving the existence of the de facto marriage, the value of the property in dispute, and whether the case proceeds through negotiation only or requires full litigation.
If the case involves a monetary claim such as property division or consolation money, a portion of the fee may be structured as a percentage of the amount actually recovered, agreed upon in advance.
If separate issues arise — such as a paternity acknowledgment claim for a child born during the relationship, or a related criminal complaint — these are typically billed as separate matters from the core dissolution case.
Court filing fees, service of process costs, and expenses for evidence such as expert appraisal of jointly held property are billed separately from the legal fee itself.
