Quick answer

What this page answers

Korea's separate-property default with a contribution claim means an agreement is addressing a different baseline than clients expect.

The specific situation

The facts this usually involves

A couple plans to marry; one holds Korean property and business interests, and both will spend time in China.

The first thing to do

Where to start in practice

Address the contribution claim explicitly, and state the governing law where enforcement is most likely to be needed.

The position in one paragraph

Korea's separate-property default with a contribution claim means an agreement is addressing a different baseline than clients expect.

Because Korean law starts from separate property and allows a claim for contribution to marital assets, the default is already protective of premarital assets. An agreement therefore needs to address the contribution claim specifically, rather than simply declaring assets separate.

A typical situation

A couple plans to marry; one holds Korean property and business interests, and both will spend time in China.

Drafting an agreement that declares assets separate without addressing the contribution claim. The declaration then does not achieve what it appears to.

What distinguishes this from a purely domestic case

Korean law recognises a separate-property principle with a claim for contribution to marital assets, which differs materially from the Chinese position.

On the China side, the connecting factor has to be established on the documents: A prenuptial or postnuptial agreement is enforceable in China where it complies with the formal requirements and is not used to evade obligations.

The practical sequence in a South Korea-connected matter

Decide which law should govern the agreement, given where the assets and the parties are
Identify the assets each party brings in and those acquired during the marriage
Consider whether a trust or corporate structure is appropriate, and who controls it
Record the agreement in a form that will actually be recognised in each relevant jurisdiction

Certain Korean documents require a prior certification before the Apostille is issued, which adds a step that is easy to miss.

How South Korea documents are handled

Apostille from the Korean Ministry of Foreign Affairs; certain documents require a prior certification by another authority.

The family relations register (ga-jok gwan-gye deung-rok bu) matters more than the marriage report, and it must be a recent certified extract.

The family relations register is a live record of status, so an old copy is not accepted.

What has to be decided before filing

Address the contribution claim explicitly, and state the governing law where enforcement is most likely to be needed.

The boundary to plan around is this: An agreement that is valid in one country may not be recognised in another; the governing law and the enforcement jurisdiction both matter. Where value sits in South Korea — typically real estate, jeonse deposit funds, small business interests — it is handled by agreement or by a separate route there, not by an order the Chinese court could enforce directly.

If your situation has a South Korea element

Planning is far cheaper than litigating, particularly where assets are held in more than one country. Tell us where the assets are and we will outline what is worth structuring now.

Frequently asked questions

Is a prenuptial agreement enforceable in Korea?

It is recognised, subject to requirements including fairness and proper disclosure.

Does it need to be registered?

Requirements vary, and it should be checked rather than assumed.

Which law should govern?

The law where enforcement is most likely to be needed — usually where the assets are.

Which South Korea document should be dealt with first?

The family relations register is a live record of status, so an old copy is not accepted. In practice the document that takes longest to obtain should be started first, not the one that is easiest to list.

Do you accept a matter with no connection to China?

No. The team only acts where the matter has a connection to China — a party's Chinese nationality, domicile or habitual residence, a marriage registered in China, or property, accounts, equity or evidence located in China. Purely foreign disputes are not accepted.

Do you accept a matter with no China connection?

No. We only act where the matter has a China connection: a party in China or holding Chinese nationality, domicile, habitual residence or identity documents, or property, a company interest, evidence, a document or an enforcement step located in or directed at China. Where everything — the parties, the assets and the documents — sits outside China and no Chinese court or authority needs to act, a lawyer in that jurisdiction is better placed to help and we would not be the right firm.
