Yes, prenuptial agreements are generally enforceable in China. Article 1065 of the PRC Civil Code allows spouses and intending spouses to agree in writing how property acquired before and during the marriage will be owned, and a valid agreement binds both of them. To be enforceable, the agreement must be in writing, signed voluntarily and not contrary to mandatory law — and it cannot override the court's duty to protect children's interests.
Many couples, especially international ones, assume prenups are "an American thing" that Chinese courts will ignore. That is not the case. The real question is not whether a prenuptial agreement can be enforced in China, but whether yours is drafted in a way a Chinese court will accept. This guide explains the rules as of 2026.
The legal basis for prenuptial agreements in China
China's default marital property regime is community property: most income and assets acquired during the marriage belong to both spouses jointly (Civil Code Art. 1062), while pre-marital property and certain personal items stay separate (Art. 1063). Article 1065 lets couples opt out of this default, in whole or in part. They may agree that property is:
- owned separately by each spouse;
- owned jointly; or
- partly separate and partly joint.
The agreement can be signed before the wedding (a prenuptial agreement) or at any time during the marriage (often called a marital property agreement). Both are treated under the same article.
When is a prenuptial agreement enforceable in China?
Courts typically look at four things:
| Requirement | What it means in practice |
|---|---|
| Written form | Oral promises are very hard to prove. The agreement should be signed and dated by both parties. |
| Genuine consent | No fraud, coercion or serious misunderstanding. Evidence that both had time to review — and ideally independent advice — helps. |
| Legal capacity | Both parties must be adults with full civil capacity when signing. |
| Lawful content | The agreement cannot breach mandatory law, public order or good morals, or harm third parties' rights. |
Is notarisation required?
No. A prenup does not need to be notarised to be valid in China. Notarisation is nevertheless helpful: it creates strong evidence of identity, signature and voluntary signing, which makes later challenges much harder. For international couples, a notarised version can also make the agreement easier to use in other countries.
Does property registration need to match?
It should. If the agreement says a Shenzhen flat belongs solely to one spouse but the real estate certificate lists both names, disputes and third-party problems can follow. Update registrations to match the agreement where possible. As for debts, a spouse can generally rely on a separate-property agreement against a creditor only if the creditor knew about it.
What a prenuptial agreement cannot do
Some matters are outside what spouses can decide in advance:
- Child custody — the court decides according to the child's best interests at the time of divorce, whatever the agreement says.
- Child support — parents cannot waive a child's right to support. A clause saying "no child support will be paid" will not bind the court.
- Personal freedoms — clauses restricting the right to divorce, or imposing penalties for filing, are generally unenforceable.
- Evading debts — agreements designed to shield assets from existing creditors can be challenged.
Loyalty clauses and "property on infidelity"
Some couples include clauses promising property to the innocent spouse if the other is unfaithful. SPC Interpretation II on Marriage & Family (effective 1 February 2025) clarifies in general terms how courts treat property promised to a spouse in a marriage or loyalty agreement. Practice here is nuanced: courts may treat such promises differently from ordinary property arrangements, particularly where a promised gift has not been transferred. Draft these clauses carefully and do not rely on them as your only protection.
Prenuptial agreements for international couples
Mixed-nationality couples face extra questions, and this is where a well-drafted agreement pays for itself.
Choice of law
Under China's Law on Choice of Law for Foreign-Related Civil Relations (Art. 24), spouses in a foreign-related marriage may choose the law governing their marital property — generally the law of either spouse's habitual residence or nationality, or the place where major property is located. A clear choice-of-law clause reduces uncertainty if the marriage later ends in a different country.
Bilingual drafting
A Chinese court works from the Chinese text. If the agreement exists only in English, a translation will be needed and disputes over wording can arise. We recommend a bilingual agreement stating which version prevails, with both parties confirming they understood it.
Recognition abroad
A Chinese prenup is not automatically enforceable in every other country. If you may live elsewhere, check whether the agreement will also satisfy that country's formal requirements, such as independent legal advice or financial disclosure.
Practical drafting tips
- Sign well before the wedding, not the night before.
- Attach a schedule of each party's significant assets and debts.
- Deal with future income, business interests and inheritances expressly.
- Address how the family home will be treated, including parental contributions.
- Keep evidence that each party had time and, ideally, separate advice.
- Review the agreement after major life events such as children or a move abroad.
If the marriage does end, the agreement feeds straight into how property is divided in a Chinese divorce.
Can a prenuptial agreement be challenged later?
Yes, and knowing how helps you draft one that holds up. The most common challenges are:
- Coercion or fraud — for example, one party was pressured to sign on the wedding day, or the other hid major assets. Courts can revoke terms obtained this way.
- Unclear wording — vague phrases such as "each keeps their own things" invite argument over flats, shares and savings.
- Inconsistent conduct — if the couple ignored the agreement for years and mixed their finances completely, proving which assets fall under which clause becomes difficult.
- Unlawful terms — clauses on custody, child support or restricting divorce are disregarded, although the rest of the agreement may survive.
A clear, bilingual agreement with an asset schedule, signed well in advance and ideally notarised, is much harder to attack.
Key takeaways
- Prenuptial and marital property agreements are recognised under Civil Code Art. 1065.
- They must be in writing, voluntary and lawful; notarisation is optional but helpful.
- They cannot decide custody or waive child support.
- International couples should include a choice-of-law clause and use bilingual drafting.
- Keep property registrations consistent with the agreement.
