[Direct answer]In the Beijing area, a legally valid prenuptial agreement must meet all three requirements: it must be in writing (as required by Article 1065 of the Civil Code), reflect the true intentions of both parties, and its content must not violate mandatory legal provisions or harm the interests of third parties. Entrepreneurs in particular should clarify four key points: the ownership of equity and its appreciation gains, the rules for dividing post-marital income, the separation of corporate operational debts from family debts, and the arrangements for intellectual property and future investment returns. It is recommended to simultaneously handle notarization and retain a list of assets as an attachment to avoid difficulties in providing evidence after marriage.

1. Problem background and typical scenarios

An entrepreneur's marriage is never just about two people: fluctuations in company equity, the risks of investment and financing bets, and the interconnected guarantees between upstream and downstream partners may all drag the family's assets into the vortex of business operations. Prenuptial agreements are supposed to be the primary tool for isolating property risks, but in practice, signing one is often equivalent to not signing one at all, with clauses conflicting with each other and cases of ignoring changes within the marriage being commonplace.

II. Key points of contention

First, common flaws in the effectiveness of agreements: whether oral agreements, signing on behalf of others, or signing under coercion are valid. Second, the distinction between ownership of equity and post-marital appreciation: pre-marital equity is personal property, and how to determine the appreciation generated from post-marital operations. Third, the boundaries of debt isolation clauses: whether it is possible to stipulate that all operating debts shall be borne by one party. Fourth, coordinating conflicts between the agreement and the company's articles of association and shareholders' agreements.

III. Professional analysis by Henglue Law Firm

The first layer emphasizes the necessity of solid legal grounds: According to Article 1065 of the Civil Code, the parties may stipulate in writing the ownership of property acquired during the marriage and pre-marital assets. Such agreements must be in writing and legally binding to both parties. In practice, the most common obstacles to the effectiveness of such agreements lie in procedural issues and the lack of clear intent—for example, signing without witnesses, one party coercing the other by threatening to expose private information, or agreements that are grossly unfair and lack independent property safeguards. In such cases, the risk of having the agreement overturned in litigation significantly increases. When Beijing courts adjudicate such disputes, they focus on reviewing the timestamp of the signing, the degree of disclosure of the parties' property status, and evidence of autonomous decision-making. Therefore, recording the signing process and obtaining notarization are the most cost-effective safeguards. The second layer emphasizes the need to separate equity provisions: Pre-marital equity is considered personal property, but dividends, appreciation, and capital increases acquired during the marriage are often deemed marital joint property or subject to compensation in judicial practice. The agreement should clarify three key arrangements: ownership of the equity principal, distribution ratios or waiver rules for post-marital income, and restrictions on disposal rights (e.g., requiring spousal notification for major transfers). Additionally, attention should be paid to restrictions in company bylaws and shareholder agreements to avoid conflicts between intra-marital agreements and corporate documents rendering provisions ineffective. The third layer focuses on the enforceability of debt provisions: Spouses may stipulate that their property be owned separately. According to Article 1064(3) of the Civil Code, if the parties agree that property acquired during the marriage belongs to each individually, and one party incurs debts that the creditor knows about the agreement, the debts shall be satisfied with the party's personal assets. However, if the creditor is unaware of the agreement, the stipulation cannot be invoked against bona fide third parties. Therefore, debt isolation clauses must be accompanied by notification mechanisms. When raising funds for the company, proactively disclosing intra-marital property agreements to creditors is essential to effectively isolate risks. The fourth layer emphasizes dynamic adjustment mechanisms: Entrepreneurs' assets and liabilities often fluctuate significantly during marriage. The agreement may include regular confirmation clauses (e.g., annual updates to property lists) and triggering adjustment mechanisms (e.g., supplementary confirmations after major financing events). In Beijing, courts also recommend integrating tools such as insurance and trusts with the agreement to form a comprehensive risk isolation structure for family and business assets.

IV. Practical Suggestions and Legal Basis

The first step is to complete the disclosure of both parties' assets before signing the contract, form an attachment list, and have both parties sign and confirm it. The second step is to specify the ownership certificate number and disposal rules for core assets such as equity and real estate. The third step is to have the terms drafted and reviewed by a professional lawyer to avoid conflicts with company documents. The fourth step is to handle notarization or lawyer's witnessing and keep records of the signing process. The main legal basis: Articles 1062, 1063, 1064, and 1065 of the Civil Code of the People's Republic of China (effective from January 1, 2021); the specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

Three key points of a prenuptial agreement for entrepreneurs: Written and notarized agreements are the bottom line; separate clauses for equity appreciation and debt isolation; agreements should not be enforceable against uninformed third parties; a disclosure mechanism is the true form of isolation; and clauses must align with the articles of association and shareholders' agreements to prevent agreements from becoming invalid after marriage.

VI. Frequently Asked Questions

Q1: Is a prenuptial agreement only valid if it's notarized?

No. A written agreement becomes legally binding once it is signed by both parties. Notarization is just a means to enhance the evidentiary force; however, when it comes to large-value assets such as equity and real estate, notarization can effectively reduce the risk of being questioned about coercion or forgery after the fact.

Q2: Is the increase in value of pre-marital equity considered marital property after marriage?

It is necessary to distinguish that the natural appreciation of equity itself generally belongs to personal property. The appreciation and dividends generated from active operation after marriage are often regarded as common property or require compensation to the spouse in judicial practice. It is the most secure way to handle this issue by explicitly stipulating it in a prenuptial agreement.

Q3: Is it valid for the agreement to stipulate that each party is responsible for its own debts?

The agreement is valid within the couple, but can only be used against creditors when the counterparty is aware of the agreement; if the creditor is unaware of it, he or she may still claim according to the rules on joint debts of the couple, so an external disclosure mechanism is needed to back it up.

Q4: Can a prenuptial agreement signed under duress be revoked?

Yes. If the contract is signed under duress, the party under duress may, in accordance with the provisions of the Civil Code on revocable civil legal acts, request the revocation of the contract within one year from the date of termination of the coercive act, and it is necessary to keep the evidence of coercion.

Q5: Can we still sign a property agreement after marriage?

Yes. Marital property agreements are also protected by law. Entrepreneurs can sign additional agreements at key stages such as major investments and financing, childbirth, etc. to redefine the ownership of property and debts.
