Is the Ningbo clean-out agreement valid?

"If I ever cheat again, I’ll leave with nothing"—many couples sign agreements like this. At the time of divorce, do such agreements have legal effect? How will the courts determine their validity? In a nutshell: Agreements between spouses stipulating that one party “leaves with nothing” may be deemed invalid or partially invalid by the courts if they restrict personal rights or create a manifestly unfair imbalance. However, if the agreement is formalized as a written marital property agreement clearly specifying the allocation of assets and the consequences of breach, and does not violate any mandatory provisions of the law, it may be upheld. By recharacterizing a “loyalty agreement” as a “property agreement,” its legal validity and stability are significantly enhanced.

1. Legal basis: property agreements, freedom of marriage, and validity of actions.

Article 1065 of the Civil Code stipulates: Both men and women may agree that the property acquired during the marriage relationship and the pre-marital property shall be owned by themselves, jointly or partially owned by themselves or partially jointly owned by themselves; the agreement shall be in written form, and if there is no agreement or the agreement is unclear, the provisions of Articles 1062 and 1063 of this Law shall apply; the agreement of husband and wife on the property acquired during the marriage relationship and the pre-marital property, it is legally binding on both parties. This is the most solid legal basis for a “clean break” agreement—so long as it is formalized as a written property agreement, the allocation of property within the scope of the agreement is binding on both parties.

At the same time, we should see two restrictive norms: the first is that Article 1042 of the Civil Code prohibits arranged marriage, buying and selling marriage and other acts that interfere with the freedom of marriage, and Article 1041 establishes the principle of freedom of marriage-the clauses that restrict the freedom of divorce under the conditions of "no divorce" and "divorce leads to a clean family" may be invalid due to restrictions on personal rights; second, Article 143 of the Civil Code stipulates that the validity of a civil legal act must have three elements: the actor has the corresponding capacity for civil conduct, the expression of meaning is true, does not violate the mandatory provisions of laws and administrative regulations, and does not violate public order and good customs. Pure “loyalty agreements” that tie personal relationships to the condition of “divorce upon infidelity resulting in forfeiture of all assets” have generated inconsistent judicial outcomes across jurisdictions, as they use property-based penalties to restrict marital freedom and are intertwined with issues of personal ethics.

2. Key points: two types of agreements, five criteria

1. The validity of loyalty agreements is subject to debate. Loyalty agreements stipulating that “infidelity results in the forfeiture of all marital property” are subject to inconsistent judicial treatment across different regions: some courts respect the parties’ autonomy of will and enforce the agreement as written, others deem such agreements invalid on the grounds that they condition divorce rights, while still others adjust the division of property based on principles of fairness. To date, no uniform judicial interpretation has been established.
2. Property agreements in written form are more likely to be upheld. Clearly stipulating the allocation of property in a marital property agreement (pursuant to Article 1,065) and designating “infidelity” as a trigger for modifying such allocation is more likely to be recognized than a mere fidelity agreement—because a property agreement governs property relations and does not directly interfere with personal freedom.
3. No restriction of personal rights shall be permitted. Clauses that unduly restrict the freedom to divorce, the right of access, the right to remarry, or personal liberty are invalid. With respect to provisions concerning the allocation of child custody, courts will also re‑examine such provisions from the perspective of what is in the best interests of the minor child, and may not use a property agreement to preclude judicial review of custody disputes.
4. Obvious imbalances may be adjusted. Even if the agreement is valid, if it results in one party being deprived of basic livelihood security or causes a severe imbalance in the distribution of property, the court may, in accordance with the principle of fairness, adjust the division ratio or declare certain provisions invalid.
5. Written form is the prerequisite. Verbal agreements are difficult to prove; therefore, they should be put in writing and signed for confirmation. Notarization can strengthen the evidentiary force, and notarized documents carry greater probative value in litigation.

3. Scenario breakdown: which writing styles are effective, and which are risky.

Split according to the writing method: only write the general expression of "leaving the house after cheating", the court is difficult to enforce if the property scope and attribution conditions are lacking-the direction of "leaving the house after cheating" is unclear, and it is impossible to determine which property has been disposed of; it states that "if one party cheated, a certain property and a certain account deposit under the name of both parties belong to the individual without fault", the specific property and conditions are clear, effectiveness is more favorable. Split according to conditions: those who are suspected of restricting the freedom of divorce and tend to be invalid if they are conditioned on "filing for divorce and leaving the house clean after X years of separation"; those who are conditioned on "derailment, domestic violence and other fault behaviors" and point to the wrong party's punishment, which is consistent with the principle of loyalty and fault, are relatively easier to support. Split according to the time of signing: the "loyalty agreement" signed before marriage and the marital property agreement signed during marriage have the same validity judgment rules, but the prenuptial agreement must pay more attention not to violate public order and good customs; The property division clause confirmed in the divorce agreement cannot be unilaterally repented in principle once the registered divorce takes effect, but if there is fraud, coercion or obvious unfairness, it can be revoked within one year (Article 1

51of the Civil Code, etc.).

4. Operational steps

1. Clarify the nature of the agreement: whether you intend to make marital property agreement or simply express loyalty commitment -- it is suggested to draft according to the property agreement.
2. Use a written form that clearly specifies the scope of the property, the conditions for ownership, the triggering events, and the consequences of breach, thereby avoiding vague or general statements.
3. Delete the clauses that restrict personal rights such as divorce freedom, visitation right and remarriage right to prevent the whole agreement from being deemed invalid.
4. When necessary, notarization may be carried out to enhance the evidentiary force; for agreements involving significant assets (real estate, equity interests), notarization is recommended.
5. Keep the evidence of the other party's breach of contract (chat records, alarm records, effective documents of the court, fault identification materials), and claim together with the agreement and evidence when divorcing.

5. A comparison of the validity of loyalty agreements and marital property agreements.

The difference in the effectiveness of the two types of documents determines the drafting direction. The loyalty agreement takes the "duty of loyalty" as the object, and stipulates that "derailment will leave the house clean" and "compensation will be XX million if it is committed again". Its effectiveness depends on whether it infringes personal freedom and is obviously unfair-the clauses restricting the freedom of divorce, remarriage and visitation rights are invalid, the high "derailment compensation" may be lowered or not supported due to lack of actual loss basis, and the standards of judges vary from place to different places. The property agreement between husband and wife takes "property ownership" as the subject. According to Article 1065 of the Civil Code, the pre-marital and marital property is agreed to be owned by each, jointly owned or partially owned by each. As long as the written form, meaning is true and does not harm the interests of the third party, the court usually deals with it according to the agreement-transforming the "clean body and leaving the house" into a property agreement, which is essentially to transform the identity ethics issue into a property disposition issue, the space for judicial intervention is smaller. The safe formula drafted is: specify the scope of property (specific to the location of the property, account) + attribution conditions (triggered by the fault act determined by the court or confirmed by both parties) + change arrangements (transfer or change registration within a few days after the trigger) + breach of contract relief (not to cooperate with the transfer of the liability for breach of contract). In conjunction with this, the “commitment to emotional fidelity” should be set forth on a separate page, distinct from the property agreement; even if the commitment clause is deemed invalid, it will not affect the overall validity of the property agreement.

6. The role of notarization and the timing of signing

Notarization can not give invalid terms effect, but it can significantly enhance the evidentiary power and probative power: the notary's verification records of the signatory's identity, meaning expression and terms can exclude common defenses such as "being coerced, being cheated, illiterate and mistakenly signed"; after the agreement involving real estate, equity and other major properties is notarized, it is easier for the registration agency to approve when handling the transfer. The choice of the timing of the signing is equally important: the agreement signed during the period of emotional stability, the meaning of the authenticity of the dispute is the least, in the derailment exposure, fierce conflict "forced to sign" the agreement, after the event may be requested to take advantage of the danger, obviously unfair reasons, the court will focus on the review of the signing background. Operational Suggestions: The property agreement can be signed at any time during the marriage, but the earlier it is signed and the more peaceful it is signed, the more stable the effect will be. Notarization shall be handled together with large amount of property; After signing, the real estate transfer or ownership registration shall be completed in time according to the agreement, and the "agreed right" shall be implemented as "registered right" to prevent the other party from going back on its word and not cooperating after divorce.

Examples of 7. key property conventions

Translating abstract provisions into specific assets is a prerequisite for the enforceability of the agreement. The property may be described as follows: “Both parties confirm that the house located at No. XX, XX Road, XX District, XX City (Real Estate Ownership Certificate No. XX) is marital joint property.” If one party has an act of derailment or domestic violence determined by the effective legal document or confirmed in writing by both parties, the house shall be owned by the individual of the non-fault party, and the fault party shall cooperate with the transfer registration within 30 days from the date of the determination of the act, and shall pay liquidated damages at the rate of five ten thousandths of the assessed value of the house every day. “Deposits and wealth management products may be stipulated as follows: Each party’s bank accounts, wealth management products, and fund shares shall be owned by that party respectively; if one party commits the aforementioned wrongful act, the balance in its XX account (account number XX) and the shareholding in the XX wealth management product (product code XX) shall belong to the non‑faulting party.” “Equity provision: If either party commits any of the aforementioned wrongful acts, the XX% equity interest it holds in XX Company (Unified Social Credit Code: XX) shall vest in the non‑defaulting party, and the defaulting party shall cooperate in effecting the corresponding industrial and commercial registration change.” The insurance policy may stipulate: “Both parties shall each insure the other under XX policy (policy number XX), with the beneficiaries to be changed to the children upon divorce; in the event of a fault, the cash value of the policy shall belong to the non-faulting party.” "The common denominator of the sample clauses is: property-specific, fault-verifiable, obligation-fulfilling, and a price for breach of contract-check your agreement against these four criteria, and make up for what is missing.

8. Frequently Asked Questions

Myth 1: If a “no-property” agreement is signed, the court will definitely rule in accordance with the agreement.

Error. The validity of loyalty agreements is subject to debate and may be deemed invalid or partially invalid, with adjustments made based on the principle of fairness; only when such agreements are formalized as a written property agreement that clearly specifies the scope of assets are they likely to be upheld.

Myth 2: As long as the other party commits adultery, they can be forced to leave with nothing.

Error. Infidelity must be substantiated by evidence (such as chat records, police reports, or findings in a final court judgment), and the court will comprehensively consider the principles of fairness and basic living security; it may not necessarily grant a “clean break” in which one party forfeits all assets.

Misunderstanding 3: Oral agreement is also valid

Error. Involving significant property disposition should be in written form, oral agreement is difficult to prove, basically can not get support.

Misconception 4: A clause in the agreement stating “If either party commits adultery again, they shall forfeit custody of the child” is valid.

Error. The determination of custody shall be based on the principle of acting in the best interests of the minor child; the court will conduct a re‑examination, and such provisions do not automatically bind the court.

The agreement says "1 million compensation for further derailment", will the court give a full verdict?

Not necessarily. For property payments conditional on fault, the court will examine whether the amount is commensurate with the actual damage and the income of both parties, and the obviously abnormally high amount may be lowered.

Is there a difference between a fidelity agreement signed before marriage and one signed during marriage?

The judgment rules are consistent, which depends on whether personal rights are restricted and whether it is obviously unfair; when signing before marriage, the relationship between the two parties is not determined, and more attention should be paid to not violating public order and good customs. It is suggested to draft and notarize in the form of property agreement.

How to prove that the other party "derailed" the trigger clause?

Evidence includes: chat records, bank transfer and hotel registration records, photos and videos, police reports, and documentation from the employer or community; a final and effective court judgment (such as a divorce decree finding fault or an administrative penalty decision) carries the strongest evidentiary weight. The agreement may stipulate that “the findings in the final legal document shall prevail” to minimize disputes.

Does the agreement require both parties to have witnesses sign it?

is not mandatory, but can enhance the proof. A written signature is valid; having the signatures of witnesses, fingerprint seals, and a complete date can help reduce the risk of later denials of signing. Notarization carries the strongest evidentiary force; for transactions involving significant assets, it is advisable to have the document notarized and retain the original.

After signing a property agreement, are daily incomes still treated as joint property?

See the agreed-upon scope. If the agreement covers only specific property (e.g., a particular residential property), the remaining marital property shall still be governed by the statutory regime of joint ownership; if the agreement provides that all premarital and marital property is owned separately by each spouse, such arrangement shall prevail. When drafting the agreement, the scope of the arrangement must be clearly specified to avoid confusion arising from applying some provisions by agreement and others by statute.

The agreement stipulates a substantial “divorce penalty” for infidelity—can it be enforced?

It depends on the nature. Purely punitive damages provisions may be reduced or disallowed for lack of a basis in actual harm; provisions that link damages to the specific allocation of property and are drafted as property agreements are more enforceable. When drafting the provisions, avoid setting excessively high compensation amounts; limit compensation to property restitution and reasonable losses to enhance the certainty of court rulings.

What should I do if the other party goes back on their word and refuses to cooperate with the transfer of ownership?

If the agreement is notarized or confirmed by the court, it can directly apply for compulsory execution or claim liquidated damages according to the agreement; if it is not confirmed, it is necessary to sue for property disputes after divorce, and transfer the ownership according to the effective documents. During the litigation period, it can apply for preservation of the property involved in litigation.

9. Practical Insights from a Lawyer

"If you cheat again, you will leave the house clean". Many people feel very angry when they sign it. It is not easy to find it until they get divorced. In practice, it is important to distinguish whether it is a promise of loyalty that restricts personal or punitive, or a written property agreement on property ownership and consequences, and the degree to which the two writings are supported varies greatly. Therefore, instead of getting hung up on whether the signed document is actually effective, focus on how it is drafted and what it contains—translate the written terms into legally recognizable provisions.

If you want such agreements to hold up, the key is to reframe them from emotional penalties into property arrangements: clearly specify which assets belong to whom and how they will be handled under what circumstances, with independent clauses, clear consequences, and practical enforceability—rather than vaguely writing the four words “leave with nothing.” Sign to leave a mark, indicate the time, if necessary, through notarization to enhance certainty, and pay attention to whether the signing of both parties are true and voluntary, whether forced to sign. These details will all affect whether it can be adopted in the future; a casually written sentence often does not stand up to scrutiny.

What needs to be reminded is that it is not reliable to bet all hopes on a single agreement: either it may be rejected because of the problem of the clause itself, or it may be lost because there is not much property that can be divided in the name of the other party. It is safer to write clearly the ownership of important property in the daily use of legal property agreements, and then cooperate with other evidence. Don't expect to rely on a harsh word to hold down the other party during the negotiation. It is the business to put the part that can be implemented into practice. Emotional words cannot solve the problem of real money.

Whether the "clean-out" agreement can be fulfilled depends on three variables: whether the form is a written property agreement, whether the conditions point to a clear fault behavior, and whether the scope of the property is clear and specific. It is suggested that the "clean body out of the house" be completed into a written agreement on the property of the husband and wife, clearly set out the scope of property, the conditions of attribution and the consequences of breach of contract, delete the provisions restricting personal rights, and retain the evidence of the other party's breach of contract. At the same time, it is suggested that even if the agreement is valid, the court cannot be expected to mechanically implement the "full clean body". The principle of fairness and basic living security are the bottom line of judicial review.
