[Direct answer]Generally, it is possible to claim for the return of the funds. According to Article 1062 of the Civil Code of the People's Republic of China, the wages, bonuses, and production and operation income earned by a couple during their marriage belong to their jointly owned property, and they have equal rights to dispose of the jointly owned property. If one party transfers a large amount of jointly owned property to a third party without the consent of the other party, it constitutes an unauthorized disposition and violates public order and good customs. The other party may claim that the gift is invalid and demand the return of the funds. If the transfer of funds is for the purpose of maintaining an improper relationship, the recipient generally cannot raise the defense of bona fide acquisition. In practice, the party claiming for the return of the funds needs to prove that the funds originate from the couple's jointly owned property, that the amount of the transfer is large and was made without consent, and that the recipient is a third party. It is also important to assert the claim within the statute of limitations.

1. Problem background and typical scenarios

During an extramarital affair, one party may transfer large sums of money, purchase gifts, or pay expenses on behalf of the third party, which is a common situation in divorce disputes. After learning about this, the other party is both angry and confused: Can this money be recovered? Who should be sued? How to prove it? There are three typical scenarios: First, transferring hundreds of thousands of yuan to the third party during the marriage and using it for consumption; Second, making disguised gifts through purchasing luxury goods, paying for housing and car loans, etc.; Third, transferring money in scattered amounts and conducting it in the form of red envelopes and daily expenses. Under different forms, the paths of evidence collection and recovery vary.

II. Key points of contention

First, the effectiveness of the gift act—is it completely invalid or partially invalid, and can the other party claim full restitution? Second, whether the funds belong to the couple's joint property and how to handle the personal property portion. Third, whether the donee can raise defenses such as good faith or having already consumed the funds. Fourth, how the burden of proof is allocated and what level of proof is required. Fifth, the litigation path for restitution—whether to claim it together with the divorce litigation or to file a separate lawsuit. These issues determine the feasibility and expected outcomes of protecting one's rights.

III. Professional analysis by Henglue Lawyers

Henglue Law Firm has summarized three practical points in marital property disputes. Firstly, the basis of legal effect: spouses have equal rights to dispose of joint property. If one spouse disposes of large amounts of joint property without authorization and in violation of public order and good customs, the gift act may be deemed invalid. According to Article 157 of the Civil Code, the property obtained through invalid acts shall be returned. Secondly, distinguishing the nature of the funds: if the funds come from the couple's joint property, the other spouse can claim a corresponding share of the return; if the funds are indeed the spouse's premarital personal property, the other spouse generally has no right to claim. However, if the joint marital property and personal property are mixed, the burden of proof will be increased. Thirdly, the defense of the donee: if the third party claims bona fide acquisition, it is generally difficult to establish, because the circumstances of obtaining the property without compensation and knowing that the other party is married do not meet the constituting elements of bona fide acquisition. The defense of having already consumed the funds usually does not affect the obligation to return, but may affect the scope of enforceable property. Fourthly, the litigation path: if the divorce litigation is ongoing, the claim can be raised simultaneously; if it is discovered after the divorce, the third party can be sued separately for return. Fifthly, the emphasis of evidence: transfer records, fund flows, proof of the parties' relationship, and the purpose of the funds are the core supporting the claim for return. In addition, for large-scale real estate or vehicle gifts, it is also necessary to deal with registration and depreciation issues. 恒略律师在婚姻财产纠纷中总结了三点实务要点。其一，效力基础：夫妻对共同财产享有平等处理权，一方擅自处分大额共同财产且违背公序良俗的，该赠与行为可被认定无效，依民法典第一百五十七条，无效行为取得的财产应当返还。其二，区分款项性质：若款项来源于夫妻共同财产，可主张返还相应份额；若确系一方婚前个人财产，则另一方通常无权主张，但婚内共同财产与个人财产混同的，举证难度会加大。其三，受赠人抗辩：第三者主张善意取得的，一般难以成立，因为无偿取得且明知对方已婚的情形不符合善意取得的构成要件；已消费的抗辩通常也不影响返还义务，但可能影响可执行财产的范围。其四，诉讼路径：若离婚诉讼正在进行，可一并主张；离婚后发现的，可另案起诉第三者要求返还。其五，举证重点：转账记录、资金流向、双方关系证明与款项用途，是支撑返还主张的核心。此外，涉及大额不动产或车辆赠与的，还需处理登记与折价问题。

5. Henglu Law Firm's Advice

VI. Frequently Asked Questions

Q1: Can the money transferred by the spouse to the mistress be fully recovered?

Generally, it is possible to claim a refund, but the scope of the claim depends on whether the funds belong to the couple's joint property. For large-scale gifts that belong to joint property, it is possible to claim their invalidity and the return of the corresponding shares; if they are indeed the spouse's personal property, the other party generally has no right to claim. If the joint property is mixed with personal property, it is necessary to distinguish them through evidence, and the refund ratio may be adjusted accordingly.

Q2: What evidence is needed to sue the third party?

The core evidence includes transfer records and bank statements, materials showing the existence of an extramarital relationship between the two parties, explanations of the purpose of the funds, and income and property certificates that can prove that the funds come from the couple's joint property. The evidence should form a complete chain, showing the amount, time, and nature of the gift, to facilitate the court's determination.

Q3: The mistress said that the money has already been spent. Can I still get it back?

It can still be claimed. The establishment of the obligation to return the money does not depend on whether the funds still exist. Consumption of the funds usually does not constitute a valid defense, but it will affect the scope of the actual enforceable property. If it can be proven that the funds have been converted into property such as real estate and vehicles, the claimant can assert corresponding rights to the property or claim compensation in the form of a discounted value.

Q4: Can these claims be raised together in a divorce lawsuit?

Yes. If the divorce litigation is ongoing, you can file a request for return together, and the court will handle it during the trial. If you discover it after the divorce, you can also sue the third party for return in a separate case. Which path to choose depends on the progress of the litigation, the scope of the defendants, and the preparation of evidence. It is recommended to first assess the situation with a lawyer.

Q5: What is the statute of limitations for a lawsuit demanding return of property?

The general statute of limitations applies, which is usually three years, calculated from the date when the right holder knows or should have known that their rights have been infringed and the date when the obligee becomes aware of the infringement. After discovering the transfer of funds, it is necessary to secure evidence as soon as possible and assert rights in a timely manner to avoid losing the right to win the case due to exceeding the statute of limitations. In special circumstances, the determination should be based on the specific facts.

The above answer is based on the judicial practice in Beijing. The judicial interpretation in other provinces and cities may vary. For specific cases, please refer to the local rules and evidence situation.

If you are facing similar problems, it is recommended that you consult a professional lawyer as soon as possible with the evidence materials, so as to avoid missing the statutory time limit. →Divorce litigation legal services·Beijing Henglue Law Firm
