One, Case Review

Tang Moumou and Peng Moumou were acquainted in their early years, and both were in the continuation of their marriage with non-parties in 1990. Peng Moumou's first marriage was only dissolved through court mediation in October 2000, and he subsequently registered for marriage again, with this marriage relationship continuing to this day; Tang Moumou's first marriage ended in April 1992.

Tang Moumou claims that he and Peng Moumou lived together continuously from 1990 to 2014, forming a long-term cohabitation relationship. During the cohabitation, Tang Moumou invested in the construction of the residential land house in Haizhu District, Guangzhou in 2001. The house was built in 2003 and rented out for management. Therefore, he requests confirmation of his ownership of 50% of the residential land house, and also claims the corresponding compensation and resettlement rights. During the lawsuit, Tang Moumou voluntarily withdrew his claims related to the demolition compensation.

Peng Moumou denied the existence of a cohabitation relationship between the two parties, believing that the relevant evidence has flaws. The procedures and expenses related to the homestead and the house were all borne by himself, and the house should be owned by the individual. There was a huge difference between the two parties over the fact of cohabitation and the ownership of the house. After failing to reach a consensus, Tan Moumou filed a lawsuit with the court. [Case number: (2024) Yue 01 Minzhong 5200].

Case outcome

The first-instance court, considering the evidence submitted by both parties, their marital status, and relevant legal provisions, made the following determination: The evidence submitted by Tan Moumou is flawed and cannot form a complete evidence chain, neither proving the existence of a long-term cohabitation relationship between the two parties nor proving that he invested in the construction of the house in question. Moreover, both parties had legal spouses for many years, and even if the cohabitation fact is true, such behavior constitutes an improper relationship between men and women that violates public order and good customs. Considering the objective facts that the registration of the residential land use rights and the payment records for the house's various fees are all in the name of Mr. Peng, the first-instance judgment rejected all of Tan Moumou's claims.

The second-instance court, after reviewing all the evidence and the trial process, confirmed that the first-instance court's determination of facts was clear and the application of law was correct. The second-instance court also clarified that scattered unilateral statements, written materials with formal defects, and testimonies of witnesses who did not appear in court cannot serve as valid evidence for recognizing a long-term cohabitation relationship; in conjunction with the judicial interpretation on the time limit for a factual marriage, neither party constitutes a factual marriage. The final judgment was to reject the appeal and uphold the original judgment.

Chapter 3: Experience in Handling Cases

(1) Dao Hua lawyer believes

In the process of handling marital and family disputes, it is not uncommon for parties to file claims regarding cohabitation relationships and property ownership. This case fully presents the court's approach and standards for adjudicating such cases, which has strong reference value for the handling of similar cases. Civil litigation follows the statutory rules of evidence, and the party claiming rights shall submit a complete and mutually verifying chain of evidence. In this case, the evidence presented by Tan Moumou has issues such as formal defects and weak proof effectiveness, and has not reached the statutory standard of proof, which is also the direct reason why its claims cannot be accepted.

Disregarding the issue of evidence, the parties spent most of their time in a marriage with non-participants. The act of cohabiting with someone else while married is itself an improper relationship between a married person and another, which goes against public order and good customs. The law holds a negative attitude towards such cohabitation relationships. In this case, the parties claim that they constitute a de facto marriage and assert property rights accordingly. However, in light of the current judicial interpretations on marriage and family matters, February 1, 1994, is the statutory time limit for recognizing a de facto marriage, and a de facto marriage requires that neither party has a legally valid spouse at the time. This case clearly does not meet this condition. Moreover, the establishment of bigamy in fact also requires a prior marriage or de facto marriage as a basis, so this case does not constitute bigamy in fact. This also clarifies the common misconception that long-term cohabitation is directly equivalent to bigamy in fact.

The establishment of property claims often relies on the identification of basic identity relationships and investment facts. The claimant's request for property division is based on the establishment of a cohabitation relationship and the individual's investment in building the house. Due to the inability to establish the cohabitation relationship, and also because they failed to provide evidence to prove the fact of investing alone in building the house, the corresponding claim for property division lost factual support and ultimately did not receive support from the court. On a comprehensive review of the case, each judgment viewpoint of the court was strictly made in accordance with the law, both upholding the basic principles of the marriage system and adhering to the principle of evidence-based judgment in civil litigation.

(2) Daohua Lawyer Reminds

The number of domestic disputes arising from the identification of cohabitation relationships and the division of real estate properties is continuously increasing. Many parties, due to their negligence in preserving evidence in the early stage and unclear understanding of legal concepts related to marriage, find it difficult to obtain legal support for their legitimate claims, and such disputes are also gradually becoming common difficulties in the field of domestic affairs. Proper evidence preservation and division of rights and responsibilities in daily interactions and economic transactions can reduce contradictions and differences from the source and comprehensively safeguard personal legitimate rights and interests.

When there are situations such as cohabitation, joint investment in purchasing or constructing real estate, it is necessary to systematically organize and properly preserve written materials, payment receipts, communication records, and other types of evidence, clearly defining property ownership and investment ratios, and eliminating the practice of relying solely on oral agreements to determine rights and obligations. At the same time, it is also essential to accurately distinguish the legal boundaries between extramarital cohabitation, de facto marriage, and legal marriage, fully understand the legal consequences corresponding to different forms of interaction, and consciously comply with the relevant legal provisions of marriage and family as well as social public order and good customs.

The People's Courts always adhere to the principle of evidence-based adjudication in handling such cases. Facts claims lacking effective evidence are difficult to gain judicial support. Faced with domestic disputes where personal relationships and property rights are intertwined, relying solely on individuals to handle litigation is prone to insufficient evidence and legal application errors, which may affect the course of the case. In complex domestic cases involving issues such as cohabitation recognition and property division, it is particularly necessary to engage professional family law lawyers. The Daohua Marriage and Family Law Team has long been committed to the field of marriage and family law, familiar with the judicial recognition rules of cohabitation relationships, actual marriages, and bigamy, proficient in the key points of dividing and disposing of immovable properties such as courtyard houses, skilled in sorting out evidence chains and formulating litigation strategies, and can provide systematic legal solutions for individual cases, helping parties to properly resolve disputes and fully protect their legitimate rights and interests.
