[Direct answer]In the Beijing area, the division of the increase in value of pre-marital stocks after marriage depends on the nature of the increase. According to Article 1063 of the Civil Code of the People's Republic of China (effective January 1, 2021), a party's pre-marital property is the personal property of that party; according to Article 1062, the income during the marriage is generally considered joint marital property. According to Article 26 of the Interpretation of the Supreme People's Court on the Application of the Marriage and Family Chapter of the Civil Code of the People's Republic of China, the income from a party's personal property after marriage, except for the fruits and natural appreciation, shall be recognized as joint marital property. Therefore, if the pre-marital stocks only generate natural appreciation due to market fluctuations after marriage, they are generally still considered personal property; if the increase and income after marriage result from frequent transactions and management by the party, they may be recognized as joint marital property. It is recommended to distinguish the accounts and keep transaction records to clarify the nature. Similar issues can be referred to for reference.Divorce litigation and family disputesColumn.

1. Problem background and typical scenarios

Such disputes often arise in several situations: first, opening a stock account and holding stocks before marriage, with the account continuing to exist and the market value increasing after marriage; second, frequently buying and selling stocks and adding funds to the pre-marital stock account after marriage, generating significant profits; third, dividends or bonus shares being distributed from pre-marital stocks after marriage; fourth, pre-marital stocks being mixed with post-marital salaries and being difficult to distinguish; fifth, disputes over the nature of the appreciation during the divorce. In practice, courts usually review whether the stocks were actually managed after marriage, the frequency of transactions, and the source of funds, distinguishing between natural appreciation and active management income, and then determining whether they should be included in the division of assets.

II. Key points of contention

First, the definition of the nature of the appreciation: whether it is a natural appreciation or active management income. Second, the proof of the frequency of transactions and energy input after marriage, which determines whether the appreciation belongs to the common property. Third, the distinction between pre-marital and post-marital funds, and how to identify the additional funds. Fourth, the nature of stock dividends and stock splits. Fifth, the allocation of the burden of proof: the party claiming that the assets belong to the common property must prove the post-marital management actions. Sixth, the investigation of account control and usage. The specific determination shall be based on the current effective laws and regulations and judicial rulings.

III. Professional analysis by Henglue Lawyers

Based on the practical experience of the lawyers handled by our firm, the key to resolving disputes over pre-marital stock appreciation lies in fixing the account transaction records and trade records. The first step is to retrieve the securities account opening time, the details of fund deposits and withdrawals before and after marriage, and the transaction commission records to prove that the stocks were acquired before marriage. The second step is to distinguish whether there were frequent transactions after marriage. If there were no operations after marriage and the stocks only fluctuated with the market, the appreciation would be more likely to be recognized as natural appreciation and belong to the individual. If there were continuous buying and selling, additional funds and generated profits after marriage, the corresponding profits and appreciation might be recognized as joint property. The third step is to clarify the sources of funds deposited after marriage. The appreciation corresponding to funds deposited from post-marital income such as wages is usually included in joint property. In such cases, the lawyers handled by our firm pay attention to restoring the evolution of property with objective transaction records to avoid the parties losing their personal property rights due to account confusion.

5. Henglu Law Firm's Reminder

Risk Warning: First, the dividing line between natural appreciation and active management income is crucial. Frequent transactions after marriage carry greater risks. Second, the mixing of funds may weaken personal property claims, so it's best to keep accounts separate. Third, the nature of dividends and stock splits needs to be determined based on the account status. Fourth, evidence collection focuses on transaction records and payment records, and it becomes more difficult to retrieve them after the deadline. In addition to stock appreciation, issues such as real estate, creditor's rights and debts, inheritance, and corporate contracts can be referred to separately for further analysis.Property transactions and construction projects、Creditor's rights and debts, and enforcement cases,Inheritance and division of assets、Business and contract disputes in enterprises、Beijing Henglu Law FirmThe column obtains professional support.

VI. Frequently Asked Questions

It depends on the nature of the value-added. According to Article 26 of the Interpretation of the Civil Code and the Marriage and Family Code, the income generated from a spouse's pre-marital stocks after marriage, except for the interest and natural appreciation, is recognized as joint property. If the natural appreciation after marriage is solely due to the rise in market prices and not actual management, it is usually still considered personal property; if the appreciation and income are generated from frequent transactions and operations after marriage, they may be recognized as joint property. It is recommended to keep the account statements to prove the nature of the income.

The following items should be collected: First, the opening time of the securities account and proof of the stocks held before marriage; Second, screenshots of the market value before marriage and records of the market value at various points after marriage; Third, transaction orders and cash deposit/withdrawal records after marriage, to prove the transaction frequency and the source of funds; Fourth, evidence distinguishing whether the additional funds after marriage belong to pre-marital or post-marital assets; Fifth, records of dividends and stock splits.
