[Direct answer]In principle, it doesn't count. Stock trading doesn't belong to the daily needs of a family. For large-sum loans exceeding daily needs, the creditor must provide evidence that the funds were used for the couple's common life or joint production and operation (Article 1064 of the Civil Code of the People's Republic of China, implemented on January 1, 2021); if the loan is directly transferred to a securities account and operated by one party alone, the court will generally regard it as the borrower's personal debt, and the spouse will not bear the repayment responsibility. The exception is: if the stock trading income is used for family expenses and the spouse actually benefits from it, or if the spouse knows about and participates in the operation, it may be regarded as a joint debt.

I. Problem Background and Typical Scenarios

The husband secretly borrowed hundreds of thousands of yuan to invest in the stock market without his wife's knowledge. After suffering losses, he resorted to borrowing more money to pay off his debts. It wasn't until the creditors came to collect the debt that the wife finally found out. On one side, the couple worried about being saddled with huge debts, while on the other side, the creditors were eager to prove that "the money had gone into his family's account". In the end, how this debt would be settled depended on the evidence of the fund's flow.

II. Key points of contention

First, the qualification of stock trading—the distinction between individual investment behavior and family-run production and operation. Second, the tracking of capital flows—the evidence chain of funds being transferred to securities accounts after being deposited. Third, the determination of spouse beneficiaries—whether the profits from stock trading are deposited into family accounts. Fourth, the distinction between the nature of multiple loans in the situation of "borrowing to repay loans".

III. Professional analysis by Henglue Law Firm

The key to winning or losing such cases lies in two sets of bank statements. The first is the purpose of the loan: If the creditor claims it's a joint debt, they need to prove that the loan did not stay in the borrower's personal account, but entered the family's common property system. However, if the loan was directly transferred to the borrower's securities account, it precisely proves that it was a personal investment. In Henglue's practice, the most common evidence pattern is that the creditor lacks sufficient evidence (only promissory notes and transfer records), while the spouse can simply retrieve the securities account records and bank statements to prove that the funds "remained in the borrower's personal account." The second set of evidence concerns family benefits. Conversely, if the stock trading profits were transferred to the family account for purchasing a house, renovation, or children's education, or if the spouse was aware of the transactions and participated in them (the account is registered under the spouse's name, or chat records showing joint decision-making), there would be evidence to support the claim of a joint debt. Three details are worth noting: 1. If the borrower defends the loan as a "family investment," the court will examine whether the spouse participated in the account management, shared the funds, or was aware of the transactions. A mere verbal claim of "it's for the family" is insufficient. 2. For consecutive loans used to repay previous debts, the court must verify the funds' flow in detail. Transactions used for family expenses may be considered joint debts, while those used to repay previous debts should be classified separately. 3. In terms of litigation strategy, the unaware spouse should focus on submitting securities account and transaction records, bank statements, and family spending comparison tables to prove that the loan had no connection to family life. The creditor, on the other hand, should reflect on the lending process - requiring both spouses to sign for large sums is the only reliable approach. Beijing courts have already developed sophisticated methods for analyzing securities account and bank statement data, and verbal claims alone are unlikely to overturn the conclusion of the funds' flow.

IV. Practical suggestions and legal basis

Borrower's side: For large-amount loans, the couple should sign the contract together, or require the spouse to provide a letter of informed consent; the purpose of the loan should be written into the loan contract and the use of the funds should be regularly checked. Spouse's side: If any abnormalities are found, immediately save the securities account and bank transaction records to avoid making statements such as "I know about this money" under pressure from debt collectors; after being involved in litigation, promptly apply to retrieve the other party's securities transaction records. Main legal basis: Articles 1064 and 1065 of the Civil Code of the People's Republic of China, which came into effect on January 1, 2021; relevant provisions of the Interpretation (I) of the Supreme People's Court on the Application of the Marriage and Family Chapter of the Civil Code; the specific application shall be subject to the currently effective regulations.

5. Henglu Law Firm's Reminder

Here's the translation of the Chinese sentence into English, with a detailed explanation: \nFor each of the three parties: **Lender** — If a large-sum loan is not co-signed, they must accept the disadvantageous position of having to provide evidence; **Uninformed spouse** — Bank statements are the best defense, and remaining silent is less effective than actively providing evidence; **Borrower** — Using loans to repay loans will only turn personal debt into a family disaster. It's better to confess to your spouse and stop the damage as soon as possible. For large-sum loans, legal consultation one hour before lending is more effective than litigation a year after a dispute.

VI. Frequently Asked Questions

Q1: If the husband borrows money to invest in stocks and loses money, does the wife have to repay the debt?

It's generally not used. If stock trading exceeds the family's daily needs and the creditor cannot prove that the funds were used for the couple's joint life or business, it will be deemed as the husband's personal debt, and the wife will not bear the repayment responsibility.

Q2: If I use the money I earned from stock trading for household expenses, does the debt become a joint liability?

There's a possibility that if the income actually goes into the family account and is used for shared living expenses, the spouse will be deemed the actual beneficiary, and the chances of establishing joint debts will increase. However, the specific case still depends on the corresponding relationship between the amount, time, and degree of benefit.

Q3: The account is in my wife's name. Does it count as a joint debt?

When the account is registered in the real name of the spouse and the spouse participates in the operation or is aware of it, there is a clear tendency towards joint debt; if it is just a borrowing of the name, and the actual operation is carried out by one party alone, the determination of the real name is not the only criterion, and the decision should be made based on the evidence of each case.

Q4: What should the creditor do?

For the lending process, it is required that the couple sign the contract jointly or provide informed consent, and the purpose of the funds must be specified in the contract. For those who have already disbursed the loan, collect evidence showing that the borrowed funds have entered the family's asset system (such as records of purchasing a house or a car, and transfers between family accounts), and assess the need to promptly file a lawsuit to preserve the assets.

Q5: How long does it take to litigate such cases, and how much does it cost?

The acceptance fee is charged in proportion to the amount of the subject matter, and the attorney's fee is negotiated in stages. The first-instance ordinary procedure shall be concluded within six months. However, the period for retrieving securities transaction records and comparing multiple transaction records may be extended, and the specific timeframe shall be determined by the court.

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