[Direct answer]Not necessarily. Whether large debts are shared depends on three factors: if the couple signs the agreement together or acknowledges it afterwards, they will share the responsibility; if one party borrows money in their own name for the family's daily needs, they will share the responsibility; and for large debts exceeding daily needs, the borrower will generally bear the responsibility themselves - unless the creditor can prove that the money was used for the couple's joint life, joint production and operation, or based on the mutual intention of both parties. The burden of proof for large debts lies with the creditor, which is a protective mechanism provided by the Civil Code.

1. Problem background and typical scenarios

One party signs a multi-million-yuan debt outside, while the other party is completely unaware of it. When it comes to divorce, the creditor comes knocking on the door, demanding: "The husband and wife are one body, and they should repay the debt together." In the dispute over sharing large debts, on the one hand, there is the transaction security of the creditor; on the other hand, there is the property safety of the spouse who did not borrow the money. The Civil Code uses the rule of "joint debt and joint signature + purpose penetration" to draw a line between the two parties.

II. Key points of contention

First, the determination of joint debt and joint signature and subsequent ratification. Second, the definition of the scope of "family daily life needs". Third, the allocation of the burden of proof for large-scale debts beyond daily needs. Fourth, the determination criteria for joint production and operation.

III. Professional analysis by Henglue Lawyers

First, the legal framework: Article 1064 of the Civil Code of the People's Republic of China is the general principle for handling marital joint debts—debt incurred through joint expressions of intent, such as a joint signature or a spouse's subsequent acknowledgment, as well as debt incurred by one spouse in the name of the family for daily living needs during the marriage, are considered marital joint debts. Debt exceeding daily living needs does not fall under joint liability, unless the creditor can prove that the debt was used for the couple's common life, joint production and operation, or based on the couple's joint intent. After reading the three-layered structure, the conclusion is clear: joint signature and acknowledgment constitute ironclad joint debt, while daily expenses are presumed joint debt, and large-scale debts follow the principle of "individual liability in principle, joint liability in exception." Second, the boundaries of "daily living needs": The scope of daily household agency rights includes regular expenses such as clothing, food, housing, transportation, medical care, education, and normal social interactions. Courts across China generally link the threshold for such expenses to local income levels. Loans of hundreds of thousands or even millions of yuan typically exceed the scope of daily household needs—spouses who borrow large sums need not panic. Third, the focus of defense and attack for large-scale debts: Creditors must prove "use for common life or joint operation." Common evidence includes fund flow (loan transferred to family accounts, payment of mortgage/tuition/renovation costs), beneficiary evidence (family assets increased due to the loan), and joint participation evidence (spouse involved in operation, co-signing relevant documents). For the non-borrowing spouse, defense lies in cutting off the funds—proving the loan went to personal consumption, gambling, or sole-operated losses, never entering family accounts or benefiting the family. If evidence fails to meet standards, the creditor bears adverse consequences. Fourth, identifying joint production and operation: This is the most common channel for converting large-scale debts into joint liability—when spouses jointly run a business, participate in management, and use profits for family needs, related operational loans are easily deemed joint debts. If only one spouse operates in their own name, the other never participates, and profits do not enter the family, the debt remains personal. Key factors include registration (whether both are shareholders or operators), participation (attendance, decision-making, and receiving accounts), and beneficiary (whether operational income becomes the family's main source). Fifth, divorce settlement and external legal effect: Divorce agreements designating large-scale debts as the sole responsibility of one spouse are only binding within the couple. Creditors can still sue both parties. If the non-borrowing spouse is forced to repay, they can seek full recovery from the other party according to the divorce agreement—thus requiring divorce agreements to specify the nature and responsibility of each debt. At the litigation stage, claim the nature of the debt to avoid being "first compensated then pursued." For suspected fraudulent debts (e.g., sudden borrowing before divorce or collusion with relatives to forge loan agreements), apply to review fund flows and loan rationality, and the perpetrators of fraudulent litigation face legal liability.

IV. Practical suggestions and legal basis

The first step is to be cautious when signing documents: Do not sign large-amount loans for your spouse, and do not easily issue declarations of recognition. The second step is to segregate funds: Keep separate accounts for family and business purposes, and maintain records of large-scale fund transfers. The third step is to actively provide evidence: When sued, cut off the joint debt chain from three perspectives: purpose, beneficiary, and participation. The fourth step is to clarify agreements: When divorcing, list the nature of the debt and the responsible parties item by item. Legal basis: Articles 1064 and 1089 of the Civil Code of the People's Republic of China, and relevant provisions of the Interpretation of the Marriage and Family Chapter of the Civil Code of the People's Republic of China issued by the Supreme People's Court; the specific application shall be subject to the currently effective regulations.

5. Henglu Law Firm's Advice

Three key points regarding large debts: if you haven't signed the agreement or given your consent afterward, you're generally not liable for the debt; if the creditor claims that the debt was used for "joint living expenses," the burden of proof lies with them, not you; when dividing debts in a divorce agreement, the focus is on protecting against internal disputes rather than external ones. If you're implicated in a legal dispute involving joint debts or family disputes, remember to seek compensation afterward.

VI. Frequently Asked Questions

Q1: My spouse borrowed several million yuan without my signature. Do we need to repay it together?

In principle, it is not necessary. For large debts exceeding the family's daily living needs, the creditor shall provide evidence to prove that the debts are used for common living or business purposes. If the creditor fails to provide such evidence, the debtor shall bear the liability for the debts himself/herself.

Q2: If the loan is deposited into the family account, does it count as a joint debt?

There are obvious risks. If the funds are deposited into family accounts and used for family expenses such as mortgages and education, they may easily be deemed as being used for shared living and expenses that should be borne jointly by both spouses.

Q3: If I helped my spouse's company with bookkeeping, would that count as joint operation?

Evidence of participation in business management (bookkeeping, decision-making, and receipt of payments) will strengthen the determination of joint business operations. Whether they share the profits or not should be judged comprehensively based on the destination of the business income.

Q4: The divorce agreement stipulates that the debts belong to the other party, but the creditor is still pursuing me. What should I do?

The internal agreement does not bind the creditor, and after repayment, the creditor can seek compensation from the other party according to the divorce agreement; in the litigation stage, the creditor should claim that the debt is a personal debt.

Q5: Is the IOU that the other party suddenly produced before the divorce valid?

It is possible to question the authenticity and rationality of the claim and request a review of the fund transaction records. If the debt involves false litigation, the court may be requested to impose sanctions on the party involved.
