[Direct answer]In the Beijing area, if there is no agreement or the agreement is unclear, the joint and several liability guarantee period is six months from the date of expiration of the main debt performance period. Within these six months, the creditor must assert his rights against the joint guarantor - sending a collection notice, initiating litigation or arbitration all count - if the creditor asserts his rights, the statute of limitations for the guarantee contract shall be calculated from the date of assertion; if the creditor fails to assert his rights even once within six months, the guarantor shall be exempt from liability according to law. The non-occurrence of suspension, interruption and extension of the guarantee period is the most easily overlooked aspect of creditor protection.

1. Problem background and typical scenarios

Many guarantees occur between acquaintances: friends borrow money, and the guarantor signs the promissory note without anyone mentioning the guarantee period. Two years later, the borrower absconds, and the lender seeks the guarantor, who simply says "the guarantee period has passed" to evade responsibility. The lender often doesn't understand: the statute of limitations for the main debt still has several years left, so why is the guarantor exempt from liability? This is precisely the manifestation of the guarantee period being independent of the statute of limitations.

II. Key points of dispute

First, the starting point: the date on which the main debtor's performance period expires, and the difference between this date and the starting point of the statute of limitations for the main debt lawsuit. Second, the effectiveness of contractual terms: how to handle vague expressions such as "the guarantee shall last until the loan is repaid in full". Third, the form of asserting rights: the effectiveness of written collection, litigation, and arbitration, and the preservation of evidence. Fourth, whether the guarantee period can be revived after expiration: the effectiveness of the guarantor's reconfirmation or partial repayment.

III. Professional analysis by Henglue Law Firm

From Henglue Lawyer's experience in handling guarantee disputes, the key points of cases involving joint and several guarantees can be summarized into four aspects: 1. **Classification**: If the agreement stipulates that "the guarantee period shall commence from the date of the expiration of the main debt's performance period and last for two years", this is a clear agreement. However, if the agreement states "until the principal and interest are fully repaid", this is considered an unclear agreement, and the guarantee period should still be determined as six months according to law. Many creditors fail because they mistake the unclear agreement as a fixed time limit. 2. **Starting point**: If the main debt is repaid in installments, the guarantee period shall commence from the date of the expiration of each installment. If the loan is recovered in advance, the guarantee period shall commence from the date of early repayment. 3. **Assertion**: Serving a collection notice to the joint guarantor in person is legally effective. Evidence of collection via WeChat or SMS messages can also be recognized, but it must be able to prove the recipient and the date of delivery. Litigation is the most reliable method. 4. **Statute of limitations conversion**: After successful assertion within the guarantee period, the three-year statute of limitations applies. Thereafter, the ordinary statute of limitations rules apply, and the interruption events resume their effect. The defenses of the guarantor also revolve around these four aspects: daily verification of the start and end dates of the guarantee period, assertion of defects in the service of the notice, and verification of whether the collection target is the guarantor himself. The outcome of the dispute ultimately depends on the written evidence along the timeline.

IV. Practical suggestions and legal basis

The first step is to review the guarantee documents and the loan contract to determine the expiration date of the performance period and the start and end dates of the guarantee period. The second step is for the creditor to claim against the guarantor in a traceable manner within this period, and to obtain a signed receipt for the collection letter in person or retain the return receipt for the mailed letter. The third step is for the guarantor to verify whether the period has expired and, if so, to promptly issue a defense opinion exempting them from liability. The fourth step is to transfer claims made within this period to the statute of limitations management and retain evidence of interruption. Main legal basis: Article 692 of the Civil Code of the People's Republic of China (effective from January 1, 2021) regarding the guarantee period; Article 693 regarding the exemption from guarantee liability; and Article 694 regarding the statute of limitations for guarantee debts; The Interpretation of the Supreme People's Court on the Application of the Civil Code Concerning the Guarantee System (effective from January 1, 2021) regarding the handling rules for unclear agreements on the guarantee period; Specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

There are three key points regarding the guarantee period: if there is no agreement, the guarantee period is six months; if the agreement is unclear, the guarantee period is still six months; during the guarantee period, the creditor must file a claim against the guarantor, and leaving a written record is the only absolute requirement; once the guarantee period expires, the guarantor's liability is exempted, and there's only a chance of recovery if the creditor acknowledges the debt afterwards.

VI. Frequently Asked Questions

Q1: Can the warranty period be interrupted?

No. The guarantee period is a preclusive period, and there will be no suspension, interruption, or extension of it. Only if the creditor asserts his rights against the guarantor within the guarantee period can the protection of the three-year statute of limitations be activated.

Q2: Is the agreement that "the guarantee shall remain in effect until the loan is repaid" valid?

According to the interpretation of the guarantee system in the Civil Code, such agreements are considered to be unclear, and the guarantee period is still calculated from the date of the expiration of the main debt's performance period for six months, rather than an indefinite guarantee.

Q3: What should the guarantor do if he/she has repaid part of the money after the guarantee period has passed?

If the guarantor voluntarily repays the debt or agrees in writing to continue to provide a guarantee after the expiration of the guarantee period, this constitutes a new expression of intent, on the basis of which separate claims can be made. However, mere oral acknowledgment generally does not automatically restore the guarantor's liability. Written evidence is required in such cases.

Q4: Is it only collecting the debt from the borrower and claiming it against the guarantor?

This does not apply to joint and several liability guarantees. Creditors must assert their rights directly against the guarantor, and if they only collect the debt from the borrower, the guarantee period will be calculated as usual, and the guarantor will be exempt from liability after it expires.

Q5: If the principal debt is extended, how is the guarantee period calculated?

The extension of the principal debt without the written consent of the guarantor shall not be effective against the guarantor, and the guarantee period shall still be calculated from the expiration date of the original performance period; if the guarantor agrees to the extension in writing, the guarantee period shall be calculated from the expiration date of the extended performance period.
