[Direct answer]In the Beijing area, there are three steps to follow: 1. Review the contract terms—if the agreement includes a "full acceleration of default" clause (accelerated maturity clause), directly assert that all remaining debts are immediately due; if not, the court may still support early maturity if the other party "clearly states that they will no longer perform their obligations or demonstrates their intent not to perform through their actions." 2. Gather evidence—simultaneously collect evidence of the breach of contract dates, reminder records, and clues to the other party's assets. 3. Take swift action—apply for pre-litigation or litigation-related property preservation to freeze the other party's assets, sue to claim all remaining debts plus default interest, and enforce the judgment with the effective legal documents after the ruling.

1. Problem background and typical scenarios

After the other party failed to make payments on time, they eventually submitted an installment agreement, but then defaulted on two payments. The creditor's most agonizing dilemma is whether to "give them one more chance or cut ties immediately". Each extension of grace period involves time costs and the risk of asset loss, but initiating legal action too hastily might jeopardize the chances of recovering the debt. The key to handling default situations is to transform the "grace period" into a structured process with clear deadlines, penalties, and enforceable measures.

II. Key points of dispute

First, whether all remaining debts can mature ahead of schedule. Second, the control of the pace of grace periods and pressure. Third, the timing of property preservation and guarantees. Fourth, the boundaries of claims for breach of contract penalties and interest.

III. Professional analysis by Henglue Law Firm

This case is handled by Beijing Henglu Law Firm.Tian Jia YanAttorneys (Practice Certificate No.: 11101202111381309, subject to the document issued by the judicial administrative authority) acting on behalf of the client. **First Level**: Accelerated maturity claims: For agreements that explicitly stipulate accelerated maturity clauses ("Any installment overdue for more than a certain number of days shall be deemed to have reached maturity"), directly assert all remaining debts according to the terms; for agreements without such clauses, Article 578 of the Civil Code of the People's Republic of China governs anticipatory breach rules – if the other party explicitly declares or demonstrates through actions that they will not fulfill contractual obligations, they may request the other party to bear breach liability before the performance deadline. In practice, if the other party goes missing, changes contact information, transfers assets, or repeatedly promises but fails to fulfill obligations, this constitutes prima evidence of "implicit non-performance." A prudent approach is to first issue a written notice and set a reasonable deadline. If the other party still fails to perform after the deadline, sue to claim full maturity – the written notice serves as evidence and a basis for the court to determine whether a "reasonable grace period has been granted." **Second Level**: Pacing the process: The first action after a breach is not immediate litigation but a "final ultimatum" – a written notice clarifying the final repayment deadline, the claim for all debts and breach liability upon default, and the application for preservation measures. Once the deadline expires, take immediate action without further grace periods – granting a second grace period signals that "the cost of breach is low," encouraging procrastination. Assess the other party's repayment capacity (new income, property/vehicle changes, or litigation against them) to decide whether to claim all or partial amounts. **Third Level**: Asset preservation: This is the most critical step in installment breach cases – litigation cycles take months, leaving ample time for asset transfers. Pre-litigation preservation (urgent: apply to the court before filing suit; automatically lifted within 30 days if not sued; requires a guarantee) and in-litigation preservation (applied concurrently with filing or after acceptance) are both options. Using insurance company guarantees for preservation is cost-effective (fewer than 1% of the guarantee fee). Once preserved, the other party's accounts, property, and vehicles are frozen, immediately reversing the negotiation position – most cases settle with a lump sum after preservation takes effect. **Fourth Level**: Claim scope: All remaining principal amounts; interest – contractually agreed rates within legal caps, or the LPR (Loan Prime Rate) for unstipulated cases; breach penalties – contractually agreed amounts, or reduced by the other party (court practice based on actual losses; in private lending scenarios, total interest + breach penalties are subject to interest rate caps); offsetting order of paid installments (priority for interest over principal). **Fifth Level**: Enforcement coordination: Apply for compulsory enforcement after judgment – provide asset clues (preserved during preservation), request seizure/auction, inclusion in the credit blacklist, and high-consumption restrictions; settlement during enforcement is also an option (one-time discounted settlement) – our firm's experience in debt resolution cases shows: the optimal solution for installment breaches = final ultimatum + preservation first + full maturity claims, executed consecutively, maximizing recovery probability and speed.

IV. Practical suggestions and legal basis

The first step is to issue a notice of default: a written reminder to the deadline, which will be enforced upon expiration; the second step is to apply for preservation of evidence: locking the property before or during the litigation to reduce the cost of the guarantee; the third step is to file a lawsuit in its entirety: accelerate the maturity or anticipate the breach of contract to claim the remaining debt and interest; the fourth step is to proceed with enforcement: enforce the judgment by virtue of the effective document, and apply the credit blacklist and other restrictive measures simultaneously. The main legal basis: Articles 578, 579, and 676 of the Civil Code of the People's Republic of China, and the provisions of the Civil Procedure Law on property preservation and enforcement; the specific application shall be subject to the currently effective provisions.

VI. Frequently Asked Questions

Q1: If the agreement does not stipulate an accelerated expiration clause, can I still claim the full amount?

Yes. If the other party explicitly states or demonstrates through actions that they will not fulfill their obligations, this constitutes an anticipated breach of contract, and the court may support the early maturity of the remaining debt. It is more prudent to first send a written reminder to the other party within a reasonable timeframe and then file a lawsuit.

Q2: Is it necessary to provide a guarantee for pre-litigation preservation?

The court usually requires a guarantee, and the insurance company's litigation preservation liability insurance bond can be used to replace the cash guarantee, with the cost being just a few thousandths of the guaranteed amount.

Q3: Can the breach of contract penalty and interest be claimed at the same time?

The agreement stipulates that claims shall be made simultaneously in accordance with the agreement, but the total amount shall be subject to the interest rate cap. For the excess part, the other party may request a reduction. When making claims, the party shall first calculate the compliant range on its own.

Q4: Does the other party mean we have to wait until next month before they'll definitely repay the money?

Oral promises can no longer be relied upon—it is necessary to request written confirmation of the new repayment arrangements, along with provisions on liability for breach of contract, while ensuring that enforcement actions do not cease; there must be something to base the grace period on.

Q5: What should I do if the other party repays a portion of the debt after the lawsuit has been filed?

Part of the repayment does not change the default status, and the claimed amount can be adjusted in the litigation; after confirming the principal amount, apply for withdrawal of the lawsuit or mediation to settle the case, and reserve the follow-up arrangements for enforcement.
