[Direct answer]Generally, it's not possible. A signed and effective inheritance division agreement is a contract that reflects the true intentions of all parties. There are only three legal grounds for revoking it: fraud, coercion, or a significant misunderstanding or manifestly unfair terms; if there are omitted assets or heirs, the omitted parts will be handled separately; and the omitted heirs can claim for a redistribution. Feeling that they "got a raw deal" is not a valid reason for revoking the agreement.

1. Problem background and typical scenarios

It's all too common for people to regret their decisions after signing agreements. For example, they might sign the agreement to reassure the elderly, but later feel cheated after the elderly pass away; they might sign the agreement without fully understanding its contents, and later claim they "didn't read the terms carefully"; they might discover that a sibling hid the mother's savings, and then feel the agreement is unfair; or they might want to renege on the agreement after the house has been transferred to their name due to intensified family conflicts. However, the law clearly distinguishes between legitimate regrets and futile attempts to renege on agreements. The boundaries between the two are well-defined.

II. Key points of contention

First, the legal nature of the agreement: the contractual attributes and the binding force after its entry into force. Second, the determination of the grounds for revocation: the standards of proof for fraud, coercion, major misunderstanding, and manifestly unfair terms. Third, the handling of omissions: separate remedies for omitting property division and omitting the listing of heirs. Fourth, statute of limitations management: the time limit for the right of revocation.

III. Professional analysis by Henglue Law Firm

The nature of the agreement must be defined first: A written agreement reached between heirs on the distribution of inheritance constitutes a contract, and once signed and effective, it is binding on all parties. In principle, no party may unilaterally retract their agreement – the court's attitude towards such agreements is to respect contractual autonomy and maintain the stability of established arrangements, which is the overarching principle. There are three statutory grounds for successfully revoking such agreements, each with its own evidentiary standards: 1. **Fraud or coercion** – If the existence of the inheritance was concealed (e.g., the agreement failed to mention a deposit in the mother's name that was later discovered) or the signatory was coerced into signing, the party subjected to fraud or coercion may seek revocation. Key evidence includes the "concealed facts" and the "causal relationship to the signing," often supported by bank statements, audio/video recordings of the signing process, or chat logs. Note that inheritance disputes often arise when one party claims "there's only this property" during the agreement signing, only to discover hidden assets later, allowing claims for the omitted assets separately rather than revoking the entire agreement. 2. **Major misunderstanding** – Misunderstanding the core terms of the agreement (e.g., mistaking a "temporary deferral of division confirmation" for a final division agreement, misunderstanding the property share ratio) requires proving both the "misunderstood content" and the "motivation for signing." Simply "not reading carefully" does not constitute a misunderstanding under the law; adults bear the obligation to carefully review signed documents. 3. **Manifestly unfair terms** – Exploiting the other party's vulnerability or lack of judgment to create a gross imbalance of rights and obligations (e.g., making elderly individuals sign waivers of inheritance rights while they are ill and mentally unclear). Note that revocation focuses on the structural unfairness at the time of signing, not simple "unequal distribution." Inheritance shares are negotiated voluntarily (e.g., favoring those who provide more care or are in financial hardship), and even full transfer to one party is acceptable as long as it's voluntary and truthful. **Procedural and time limits**: - The right to revoke must be exercised within one year from the date the party knows or should have known the grounds for revocation (90 days for major misunderstandings). - The revocation period starts from the date the coercive act ends. - Preclusive periods do not apply to revocation. - Late claims are ineffective. - Omitted assets (e.g., unmentioned deposits, shares, or demolition compensation) are handled via statutory inheritance or renegotiation. - Omitted heirs (e.g., children not notified during signing) may claim their share from the remaining estate, affecting previously divided agreements. **Two practical reminders**: 1. Seek legal advice before signing agreements (far cheaper than litigation later). 2. Document the signing process (现场拍照、关键对话录音) to prevent future accusations of coercion and preserve evidence.

IV. Practical suggestions and legal basis

First, risk control before signing: List all heirs and all assets, and have a lawyer review the clauses. Second, self-check before revoking: Find evidence based on the four elements of fraud, coercion, gross misunderstanding, and manifestly unfairness, and evaluate the chances of success before taking action. Third, prioritize statute of limitations: File a lawsuit within the revocation period (one year for gross misunderstanding, and 90 days for other cases). Fourth, handle omissions differently: Divide missing assets and list missing heirs according to supplementary distribution rules, without affecting the main parties to the agreement. Main legal basis: Articles 147 to 151 of the Civil Code of the People's Republic of China (Revocable Civil Legal Acts), Article 152 (Extinction of the Right of Revocation), and Article 1132 (Principle of Consultation on Inheritance); specific application shall be subject to the currently effective laws and regulations.

5. Henglu Law Firm's Advice

Three golden rules for regretting a division agreement: It's better to argue over the terms when signing than to renege on them afterward; there are only four opportunities to revoke the agreement, and each requires evidence; the one-year statute of limitations for revocation never waits for anyone. If you discover that assets were concealed, check the transaction records first before discussing revocation or supplementary division; if you feel you've been unfairly treated, first check whether there were any genuine defects in the agreement at the time - if not, the agreement is final.

VI. Frequently Asked Questions

Q1: After signing the inheritance division agreement, if I feel that I've been taken advantage of, can I change my mind and withdraw from the agreement?

You can't just regret it because of the "unfair distribution"; the inheritance share could have been negotiated. Unless it can be proven that there was fraud, coercion, significant misunderstanding, or manifestly unfairness, the agreement is binding on all signatories.

Q2: What should I do if the other party concealed their savings when signing the agreement?

The undisclosed deposits belong to omitted assets, and the party concerned may claim for the redistribution of these assets. If the concealment of the deposits is sufficient to affect the true meaning of the overall agreement, the party may also request the revocation of the agreement.

Q3: Is there a time limit for changing one's mind?

Yes. The right of revocation shall be exercised within one year from the date when the party knows or should have known the grounds for revocation (ninety days for major misunderstandings), and the right shall be extinguished upon the expiration of the exclusionary period.

Q4: What should I do if I missed an heir when signing the agreement?

The agreement does not need to be overturned entirely. The inheritance shares of the omitted heirs should be separated from the estate, and the arrangements already made within their shares should be adjusted accordingly.

Q5: Can "signing the contract without reading it carefully" constitute a reason for regret?

Generally, this is not possible. Adults have a duty of care when signing documents. Unless they can prove that there is a significant misunderstanding of the core content of the agreement and have evidence to support it, signing the document means they are bound by its terms.
