[Direct answer]There are three differences. Firstly, the circumstances are different: invalid marriages are limited to three situations: bigamy, kinship relations prohibiting marriage, and not reaching the legal age for marriage (Article 1051 of the Civil Code); revocable marriages are limited to two situations: marriage by coercion and concealment of major diseases before marriage. Secondly, the subjects of claims and the statute of limitations are different: invalid marriages do not change with the passage of time, and the court can determine them ex officio; revocable marriages require the injured party to file a claim with the court within the statutory time limit (generally one year), and the right to revoke the marriage will be extinguished if the time limit is exceeded. Thirdly, the starting point of legal effect is different: invalid marriages are not legally binding from the beginning; revocable marriages are valid before being revoked, and become invalid from the moment of revocation.

1. Problem background and typical scenarios

When there are disputes over the validity of a marriage, parties often confuse two concepts: some argue that "our marriage is completely invalid," but the actual situation can only be revoked; others believe that if the other party conceals a disease, the marriage is automatically invalid, ignoring the requirement to file a lawsuit within one year. If the concept is used incorrectly, the litigation request will be chosen incorrectly, and the procedural, burden of proof, and time limit requirements will also vary accordingly, ultimately affecting the handling of property and identity relations.

II. Key points of contention

1. A comprehensive enumeration and understanding of invalid situations. 2. The scope of revocable situations and the entities entitled to claim. 3. Differences in time limits and calculation rules. 4. The handling of assets, children, and damages compensation in the two situations.

III. Professional analysis by Henglue Lawyers

The first layer: Invalid marriages are exhaustively listed. Article 1051 of the Civil Code only stipulates that marriages involving bigamy, kinship relationships prohibited by law, and those below the legal age of marriage are invalid, and cannot be arbitrarily expanded. It's worth noting that in the case of marriages involving minors, if both parties have reached the legal age of marriage by the time of litigation, the grounds for invalidation have been eliminated, and the court will no longer deem them invalid. The second layer: There are two grounds for revoking a marriage: one is marriage by coercion, and the other is concealment of a major disease before marriage. Both require the aggrieved party to actively request the court to revoke the marriage, and are subject to a one-year statute of limitations. The statute of limitations for coercion begins from the date the coercive act ceases, and for concealment of disease, it begins from the date the party knows or should have known. The third layer: There are procedural differences between invalidation and revocation. Invalid marriages can be identified upon the request of the parties, and may also be reviewed by the court ex officio during the trial of other cases, without time restrictions. Revocable marriages strictly depend on the parties' claims and the statute of limitations. The court will not actively initiate revocation on behalf of the parties. The fourth layer: Legal consequences and property disposition: Whether the marriage is invalidated or revoked, the marriage is legally binding from the outset, and the parties do not have the rights and obligations of a married couple. Property acquired during cohabitation is handled by the parties through agreement, and if no agreement is reached, the court will adjudicate based on the principle of protecting the innocent party. In the case of invalid marriages caused by bigamy, the disposition of property must not infringe upon the rights of the parties to a legitimate marriage. Child custody issues are handled in accordance with the relationship between parents and children, and children born out of wedlock enjoy the same rights as those born in wedlock. Henglue Tip: Before requesting revocation or confirmation of invalidity, it's important to clarify the grounds and time limits, and then determine the litigation requests to avoid losing remedial opportunities due to procedural errors.

IV. Practical suggestions and legal basis

First, compare the legal circumstances to determine whether the marriage is invalid or revocable, to avoid confusing the two concepts. Second, if the circumstances are revocable, check whether the one-year statute of limitations has expired and file a lawsuit as soon as possible. Third, if the circumstances are invalid, you can directly request a declaration of invalidity and handle property and child custody issues simultaneously. Fourth, pay attention to protecting the property rights of the innocent party and the legitimate marriage parties. Main legal basis: Articles 1051, 1052, 1053, and 1054 of the Civil Code of the People's Republic of China (effective January 1, 2021), as well as relevant judicial interpretations on marriage and family matters. Specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

Three sentences on invalidity and revocation: There are only three cases of invalidity, namely bigamy, prohibited marriage between relatives, and underage marriage, which are closed situations; there are only two cases of revocability, namely coercion and concealment of major diseases, and the party concerned must actively claim within one year; invalidity is invalid from the beginning, and revocability is valid before revocation.

VI. Frequently Asked Questions

Q1: Is a marriage before the legal age of marriage necessarily invalid?

A marriage that is not registered according to the legal age for marriage is invalid. However, if both parties have reached the legal age for marriage at the time of litigation and the grounds for invalidation have been eliminated, the court will no longer recognize it as an invalid marriage.

Q2: Can one party claim that the marriage is invalid if they have been unfaithful?

No. Infidelity does not constitute a statutory ground for invalidation, nor is it a rescindable cause; it may be a factor to be considered when providing support to the innocent party and compensation for damages in the event of divorce, but it will not render the marriage invalid from the outset.

Q3: Can a revocable marriage be revoked if it has lasted for more than a year?

No. One year is the statute of limitations period, and it does not apply to suspension, interruption, or extension. After the expiration of the statute of limitations, the right of revocation is extinguished, and the marriage becomes valid. It can only be dissolved through divorce litigation.

Q4: How are the assets of an invalid marriage handled?

During the cohabitation, the property acquired by the parties shall be dealt with according to their agreement. If no agreement can be reached, the court shall make a judgment based on the principle of protecting the innocent party. If the marriage is invalid due to bigamy, the property rights and interests of the parties to the legitimate marriage shall not be infringed.

Q5: Is there a time limit for confirming the invalidity of a marriage?

There is generally no time limit. The invalid grounds do not disappear with the passage of time (except for those that have been rectified after reaching the marriageable age), and the parties may request confirmation in accordance with the law. The court may also review it ex officio during the trial.
