Various circumstances may prompt heirs or third parties to challenge an inheritance, from overlooked beneficiaries to errors in asset valuation or unfair divisions. As seasoned estate law experts, we emphasize that contesting a succession is a strictly regulated process designed to honor the deceased's intentions while protecting legitimate rights.
While many estate divisions proceed smoothly, some heirs feel shortchanged by their allocated share compared to others. In such cases, challenging the inheritance is possible—but only with compelling, legally recognized grounds.
French law permits disputes under three primary conditions:
1. The heir was unable to consent freely due to duress (physical or moral pressure), fraud by other heirs, or significant error in the division;
2. An heir was omitted from the division, intentionally or not. Per Article 887-1 of the Civil Code: “The partition can also be canceled if one of the co-heirs has been omitted. The omitted heir may however request to receive his share, either in kind or in value, without cancellation of the partition. To determine this share, the property and rights to which the partition already carried out is reassessed in the same way as if it were a new partition.”;
3. The estate's assets were undervalued, or the distribution contained mathematical errors, resulting in a 'lesionary' (unfair) partition.
Third parties, such as creditors, may also challenge under specific conditions.
To safeguard the deceased's wishes, challenges must be filed in the judicial court at their last domicile. Heirs have two main options: nullity action or additional partition action.
This seeks to annul the division for violence, fraud, error, or omission (Article 887, Civil Code). It must be filed within 5 years of the division. Courts require a lawyer, making it costly and time-intensive. However, judges may opt for a corrective 'additional partition' instead of full annulment.
Available within 2 years of division, this addresses inequalities exceeding one-quarter of an heir's share. The challenger must prove the disparity before a judge, ideally with legal representation.
Creditors of an heir can file an 'objection to sharing' to prevent fraud. They may then pursue an 'oblique action' (nullity or additional partition on the debtor's behalf) or a 'Paulian action'.
