Contesting a Will or an Unfair Share: French Inheritance Disputes

When you can challenge a French inheritance

You can challenge a French inheritance in three broad situations: where you have been left less than the share French law reserves for you, where the will itself is invalid, or where another heir has concealed assets or gifts to tilt the division in their favour. Each situation has its own legal mechanism, its own claimant, and its own time limit, and the right one depends on what actually went wrong. A French estate is not a matter of free testamentary choice in the way common-law estates are: the Civil Code fixes who must inherit and how much, and those rules are enforceable in court by the people they protect.

The reason disputes arise so often is that French succession law overrides the deceased's wishes in ways foreign families rarely expect. Children — and, where there are no children, a surviving spouse — are reserved heirs whose minimum share cannot be given away, and a gift or a will that ignores them does not fail automatically. It stands until a protected heir attacks it. The same is true of lifetime gifts that were supposed to be accounted for on death, and of a will drawn up by someone whose mind was failing. Nothing in French law reverses these things on its own; the burden is on the person who has been shortchanged to bring the correct action, in time, before the right court.

This article sets out when and how you can contest a French inheritance. It explains how a reserved heir recovers a share that has been given away through the action to reduce, how a will can be attacked for lack of mental capacity or for a formal defect, what happens when an heir hides assets (recel successoral), how lifetime gifts must be brought back into account through the report (le rapport), the time limits that govern each claim, and how the process actually works — from the notaire who settles the estate to the court that resolves the fight. The mechanisms overlap, and a single dispute often involves more than one of them at once.

Recovering your reserved share (the action en réduction)

If gifts made during the deceased's lifetime or legacies in the will have eaten into the share French law reserves for you, you recover it by the action to reduce (action en réduction): excessive gifts and legacies are reducible to the freely disposable portion when the succession opens (Article 920 of the Civil Code). The action does not cancel the gift for everyone — it restores to the reserved heir the value of what should have come to them. It is the single most important tool for a child or a childless spouse who has been cut out or under-provided for.

The foundation is forced heirship. French law guarantees the reserved heirs — the descendants, and where there are none the non-divorced spouse — a fixed share of the estate, the reserved portion (réserve héréditaire), leaving only the freely disposable portion (quotité disponible) that can be given to others. With one child, half the estate is reserved; with two children, two thirds; with three or more, three quarters (Article 913 of the Civil Code). A childless spouse is a reserved heir for one quarter (Article 914-1). Anything the deceased gave away — by will or by lifetime gift — that trespasses on the reserve is, in principle, reducible.

Two features of the action catch heirs out. The first is that it is not automatic. Reduction does not operate by law: it must be claimed by the reserved heirs, and by them alone (Articles 920 and 921 of the Civil Code). If no one asks, an excessive gift stands, and the tax authority itself cannot reduce a gift of its own motion — it must follow what the parties declare (a point the courts have confirmed: the demand is subject to no particular formality, Cour de cassation, first civil chamber, 10 January 2018, no. 16-27894). Only the reserved heirs, their own heirs, their assignees and their personal creditors acting on their behalf may invoke it; non-reserved heirs, donees and legatees cannot.

The second feature is that reduction is worked out in a strict order. The Civil Code fixes the sequence in which gifts and legacies are cut back, so that the most recent liberality is reduced first. Legacies are reduced before lifetime gifts, and among gifts the reduction begins with the most recent and works back to the oldest (Article 923 of the Civil Code). The logic is that the deceased's earlier gifts were made when there was still disposable room, and it is the later, over-reaching dispositions that broke the reserve.

Reduction in value, not in kind

When a gift or legacy is reduced, the donee or legatee does not usually have to hand back the asset itself. Reduction now operates in value: the recipient keeps the property and pays the reserved heir a reduction indemnity (indemnité de réduction) equal to the excessive portion of the liberality (Article 924 of the Civil Code). This protects third parties who have since bought the property and avoids forcing the asset into joint ownership. The indemnity is calculated on the value of the property at the date of the division, according to its condition when the gift took effect (Article 924-2), and it is normally payable at the division. Reduction in kind — recovering the asset itself — survives only in narrow cases, such as where the recipient is insolvent (Article 924-4). For the reserved heir, the practical result is a money claim against the person who received too much, not a fight over the physical asset.

Challenging a will's validity

A will can be challenged either because the testator lacked the capacity to make it or because it does not meet the strict formal requirements the Civil Code imposes. Both are grounds of nullity: if the challenge succeeds, the will is treated as if it had never existed, and the estate passes under the previous valid will or, failing that, by the ordinary rules of legal devolution. These are the classic routes for an heir who believes a will does not reflect the deceased's true, free and informed intention.

The first ground goes to the mind of the testator. A will requires a sound, free and informed intention (Articles 901 and 1129 of the Civil Code), and it is open to attack for unsoundness of mind (insanité d'esprit) — a significant impairment of the testator's mental faculties at the time the will was made (Article 901). What matters is the testator's state at the moment of signing, and the challenge succeeds where the impairment is established for that time. Importantly, the existence of a formal protective regime is not decisive either way: the fact that the testator was, or was not, under guardianship does not settle the question, and a will can be annulled for unsoundness of mind even where no protective measure was in place (Cour de cassation, first civil chamber, 27 June 2018, no. 17-20428).

The second ground goes to form. The rules of form for a will are, in the Civil Code's own scheme, essential and mandatory, interpreted restrictively by the courts and imposed on pain of nullity (Article 1001 of the Civil Code). The two ordinary forms have precise requirements. A holographic will (testament olographe) — the home-made will — must, to be valid, be written in full, dated and signed by the testator's own hand, and it is subject to no other form (Article 970). A typed "holographic" will, or one written out by someone else, is void. An authentic will (testament authentique), by contrast, is received by two notaires, or by one notaire assisted by two witnesses (Article 971), and its formalities are strict on pain of nullity (Articles 973 and 1001).

Holographic versus authentic wills, and which is harder to attack

The choice of form shapes how vulnerable a will is. A holographic will is easy to make but easy to attack: a wrong or missing date, a signature that is not in the testator's hand, doubt over the handwriting, all open the door to a nullity claim. An authentic will is far more robust. Because it is a public deed, it carries evidential force: the notaire's own recorded findings stand until the special procedure for challenging a public deed as forged (inscription de faux) is brought, and disinherited heirs find it correspondingly harder to contest (Article 971). This is also why French law makes the authentic form compulsory for certain acts, such as depriving a surviving spouse of the lifetime right of occupation of the home.

A will can also be undone without any defect, simply because the testator changed their mind. A later will revokes an earlier one to the extent the two are inconsistent, and a validly made later will in one form can revoke a will made in another form — a subsequent holographic will deposited with the notaire has been held to validly modify an earlier authentic will (Cour de cassation, first civil chamber, 9 July 2014, no. 13-18685). When several documents surface after a death, establishing which is the last valid expression of the testator's wishes is itself frequently the heart of the dispute.

Concealed assets (recel successoral)

Where an heir hides an estate asset, or conceals the existence of another heir, to break the equality of the division in their own favour, they commit concealment of estate assets (recel successoral) and face heavy, cumulative penalties (Article 778 of the Civil Code). This is French law's answer to the co-heir who empties a bank account, suppresses a will, hides a lifetime gift they received, or keeps quiet about a half-sibling who ought to share the estate. It is one of the most powerful weapons an honest heir has, precisely because the sanctions are punitive rather than merely compensatory.

The offence has two elements: a material act and a fraudulent intent. The material element can take many forms — abstracting an asset that belongs to the estate, failing to reveal estate property in one's possession at an inventory, concealing the existence of a co-heir, hiding or faking a will, or hiding a gift the heir had received, such as a prior undeclared hand-to-hand gift (don manuel). The intentional element is the intention to appropriate estate assets behind the other heirs' backs and to their detriment, and the wronged heirs bear the burden of proving that fraudulent intent, which the trial judges assess (Cour de cassation, first civil chamber, 27 January 1987, no. 85-15336). Concealment covers all the frauds by which an heir seeks, at the expense of the others, to break the equality of the division (Cour de cassation, first civil chamber, 7 December 1982, no. 81-1547).

The sanctions apply in three ways at once. First, the concealing heir is deemed to accept the estate purely and simply, whatever renunciation or limited acceptance they had made — which means they are liable for the estate's debts without limit (Article 778). Second, and most striking, they cannot claim any share whatever in the assets they concealed: those assets go to the other heirs, and the concealer is excluded from them entirely, while still having to restore them (Article 778). Third, they must return the fruits and income the concealed assets produced from the opening of the estate, and can be ordered to pay damages on top (Article 778, paragraphs 1 and 3).

Two limits are worth knowing. Concealment presupposes a reserved heir to protect: hiding the deceased's gifts to a universal legatee cannot be treated as recel where there is no reserved heir, because such a gift is neither reportable nor reducible (Cour de cassation, first civil chamber, 20 October 2010, no. 09-16157). And where the concealment relates to a reportable or reducible gift, the concealing heir owes the report or the reduction of that gift without being able to claim any part of it (Article 778, paragraph 2). A related fraud is punished the same way: heirs who knowingly and in bad faith rely on an inaccurate deed of known heirs (acte de notoriété) — the notarial deed that establishes who the heirs are — incur the penalties laid down for concealment, plus damages (Article 730-5 of the Civil Code).

Reporting lifetime gifts (le rapport)

Separately from any claim to reduce excessive gifts, French law requires most lifetime gifts to be brought back into account on death so that the children share equally. This is the report of gifts (le rapport): every heir coming to a succession must report to their co-heirs everything they received from the deceased by gift or will (Article 843 of the Civil Code). It is not a penalty — it is an equalising step taken before the division, on the assumption that a gift to a future heir was an advance on their inheritance, not an extra on top of it.

The starting point is a presumption. Gifts to an heir are presumed reportable unless they were expressly made "outside the estate share" (hors part successorale); legacies to an heir, by contrast, are presumed to be outside the share unless the will says otherwise (Article 843, paragraphs 1 and 2). A reportable gift is therefore treated as an advance on the heir's portion (en avancement d'hoirie): its value is added back to the estate, the shares are worked out on the enlarged total, and the heir who received the gift takes correspondingly less from what remains. The disposer alone can defeat the report, by expressly stipulating that the gift is made outside the share to favour that heir definitively (Article 843).

How the report is valued matters as much as whether it is due. The report is owed of the value of the gifted asset at the time of the division, according to its condition at the day of the gift (Article 860 of the Civil Code) — so an heir who received a house that has since risen in value reports the higher, present-day figure, not the sum the property was once worth. A gift of money is reported at its face amount, unless it was used to acquire an asset, in which case the value of that asset governs (Article 860-1). Only gifts received from this deceased are reportable, because the report is made solely to the donor's own estate (Article 860).

The report and the action to reduce are often confused, but they do different work. The report equalises the children's shares and gives effect to what the parent is presumed to have wanted; the reduction protects the reserved portion and can defeat what the parent wanted. Their valuation rules differ, and a single gift can be both reportable and reducible at once. For an heir who suspects a sibling was quietly advantaged during the parent's life, the report is the mechanism that forces the gift onto the table; the reduction is what recovers the reserve if the gift also went too far.

Time limits

Every route to contesting a French inheritance is time-barred, and the clock on the most important one — the action to reduce — is unforgiving. The action to reduce is prescribed by five years from the opening of the succession, or by two years from the day the heirs became aware of the encroachment on their reserve, without ever being able to exceed ten years from the death (Article 921 of the Civil Code). In plain terms: you have five years from the death as of right; if you only discover the problem later, you get two years from that discovery; and in no case more than ten years from the death overall.

That two-year discovery rule is what saves heirs who learn late — for instance, that a large gift had been made years earlier, or that the estate had been quietly depleted. But the ten-year long-stop is absolute, and it is measured from the death, not from discovery. Where the gift was of jointly-owned (community) property, the courts have refined the starting point: the five-year period for the reduction runs, as to half the gift, from the death of the first spouse, and as to the other half, from the death of the second (Cour de cassation, first civil chamber, 5 January 2023, no. 21-13151).

The other claims run on different clocks, and it is worth separating them:

Concealment is treated differently because it is raised inside the settlement of the estate rather than as a stand-alone action with its own short prescription. Where the concealment relates to a reportable or reducible gift, the demand for the report of that gift must be made in the course of proceedings for the division of the estate (Cour de cassation, first civil chamber, 2 September 2020, no. 19-15955). The practical lesson is the same across all of these: an heir who suspects a problem should take advice quickly, because the shortest and most valuable claims run out first, and the option to accept or renounce the estate itself lapses ten years after the death (Article 780 of the Civil Code).

How the process works

A French inheritance dispute plays out against the ordinary settlement of the estate, which the notaire runs. The notaire is not a judge and does not decide contested rights, but the notaire's work — identifying the heirs, valuing the estate and reconstituting the lifetime gifts — is what surfaces the problem and frames the fight. Where the heirs cannot agree, the dispute leaves the notaire's office and goes to the civil court. Understanding the sequence tells you where and when each claim has to be made.

Because the claims are settled inside the division, timing and evidence are everything. The reserved heir has to raise the reduction within the Article 921 periods; the challenger of a will has to gather the medical and handwriting evidence that proves unsoundness of mind or a formal defect; and the heir alleging concealment must prove the other's fraudulent intent, which the trial judges assess on the facts (Cour de cassation, first civil chamber, 27 January 1987, no. 85-15336). A well-run claim is prepared before the notaire closes the account, not after — which is why the point to take advice is early, while the estate is still open.

Frequently asked questions about French inheritance disputes

Can I contest a will in France?

Yes, on two main grounds. You can attack the will's validity — for unsoundness of mind at the time of signing (Article 901 of the Civil Code) or for a formal defect, such as a holographic will that is not entirely handwritten, dated and signed (Article 970), or an authentic will that does not meet the requirements of Article 971. Separately, even a valid will cannot override your reserved share as a child or childless spouse, and gifts or legacies that encroach on it can be cut back by the action to reduce (Article 920).

How do I recover my reserved share?

By bringing the action to reduce (action en réduction): excessive gifts and legacies are reducible to the freely disposable portion, restoring your reserve (Article 920 of the Civil Code). It is not automatic — you must claim it, as only the reserved heirs can (Article 921). Reduction is generally in value, so the recipient keeps the asset and pays you a reduction indemnity equal to the excessive portion (Article 924), rather than handing the property back.

What is recel successoral?

It is the concealment of estate assets: an heir who hides an asset, suppresses or fakes a will, hides a gift they received, or conceals another heir, in order to break the equality of the division (Article 778 of the Civil Code). The penalties are cumulative and severe — the concealer is forced to accept the estate outright and its debts without limit, loses any share in the concealed assets, and must restore them together with the income they produced (Article 778).

How long do I have to challenge?

For the action to reduce, five years from the opening of the succession, or two years from the day you learned of the encroachment on your reserve, and in no event more than ten years from the death (Article 921 of the Civil Code). Concealment is raised within the division proceedings while the estate is unsettled (Article 778; Cour de cassation, first civil chamber, 2 September 2020, no. 19-15955), and the option to accept or renounce the estate itself lapses ten years after the death (Article 780).

On what grounds is a will invalid?

Chiefly two. First, lack of capacity: a will requires a sound, free and informed intention, and can be annulled for unsoundness of mind (Article 901 of the Civil Code) — the existence or absence of a protective regime is not decisive (Cour de cassation, first civil chamber, 27 June 2018, no. 17-20428). Second, a formal defect: the rules of form are mandatory on pain of nullity (Article 1001), so a holographic will must be wholly handwritten, dated and signed (Article 970), and an authentic will received by two notaires, or one notaire and two witnesses (Article 971).

Can I be disinherited by a French will?

Not if you are a reserved heir. Children cannot be cut out: half the estate is reserved for one child, two thirds for two, and three quarters for three or more (Article 913 of the Civil Code), and a childless spouse is reserved one quarter (Article 914-1). A will that ignores the reserve does not fail on its own, but the reserved heir can recover their share through the action to reduce (Article 920). Only where there are no reserved heirs at all is the whole estate freely disposable (Article 916).

What happens if an heir hides a lifetime gift?

If the hidden gift was reportable or reducible, the concealing heir owes the report or the reduction of that gift and cannot claim any part of it (Article 778, paragraph 2, of the Civil Code). More broadly, lifetime gifts to an heir are presumed to be advances on their share and must be brought back into account on death (le rapport) unless expressly made outside the share (Article 843), valued at the time of the division according to their condition at the day of the gift (Article 860).

How our French lawyers help with French inheritance disputes

Inheritance disputes in France turn on getting the right claim, in the right forum, before the clock runs out — and the deadlines are short. We advise heirs and beneficiaries on whether you have been left less than your reserved share and how to recover it through the action to reduce, on whether a will can be attacked for lack of capacity or a formal defect, and on whether an heir has concealed assets or gifts that trigger the penalties for recel successoral. We work alongside the notaire settling the estate and, where the family cannot agree, take the matter through the judicial court and the court-supervised division, building the evidence — medical records, handwriting, gift histories, bank movements — that these claims stand or fall on.

This article is for general information only. It does not constitute legal advice and does not create a lawyer-client relationship. Whether and how a French inheritance can be contested depends on the family, the assets, the will, the gifts made, and the time that has passed since the death.
