Many British owners of a house or flat in France reach the same point. The children are grown up, the French home is the family’s anchor, and waiting for a succession feels like leaving a problem for later. Giving the property now, while you are alive, can look like the generous and tidy solution. Under French law it is a serious legal operation with strict formalities, a protected share for children that limits what you can give away, and a gift tax that can reach 45 percent before allowances. Brexit does not exempt you from any of this. Whether you live in France full time or fly in from the United Kingdom for the holidays, a French house given to your children is taxed in France, must pass through a French notaire, and will be re-examined when your succession opens.

This guide is written for a British reader and explains every French term the first time it appears. A donation is a lifetime gift made by deed. The person who gives is the donateur, the donor. The person who receives is the donataire, the recipient. The notaire is the French public officer who draws up authentic deeds for property transfers. The réserve héréditaire is the forced share of the estate that the law reserves for children. The quotité disponible is the freely disposable share, the part you may give to anyone. With those definitions in place, this article covers the deed that makes the gift valid, the fairness rules between children, the exact calculation of the tax with worked examples, the fifteen-year rule that brings old gifts back into the bill, the British Inheritance Tax overlay, and the practical steps for checking or challenging an assessment you believe is wrong.

I. How to gift a French house to your children while you are still alive

A. Why giving a French home needs a notaire and a formal deed after Brexit

A French house is an immeuble, immovable property, and French law treats gifts of buildings with far more suspicion than gifts of money. A cash transfer between bank accounts can sometimes be a valid manual gift completed by simple delivery. A house can never change hands that way. The gift must be recorded in an authentic deed drawn up by a notaire, and the deed must then be registered so that the change of ownership is effective against everyone, including future buyers, creditors and the tax administration.

The starting point is the legal definition of a lifetime gift. Article 894 of the French Civil Code states: “La donation entre vifs est un acte par lequel le donateur se dépouille actuellement et irrévocablement de la chose donnée en faveur du donataire qui l’accepte.” In plain English, you must part with the property immediately and irrevocably, and your child must accept it. A vague promise to leave the house to a child one day is not a gift. An arrangement where you keep full control and can take the house back at will is not a gift either. The official text is published in the French Civil Code, Article 894.

The form is just as strict as the substance. Article 931 of the Civil Code provides: “Tous actes portant donation entre vifs seront passés devant notaires dans la forme ordinaire des contrats ; et il en restera minute, sous peine de nullité.” Every deed of lifetime gift must therefore be executed before a notaire, who keeps the original, on pain of nullity. A private agreement signed at the kitchen table, an English-language letter of wishes, and even a solicitor’s deed drawn up only under English law cannot transfer a French house. The consequence of ignoring this rule is severe: the gift is void, the property legally never left your estate, and your children would have to start again from scratch. The official text is available in the French Civil Code, Article 931.

British owners sometimes ask whether their United Kingdom will can do the same job more cheaply. A will only takes effect on death, so it cannot replace a lifetime gift, and since Brexit an English will covering French land still needs careful coordination with French forced-heirship rules and French notarial procedure. Those questions are examined in our analysis of what happens when a British resident dies in France with a UK will. For a transfer during your lifetime, the notarial deed is unavoidable, and you should budget for the notaire’s fees and registration duties on top of the gift tax itself.

In practice the file runs as follows. First, the notaire checks your title deeds, the absence of undisclosed mortgages or charges, the planning position of the property, and the identity and capacity of everyone involved. If you are married, the notaire will examine your matrimonial property regime, because a house bought during the marriage may belong to both spouses and both must then join in the gift. Second, the notaire has the property valued at its open market value on the day of the gift, the valeur vénale. This valuation is the foundation of the whole tax calculation, so it deserves real attention: an inflated valuation means overpaid tax, and an understated one invites a reassessment. Third, the deed is signed, the recipient accepts expressly, and the notaire registers the transfer and files the gift tax return with the French tax administration. Keep every document indefinitely: the deed, the valuation report, proof of payment of the tax, and evidence of any earlier gifts. You will need them again when your succession opens, and your children will need them if the assessment is ever questioned.

One Brexit-specific warning matters here. Some British owners assume that because the United Kingdom has left the European Union, French formalities somehow apply less strictly to them, or that an English-law trust or family arrangement can bypass the notaire. It cannot. French land is governed by French law for transfers of ownership, regardless of your nationality or residence. Structures valid in England, such as holding the house through informal family understandings, have no equivalent effect in France and can create expensive confusion at the land registry and at the tax office.

B. How to keep the gift fair between children and inside the forced share

French law does not let you give your house to one child and leave the others with nothing. Children are héritiers réservataires, forced heirs, and the law reserves them a minimum share of your estate. Gifts made during your lifetime count towards that calculation when you die. A gift that was perfectly valid on the day it was signed can therefore be partly clawed back years later if it turns out to have eaten into a sibling’s forced share. Planning the gift properly at the outset is far cheaper than litigating the succession afterwards.

The scale of the forced share is fixed by Article 913 of the Civil Code: “Les libéralités, soit par actes entre vifs, soit par testament, ne pourront excéder la moitié des biens du disposant, s’il ne laisse à son décès qu’un enfant ; le tiers, s’il laisse deux enfants ; le quart, s’il en laisse trois ou un plus grand nombre.” With one child, half of your estate is reserved and half is freely disposable. With two children, two thirds are reserved and one third is free. With three or more children, three quarters are reserved and only one quarter is free. Everything you give away during your life, including the French house, is added back into a fictional total at your death to check whether any child received less than the forced share. The official text is in the French Civil Code, Article 913.

The same article contains a provision that British families should read carefully. Where the deceased or at least one of the children is a national of a European Union Member State or habitually resident there, and the foreign law governing the succession offers children no forced-share protection, the text provides a compensatory levy allowing each child to take from property situated in France at the date of death, so as to recover the forced-share rights granted by French law within their limits English law gives children no forced share, so a British family might assume this mechanism automatically protects children from disinheritance under an English will. Since Brexit, however, British nationality alone is no longer the nationality of a Member State. The provision can still help where the deceased or a child is habitually resident in France, which is an EU Member State, but the analysis is now genuinely delicate and must be checked file by file rather than assumed. Do not rely on general statements found online; ask your notaire or lawyer to confirm how the rule applies to your family’s nationalities and residences.

The cleanest instrument for fairness is the donation-partage, the gift-sharing deed. Article 1075 of the Civil Code states: “Toute personne peut faire, entre ses héritiers présomptifs, la distribution et le partage de ses biens et de ses droits. Cet acte peut se faire sous forme de donation-partage ou de testament-partage. Il est soumis aux formalités, conditions et règles prescrites pour les donations entre vifs dans le premier cas et pour les testaments dans le second.” In practice, both parents and all the children attend before the notaire, the French house is divided into lots of equal value, or given to one child with compensating payments to the others, and everyone accepts. The great advantage is stability: values are frozen at the day of the deed for the forced-share calculation, so a later rise in French property prices does not reopen the quarrel. The official text is published in the French Civil Code, Article 1075.

Where no gift-sharing deed was made, an over-generous gift can be attacked after death through the action en réduction, the court claim for reduction of excessive gifts. The French Court of Cassation confirmed the nature and time limit of this claim in its First Civil Chamber judgment of 23 October 2024, appeal number 22-19.365. The Court held that the reduction claim granted to forced heirs is a personal action subject to the five-year limitation period, even where it affects rights in given or bequeathed property. In short, the disadvantaged child now generally has five years to bring the claim. For successions opened before 1 January 2007, the same judgment recalled that the previous thirty-year period running from the opening of the succession applied. The full official decision, ECLI:FR:CCASS:2024:C100578, is available from the Court’s open-data service at Cour de cassation, First Civil Chamber, 23 October 2024, no. 22-19.365.

The lesson for British donors is practical. If you have two or three children and give the French house to only one of them, the others may sue for reduction after your death, and the house itself can be affected. Either divide the property fairly in a gift-sharing deed now, or keep the gift inside the freely disposable share and document the calculation. Tell the notaire about every earlier gift, including cash gifts made in the United Kingdom, because they all count in the final reckoning at death.

II. How much French gift tax your children will pay and how to cut the bill

A. How the 100,000 euro allowance and the sliding scale work on a French home

France taxes the gift of a French house even where the donor lives in the United Kingdom and the children live there too. The territoriality rule is set by Article 750 ter of the General Tax Code, which opens with the words: “Sont soumis aux droits de mutation à titre gratuit :” It then distinguishes two situations. Where the donor is fiscally resident in France, the French rules can catch property inside and outside France. Where the donor is not resident in France, France still taxes movable and immovable property situated in France. A house in the Dordogne, a flat in Paris or a villa on the Riviera therefore falls inside the French gift-tax net whoever gives it and wherever the family lives. The full official text is in Article 750 ter of the Code général des impôts.

The good news is the parent-to-child allowance. Article 779 of the General Tax Code provides that “il est effectué un abattement de 100 000 € sur la part de chacun des ascendants et sur la part de chacun des enfants vivants ou représentés par suite de prédécès ou de renonciation.” Each child therefore receives the French home with the first 100,000 euros of their share completely free of gift tax, and the allowance is personal to each child. With three children sharing a house, 300,000 euros escapes tax before the scale even starts. The official text is published in Article 779 of the Code général des impôts.

Above the allowance, the progressive scale in Article 777 applies to each child’s net taxable share. For gifts in the direct line between parents and children, the table reads: 5 percent on the fraction not exceeding 8,072 euros, 10 percent between 8,072 and 12,109 euros, 15 percent between 12,109 and 15,932 euros, 20 percent between 15,932 and 552,324 euros, 30 percent between 552,324 and 902,838 euros, 40 percent between 902,838 and 1,805,677 euros, and 45 percent beyond 1,805,677 euros. The complete official scale, including the tables for spouses, siblings and unrelated recipients, is set out in Article 777 of the Code général des impôts.

Two worked examples show why dividing the gift matters. Take a French house worth 400,000 euros given outright to an only child. Subtract the 100,000 euro allowance, leaving 300,000 euros taxable. The bill is 403.60 euros on the first band, 403.70 euros on the second, 573.45 euros on the third, and 56,813.60 euros at 20 percent on the remaining 284,068 euros, a total of about 58,194 euros. Now take the same house shared equally between two children in a gift-sharing deed. Each child receives 200,000 euros, subtracts a personal 100,000 euro allowance, and pays tax on 100,000 euros: 403.60 plus 403.70 plus 573.45 plus 16,813.60 euros at 20 percent on the remaining 84,068 euros, about 18,194 euros each. The family total falls from roughly 58,194 euros to roughly 36,389 euros, a saving of more than 21,000 euros achieved simply by using both allowances and keeping more of the value in the lower bands. These figures ignore notaire fees and registration duties, which come on top, but they show the mechanics clearly.

Three practical points complete the picture. First, the valuation date is the day of the deed, so in a rising market an early gift freezes the taxable value at today’s price. Second, the allowance belongs to each parent separately: where both parents join in the gift, each child can receive 100,000 euros from each parent, doubling the shelter. Third, gifts between spouses and civil partners use a different table with wider low-rate bands, which can matter where the house is first reorganised between the parents before being passed down. Each of these steps must be documented in the deed, because the tax administration will check the arithmetic against the registered value.

B. When an old gift comes back into the calculation and how to challenge the tax bill

A French gift-tax bill is never calculated on the new gift alone. Earlier gifts from the same donor to the same child are added back to push the new transfer into higher bands, unless enough time has passed. Article 784 of the General Tax Code states the rule: “La perception est effectuée en ajoutant à la valeur des biens compris dans la donation ou la déclaration de succession celle des biens qui ont fait l’objet de donations antérieures, à l’exception de celles passées depuis plus de quinze ans, et, lorsqu’il y a lieu à application d’un tarif progressif, en considérant ceux de ces biens dont la transmission n’a pas encore été assujettie au droit de mutation à titre gratuit comme inclus dans les tranches les plus élevées de l’actif imposable.” Gifts made more than fifteen years ago drop out of the calculation entirely, and the related allowances are refreshed. The same article requires the parties to declare in every deed whether earlier gifts exist, their amounts, and the notaires who received them. The official text is in Article 784 of the Code général des impôts.

This fifteen-year memory has sharp consequences for British families. A cash gift made ten years ago to help a child through university, even if it was declared and taxed at the time, will be added to the value of the French house given today and can push the house into the 20 or 30 percent bands. Conversely, if the last gift dates back sixteen years, the clock has reset and the full allowance and the lowest bands apply again. Families sometimes time a large gift to fall just after the fifteen-year anniversary of the previous one. Whatever your timing, never hide an earlier gift from the notaire: concealment exposes the file to reassessment, interest and penalties, while a correctly declared old gift that falls outside the fifteen years costs you nothing.

The British side of the picture runs on a different clock. Under United Kingdom Inheritance Tax rules, lifetime gifts can be taken into account if the donor dies within seven years. The official GOV.UK guidance states: Lifetime gifts can attract Inheritance Tax if the donor dies within seven years, with the treatment depending on the recipient, the value and the timing of each gift. See GOV.UK, Rules on giving gifts. A British donor must therefore think in two timeframes at once: fifteen years for the French calculation, seven years for the British one. The two systems do not cancel each other out, and their interaction depends on domicile, residence, available reliefs and the precise characterisation of each transfer. Take advice in both countries before signing, keep both tax assessments and both sets of payment receipts, and make sure each adviser sees the other country’s paperwork.

If the French assessment looks wrong, work through the file methodically before paying under protest or filing a formal claim. First, check the valuation: is the valeur vénale in the deed supported by comparable sales, and does it reflect any genuine discount such as an existing tenancy or disrepair. Second, check the allowances: has each child’s 100,000 euro allowance been applied, has each parent’s separate allowance been used where both parents gave, and has the sibling allowance been confused with the parent-to-child one. Third, check the fifteen-year history: has an old gift from more than fifteen years ago been wrongly added back, or has a gift that was already taxed been counted twice. Fourth, check for clerical errors in names, shares, dates and band arithmetic, which happen more often than anyone admits. Ask the notaire for the full tax computation, the décompte, and compare every line against the deed and the articles cited in this guide.

Where an error is confirmed, raise it first with the notaire, who can correct a material mistake or contact the tax office, and then through the formal complaint routes shown on the assessment notice itself, keeping copies of everything and watching the time limits printed on the notice. Act quickly: French tax claims are subject to strict deadlines, and a late challenge can fail whatever its merits. If the property was overvalued, commission an independent valuation from a qualified local agent or surveyor to support your case. If the dispute concerns the characterisation of an old transfer, for example whether money sent years ago was a genuine repayable family loan or a gift, gather the bank records and any written loan terms now, because a repayment story invented after the enquiry carries no weight. Throughout, keep paying what is indisputably due where possible, so that interest stops running on the uncontested part while the disputed balance is argued.

Conclusion

Giving your French home to your children during your lifetime is one of the most effective succession plans a British owner can make, provided it is done the French way. Use a notarial deed, because nothing else transfers a French house. Divide fairly through a gift-sharing deed where there are several children, because the forced share will catch up with an unbalanced gift at death. Claim each child’s 100,000 euro allowance, use both parents’ allowances where possible, mind the fifteen-year memory of earlier gifts, and remember the separate seven-year British clock. Check the valuation, the allowances and the arithmetic before accepting any bill, and challenge errors promptly with evidence. Done properly, a lifetime gift freezes values, uses allowances that a will cannot multiply, and spares your children the worst of the paperwork. Done informally, it achieves nothing and can cost the family twice. The files that succeed are the ones where the notaire knew the full history, both countries’ clocks were considered, and every figure was checked against the official texts.
