Donation to the last living person: usefulness and limits in 2026

Updated March 29, 2026 - The donation to the surviving spouse (in French, donation au dernier vivant or donation entre époux) is a notarial deed that strengthens the protection of a surviving partner at the time of succession. It does not replace a matrimonial régime, a will, or a comprehensive estate strategy—but it offers considerably more flexibility than the default statutory rules. Understanding exactly what it does, and when it needs to be reviewed, is essential for any owner with family or business assets to protect.

The donation to the surviving spouse widens the rights of the surviving partner at the death of one of them. In practice, it opens up more options within the estate, particularly when the couple has children together. It should be reviewed with a notary whenever the family, professional, or financial situation changes significantly.

The essential point to retain is this: the donation to the surviving spouse does not create new wealth. It modifiés the options available to the surviving partner at the time of succession.

Depending on family circumstances, it can enable the surviving spouse to receive a larger share, or to opt for a more protective combination of rights. Service-Public highlights that in families with children in common, the surviving spouse can benefit from broader options than those offered by the statutory régime alone.

In practice, the aim is twofold:

• preserve the surviving spouse's standard of living;
• prevent an estate from being too rigid when faced with real cash, housing, or business transfer needs.

The donation to the surviving spouse is useful in several contexts:

• the couple wants to protect the survivor without completely blocking the transfer of assets to their children;
• the estate includes significant real property;
• part of the wealth is professional in nature;
• one spouse holds company shares, a holding company, or a sole-trader business;
• the family is blended and the succession picture needs to be clarified.

In business owner files, we rarely handle this instrument in isolation. It is typically combined with the matrimonial régime, the Dutreil pact, beneficiary designations, and sometimes a more detailed will.

Without going into overly technical detail, the donation to the surviving spouse can give the surviving partner more room to maneuver over how assets are distributed.

Depending on the family structure, the notary can explain the relevant options between:

• usufruct (right of use and enjoyment without full ownership);
• full ownership of a larger or smaller share;
• combinations that mix spousal protection with preservation of the children's rights.

The essential principle is not to think only in terms of "statutory share" but in terms of life objectives: housing for the survivor, maintenance of lifestyle, continuation of business activity, balance between children's interests and the survivor's protection.

The donation to the surviving spouse is not a document signed once and then forgotten. It must be reviewed whenever an event changes the family or financial balance.

Typical triggers include:

• marriage or remarriage;
• divorce or séparation of assets;
• birth of a child;
• family recomposition;
• creation or transfer of a business;
• acquisition of significant property;
• retirement.

A deed perfectly suited at age 40 can become inappropriate at 55. That is why we treat it as a living instrument, not a static document.

The errors we encounter most frequently are:

• assuming the donation to the surviving spouse resolves everything;
• not coordinating it with the matrimonial régime;
• forgetting children from a previous relationship;
• failing to account for the impact of a business asset or holding company;
• not revisiting it after a significant change in circumstances.

Hayot Expertise Advice: the donation to the surviving spouse is useful when it forms part of a coherent strategy. In isolation, it can create a false sense of security.

For business owners, the issue is not only family-related—it is also structural. If the estate includes shares, holding company interests, or a sole-trader business, succession can quickly become technically complex.

In that case, the analysis must cover:

• the form of shareholding;
• the existence of a Dutreil pact;
• the survivor's cash needs;
• the heirs' ability to take over or retain the asset;
• the matrimonial régime clauses and any other donations already in place.

The donation to the surviving spouse is a sound protection tool, but it must be articulated with the business transfer strategy—not simply placed alongside it.

Before treating your donation to the surviving spouse as current, check the following points:

1. is the matrimonial régime still suited to the current family situation?
2. has there been a marriage, divorce, birth, or family recomposition?
3. are there children in common and/or children from previous relationships?
4. do you hold professional assets or company shares?
5. has your notary reviewed the whole arrangement against your protection objectives?

In 2026, the donation to the surviving spouse remains a relevant instrument for protecting a partner, but it must be reviewed whenever the family or financial situation changes. Its real value does not lie in the document itself—it lies in the coherence of the whole picture: matrimonial régime, estate assets, business interests, and family objectives.
