Contesting a Will for a Formal Defect: What Heirs Need to Know

Imagine: you live in Colmar, and your father, owner of a house in Thann, has just passed away. Upon opening his will, you discover that he leaves all his assets to a neighbour. You are shocked, because you thought you were the sole heir. But the will seems in order: signed, dated. Yet, a detail catches your eye: the deed was written on a simple loose sheet, without a notary's signature. Is that sufficient? The question every heir asks when faced with a suspicious will: can it be contested? And if so, on what grounds?

This case, decided by the Montpellier Judicial Court on 29 January 2025, provides a clear answer: a will can be contested for a simple formal defect, even if its content is not challenged. In other words, just because the deceased's wishes seem clear does not mean the deed is valid. Compliance with legal formalities is an absolute condition of validity.

In this article, I decode this decision and its practical implications for you. Whether you are an heir, a legatee, or simply curious, you will know what your rights are and how to react when faced with a disputed will.

The Facts: A Story Like Many Others

Mr G., a 78-year-old retiree living in Colmar, wrote a holographic will (handwritten) in 2020. He leaves all his assets, including a house in Thann, to his partner Mrs D. His two children from a first marriage are excluded. Upon his death in 2023, the partner presents the will to the heirs. They note that the document is dated 15 March 2020, but Mr G.'s signature is placed at the top of the page, before the text, and not at the end. Moreover, the usual phrase "read and approved" is missing. For the children, this is a blatant formal defect. They take the matter to the Montpellier Judicial Court (competent because the house is located in its jurisdiction) to seek annulment of the will.

The partner, Mrs D., argues that the will is valid: the deceased clearly expressed his wishes, and the lack of a signature at the bottom is only a minor formality. She produces statements from relatives affirming that Mr G. indeed intended to favour her. But the children maintain their challenge, arguing that the law is strict on this point: without a compliant signature, the will is void.

The case is heard in a public hearing in Montpellier. The judges must decide between the testator's actual wishes and compliance with the forms prescribed by law. After deliberation, they deliver their decision on 29 January 2025. Verdict: the will is annulled for a formal defect. The children therefore inherit according to the rules of intestate succession, each taking one half. The partner, although intended to receive the assets, ends up with no rights.

The Court's Reasoning — Deconstructed

To annul the will, the court relies on Article 970 of the Civil Code. This provision states that a holographic will "is not valid if it is not written entirely, dated, and signed by the hand of the testator". Case law is consistent: the signature must be placed at the end of the deed, after the dispositions, to guarantee the authenticity and integrity of the document. By placing his signature at the top of the page, Mr G. did not comply with this requirement. The court considers this formal defect to be substantial: it prevents ensuring that the text was not altered after signature.

The judges dismiss Mrs D.'s argument that the deceased's wishes were clear. They reiterate that the formalities for a holographic will are matters of public policy: they cannot be derogated from, even if the content is undisputed. In other words, there is no such thing as a "valid in spirit" will if the form is not respected. This is a classic position, confirmed by the Court of Cassation on numerous occasions. The court therefore does not innovate: it applies a well-established rule.

In this case, the partner could not demonstrate that the signature placed at the top of the page was merely an insignificant "paraph". On the contrary, the unusual placement gave rise to a legitimate doubt as to the authenticity of the text. The court therefore pronounced the nullity of the will, resulting in the legal devolution of the estate.

What This Means for You — Practically

This decision reminds us of an essential rule: a will is not a trivial document. Its validity depends on strict compliance with formalities. For testators, the advice is clear: have your will checked by a notary or, failing that, scrupulously follow the rules of Article 970. Otherwise, your last wishes risk being nullified.

For heirs, if you discover a will that seems suspicious — misplaced signature, missing date, non-handwritten text — you can challenge it. You must act quickly: the action for nullity is time-barred five years from the opening of the will. In the Thann case, the children were vigilant and won. But if you hesitate, remember that court costs may be borne by you if you lose. A concrete example: imagine a will typed on a computer and merely signed by hand. It will be void, because the handwritten text is missing. Yet, uninformed heirs might agree to execute it. After this decision, they know they can challenge it.

In practice, if you are a legatee (beneficiary of a legacy), do not neglect form issues. Have the will certified by a notary if possible. Otherwise, ensure that forced heirs (children) cannot invoke a formal defect to oust you.

Four Tips to Avoid This Type of Dispute

• Draft your holographic will carefully: Write it entirely by hand, date it, and sign it strictly at the end of the text. No erasures, no signature at the top of the page.
• Use a notary for a notarial will: A notarial will (authentic deed) avoids any risk of formal defect. It is dictated to the notary and signed in his presence. This is the safest solution.
• Keep your will in a safe place: A holographic will can be lost or destroyed. Deposit it with a notary or at the central register of last wishes (FCDDV).
• Inform your heirs of the existence of the will: To avoid disputes, tell your loved ones where the will is and its general content. Transparency reduces conflicts.

Further Reading: Related Case Law and Developments

This decision is in line with consistent case law. The Court of Cassation, for instance, held in a judgment of 10 September 2014 (No. 13-23.879) that a holographic will with a signature in the margin was valid because the signature was placed after the text. Conversely, a will whose signature precedes the text was annulled by the Bordeaux Court of Appeal in 2018. The trend is therefore clear: judges are strict about the signature's location, considered an indicator of the deed's integrity.

Moreover, the law of 23 June 2006 relaxed certain rules for the international will, but the holographic will remains subject to the same rigour. In the future, legislative relaxation might be envisaged, but for now, form prevails over substance.

Checklist Before Taking Action

FAQ: Questions You May Have

• Can I contest a will if I disagree with its content? Yes, but you must invoke a formal defect or a ground of unworthiness (violence, fraud, etc.). Mere disagreement is not enough.
• What is the time limit to contest a will? Five years from the opening of the will (death of the testator). After that period, nullity can no longer be invoked.
• Do I need a lawyer? Yes, because the procedure is technical and the financial stakes are high. A lawyer specialising in succession law will assist you.
• What should I do if I discover a suspicious will? Consult a lawyer without delay. Do not disclose it before getting advice, as this could complicate matters.
• What are the costs? Lawyer's fees vary (fixed fee or hourly rate). If you win, they may be borne by the opposing party.
