Why this matters in practice
For lawyers: a testator who was of sound mind when signing is bound by the will even if they later become mentally incapacitated; a later incapacity does not invalidate the will. Conversely, if the intended legatee dies before the testator, the legacy lapses (§1698), the legatee must have capacity to receive at the moment of the testator's death. For clients: having a doctor's assessment at the time of signing can help establish the testator's sound mind if the will is later challenged.

Part of the original Civil and Commercial Code codification; no major subsequent amendment.

Arrêt de la Cour suprême n° 1790/2530 (1987)
A will in the official document form, being made by the authorities, needs no certificate from a doctor even where it is made in a hospital, because the district officer or deputy district officer who makes the will has knowledge and ability enough to judge whether the testator is of sound mind. That rests on the way an official document will is made and not on section 1654, whose own rule is that the testator's capacity is considered only as at the time the will is made. The same decision holds that a petition to appoint an estate administrator is lawful although it does not state what obstacle has arisen in administering the estate, where it states that the petitioner is an interested person and attaches the legatee's birth certificate showing that the legatee is a minor: the petitioner may petition under section 1713(1) and Civil Procedure Code section 55.
A will in the official document form was made in a hospital, and it was objected that there was no medical certificate as to the testator's mental state. The Supreme Court held that such a will, being made by the authorities, requires no certificate from a doctor, because the district officer or deputy district officer making it is competent to judge whether the testator is of sound mind. The Court also held the petition to appoint an estate administrator to be lawful even though it did not state the obstacle to administering the estate, because it stated that the petitioner was an interested person and attached the legatee's birth certificate showing the legatee to be a minor, so the petitioner had standing under section 1713(1) with Civil Procedure Code section 55. The decision did not turn on the timing rule in section 1654.
