Art. 520a 2. In holographic wills ⁽¹⁾

If the formal defect in a holographic will consists in the day, month or year not being indicated correctly or at all, the will may be declared invalid only if the precise date cannot be ascertained in some other manner and is necessary in order to determine the testator’s testamentary capacity, the chronological order of multiple wills or any other issue affecting the validity of the will.
