Article 799

To be of sound mind, it is not necessary that the testator be in full possession of all his reasoning faculties, or that his mind be wholly unbroken, unimpaired, or unshattered by disease, injury or other cause.

It shall be sufficient if the testator was able at the time of making the will to know the nature of the estate to be disposed of, the proper objects of his bounty, and the character of the testamentary act. (n)
