According to Article 938 of the Civil Code, only thetestator’s witnesses, if they are in poverty and cannot receive the means of maintenance due to them from persons who have a statutory maintenance obligation towards them, may demand from the heir who is not burdened with such an obligation the means of maintenance in relation to their needs and the value of his share of the inheritance. The heir may also satisfy this claim by paying the testator’s grandparents a sum of money corresponding to the value of one fourth of his share of the estate.
Therefore, since great-grandparents are not mentioned in the provision in question, they are not entitled to alimony.
