If the father and mother have jointly endowed the common child without expressing the portion to which they intended to contribute, they are deemed to have each endowed half, either if the dowry was provided or promised in community property, or if it was provided in the personal property of one of the two spouses.
In the second case, the spouse whose personal property has been constituted as a dowry has, on the property of the other, an action for compensation for half of the said dowry, having regard to the value of the property given at the time of the endowment.
