Will I have to pay my husband's child support now that we are married?

In Louisiana, child support of either spouse becomes a "community" obligation. A prenuptial agreement in which the parties maintain separate property keeps the obligation from becoming one of the community, since there would be no "community" of property. However, the court will always consider the effect that a new spouse's income will have on the expenses of the payor-for example if the new spouse helps with any living expenses, such as food, clothing, rent, etc., that could be counted as additional income for the payor spouse.
