In all cases where debts are contracted for necessaries by either spouse for the support and maintenance of the family, it shall be lawful for the creditor in this case to institute suit against the husband and wife for the price of such necessaries and, after obtaining a judgment, have an execution against the spouse contracting the debt alone; and, if no property of that spouse is found, execution may be levied upon and satisfied out of the separate property of the other spouse.
