In case the husband or wife abandons the other and leaves the state, and is absent therefrom for one year, without providing for the maintenance and support of his or her family, or is imprisoned in the penitentiary, the circuit court in the county where the husband or wife so abandoned or, not confined, resides, may, on application by petition, setting forth fully the facts, if the court is satisfied of the necessity by the evidence, authorize him or her to manage, control, sell or incumber the property of the other, as shall be necessary, in the judgment of the court, for the support and maintenance of the family, and for the purpose of paying debts of the other, or debts contracted for the support of the family. Notice of such proceedings shall be given as in other civil actions, and anything done under or by virtue of the order or judgment of the court, shall be valid to the same extent as if the same were done by the party owning the property.
