The opinion of the court was delivered by
Burch, J.:The action was one for overdue and unpaid installments of alimony awarded the plaintiff by a decree of divorce. A second cause of action was j oined for expenditures *270for the support of a minor child of the parties. The plaintiff recovered, and the defendant appeals. . -
The defense to the alimony feature of the case was that the decree of divorce and alimony was procured by the plaintiff’s fraud upon the court, in which the defendant acquiesced because of certain false representations made to him by the plaintiff respecting the state of her health. A demurrer was properly sustained to this defense because the fraud consisted in sustaining fictitious grounds for divorce by false testimony, the very matters w*hich the court, with full jurisdiction of the parties and of the subject matter, had under consideration. (Bleakley v. Barclay, 75 Kan. 462, 470, 89 Pac. 906; Plaster Co. v. Blue Rapids Township, 81 Kan. 730, 106 Pac. 1079; McCormick v. McCormick, 82 Kan. 31, 107 Pac. 546; Miller v. Miller, 89 Kan. 151, 156, 130 Pac. 681.)
The original decree provided that it should not be a lien on the defendant’s property. The judgment .in the present action awarded execution. It is said this changed the terms of the original decree. Such is not the case. The award of alimony is not increased or given greater efficiency. When installments became due and were not paid they became collectible by suit, judgment and execution in the ordinary way.
The plaintiff was allowed fifty dollars per month for the period of seven months as a reasonable sum for the maintenance of the minor child while with her mother. There was no allegation or proof of actual expenditures to that amount.
The plaintiff can recover nothing but her outlay made necessary by the defendant’s neglect of parental duty. Expenditures of this character can not be recovered in a simple action of debt because the propriety of all such expenditures depends upon a variety of considerations. The action must in the nature of things be equitable in character. (Riggs v. Riggs, 91 Kan. 593, 138 Pac. 628.) But the fact that such expenditures must be reasonable and just under all the circumstances, to authorize recovery, does not permit recovery of what would be a reasonable sum if it had been advanced, but which was not advanced.
Doubtless because the second cause of action was tried on a wrong theory, some errors were committed in the introduction and exclusion of evidence and in restricting the right of cross-examination.
*271The judgment on the first cause of action is affirmed. The judgment on the second cause of action is reversed, and the cause is remanded for further proceedings.
