Defendant appeals from an interlocutory decree in partition, which adjudges that the plaintiff and defendant are tenants in common of the real property involved, and that the plaintiff is the owner of an undivided fifty-five one-hundredths thereof and the defendant the owner of an undivided forty-five one-hundredths thereof. The grounds alleged by defendant in support of his appeal have been variously stated, but, when analyzed, they all resolve themselves into the single contention that the evidence is insufficient to support the finding of the trial court to the effect that the plaintiff is the owner of an undivided fifty-five one-hundredths interest in the property. Respondent, in her answering brief discusses all oi the contentions presented by appellant, and, in addition thereto, makes the point that appellant is not entitled to the consideration by this court of any of his contentions, for the reason that he is not a party aggrieved by the judgment appealed from. Section 758 of the Code of Civil Procedure provides, among other things, that a defendant in an action for partition of real property “must set forth his estate or interest in the property.” A consideration of the legislative history of this section, from its enactment as section 270 of the Practice Act to and including the amendment of 1907, together with the code commissioner’s note in connection therewith, leads to the conclusion that this code requirement was intended by the legislature to be mandatory. This conclusion is supported by the decision in Miller v. Sharp, 48 Cal. 394 , so holding, in effect, with respect to the corresponding provision in section 753 of the Code of Civil Procedure, which provided: “The interests of all persons in the property, whether such persons be known or unknown, must be set forth in the complaint ... as far as known to the plaintiff . . . ” The court there said: “The statute concerning partition (sec. 759) provides that the rights of the several parties, plaintiff as wrell as defendants, may be put in issue, tried and determined, but it does not provide that rights such as these may be tried or determined without being put in issue.” The plaintiff in her complaint herein alleged that she and the defendant were owners," as tenants in common, of the described land, and that she was the owner of an undivided four-sevenths interest therein and the defendant owner of an undivided three-sevenths interest therein. The defendant, in his amended answer, not only failed to set forth his estate or interest in the property, but affirmatively alleged, in effect, that he had no estate or interest therein. That this was not due to oversight or inadvertence appears from the circumstance that by his original answer he claimed ownership in himself of the whole interest in the land in question, a claim which he expressly repudiated by his amended answer. We are thus confronted with the situation of an appellant who, in the court below, expressly disclaimed any interest in the land, and now complains to this court because he was awarded only a forty-five one-hundredths interest therein. The decree appealed from relates to the property only, and awards no personal judgment or relief of any kind as against the de fendant personally. Under these circumstances we are unable to conceive of any process of reasoning by which the defendant can justly claim to have been aggrieved thereby.

We find no authority in this state expressly in point upon this situation, but in Flannigan v. Towle, 8 Cal. App. 229 [ 96 Pac. 507 ], a suit to quiet title, wherein several tax deeds were under attack by plaintiffs, and plaintiffs admitted at the trial that they could show no title to the land described in any of these deeds except one, it was held that they were not aggrieved parties so far as the judgment related to the other tracts. (See, also, Mono County Irr. Co. v. State, 32 Cal. App, 184 [ 167 Pac. 199 ] ; 2 Cal. Juris. 212, 217, secs. 54-57; Estate of Piper, 147 Cal. 606 [ 82 Pac. 246 ]; Blythe v. Ayres, 102 Cal. 254 [ 36 Pac. 522 ]; Myers v. Mahoney, 43 Neb. 208 [ 61 N. W. 580 ]; Palmer v. Merrill, 70 Iowa, 227 [ 30 N. W. 494 ]; Hinton v. Winsor, 2 Wyo. 206 ; 3 C. J. 628.)

Appellant has suggested no answer to the point thus raised by respondent, and, finding none ourselves, we are constrained to the conclusion that it is well taken.

The judgment is affirmed.
