This is an action to quiet title to the undivided half of a certain piece of land described in the complaint. The plaintiffs are the children and heirs-at-law of John A. Campbell, deceased, who died May 21, 1873, seised in severalty of the whole of said tract of land, and it is conceded that the plaintiffs, as heirs of said decedent, are the owners of the undivided half of the land sued for, unless their title thereto has passed, either by virtue of a probate sale made in the administration of the estate of the decedent in 1874, or has been lost to them by the operation of the statute of limitations. Judgment in the lower court went for plaintiffs, and defendants appeal from the judgment and from an order denying their motion for a new trial.

Appellants claim title, first, as purchasers under the foreclosure of a mortgage made to M. J. Drais, now deceased, by one Church, and contend that Church had title through mesne conveyances by virtue of a probate sale of the property in 1874. We are satisfied, however, that the probate sale was' invalid and void. The petition under which the sale was made was filed on the seventeenth day of January, 1874, and is as follows: “The petition of C. A. Campbell, administrator of the estate of said deceased, respectfully shows that heretofore, to wit, on the fourteenth day of October, 1873, petitioner filed his petition praying for an order of sale of certain real estate, and showing the necessity therefor; that owing to a mistake in the inventory on file, the real property set forth in said petition did not belong to said estate; that therefore the order heretofore granted has become ineffectual; that a new inventory has been filed correctly describing the real estate belonging to said estate; that the facts which constitute the necessity for selling the real estate belonging to said estate still exists and are as set forth in said former petition, to which reference is hereby made, and petitioner prays may be taken as a part hereof; that a hotel constitutes a portion of the improvements on the real estate *257belonging to said estate, which said hotel contains furniture for the use thereof; that said furniture is worth about two hundred and thirteen dollars and sixty cents. Wherefore petitioner prays that an order of sale be granted authorizing said administrator to sell said real estate and furniture at public sale, and for such further order as may be proper.” (Signed by the attorney for the administrator and verified by the latter.) (It appears that a former petition for the sale of the property had been filed October 14, 1873, but that on account of the supposed insufficient description of the property it had been abandoned.) On the same day on which the second petition, above quoted, was filed, to wit, January 17, 1874, the order for the sale was made, and under this order the sale took place; and it is evident that the order for the sale made under these circumstances was invalid and void. Section 1538 of the Code of Civil Procedure provides that to obtain an order for the sale of real property a petition in writing must be made to the superior court setting forth certain facts; and section 1537 provides that, if it appears to the court from the petition that it is necessary to sell the real estate, an order must be made directing all persons interested in the estate to appear before the court at a time and place specified, not less than four nor more than ten weeks from the time of making such order, to show cause why an order should not be granted to the executor or administrator to sell so much of the real estate of the decedent as is necessary; and section 1539 provides that a copy of the order to show cause must be personally served on all persons- interested in the estate, including the heirs, at least ten days before the time of hearing, or be published four successive weeks in such newspaper as the court shall direct. In the ease at bar no such notice to show cause was made, and no service of any kind was made upon the respondents herein, who at that time were all minors, the oldest of them being only about twelve years old. The respondents contend that the petition did not give jurisdiction because it contained no description of the property to be sold; but if it could be held that a reference to various documents referred to in the petition might, under a very liberal construction, show a sufficient description of the property, still the absence of any order to show cause and *258of any service of the notice upon respondents are fatal to the validity of the sale. And this difficulty is not obviated by the fact that one Hall, who had been appointed attorney for minor heirs, did, on the date when said petition was made, file with the court a document of which the following is a copy: “Waiver of notice. The undersigned attorney, appointed to represent the minor heirs during the settlement of said estate, hereby waives notice of hearing of petition for sale of said real estate, and assents to an order of sale as prayed for in said petition, and for the reasons and causes therein stated.” The attorney for minor heirs can represent them only in a proceeding, which has been duly inaugurated and in which the court has already jurisdiction of the minors by such service of summons or notice as the code provides; he cannot waive their rights, or by any of^his acts invest the court with jurisdiction of their persons which it had not already acquired. Section 1718, which provides that “at or before the hearing of petitions .... for sales of real estate” the court may appoint some attorney to represent minors, evidently refers to some particular proceeding, and, taken in connection with other provisions of the code, clearly contemplates a proceeding in which the court has already acquired jurisdiction of the minors. Such was the ruling of the court touching the appointment of a guardian ad litem in Gray v. Palmer, 9 Cal. 628, where it was said: “The court had no right to appoint a guardian ad litem until the infant was properly before the court”; and in Galpin v. Page, 18 Wall. 365, the court say that the record showed “that the district court never acquired jurisdiction over the person of Franklina C. Gray in one of the actions, and therefore had no more authority to appoint a guardian ad litem for her in that action than it had to appoint attorneys for the other defendants.” These principles apply here; for while probate proceedings are at least quasi pro~ eeedings in rem, yet where the statute provides for the service of notice upon persons the same rule applies as in ordinary civil actions. The probate court, therefore, had no jurisdiction to make the order of sale under which appellants claim, and the sale was invalid and void. The fact that in 1874 section 1718 provided that “the appearance of the attorney is sufficient proof of the service of the notice on the parties he is appointed to *259represent” does not change the principle; this language implies that there must he notice to the parties and proof of the service of such notice, and merely means that after such service the “appearance” of the attorney, under certain circumstances, may he taken as sufficient proof of the fact of service. But in the case at bar it appears affirmatively that there was neither notice nor service, and that the attorney undertook to “waive” both.

The court below correctly held that the action was not barred by sections 318, 319, 320, and 1573 of the Code of Civil Procedure, or either of them. The sale under the probate order was made to one Hewitt, to whom in March, 1874, an administrator’s deed was given, which purported to convey to Hewitt in severalty the whole of the tract of land of which the undivided half is involved in this action. Hewitt held and occupied the land for a few days, and on March 11, 1874, conveyed the same by deed in severalty to one Cross, who held and occupied the same until February, 1876, when he conveyed the land by deed purporting to convey the whole in severalty to one Church, who at that time entered into the possession of the land, and has been in possession ever since. While Cross was in possession he allowed the widow of John A. Campbell, deceased, to build a house upon a portion of the land and to occupy it with her minor children, and in 1876 Church married the widow, and the children continued to live on the land with Church and their mother during and after their minority. They were raised and treated by Church substantially as if they had been his own children. Perhaps the evidence does not quite warrant the finding of the court that during all this time Church recognized the children as owning an undivided one-half, and held possession as a tenant in common with them. It is probable that for a period exceeding the statutory limitation of five years Church thought that he owned the land in severalty and treated it as if he so owned it. During most of that time, however, the plaintiffs were minors. Sometime between 1886 and 1890 Church told at least one of the plaintiffs that they, the children, had an interest in the property, and in 1S90, and before the execution of the mortgage to Drais, under which appellants claim, he said to all the plaintiffs that they owned one-half. *260Moreover, before Drais took the mortgage in December, 1890, Church informed him that -the children owned one-half,- and called his attention to an abstract of title showing that fact, and, after considerable conversation between them upon the subject, Drais. agreed to take the mortgage with the knowledge that although it covered the whole title to the land, yet it probably would be good for only an undivided one-half. All the plaintiffs had attained their majority -a little more than three years before the commencement of this action, and the final account of the administrator of the estate of Campbell, deceased, had been settled more than three years before the commencement of the action; and therefore appellants contend that the action is barred by section 1573 of the Code of Civil Procedure, which provides that no action shall be maintained for the recovery of an estate sold by an -executor or administrator unless it be commenced within three years next after the settlement of the final account; but plaintiffs had no cause of action against Church, for he acknowledged their title and was holding for -them as a tenant in common, and they could not have litigated their title in the foreclosure suit because they held by a paramount title and not under the mortgagor. They were not, therefore, called upon to bring any action until the purchasers under the foreclosure judgment sought to gain possession under their title founded upon that judgment.

The money which Hewitt paid for the land at -the original administrator’s sale was used partly to pay off debts of the estate, and there was a residue which was distributed, and a part of the money so distributed was received by the plaintiffs; and it is contended by appellants that this fact estops the plaintiffs from bringing this suit, and that, at all events, they cannot maintain the suit while retaining that money. Whether minor heirs who are merely passive during the administration of an estate, and enter, themselves, into no contracts, are bound to restore money which comes to them upon a void sale, is a question not necessary to be here determined (see Hill v. Den, 54 Cal. 6), for this principle would not apply here; there is no reason why the money, under any view of the law, should be paid to these present appellants, and there are no elements of estoppel here because Drais took his mortgage having knowledge *261of the true state of the title, or the means of acquiring it. If the affirmance of the judgment works any injustice to the appellants, we see no way under the law to prevent it.

The judgment and order appealed from are affirmed.
