delivered the opinion of the court.

In 1918, Herschel Hanson was appointed administrator of the estate of George Van Parker, deceased, and duly qualified by taking the statutory oath and giving bond in the sum of $2,000, with John O. Seidel and Chris Christensen as sureties. In January, 1919, the court ordered the administrator to sell the real property belonging to the estate, but required an additional bond in the sum of $2,000, which was furnished, with the United States Fidelity & Guaranty Company as surety. From the sale Hanson realized $1,700, and soon thereafter left the state without accounting for the proceeds. In June, 1919, *28 lie was removed as administrator, and Edgar J. Baker was appointed in his stead. Thereafter Hanson ¡transmitted to the court his final account, which was duly approved on February 2, 1921. In the order approving the account the court determined that Hanson had received $1,700 and was entitled to credit for $1,049.14, leaving a balance of $650.86 due to his successor in office. In November, 1921, a citation was issued to Hanson and to the sureties upon each of his bonds, requiring them to appear in court on January 3, 1922, and show cause, if any they had, why Hanson should not be examined concerning ten cattle, eight horses and some farm machinery, alleged to belong to the estate and which he had failed to mention in his final report. Hanson, being beyond the jurisdiction of the court, could not be compelled to' appear in person, but he transmitted an answer in which he denied that he had received a portion of the property and stated the disposition he had made of that portion which he did receive.

The Fidelity Company disclaimed any responsibility for the acts of Hanson in dealing with the personal property, and referred to Hanson’s answer for a further return to the citation.

A hearing was had and on April 24, 1922, the court found that Hanson had received ten head of cattle, seven head of horses and some farm machinery, belonging to the estate, of the aggregate value of $1,290, which he had converted to his own use or otherwise wrongfully disposed of, and which he had failed to mention in his final account. The court also ordered that Hanson pay over to his successor in office the sum of $1,290, and also the further sum of $650.86 found due by the order of February 2, 1921, and, if payment were not made, that the present administrator proceed by suit or otherwise to collect the amounts. 'Thereafter this action was commenced by Baker, as administrator, against Hanson, Seidel, Christensen and the Fidelity Company, to recover $1,940.86, with interest. The complaint sets forth the probate proceedings in substance, and discloses that the amount demanded is made *29 np of the two items mentioned — $650.86, the balance from the sale of the real property, and $1,290, the value of the personal property alleged to have been wrongfully converted.

To this complaint Seidel and Christensen interposed a general demurrer, and the Fidelity 'Company a demurrer, general and special. Hanson was not served with summons and did not appear. Each of the demurrers was overruled and answers were filed, one by Seidel and Christensen jointly, and a separate answer by the Fidelity Company. Upon motion of plaintiff a portion of each answer was stricken, and a demurrer to each answer was sustained. The defendants, declining to plead further, suffered judgment to be rendered and entered against them and appealed.

The questions presented involve a consideration of the char- • acter of the claims sued upon, the character of the bonds, and the liability of the sureties.

1. The claim for $650.86 is liquidated. When the court approved the former administrator’s final account, and adjudged that there was due to the present administrator the sum of $650.86, and there was no appeal and no appropriate proceeding had to surcharge the account or to have the order modified, the adjudication fixed the liability of Hanson for that amount at least, and became conclusive upon the sureties. (Botkin v. Kleinschmidt, 21 Mont. 1, 69 Am. St. Rep. 641, 52 Pac. 563; Kenck v. Parchen, 22 Mont. 519, 74 Am. St. Rep. 625, 57 Pac. 94; In re Smith’s Estate, 60 Mont. 276, 199 Pac. 696; Irwin v. Backus, 25 Cal. 214, 85 Am. Dec. 125; Chaquette v. Ortet, 60 Cal. 594.)

2. The bond upon which Seidel and Christensen are sure- ties is the general bond of an administrator given pursuant to the requirements of section 10088, Revised Codes of 1921, as a condition precedent to letters being issued. It secures the faithful performance of all the duties imposed upon the administrator, including the duty to account for the moneys coming into his hands by virtue of his office, whether received from the sale of real property or otherwise. (Hughes *30 v. Goodale, 26 Mont. 93, 91 Am. St. Rep. 410, 66 Pac. 702; Evans v. Gerken, 105 Cal. 311, 38 Pac. 725; 24 C. J. 1064.)

The bond upon which the Fidelity Company is surety is the additional bond for which provision is made in section 10089, and which may be exacted upon a sale of real property belonging to the estate. It secures the faithful performance of the duty of the administrator with respect to the conduct of the sale and the proper disposition of the proceeds, but it is not security for the acts of the administrator with respect to any other property belonging to the estate. In 24 C. J. 624, the rule is stated as follows: “The special bond 'given for the sale is in the nature of additional security, and creates a liability, not for the general administration of the estate, but only with reference to the sale.” (Durfee v. Joslyn, 92 Mich. 211, 52 N. W. 626; Burtch v. State, 17 Ind. 506; Mann v. Everts, 64 Wis. 372, 25 N. W. 209.)

The duty of the administrator to account for the personal property or its value is secured by the general bond only; whereas his duty to account for the proceeds of the sale of real property is secured by 'both bonds.

It is contended, however, that the liability upon the addi , tional bond does not attach until the penalty of the general bond is exhausted, and authorities are cited which -support the contention; but in our'judgment the rule which they declare should not be adopted in this state. We think it apparent from a cursory reading of section 10089 that the exaction of an additional bond upon the sale of real property is a precautionary measure designed to secure the funds derived from the sale; that the sureties on that bond and the sureties on the administrator’s general bond are equally liable; and that the nature of their respective obligations is the same so far as the conduct of the sale and the disposition of the proceeds are concerned. (Durfee v. Joslyn, above.)

3. From what has been said it follows that there is a misjoinder of parties defendant so far as the cause of action for the recovery of the $1,290 is concerned.

*31 4. There is also a misjoinder of causes of action. Section 9130, Kevised Codes, enumerates the causes of action which may he united, and concludes: ‘ ‘ The causes of action so united must all appear on the face of the complaint to belong to one only of these classes, and must affect all the parties to the action.” As observed before, the cause of action upon the claim for $650.86 does affect all of these parties, but the cause of action upon the claim for $1,290 does not affect the defendant Fidelity Company; hence the two causes of action cannot be joined, and the court erred in overruling the special demurrer to the complaint.

In their argument in support of the contention that these causes of action and the several defendants are properly joined, counsel for plaintiff fail to distinguish between the additional bond which may be exacted upon the sale of real property, and the fuither security which may be required whenever the general bond of the administrator is deemed to be insufficient. Provision for such further security is made in sections 10094, 10099 and 10102, Revised Codes, and, whenever required, it becomes in contemplation of law a part of the general bond and the sureties become subject to the same measure of liability; but it is altogether distinct from the additional bond which may be required upon the sale of real property. The cases cited by counsel have no application to the facts here presented.

5. Plaintiff relies upon the order of April 24, 1922, as an adjudication that the sum of $1,290 is due from Hanson to the estate, and, since there was not any appeal from that order, nor any other appropriate proceedings had to reopen the matter, it is contended that the order became final and conclusive upon Hanson and likewise upon the sureties.

So far as the Fidelity Company is concerned, it would make no difference whether the order of April 24 is or is not an order approving a supplemental final account of the former administrator, since that company is. not responsible for the acts of the administrator in dealing with the personal property *32 belonging to tbe estate; and neither would the character of that order affect the question of misjoinder of causes of action or parties defendant. But the character of the order does affect the defendants Seidel and Christensen, for, if it were in point of law an order approving an account of the former administrator, these sureties are concluded by it.

The citation issued in November, 1921, was issued pursuant to the provisions of sections 7505-7506, Revised Codes of 1907 (secs. 10141-10142, Rev. Codes 1921), and the only thing which the court could do in the matter was to order Hanson to make disclosure. In considering these sections of the Code, this court in In re Roberts’ Estate, 48 Mont. 40, 135 Pac. 909, said: “These provisions are remedial in their nature, and confer power upon the court, when sitting in probate proceedings, analogous in its scope and object to the power of a court in chancery upon bills of discovery. (Mesmer v. Jenkins, 61 Cal. 151.) The proceeding authorized by them is of an ancillary character, however, and is confined to securing .a discovery of evidence upon which the administrator or executor may recover assets belonging to the estate which would otherwise be lost. The adjudication of disputed rights of property is not within their scope, for the order which section 7506 authorizes the court to make cannot go further than to require a disclosure which may be used in an action pending or to be brought in behalf of the estate. (Ex parte Casey, 71 Cal. 269, 12 Pac. 118.) The order cannot finally adjudicate any right. The utmost effect such an order could have in any ease would be to fix the rule of evidence to be observed in an action brought to establish the right asserted in behalf of the estate. ’ ’ To the same effect is the decision in State ex rel. Cohen v. District Court, 53 Mont. 210, 162 Pac. 1053.

Counsel for plaintiff insist that the citation -was not issued for the purpose of discovery but to compel the former administrator to account, under the provisions of section 10295, Revised Codes; but the answer to this is that the former administrator had already rendered a final account which had *33 been approved, and, in the absence of an appeal from the order, section 10303 provides the exclusive method by which the account could be reopened or the order modified, and that method was not observed in this instance. If the order of April 24 assumes to be an order approving a supplemental final account, it is sufficient to say that the court was without authority to make it. Whatever may be its form or designation, it is in legal effect only an order for disclosure.

6. Defendants Seidel and Christensen insist that the order of February 2, 1921, approving the final account of the former administrator, fixed their ultimate liability at $650.86, and they pleaded the order as res judicata.

Section 10303, Revised Codes, provides: “The settlement of any account and the allowance thereof by the court or judge, or upon appeal, is conclusive against all persons in any way interested in the estate [except persons laboring under disability] ; provided, the court may, upon motion of any party interested, or upon its own motion, within sixty days after the rendition of the decree in cases of inadvertence, or within sixty days after the discovery of the facts constituting the fraud, reopen or set aside any decree of any settlement on the grounds of inadvertence or fraud.”

Under a similar statute the courts of California have held repeatedly that the order approving an administrator’s final account is conclusive “of all matters involved which might have been disputed at the hearing, although no objection was in fact made.” (In re McDougald’s Estate, 146 Cal. 191, 79 Pac. 878; Estate of Adams, 131 Cal. 415, 63 Pac. 838; Estate of Ross, 179 Cal. 358, 182 Pac. 303.) This appears to be the general rule, and we approve it. (24 C. J. 1029.) But it cannot be urged seriously that, if an administrator is artful enough fraudulently to conceal property belonging to the estate and wrongfully fail to include it in his report, the order approving the report condones his misdeeds and relieves him and the sureties on his general bond from all liability for such *34 property. Tbe bare statement of tbe proposition is its own answer. (24 C. J. 1069.)

It does not appear from the record before us that at the time Hanson presented his final report the present administrator or anyone else interested in the estate knew of the existence of the personal property or that it belonged to the estate; hence the allegations in their answer are not sufficient to make the plea of former adjudication available.

But these defendants insist, further, that if they may not rely upon the order approving the final account as limiting their liability to $650.68, they are entitled to defend against the claim of $1,290, and to that end to show what amount of personal property came into the hands of the administrator and what disposition he made of it. This contention is unanswerable. The claim for $1,290 is altogether unliquidated. The order for disclosure made upon the hearing on the return to the citation is only prima facie evidence of the right of the present administrator to the personal property (sec. 10142, Rev. Codes), and the court erred in striking the special defense" from their answer.

The judgment is reversed and the cause is remanded for further proceeding's not inconsistent with the views herein expressed.

Reversed and remanded.
