*238By the Court,
Beatty, J.:This is a suit upon an undertaking executed by the defendants as sureties in order to procure the discharge of an attachment which had been levied on the goods of John A. Steele, the defendant, in an action entitled as follows: “Miles Quillen and John Donahue, Administrator of the Estate of Edward Donahue, deceased, plaintiffs,- v. John A. Steele, defendant. ”
The complaint alleges the pendency of the former action, the levy of the attachment on the goods of Steele, the execution of the undertaking by defendants, the discharge of the attachment in consequence thereof, the recovery of judgment against Steele, the return of execution thereon unsatisfied, demand on the sureties, and their refusal to pay, etc.
The defendants admit the execution óf the undertaking; but deny the breach alleged. Their defense is that the parties and the cause of action in the former suit were changed without their consent, and that no judgment was, in fact, ever recovered upon the cause of action stated in the complaint upon which the attachment issued.
The plaintiff having recovered a judgment in the district court, the defendants moved for a new trial upon the ground, among others, that the decision of the court was not sustained by the evidence, in this: “That the evidence shows and proves that there is no judgment on record or otherwise in the action in which the bond sued upon was given.” The motion for a new trial was overruled, and the appeal is from that order as well as from the judgment. The question is thus presented for our consideration, whether there was such a change of the parties and of the cause of action in the suit against Steele as to discharge these defendants from liability as sureties on the undertaking given to release his goods from attachment. To determine this question it will be necessary to compare the original complaint, which was on file at the date of the execution of the undertaking, with the amended complaint upon which the judgment was rendered. The first was as follows: “Miles Quillen and *239John Donahue, administrator of the estate of Edward Donahue, deceased, the plaintiffs in the above entitled action, complaining of John A. Steele, the defendant in said action, allege: First. That the-said plaintiff, John Donahue, is administrator of the estate of Edward Donahue, deceased, late of said Lincoln county, duly appointed, qualified and acting as such administrator; that prior to the death of said Edward Donahue, the said Miles Quillen and Edward Donahue were partners in business at Pioche, in said county, and doing business under the firm name and style of Donahue & Quillen; that since the death of said Edward Donahue, the said plaintiff, Miles Quillen, and the said plaintiff, John Donahue, as such administrator, have and do now continue and carry on the business heretofore carried on by said firm of Donahue & Quillen under said firm name and style at Pioche aforesaid; that between the fifteenth day of August, A. D. 1871, and the third day of December, A.D. 1874, the said defendant became and was indebted to these plaintiffs in the sum of one thousand seven hundred and eighty-three dollars and forty cents, gold coin, and on an account for goods, wares and merchandise, consisting * * * and for money loaned and advanced by plaintiffs to defendant at his special instance and request,” etc.
This complaint was filed December 10, 1874, and the following day the defendants herein executed their undertaking, the material portion of which is as follows: “Now, therefore, we, the undersigned, residents, etc., in consideration of the release from attachment of all the property attached, and the discharge of said attachment, do hereby jointly and severally undertake in the said sum of two thousand six hundred and ten dollars and eighty cents, gold coin, and promise that in case the said plaintiffs recover judgment in the said action, the said defendant will, on demand, pay to the said plaintiffs, not exceeding the said sum of two thousand six hundred and ten dollars and eighty cents.”
Afterwards, on March 17, 1875, the following stipulation was entered into by the parties to the action, without the knowledge or consent of the sureties: “It is hereby stipu*240latecl that the plaintiffs in the above-entitled action have to and including Thursday, the twenty-seventh day of March, a.d. 1875, to file an amended complaint in the above-entitled action discontinuing as to John L. Donahue, administrator, etc., and amending in such other respects as the plaintiff may see fit.”
In pursuance of this stipulation, a new complaint was filed as follows: “Miles Quillen, surviving partner of the late firm of Quillen & Donahue, plaintiffs, v. John A. Steele, defendant.
“ And now comes the plaintiff above named, by leave of court first had and obtained, and files this amended complaint and discontinues as to the said John L. Donahue, administrator, etc., heretofore joined in this action, and alleges:
“ That, on the tenth day of February, A. D. 1873, and for more than two years prior thereto, the plaintiff and one Edward Donahue ivere partners, doing business as merchants and traders at Pioche, in said Lincoln county, under the firm name and style of Quillen & Donahue; that the said Edward Donahue, one of the partners of said firm, died at Pioche aforesaid on or about the eleventh day of February, A. D. 1873, leaving this plaintiff the sole survivor of the said firm of Quillen & Donahue; that, as such surviving partner of said firm, this plaintiff has had the care, custody and control of the business of the said late firm, and the assets thereof, and has, under the said firm name, carried on the business of said late firm, and is now so conducting the same and settling up, closing up the business of said late firm; that, between the first day of August, A. D. 1871, and the third day of December, a.d. 1874, the said defendant became and was indebted to this plaintiff, as such surviving partner of said firm, in the sum of eight hundred and five dollars and ninety cents, in gold coin, for and on account of goods, wares and merchandise, consisting, etc., by said late firm and by this plaintiff as such surviving partner thereof, between said last mentioned dates, sold and delivered to said defendant at his special instance and request, at” — etc.
*241There is a second count for money lent and paid, laid out and expended by the firm, and by the survivor, between the same dates, making the aggregate sum for which judgment is demanded the same as was claimed in the original complaint.
This amended or new complaint was answered by the defendant, and the case was tried and judgment rendered on the issues raised by the amended complaint and answer.
The appellants contend that the cause of action described and set forth in the original complaint was entirely distinct and different from the cause of action upon which the judgment was recovered. They claim that what is called an amended complaint was in reality a complaint in a new suit; that no such amendment would have been possible except for the stipulation of the parties, which they never consented to, and which does not bind them, though it may bind the parties to it. Theyinsist that their undertaking had reference only to the cause of action stated in the original complaint; that they bound themselves only “in case the said plaintiffs recover judgment in the said action,” and that they are not bound because one of said plaintiffs has recovered judgment in what is substantially another action.
The respondent, on the other hand, contends .that the cause of action stated in the amended complaint was the same as that stated in the original complaint; that the same proof would have supported either, and that the amendments might properly have been allowed, even without the stipulation above quoted.
"We have no doubt, looking to the original and amended complaints and the subsequent proceedings in the case, that the pleader who drew the original complaint intended to state the same cause, or rather causes of action, as those upon which judgment was recovered. But we have just as little doubt that he failed to do so'. The facts were undoubtedly that the firm of Quillen & Donahue had, during the lifetime of Edward Donahue, sold goods and advanced moneys to and for Steele, and that after the death of Edward Donahue the surviving partner had sold other goods and advanced other moneys to and for Steele. This is sub*242stantially what is averred in the amended complaint, with which we must pi’esume the proofs conformed. The right of action on both demands was in Quillen solely. As surviving partner he was entitled to sue in his own name and in his representative capacity for the amount due the firm, and was at liberty to unite with the firm debt a debt due to himself individually. (27 N. H. 289.) This is what he finally did in the amended complaint, though in a defective way; for he describes himself throughout as surviving partner, and claims to recover only in his representative capacity, whereas he should have stated separately the indebtedness accruing before the dissolution of the firm by the death of Edward Donahue and that accruing afterwards; and claimed the first in his representative and the second in his individual capacity. Defectively as it is drawn, however, it is easy to understand the meaning of the amended complaint and what proof would have been required to support it. But it seems impossible to construe the original complaint to mean the same thing or to be supportable by the same proofs. In fact, it requires a totally different construction, and could only have been supported by the proof of facts utterly variant from those stated in the amended complaint. To prove the case as it sood at the time the undertaking was executed and filed, it must have been shown that after the death of Edward Donahue, John Donahue and Quillen formed a partnership and sold goods and advanced money to Steele, and no proof of the sale of any goods or the advance of any money before the death of Edward Donahue would have been admissible, for nothing of the sort is alleged, and it was a legal impossibility that John Donahue could have any joint interest with Quillen in any demand which accrued during the lifetime of Edward Donahue. Under the new complaint, however, it was admissible to prove an indebtedness accruing to Quillen and Edward Donahue during the lifetime of the latter. Of this there can be no question; a demand could be proved uuder the new complaint which was in fact and in law entirely distinct from any that could have been proved under the original complaint. This is conceded; but it is contended that the in*243tention of the pleader who drew the original complaint to include the demand accruing to Quillen and Edward Donahue was manifest, and therefore that the amendment subsequently made worked no change in the liability of the sureties. In the light of subsequent disclosures it may appear that the pleader intended to state in the original complaint the same cause of action as that stated in the amended complaint. But the defendants in this action at the time they became sureties for the defendant in that action had not the benefit of the subsequent disclosures to aid them in arriving at the meaning the original complaint may have been intended to express. They read it in- its own light as a statement of the facts constituting the cause of action, and not as the statement of an erroneous theory of the legal effect of other facts which were not disclosed. They found it stated that Steele had become indebted to Quillen and John Donahue on account of goods sold and money advanced by them, “these plaintiffs,” and they were not bound to infer — they had no reason to infer — that the demand was really for goods sold, not by Quillen and John Donahue after the death of Edward, but for goods sold by Quillen and Edward Donahue during Edward’s lifetime. They may have known that John Donahue as administrator had no right and no business to enter into a partnership with the survivor of his intestate, but the fact that he had done so being verified they had a right to believe it. The law might not countenance such a proceeding, but it is well known that many things are actually done that are not strictly according to law. There wás no reason, therefore, why the original complaint'should not have been construed, according to its plain and obvious import, as the statement of a cause of action existing in favor of Quillen and John Donahue. If so, the liability of these defendants was extinguished by the amendment to the complaint; for there can be no doubt that the judgment against Steele was based, in part at least, upon an account for goods sold and money advanced by Quillen and Edward Donahue, a cause of action which was not only not included in the original complaint, but could not have been united with the cause of action therein stated.
*244The law does not permit the liability of a surety to be changed without his consent. The general doctrine on this subject is very clearly stated in the opinion of Storey, J., in the case of Miller v. Stewart, (9 Wheat., 702): “Nothing can be clearer, both upon principle and authority, than the doctrine that the liability of a surety is not to be extended by implication beyond the terms of his contract. To the extent, and in the manner, and under the circumstances pointed out in his obligation, he is bound, and no further. It is not sufficient that he may sustain no injury by a change in the contract, or that it may be even for his benefit. He has a right to stand upon the very terms of his contract, and if he does not assent to any variation of it, and a variation is made, it is fatal.” To the same effect are Myers v. Edge, (7 Term. Rep., 254), and Walsh et al v. Bailie, (10 Johns., 181). More directly in point is the case of Bean v. Parker, 17 Mass., 602. That was scire facias against the sureties on a bail bond. The defendants pleaded that after entry of the original action in court, there being another action pending in favor of the defendants against the plaintiff, the parties entered into a rule of court whereby they submitted the two actions, and all demands between the parties, to the determination of referees: and that the sum for which judgment was rendered was the sum reported by said referees as* the balance of all demands between the parties. To this plea the plaintiff replied that the sum awarded by the referees was part of the same sum demanded in the suit in which the defendants became bail, the referees having only deducted from plaintiff’s claim in that suit part of the cross-demand, which could not have been filed in set-off or given in evidence on the trial of the action.
If this replication was true, it showed conclusively that the sureties on the bail bond had been benefited by the reference of all demands between the parties. The judgment against their principal was for a part only of what would otherwise have been recovered. The defendants, by demurring to the replication, confessed that it was true, and the court thereupon decided: “When one becomes bail for another he is responsible only for the demand contained in *245the suit upon which the principal has been arrested. Another demand cannot be substituted or added without defeating the contract of bail. It is immaterial whether the substituted demand be greater or less than the one contained in the writ. The bail has a right to say in Jiaeo fcadera ven-i, and no other. * * * Nor is it any answer to say that the bail has gained by the agreement to refer, as is alleged in the replication to these pleas, for this will make liis contract of bail, which ought to be definite and certain, to depend upon transactions of the parties, in which the bail has no concern, subsequent to his entering into the contract, and put him to the inconvenience of proving facts which may be entirely beyond his reach. "When he enters into his contract he pledges himself, on certain contingencies, to pay what may be recovered in the usual course of law in the action to which his bond refers.” (See also Langley v. Adams, 40 Maine, 125; Hyer et al. v. Smith, 3 Cranch C. C. 437; Fairfield v. Baldwin, 12 Pick. 388; Andre v. Fitzhugh, 18 Mich. 93; Fullerton v. Campbell, 25 Penn. St. 345.)- The principle announced in these cases is well settled and is perfectly applicable here.
The cases cited by the respondent are not applicable. No one can deny that a court has the power to amend pleadings by adding or striking out the names of parties, plaintiff or defendant. The power is expressly conferred by section 08 of the practice act. Put, although this power may be and is very liberally exercised, and very properly so, as between the parties to the action in furtherance of justice, it cannot be exercised with the effect of changing the rights and liabilities of third parties. No case has been brought to our attention, and we think none can be found, in which sureties have been held liable after a change of the cause of action.
The case of Lord v. Clark (14 Pick. 223), is relied on as a case in point against our conclusion. In that case, the facts stated in the writ were that Wilson being indebted to Lord, Holbrook and one Bichardson, since deceased, partners, promised Lord and Holbrook, the survivors, etc. It was held, and properly held, that striking out the name of *246the deceased partner did not release Wilson’s bail. The difference between that case and this is that no amendment in that case was actually required in order to support the judgment. The facts were stated correctly, and it appeared on the face of the record that one of the persons named as a plaintiff was dead .and, therefore, that his name was merely surplusage.
If, in this case, the facts had been correctly stated — if, instead of averring that Quillen and John Donahue, as partners, had sold goods and advanced money to Steele, it had been shown that the goods were sold and the money advanced by Quillen and Edward Donahue, it would have appeared from the face of the complaint that John Donahue was not a proper party to the action, and his name might have been stricken out without changing the cause of action. The case in 14 Pickering would then have been an authority in respondent’s favor.
The other cases referred to are liable to the same criticism. Either they were not actions against sureties, or there had been no change in the cause of action with reference to which they contracted.
• The judgment and order appealed from are reversed, and cause remanded.
