The plaintiffs admit that they cannot maintain a joint action at law against the present defendants under Rev. Sts. c. 70, § 13 & seq. They therefore seek to amend by changing the present action into a bill in equity, which is the remedy prescribed by § 16 of the same chapter in cases like the present, where more than one person are liable for a debt as heirs, next of kin, devisees or legatees.
It is very clear that the right of the plaintiff to make this amendment is not affected by St. 1853, c. 371, giving equitable remedies in suits at law, because the present suit, having been commenced before that act took effect, is within the provision of § 5, by which pending actions are expressly excepted from its operation. Nor has the court power, under the Rev. Sts. c. 100, §§ 20-22, to allow such an amendment. The provisions in these sections were taken substantially from St. 1784, c. 28, § 14, and were not intended essentially to change the law, or to give greater powers to the court in granting amendments. Davenport v. Holland, 2 Cush. 12. It was always held under that statute that it was not competent for the court to allow amendments changing the form of action. Haynes v. Morgan, 3 Mass. 210. Ball v. Claflin, 5 Pick. 303. Guilford v. Adams, 19 Pick. 376. And that no such power was intended to be given by the former statutes is strongly implied in St. 1836, c. 273, § 3, by which authority was given to the court to permit a party to amend by changing the form of action, in order to adapt it to the nature of his claim. There can be no doubt, therefore, that before the enactment of the last named statute, the amendment asked for in the present case would have been entirely inadmissible; because, *439if a party could not amend so as to change the form of his action at law, a fortiori he could not turn it into a bill in equity.
The question is therefore narrowed to the true interpretation of St. 1836, c. 273, § 3. It is quite obvious that this statute was intended to apply only to actions at law; and although in some cases the term “ civil action ” is broad enough to include bills in equity and other proceedings in courts of justice, not coming williin the strict meaning of a suit at law, it is manifestly used in this statute in its more restricted and technical sense. The terms “ special pleading ” and “ general issue ” are properly applicable only to actions at law; and the connection in which they stand in the statute, together with the provision authorizing the courts to make rules to “ prevent surprise, and to afford opportunity for preparation for trial,” clearly show that the sole purpose of the act was to regulate proceedings in such actions. By the provision therefore in § 3, authorizing the allowance of amendments by changing the form of action, nothing more was intended than to confer an authority on the courts, which by previous decisions had been determined not to exist; so that one form of action at law might be changed to another, in order to adapt the declaration to the nature of the plaintiff’s legal claim as it might be disclosed after the commencement of the suit. It is obvious that amendments of this kind only remove technical objections to the declaration, so that the true cause of action may be tried on its merits ; but they do not at all affect the substantial rights of parties, or in any degree change or modify the remedy to which they may be entitled as the fruit of an action at law.
But it would be far otherwise if a plaintiff were allowed to change an action at law into a bill in equity, or a bill in equity into an action at law; for one would be equally admissible wilh the other. That would be to change by amendment not only the form, but the entire nature of the suit; to transfer it to a new, distinct and independent jurisdiction, and to subject the defendant to a wholly different system of administering rights and remedies from that to which he was liable under the original process. We think such was not the intention of the legislature. So great a change in the practice of courts would not have been *440eft to implication; and the language of the statute, as we have already said, is strictly applicable only to actions at law.
Besides, the power of allowing amendments is a general authority conferred by the statutes upon the court of common pleas as well as upon this court. No greater authority in this respect is given to one court than to the other. But it is clear that the construction contended for by the plaintiffs would give this court much greater power to allow amendments. The question of the competency of an amendment, such as is asked for in the present case, would then depend on the accidental circumstance that the action was pending in this court, which has a large equity jurisdiction. In the court of common pleas, which has concurrent jurisdiction with this court in most personal actions at law, but possesses no general equity jurisdiction, such an amendment could not be made, because its allowance would take away the jurisdiction of the court. For these reasons, we are of opinion that the amendment was rightly rejected by the presiding judge.
The claim of the plaintiffs against the heirs of the intestate, Ephraim Hapgood, accrued upon payment by them of the debt for which they were jointly liable with him. Until such payment was made, neither of them had any cause of action against the estate of the deceased. It was this payment which created their claim. They were not bound by any legal obligation to the deceased to pay it sooner. The present suit having béen commenced within a year from the time of such payment, but after the final settlement of the estate of the deceased, and after the expiration of the time limited for the commencement of actions against the administrator, was seasonably commenced in order to charge the heirs at law, under Rev. Sts. c. 70, §§ 13,14. Hall v. Bumstead, 20 Pick. 7. Wood v. Leland, 22 Pick. 503, and 1 Met. 387. Upon making proper amendments, therefore, by striking out parties improperly joined in this suit, one of the two plaintiffs, having paid a part of the debt out of his own separate funds, can recover an aliquot part of the amount =o paid by him, so fa as it was the proper debt of the intestate, »gainst <me if the defendants, as his hen- at law.
