delivered tiie opinion of the court.
The appellee, J. W. Bruffj sold to the appellant, J. H. Francis, a grist-mill engine and boiler, and accepted as payment from the latter two notes on David A. Dunn for one ^hundred dollars each, indorsed or assigned by the appellant for value received.
These notes were a lien on a small tract of land sold Dunn’s wife, and this land was subjected to the payment •of the debts by a judgment in equity, but failed to satisfy the full amount of the two notes and interest. The balance *192left unpaid, amounting to nearly as much as the principal of the notes assigned, the appellee recovered of the appellant, as assignors, by a judgment of the Trigg circuit court, and of that judgment they now complain. The appellee, in this petition, alleges “that the obligor, David A. Dunn, was, at the time of the assignment of the notes, insolvent, and owned no property,- and has so continued to be insolvent, and is now insolvent; that he had prosecuted the claims with due diligence, and therefore the appellants are liable.
There is no demurrer to the petition, but an answer filed, in which the appellant alleges that the appellee failed to prosecute his suit in equity with that diligence required, and further alleges facts showing that there was no action instituted at law, or judgment obtained at the first term of the court at which an action could have been properly broúght, and that when judgment was obtained no execution ever issued. He therefore denied the exercise of such diligence on the part of the assignee as would make him responsible, but failed to deny the allegation of insolvency, as alleged by the appellee, and for that reason the court below seems to have .rendered the judgment holding him responsible as assignor.
The petition was clearly defective, and has not been cured by the answer; but, on the contrary, that pleading discloses a state of fact that must necessarily bar the appellee’s right of recovery.
The fact of insolvency existing, not only at the time of the assignment, but continuously since that time, does not constitute a cause of action, or authorize the recovery against the. appellant; and although such allegations are made and not responded to, the liability of the assignor to the assignee is made to depend upon the existence .of *193other facts that must be alleged and proven in connection with the insolvency of the debtor before the assignor can be held responsible. The question of due diligence arises-as well as the question of insolvency, and the burden is on the assignee to establish both before he is entitled to recover. The one is a question of law, the other is a question of fact. What is due diligence must be determined by the court, and unless it appears from the appellee’s petition that legal diligence has been exercised by the assignee to recover from the debtor, a demurrer, if interposed to the petition, should be sustained; and if no demurrer, a judgment by default will be denied. The assignment is silent as to the obligation it imposes on either the assignor or the assignee; but the law implies an agreement on the part of the assignor to become liable to the assignee, if, after due diligence by suit against the obligor on the instrument assigned, he fails to make the debt by reason of the obligor’s insolvency. The assignee accepts the note with the assignment on that condition, and must exercise proper diligence by action to recover the money before the law .will imply an agreement on the part of the assignor to refund what he has received.
Exceptions may be found to this general rule, as where the obligor in the note has been released by a discharge in bankruptcy. That fact being admitted, no judgment could be obtained,' and if legal proceedings were instituted, it would result in a dismissal of the action, as the obligor has been released -from all liability. So if the obligor leaves the state, going beyond the jurisdiction of its legal tribunals, the assignee is not compelled to pursue him, but the mere fact of insolvency at the date of the assignment, or continuously thereafter, has never been held by the courts. *194of this state, in the many decisions had upon the subject, as affording any excuse for not prosecuting with due diligence a suit at law against the payor. The leading case on this .■subject is that of Smallwood v. Woods, reported in 1st Bibb, ■the opinion delivered in the year 1809, and it has been followed since that time in repeated adjudications.
In speaking of the liability of the assignor, and when he ■became responsible on his assignment, this court in that case said: ‘ ‘It is agreed that this responsibility is to accrue after ■due diligence by suit.” In that case, a Virginia case of Mackie’s ex’r v. Davis, and a former opinion of this court in the case of Boals v. McConnel, were adverted to as not settling the question as to what constituted due diligence, but leaving it at large, and without designating the ultimate point to which the assignee shall go in prosecuting the debtor before he has his recourse on the assignor. The declaration in that case only averred that the assignee had used due diligence, and the court below, having permitted the jury to take the record on that subject, the jury referred the matter back to the court to know whether the record amounted to due diligence. The facts being agreed, it was then a question of law with the court whether due diligence was used, and this court said: “It seems to follow that the assignee ought to take every compulsory process of the law against the debtor until his insolvency is established, or the suit and its incidental remedies prove insufficient to coerce payment.”
The doctrine of that case has been followed so long by the decisions of this court that it may now be regarded as among the fundamentals of the law, and the rule is now well settled, in the absence of some agreement, that before the assignee can recover of the assignor in a case *195like this, he must institute his action, at the first term of the court, obtain his judgment, have execution issued, and a return of no property found, without any unreasonable -delay. And as said in the case of Trimble v. Webb, 1st Monroe: ‘ ‘ Evidence of insolvency other than that proved ■by the force of execution itself has never been held sufficient to charge the assignor.” A failure to bring the action at the •first term of the court, when there is reasonable time after the assignment in which to institute it, or a failure to have •the execution issued, within a reasonable time, are such delays as will release the assignor from responsibility.
But it is maintained that the record of the action against, the debtor, with a judgment and return of no property, is only the evidence of the debtor’s insolvency, and that fact (the insolvency) being admitted by the answer, or not denied, requires no proof; that the record is only required to be produced when the issue as to insolvency is made, and then 'because it is the best evidence. This reasoning would be •sound if, as counsel contends, the insolvency of the debtor alone will authorize the recovery. The fallacy of the argument consists in the failure of counsel to recognize the fact that the record of the action against the debtor, showing a return of no property, is not the evidence of a right already existing in the assignee, but is the creation of the right itself, and is indispensable to a recovery, the fact of insolvency, without any legal proceeding against the debtor, creating no implied obligation on the part of the assignor •to the assignee. It is more like an action based on a record, as the failure to allege its existence leaves the assignee without a cause of action, or is analogous to cases where, in order to sustain the agreement or promise declared •on, one character of evidence will alone support the action. *196In such cases the evidence of the liability constitutes a part, of the cause of action: that is, it must be averred in the-petition that such evidence exists, for the reason that it is the basis of the recovery. In an action on a promise to pay the debt of another, while the'writing evidences the promise, the petition must allege the existence of the writing; or in an action to enforce a contract for the.sale of land, the petition must allege that the contract is in writing, notwithstanding the writing is the evidence of the contract between the parties. So, in an action by the assignee to recover of the assignor, due diligence, by prosecuting the obligor to insolvency, with a return of no property found, must be alleged and proven, and when not alleged, the issue may be made by a demurrer as well as by plea. If, when an issue of fact is raised as to the insolvency of the obligor, it becomes necessary to introduce an execution with a return of no properly found to support the action — and this is the only kind of evidence that can be adduced — it is necessary to allege in the petition facts showing that the debtor has-been prosecuted to insolvency.
Due diligence, says this court, in the case of Johnson v. Lewis, ist Dana, is a question of law. If so, the facts in this case are, that the maker of the notes was insolvent when they were assigned, and has so continued since that time. On these facts will the law enable the assignee to recover? Certainly not, because the assignee has shown no diligence in coercing payment. It further appears that a court intervened in the county of the debtor’s residence between the date of the assignment and the institution of the action on the notes; that the assignee had ample time to bring his suit at the first court, but neglected it, and has never had an execution issued on one of the judgments. These addi*197tional facts being agreed, will the law imply an agreement on the part of the assignor to the assignee to pay? The •answer must be in the negative, for the reasons already given — the want of proper diligence in coercing payment. Besides, if the question of diligence in this class of cases is • one of law, a petition that merely alleges the insolvency of the party at and since the assignment, and the prosecution ■of the maker with due diligence, must necessarily be held bad, as there are no facts alleged enabling the court to determine whether the proper diligence has or not been exercised. It is a mere legal conclusion, without any fact to support it, unless the question of insolvency, as is insisted by counsel for the appellee, is the only issue in such a case. The argument in support of the judgment below suggests this inquiry: When has the assignee a right of action against the assignor? If the views of counsel prevail, when it appears the obligor was insolvent at the date of the assignment, and continued insolvent to the bringing of the action by the assignee, a cause of action by the latter against the assignee exists.
The assignee is not required to coerce payment by an action at law, or to exercise any diligence if the insolvency •of the obligor in the note is admitted on demurrer, or by ■failure to answer, and a breach of the implied undertaking • occurs on the part of the assignor from the moment of the • assignment, and continues so long as the maker remains insolvent; and the only mode the assignor has of defeating the recovery is to deny the insolvency, and when this is ■done, the assignee has alleged a cause of action; but as there is an absence of record, with a return of no property, he is without evidence to support it. This cannot be the rule. The legal effect of an assignment of notes not regarded as commercial paper was at one time involved in *198much doubt, and learned jurists doubted the propriety o£ establishing a doctrine that imposed on the assignor an obligation to refund the consideration for such paper in the event the obligor in the paper proved to be insolvent; but in establishing the rule creating this liability, a correspondr ing duty was made to rest on the assignee, and that was to-coerce by suit the payment of the debt assigned, and to' use proper diligence in its prosecution. When this is done by the assignee, a cause of action arises, and such a record is not only evidence of the liability of the assignor, but is the foundation of the assignee’s right of recovery.
The rule here with ■ reference to- the right of recovery by the assignee is unlike that adopted in some of the other States. In Virginia, while a suit is in general necessary, the insolvency of the obligor is one substantial ground of' excuse for not instituting the action. (See Drane v. Schofield, 6 Leigh.) “If the obligor be insolvent at the time of the assignment, so that a suit against him would be wholly unavailing, it-is unnecessary for him to bring suit.” (Brown v. Ross, 6 Munford, and Carrier v. Hansbarger, 4 Leigh.) Such an excuse will not avail the assignee under the well settled doctrine of this court. In fact, a debtor may be insolvent, that is, unable to pay all his debts, and still with ample estate to pay the debt assigned, or he, may have no property subject to execution, and his credit good for double the amount of the debt assigned, and to preserve that credit would pay the debt to avoid litigation.
In the case of Jacob Clair v. T. & K. Barr, reported in 2 A. K. Marshall, page 658, it was alleged in the declaration that the maker of the note was, at its date, and when it became due, insolvent, and continued so until his death, without any estate to satisfy said-note or any fart of it. To this peti*199tiori the general issue was pleaded, and parol evidence of the insolvency excluded on .the trial. This court said “that notwithstanding the insolvency of the maker of the note, it was still necessary for the plaintiff to show that he had used due diligence to collect the debt, for although he was without property, he might not_ have been without credit, and if due diligence had been used to collect the money of him, he might have made an arrangement to secure or satisfy the-debt. To show due diligence, it was, we apprehend, incumbent on the plaintiff to prove that he had brought suit against the maker of the note before his death, as it was. practicable to have done so.”
It is true no question was raised as “to the sufficiency of the petition in that case, but it necessarily follows, that if the evidence of the same facts alleged in the petition would not excuse the assignee from suing, the statements in the petition containing the same facts, and nothing more, cannot be held to excuse, although the petition may be. taken for confessed. The insolvency of the debtor is no breach of the implied obligation on the part of the assignor to refund the money, unless the assignee has complied with his implied undertaking, by prosecuting the debtor without unreasonable delay, and obtaining a return of no property. The latter rule affords, ordinarily, a conclusive guide in determining when the cause of action accrues to the assignee, as well as the insolvency of the payee, and avoids the necessity of resorting to parol testimony as'to the pecuniary condition of the debtor, with the conflicting opinions of witnesses that would likely arise on such an issue after the lapse of years, or even at the date of the transaction itself. It is, therefore, an immaterial inquiry in this case whether the maker of these notes was solvent or insolvent, or whether the insolv*200■ency has been admitted or denied by the appellants, the right of recovery depending on the diligence exercised in ■coercing payment, and no diligence having been alleged or proven, the judgment should have been for the appellant.
