The right of the plaintiff to recover in this suit depends on the question whether he was legally bound by *526the terms of his bond to Fessenden to pay the costs and expenses incurred by the latter in defending the two actions in which the title to the estate conveyed by the intestate to Fessenden had been tried without successfully impeaching its validity. A voluntary payment by the plaintiff, although made under a mistake or misapprehension as to his legal liability, would constitute no debt against the estate of the intestate. Such debt can arise only from a payment of money in accordance with the written contract into which the plaintiff entered at the request of and as surety for the deceased.
What then is the true interpretation of the conditions of the bond ? This is to be determined, not solely by looking at the words by which the agreement is manifested. These would often greatly mislead in the construction of contracts. The rule, that the written language is to govern to the exclusion of all extrinsic and paroi evidence, is always to be taken with the qualification that, in construing deeds or other instruments, the subject matter to which they relate and the circumstances under which they were made are to be taken into consideration, in order to arrive at the true import and meaning of the terms in which the parties have expressed their intention. Construing the words of the bond in the present case in a sense corresponding with the nature of the agreement and in the light of the transaction which took place contemporaneously with its execution and delivery, we are of opinion that it was intended only as an' additional or collateral security to the grantee for the performance by the grantor of the covenants contained in the deed. The parties did not contemplate that any unusual or extraordinary stipulations should accompany the conveyance. None were entered into as part of the contract of purchase and sale. The object of the grantee was to make it certain that in case of a breach of the covenants of seisin and warranty in his deed, he should be able to look to some person on whose solvency and ability to respond in damages for a breach of these covenants he could place more reliance than upon his grantor. Such is the natural and reasonable inference to be deduced from the fact that the bond was executed and delivered at the same time *527with the deed and as part of the same transaction. And it is confirmed by the evidence introduced by the plaintiff himself, from which it appears that the grantee declined to purchase the land unless he could have other security for the title than that of the grantor. On recurring to the words of the condition of the bond, it will be found that there is nothing inconsistent with this view of the object of the agreement, as derived from its subject matter and the circumstances under which it was entered, into by the parties. By a fair construction, it is clear that its stipulations were coextensive only with the covenants in the deed. The agreement is not absolute and unconditional that the obligor shall indemnify and keep harmless the grantee from all expenses in defending his title to the premises. If such had been the agreement, the plaintiff’s case would have rested upon a very strong foundation. But the stipulation is only that the grantor shall fulfil his covenants and pay and discharge all claims which any person or persons shall have on the premises, so that the grantee shall be indemnified and saved harmless from all expenses in defending the title. This clearly means that the indemnity for costs is to be the result or a consequence of a breach of the covenants in the deed, and the establishment of a well founded and lawful claim on the estate by a third person. The clear intent of the parties was, that the grantee was to be kept harmless only from the failure of the grantor to fulfil his covenants in the deed, and to pay all lawful claims which any persons might have on the estate. It would be giving a very broad construction to the language of the instrument to hold that it imposed on the obligor a liability to pay the expenses and costs of any and every suit, however groundless, which might be brought against the grantee at any time subsequently to the deed, in which the title to the premises might be drawn in question. The grantor by his covenants in the deed assumed no such obligation. He stipulated only to defend against the lawful claims of all persons. It would seem to follow that the obligor in the bond, who stood in the position of a surety for the grantor, took on himself the same, but no greater or more enlarged liability. To lead to the conclusion *528that the grantees intended to enter into a stipulation -so unusual as that for which the plaintiff contends, the language ought to be clear and unambiguous, so as to leave no room for any other interpretation. The result is, therefore, that there having been no breach of the covenants in the deed, no breach of the bond is shown.
