delivered the opinion of the court.
Appellant filed her bill in chancery in the Circuit Court of McLean county, in which she charges that she is the owner and holder of two promissory notes, each for the sum of $1,250, signed by J. W. Bishop, payable to the order of Henry S. Dooley in 3 years from their date and drawing 6 per cent annual interest, payable annually; that on the back of each of these notes is indorsed the words “I hereby guarantee this *159loan. Henry S. Dooley”; that appellant purchased these notes before maturity from the administrator of the estate of Mary A. Brown, now deceased, who was in her lifetime a distracted person; that these notes show on their face that they were secured by a mortgage on real estate; that when they were given, Henry S. Dooley was the conservator of the said Mary A. Brown, now deceased, but then a distracted person; that shortly after these notes were given he placed the indorsement and guaranty on them as it now appears and turned them over to himself as such conservator and thereupon made a report of such transaction to the County Court of McLean county, and asked for and received credit in his account as such conservator for the amount of money paid out by him for said notes; that at the time said notes were given, J. W. Bishop, who signed these notes, was a “straw man” and was worthless at the time he obtained the property described in the mortgage that was given to secure these notes; that the property so mortgaged was worth much less than the amount of the notes; that Henry S. Dooley procured said property to be conveyed to Bishop and said notes and mortgage to be executed by him without more than a nominal consideration to Bishop; that Dooley received the benefit from this transaction personally; that these facts were unknown to appellant at the time she purchased the notes, and that she is a bona fide innocent purchaser of said notes for value before maturity; that both J. W. Bishop and Henry S. Dooley are dead; that they died before the maturity of said notes; that Bishop had no property whatever when .he died and that the property of the said Henry S. Dooley has been administered upon and distributed to appellees, who are his heirs, and that none of it is now available for the payment of these notes; that these appellees have each received out of the estate of Henry S. Dooley, deceased, more property than would be required to pay these *160notes; that the inventory filed in his estate did not include all of his property; that more property was omitted from that inventory than would be required to pay these notes and that such property so improperly omitted from such inventory has been divided between these appellees; that appellees have been asked by appellant to pay these notes out of the property of the said Henry S. Dooley, deceased, so received by them and to account therefor, but they refuse, and that appellant has offered in that connection to assign and turn said notes and mortgage over to appellees. The bill prays for an accounting as to the assets received by appellees from the estate of the said Henry S. Dooley, deceased, and that appellees be ordered to pay these notes out of the property so received by them from the said estate. A demurrer to this bill was sustained and the bill was dismissed by the Circuit Court. For the purpose of determining whether the demurrer was properly sustained, the averments in the bill must be treated as true.
From the averments in the bill it follows that Henry S. Dooley, at the time he wrote the guarantee on these notes and turned them over to himself as conservator of Mary A. Brown, knew that they were not good without such guaranty, and that to invest his ward’s money in negotiable paper that he knew was not good would be a fraud upon his ward. He was about to ask the County Court to approve his acts in investing the money of his ward in these notes. He knew that if he procured such an approval of that investment when he knew the notes were not good he would be perpetrating a fraud upon the court. When the acts of men are capable of two constructions, one that they are fair and honest and the other that they are fraudulent and dishonest, courts will adopt the first theory and will not presume a fraudulent purpose. It must therefore be presumed from the facts averred in this bill that when *161Henry S. Dooley placed the guaranty on the notes in question he intended to make them good by placing behind them his own estates, and that he intended the indorsement to be a general unconditional guaranty and did not intend that his liability thereon should depend upon the prosecution of a suit to collect the debt against the maker of the notes whom he knew to be worthless, or the foreclosure of a mortgage that he knew was insufficient security. Such a guaranty must be construed to be and is an unconditional contract, by which the guarantor undertakes to see to it that the note will be paid when due, not that it can be collected by suit or out of some security.
