*291 Cardozo, J.

In 1910 the D’Ambra Construction Company was building apartment houses on One Hundred and Ninety-ninth street and also on Hull avenue in the city of New York. The plaintiff, who was substantially the sole stockholder, was an experienced builder, and had charge of the work. He sought and obtained a building loan contract from the estate of Cornelia B. Kip, represented by its executor, the defendant, Philip Rhine-lander. Ninety-four thousand dollars was to be loaned, forty thousand on one parcel and fifty-four thousand on the other. The mortgages were prepared by one Hartcorn a lawyer. Hartcorn’s firm, the defendant and the Kip Estate had offices in common.

In August, 1911, mechanics’ liens for about $22,000 were filed against the mortgaged parcels. Damage by fire to one of the buildings increased the builder’s complications. The plaintiff was advised by Hartcorn to convey the property to holding corporations organized to receive the title. The defendant, it was said, would advance, not only the moneys called for by the contract, but also whatever other moneys were necessary for the removal of the liens. The plaintiff would continue to manage and supervise the construction, and would be the agent to collect the rents. Compensation would be made to him in one or other of two ways. Either he would receive an assignment of the entire capital stock of the holding corporations, subject only to a mortgage to *292 secure the loans or advances of the defendant and the Kip Estate; or else he would be paid in cash as follows: $25,000 with interest from October 9, 1911, the value of his., own investment in the land; fifteen per cent of the cost of construction for services as supervising builder; and five per cent of the cost for services as manager after the buildings were completed.

The making of some such arrangement by Hartcorn is hardly, if at all, disputed. The litigation turns upon the issue whether he made it in his own behalf or in behalf of the defendant, and if in behalf of the defendant, with the latter’s knowledge and consent. The plaintiff says that the defendant was present at the most important interviews; approved of every promise that was made; and took title in the name of corporations, but in truth as beneficial owner. The defendant denies that he ever heard of the arrangement or of anything like it until some time in 1919, when the action was begun. The theory of the defense is that the promises, if made, were those of Hartcorn personally; that Hartcorn and not the defendant was the owner of the shares in substance as well as in name; that Hartcorn was to receive the profits of the enterprise if successful; and that the defendant had no interest except as mortgagee.

Holding corporations, the Aloha Realty Company and the Narcorth Realty Company, were organized in September, 1911.. The entire stock of both corporations was issued in Hartcorn’s name, with the exception of qualifying shares, which were issued to employees in his office. The property on One Hundred and Ninety-ninth street was transferred to one corporation, and the property on Hull avenue to the other. With the aid of the defendant’s advances, made from the Kip moneys, and of the plaintiff’s supervision, the work was carried to a close.' Another parcel, situated on Villa avenue, was afterwards acquired by the Aloha Realty Company, and the plaintiff again supervised the construction upon the promise of a like *293 reward. The Hull avenue houses were sold in April, 1912. The Aloha Realty Company still holds the title to the others. In March, 1919, upon the defendant’s disclaimer of liability, this action was begun. It is brought upon the theory that the defendant became personally responsible for the payment to the plaintiff of the promised compensation. There was a verdict for $77,064, which, on appeal to the Appellate Division, was unanimously affirmed.

We state the controversy in barest outline. The outline is enough to reveal the ownership of the beneficial interest in the holding corporations as a fact of capital importance to the seeker after truth. The contract had in view an option, which would be exercised one way or the other as there might seem to be a small chance or a large one of profit to the owner. If the chance was small, the shares would be assigned to the plaintiff, subject to a mortgage for the loan. If the chance was large, the shares would be retained as a profitable investment, and the plaintiff would be paid in cash. In any estimate of probabilities, the jury would be likely to conclude that the man who was to profit was the man who was to pay. Upon the crux of the case, the defendant’s participation in the contract, there was oath against oath. Hartcorn, if the real owner, was probably speaking for himself; if the owner in name only, he was probably speaking for another. The touchstone that would bring out the truth was the ownership of the shares.

The plaintiff was alive to the significance of the situation. He was not satisfied to rest upon proof that the shares were in Hartcom’s name. He showed besides that in 1917 or 1918 they were transferred to the defendant. Here unexplained was an admission decisive almost of the controversy. The transfer was put before the jury as the confirmation of an existing title, the recognition of a duty assumed at the beginning. The defendant could hardly hope to prevail unless he broke the force of *294 the admission by some convincing explanation. He was allowed to state in the most general terms that Hartcorn transferred the shares as security for a loan. There was little that was convincing about this statement standing by itself without voucher or document or particulars to confirm it. Confirmation was offered and rejected. The defendant produced a .written' contract between himself and Hartcorn. It is dated May 1, 1918, and is acknowledged the same month. It is an elaborate document covering twenty printed pages. It recites that Hartcorn is the president and the majority or sole stockholder in the Aloha Realty Company and the Narcorth Realty Company, as well as other corporations which it names. It recites a claim on the part of the defendant that Hartcorn is indebted to him individually and as the representative or executor of others. It then describes the property transferred and delivered to the claimant as security for the payment of any moneys found due upon an accounting, and provides that upon such payment the property shall be returned. Included in the security are the shares of the Aloha Realty Company and those of the Narcorth Realty Company, as well as shares of many other corporations engaged in building operations. The contract which thus exhibited the purpose of the transaction was offered in evidence and excluded.

We are unable to sustain the ruling. There was an attempt to charge the defendant with an act in the nature of an admission. The rule is fundamental that he was free to rebut the admission by an explanation of the act (Ferris v. Sterling, 214 N. Y. 249, 254, and cases there cited). The only question is whether there is reasonable ground for the belief that the evidence if accepted would have affected the result. We think its significance, if made clear to the jury, would have been great and perhaps controlling. The plaintiff would have us believe that in the transactions in controversy as well as in many others, Hartcorn was the defendant’s *295 “ dummy,” doing the defendant’s bidding and seeking nothing but the defendant’s profit. The contract which the court rejected leaves us with another picture. The docile and disinterested “ dummy ” is exhibited as an owner in his own right, asserting without protest his title to the shares at the very moment that he subjects them to the burden of a pledge. He is at odds with his client as to many things, but as to his title, not at all. The enterprises conducted by these many corporations are his. He has been managing them for himself, and not as the representative of another. One would have to follow the contract through all its twenty pages to see how that relation emerges as an assumption from beneath its covenants and recitals. The record does not suggest the possibility that covenants and recitals are the product of collusion. Strained relations had developed between the defendant and bis former lawyer, and they were acting at arms’ length. If the jury understood the contract, they could hardly fail to conclude that Hartcorn was in substance as well as in name the owner of the shares. If they found that he was to enjoy the profits, they might find, not unreasonably, that he was to bear the attendant burdens.

The trial judge took the view that the contract should be rejected because the defendant had already been allowed to state that the transfer was accepted to secure the payment of a debt. This is an inadequate reason for the exclusion of evidence so cogent. “ The defendant had a right, * * * to fortify his own testimony in any way that he could ” (Page v. Krekey, 137 N. Y. 307, 316). The writing reinforced and amplified the vagueness of the spoken word. What was said was loose and general, without corroborating circumstance or confirmatory document. Standing alone, it was subject to suspicion as the facile excuse of guilt driven to a corner. Document and circumstance would tell a different tale.

Other objections to the recovery have been argued by *296 appellant’s counsel. The unanimous affirmance at the Appellate Division withdraws them from our power of review.

The judgment of the Appellate Division and that of the Trial Term should be reversed, and a new trial granted, with costs to abide the event.
