WILKINS, C.J.
In M. DeMatteo Constr. Co. v. Daggett, 341 Mass. 252, which was a bill in equity for specific performance of an agreement by the defendant dated February *578 7, 1957, to sell a large tract of marshland in Revere and Saugus, there was a decree for the plaintiff. In this action of contract by a real estate broker for a commission on the sale, there are two counts. On the first count, on an express contract to pay the usual broker's commission for procuring a customer, there was a verdict for the defendant. On the second count, on an account annexed for services rendered in procuring a customer, there was a verdict for the plaintiff for $32,500. The defendant's exceptions which we find it necessary to consider are (1) to the allowance of the plaintiff's motion to strike a part of the defendant's answer setting up the defendant's mental incapacity, and (2) to the denial of his motion for a directed verdict. We consider them in inverse order.
1. The one ground upon which the defendant contends his motion for a directed verdict should have been granted is that the action was prematurely brought. The writ in the present action is dated August 19, 1957, ten days later than the filing of the bill in equity. The equity suit was based upon a written contract dated February 7, 1957, between M. DeMatteo Construction Company (DeMatteo) and Daggett. The bill of exceptions in the present action states that the judge at the trial treated count 1 as referring to that contract (exhibit 3), which contained a paragraph reading: "XI. A commission is to be paid upon the passing of papers by the seller to the broker herein, Gerald M. McCarthy of Saugus, Massachusetts, in an amount as agreed upon between the seller and said broker." Following the signatures of the parties at the end appeared the following: "I hereby assent to the provisions of paragraph #11. [Sgd.] Gerald M. McCarthy." Exhibit 3 also provided for the delivery of the deed on May 7, 1957, "unless otherwise agreed upon in writing," but no deed was in fact delivered until August 15, 1960, and then as a result of the final decree in the suit in equity. The defendant nowhere contends that the plaintiff was not the efficient cause of the sale, and there was evidence warranting the jury in finding that he was. See Fitzpatrick v. Gilson, 176 Mass. 477, 478-479; *579 Driscoll v. Bunar, 328 Mass. 398, 400; MacDonald v. Mihalopoulos, 337 Mass. 260, 262.
The argument as to prematurity of suit is specious. Recovery on count 2 in quantum meruit, accompanied by the verdict for the defendant on count 1, put the express contract out of the case. Its provisions now relied upon fell with it. The provision as to payment "upon the passing of papers," even where applicable, does not necessarily create a condition precedent to payment, but may specify a time beyond which the broker is not to be kept waiting for his commission. See Alvord v. Cook, 174 Mass. 120, 124; Rosenthal v. Schwartz, 214 Mass. 371, 373; Canton v. Thomas, 264 Mass. 457, 459. Compare Spritz v. Brockton Sav. Bank, 305 Mass. 170, 171; E.A. Strout Realty Agency, Inc. v. Gargan, 328 Mass. 524, 527.
2. The second paragraph of the defendant's answer set up that "at the time of the alleged employment referred to in the plaintiff's declaration the plaintiff [sic] was insane and incapable of entering into any legal and binding agreement, wherefore the defendant owes the plaintiff nothing." See Lewis v. Russell, 304 Mass. 41, 43. At the trial the plaintiff filed a written motion "to strike paragraph 2 of the defendant's answer setting forth insanity on the part of the defendant, on the ground that this issue was fully tried before the Superior Court and the Supreme Judicial Court and was decided in the case of M. DeMatteo Construction Co. v. Dewey E. Daggett." When first presented, the motion was denied, but on the following day it was allowed by the judge.
The plaintiff contends that the defendant is barred from raising the issue of mental incapacity because of "(1) res judicata and (2) the doctrine of collateral estoppel by judgment." This is called "collateral estoppel" in Restatement: Judgments, § 68, comment a. In Wishnewsky v. Saugus, 325 Mass. 191, 194, cited by the plaintiff, the term used is "estoppel by judgment." We note in passing that there is a question whether the issue in the case at bar is the same as in the DeMatteo case. Here the time of employment *580 as broker is given in the declaration and in the plaintiff's testimony as in November, 1956. The written contract with DeMatteo was dated February 7, 1957. In the DeMatteo case the decision was on the written contract. Here the recovery is in quantum meruit.
The fatal flaw in the plaintiff's argument is the assumption that the plaintiff and the defendant "are parties in privity with respect to the contract and the defendant's capacity to enter the same." Paragraph XI does not have that effect. The plaintiff was not a party and could not have insisted on being made a party to the earlier case. He would not have been bound by a determination that Daggett was incompetent and cannot take advantage of a determination that he was competent. Brigham v. Fayerweather, 140 Mass. 411, 414-415. Old Dominion Copper Mining & Smelting Co. v. Bigelow, 203 Mass. 159, 217. McCarthy v. William H. Wood Lumber Co. 219 Mass. 566, 571. Cleaveland v. Malden Sav. Bank, 291 Mass. 295, 298. He was not the agent of Daggett. See Giedrewicz v. Donovan, 277 Mass. 563. He did not control the suit or have a proprietary interest in it. Pioneer Insulation & Modernizing Corp. v. Lynn, 331 Mass. 560, 563-564.
The plaintiff suggests that the DeMatteo case adjudicated the status of the capacity of the defendant to enter into a binding contract, and that that status should stand against the world as in the nature of a proceeding in rem. This we reject. An adjudication of insanity is not conclusive upon all the world as an adjudication of the facts upon which it is grounded. Brigham v. Fayerweather, supra, 413. Boston Safe Deposit & Trust Co. v. Bacon, 229 Mass. 585, 589. Freeman, Judgments (5 ed.) §§ 900, 901.
Exceptions sustained.
