[1] The defendants first contend that the trial court erred in ruling that the contract between defendants Pell and Needham and plaintiff Bank did not include a condition precedent to the guaranty that the plaintiff must first obtain the valid signatures of all the other named defendants before the guaranty would be effective. We agree with plaintiff.
The trial court found as fact the following:
(2) Shortly before February 15, 1977,. the defendants, Phillip H. Pell and O. M. Needham, Jr., informed R. W. Smith, Vice-President of Farmers Bank, that they wished to sell their stock in the corporation to Michael T. Brown, and inquired whether the bank would continue to extend its previous line of credi(t to the corporation under the new stockholder, if the new stockholder, Michael T. Brown, his wife, Brenda M. Brown, and his mother-in-law, Vida M. Mc-Canless, signed the corporate notes as makers, and if the defendants, Phillip H. Pell and O. M. Needham, Jr., signed a guaranty of payment of such indebtedness. R. W. Smith informed the defendants, Phillip H. Pell and O. M. Needham, *316Jr., that the bank would continue to extend credit under such arrangement.
(3) On or about February 15, 1977, the bank prepared a new note in the amount of Seventy-Five Thousand Dollars ($75,000.00) to consolidate old notes signed by corporate officers. The new note was signed by officers of the corporation and by Michael T. Brown (Individually) in the presence of R. W. Smith. Michael T. Brown then took the note from the bank to have it signed by Brenda M. Brown and Vida M. Mc-Canless. Michael T. Brown later returned the note to the bank bearing the purported signatures of Brenda M. Brown and Vida M. McCanless.
(4) As a part of this same transaction, the defendants, Phillip H. Pell and O. M. Needham, Jr., signed a loan guaranty agreement on February 14, 1977, jointly and severally guaranteeing full and prompt payment of any indebtedness of Ned-Pell Distributors, Inc., to Farmers Bank, to the extent of Seventy-Five Thousand Dollars ($75,000.00), plus interest, and all costs, expenses and reasonable attorney’s fees incurred in endeavoring to collect said indebtedness or in enforcing the guaranty agreement.
The court further concluded as a matter of law “[t]hat valid signatures of Brenda M. Brown and Vida M. McCanless as comakers or endorsers of the note were not a condition preceding which was communicated to the plaintiff so as to make the plaintiff responsible for obtaining these signatures and insuring their validity.” The defendants except to this conclusion of law.
It is well settled in North Carolina that when the parties waive a trial by jury the duty falls upon the trial court to find the facts and the law in the case. The resolution of conflicting evidence is a matter for the court, and when the evidence is sufficient to support the findings and when error of law does not appear upon the face of the record proper, the court’s findings of fact have the force and effect of a verdict by a jury and are conclusive on appeal. See Distributing Corp. v. Schofield, 44 N.C. App. 520, 261 S.E. 2d 688 (1980); Fletcher v. Fletcher, 23 N.C. App. 207; 208 S.E. 2d 524 (1974). The appellate court is bound by these findings where there is some testimony to súpport them, even if there is evidence to the contrary that would support a dif*317ferent finding. Williams v. Insurance Co., 288 N.C. 338, 218 S.E. 2d 368 (1975). In this case there was evidence consisting of Mr. R. W. Smith’s testimony to support the court’s finding that defendants told Smith that they would sign a guaranty in addition to the other signatures on the corporate note. This in turn supported the trial court’s conclusion of law that the valid signatures of Brown and McCanless on the note were not a condition precedent to defendants’ liability. Thus defendants’ assignments of error are without merit and are overruled.
[2] The defendants next argue that if there was no condition precedent then there was no meeting of the minds and thus, no contract of guaranty between plaintiff and defendants Pell and Needham. To constitute a valid contract, the parties must assent to the same thing in the same sense. The agreement, however, controls and not what either party thought the agreement to be. A party to a contract cannot avoid it on the ground that he made a mistake where there has been no misrepresentation, there is no ambiguity in the terms of the contract, and the other contractor has no notice of such mistake and acts in good faith. 3 Strong’s N.C. Index 3d Contracts § 2 (1976).
In the present case, the court found that the guaranty agreement executed by defendants Pell and Needham was a guaranty of payment. The court also concluded that there were no oral conditions precedent to the guaranty agreement. The written guaranty sets forth the agreement in clear and unambiguous language and the defendants are bound by those terms. Thus this assignment of error is without merit and is overruled.
We have carefully considered the defendants’ remaining assignment of error that the trial court’s judgment is not supported by the evidence. This assignment of error is without merit and is overruled.
The judgment of the trial court is
Affirmed.
Judges Vaughn and Arnold concur.
