In a bill of complaint filed July 13, 1950, Kenneth H. Teeter, plaintiff and appellant, seeks cancellation of a written agreement made on December 9, 1942, with his mother, Edith M. Teeter, defendant, and a discharge of any further liability to her. The agreement provided for a sale of defendant’s interest in a business in which her deceased husband and plaintiff were copartners and which interest she had inherited from her husband. Plaintiff agreed to pay her for her interest the sum of $50 a month until her death and further to provide in his will for the continuance of the payments should he predecease her. Although defendant claimed in a previous action at law that she inherited a f interest, we will assume for the purpose of this-opinion that it was only a i interest, as claimed by plaintiff. The written agreement, executed by both parties, is clear, unambiguous and of such a nature as to be easily and readily understood by a layman of ordinary intelligence. It requires no interpretation from sources other than the instrument itself.

The judge below granted a motion to dismiss the bill of complaint. Therefore, all of the well-pleaded and material allegations of fact in the bill will be assumed to be true in our consideration of the case. Their legal effect, however, is for us to determine.

The main contentions of plaintiff in his bill are as follows:

(a) Plaintiff claims that lie understood at the time of making the agreement that a later agreement would be made by way of evaluating defendant’s interest and determining just how much should be paid for it; that his understanding that his liability to defendant would not extend beyond the fair valuation of her interest in the business was the inducement to his entering into the contract. There is nothing in the written agreement that sustains this claim or the others hereinafter referred to. Misunderstanding by the plaintiff alone does-not present a reason for the intervention of a court of equity. Mutual mistake or fraud must be the basis of the cancellation sought by plaintiff and neither is shown in the bill. "'Plaintiff does not allege that the misunderwas mutual. Neither is there an allegation that his misunderstanding resulted from the acts of defendant or her attorney, by misrepresentation or otherwise. Indeed, plaintiff avers in his bill that the agreement was designed “primarily for the assistance and support of defendant,” a purpose not consistent with an intent to stop payments at any time before the death of defendant.

(b) Plaintiff further claims that his misunderstanding was caused by the defendant, since at the time of the agreement defendant was represented b3 an attorney and plaintiff was not. The agreement was not of a complex nature, the type that requires the services of an attorney to understand. There is no allegation that defendant employed an attorney for the purpose of misleading plaintiff, or that the ^attorney misled him.

(c) Plaintiff also claims that by July, 1949, he had paid complete consideration for the value of defendant’s interest in the copartnership, and that to require him to pay any further sum would be inequitable and result in an inadequacy of consideration by defendant. However, there is no inadequacy of consideration here that would justify the interposition of a court of equity. Plaintiff seeks to escape an unprofitable bargain. If defendant had died shortly after the agreement was entered into, or if the business under plaintiff’s management had become very profitable, he would have made an extremely favorable bargain. There is no allegation that the agreement was not a fair one at its inception; it cannot be attacked because the plaintiff 7 years later feels he agreed to pay too large a sum.

(d) By way of relief, plaintiff wishes to affirm his contract up to 1949, but to have the operation of the instrument declared legally fraudulent and void and cancelled from that time on; or, as he states in the bill of complaint, “that the enforcement of the said agreement should be confined to the consideration as understood and interpreted by the plaintiff herein at the time he placed his signature on said instrument.” Plaintiff thereby seeks to affirm the contract in its operation up to 1949 and to declare its operation subsequent thereto completely void. This cannot be done. In the guise of reformation or cancellation, we have no power in equity to make a new contract for the parties. Wood v. Truax, 39 Mich 628; Nash v. Burchard, 87 Mich 85; Amick v. Hickey, 254 Mich 37; Engel v. State Mutual Rodded Fire Ins. Co., 257 Mich 245; Goldberg v. Cities Service Oil Co., 275 Mich 199; E. R. Brenner Co. v. Brooker Engineering Co., 301 Mich 719.

In his brief on appeal, plaintiff-appellant argues that the trial court erred in declaring on its own motion that the bill of complaint stated no cause of action. The trial court, although admitting that such reason as a reason for dismissal does not appear in the written motion on file, stated, “it is the court’s duty to raise jurisdictional matters upon its own motion if they have not been raised by counsel.”

See, to that effect, Bradley v. Board of State Canvassers, 154 Mich 274; In re Estate of Fraser, 288 Mich 392; Lehman v. Lehman, 312 Mich 102. Plaintiff does not deny that this is the correct rule, but contends that there was nothing on the face of the bill or the pleadings in the cause to show a lack of jurisdiction as such. As has been stated heretofore, however, we find nothing on the face of the pleadings to justify the interposition of a court of equity. In the absence of such a showing, the court lacked equitable jurisdiction and properly dismissed the bill on its own motion. In any event, this is an equity case which we hear de novo and we find, upon reading the record, that the bill of complaint should have been dismissed.

We find no other claims that merit further discussion. On motion, the trial judge entered an order dismissing plaintiff’s bill of complaint. The order is affirmed, with costs to defendant.
