Before MARKEY, P.J., and JANSEN and ZAHRA, JJ.
MARKEY, Presiding Judge.
Defendant Indiana Insurance Company[1] appeals by right the trial court's order of *234 judgment entered after a jury trial in this action to enforce a settlement agreement and the order denying its motion for judgment notwithstanding the verdict (JNOV) or a new trial.
This case has a long history that began with a 1984 automobile accident that occurred in an area of road construction. The guardian of the victim of that accident subsequently brought suit against the Michigan Department of Transportation (MDOT) and its contractor on that construction job, Spartan Asphalt Paving. Both MDOT and Spartan settled their cases with the victim's guardian.
MDOT settled its case for $825,000. MDOT's insurance carrier, Indiana Insurance Company, paid its policy limit of $500,000, and MDOT paid the additional $325,000. MDOT then brought suit against Spartan for indemnity and contribution. The lower court in the indemnity case granted summary disposition in favor of MDOT. This Court affirmed that decision,[2] and our Supreme Court denied leave to appeal.[3]
After this Court affirmed the lower court's decision, Spartan and its insurance carrier, Michigan Mutual Insurance Company, brought this suit against defendant, claiming that the two insurance companies had a settlement agreement in the amount of $450,000 and that plaintiffs' payment should be limited to that amount instead of the full $825,000 plus interest. The agreement was based on telephone conversations between adjusters from both insurance companies. Those conversations took place after summary disposition had been granted to MDOT regarding indemnity, but before this Court heard that case on appeal. During the course of the adjusters' discussions, defendant's adjuster forgot about MDOT's payment over and above the $500,000 policy limit that defendant paid. After numerous conversations discussing possible settlement amounts, the adjusters agreed on $450,000. Defendant's adjuster recorded that agreement with this notation in his activity log: "6-5-95 Settled for $450."
Following this Court's decision in the indemnity suit, plaintiffs brought this action against defendant in an effort to recover amounts paid in excess of the $450,000 settlement amount. The parties moved for summary disposition before and after discovery, and all motions were denied. The parties' motions for a directed verdict also were denied. A jury found that the adjusters' conversations formed a contract, defendant breached that contract, and plaintiffs sustained damages in the amount of $720,960. Subsequently, defendant moved for JNOV or a new trial, and the circuit court denied that motion. Defendant now appeals.
Defendant argues that this case involves an agreement to settle; therefore, it must comply with MCR 2.507(H) to be enforceable. We agree. Interpretation of a court rule is subject to review de novo on appeal. St George Greek Orthodox Church of Southgate, Michigan v. Laupmanis Associates, PC, 204 Mich.App. 278, 282, 514 N.W.2d 516 (1994).
MCR 2.507(H) provides as follows:
An agreement or consent between the parties or their attorneys respecting the proceedings in an action, subsequently denied by either party, is not binding unless it was made in open court, or *235 unless evidence of the agreement is in writing, subscribed by the party against whom the agreement is offered or by that party's attorney.
MCR 2.507(H) has been characterized as "essentially a court rule version of a statute of frauds governing legal proceedings." 3 Martin, Dean & Webster, Michigan Court Rules Practice (3d ed), p 125. As noted by the commentators:" Legal proceedings are of sufficient importance to require that written proofs be furnished in support of a claim by one party that the other party has entered into certain agreements, made certain concessions, etc. with respect to those proceedings." Id. Thus, just as an oral agreement for the sale of real property, for example, is unenforceable under M.C.L. § 566.108; MSA 26.908 even though that agreement may meet the technical requirements of a contract, an oral settlement agreement in a lawsuit is also unenforceable under MCR 2.507(H) unless it is reduced to a signed writing or made in open court. [Brunet v. Decorative Engineering, Inc., 215 Mich.App. 430, 435-436, 546 N.W.2d 641 (1996).]
In addition to the court rule, case law holds that "[a]n agreement to settle a pending lawsuit is a contract and is to be governed by the legal principles applicable to the construction and interpretation of contracts." Walbridge Aldinger Co. v. Walcon Corp., 207 Mich.App. 566, 571, 525 N.W.2d 489 (1994). However, this Court will not enforce a settlement agreement that fulfills the requirements of contract principles if that agreement does not also satisfy the requirements of the court rule. Metropolitan Life Ins. Co. v. Goolsby, 165 Mich.App. 126, 128-129, 418 N.W.2d 700 (1987).
In Goolsby, supra at 128, 418 N.W.2d 700, this Court had "no difficulty accepting the trial court's factual conclusion that appellees made an offer which appellant ... authorized her attorney to accept and which was accepted by her attorney." This Court concluded, however, that despite the agreement, the court rule was controlling, and the agreement was unenforceable because it was not made in open court or in writing. Id. at 128-129, 418 N.W.2d 700. Similarly, in this case, even though the jury determined according to contract principles that the parties entered into a contract, because the contract was for the settlement of pending litigation, it must also meet the requirements of MCR 2.507(H).
Plaintiffs also argue that MCR 2.507(H) requires that defendant deny the agreement for it to fail and that defendant here never denied that the parties had reached a settlement agreement. We disagree.
Because MCR 2.507(H) does not define "denied," we may consult a dictionary for guidance. Richards v. McNamee, 240 Mich.App. 444, 451, 613 N.W.2d 366 (2000). As it relates to law, a "denial" is the "refusal to acknowledge the validity of a claim, suit, or the like...." Random House Webster's Unabridged Dictionary (1998). In this case, even though defendant acknowledges the conversations between the adjusters, it argues that those conversations are not enforceable because MDOT did not consent to the agreement, i.e., to give up its right to recoup its disproportionate payment of the settlement. We find that defendant's claim of invalidity is equivalent to a denial. Therefore, we must examine whether the other requirements of the court rule were met.
In the present case, the settlement offer and acceptance were not made in open court. Therefore, to be enforceable, there must be a writing subscribed to by defendant or its attorney. Previously, this Court has found that a letter signed by a party's attorney satisfied the writing requirement of this rule. Walbridge, supra. *236 Additionally, this Court has found that a copy of a proposed agreement signed by the party then claiming that there were conditions precedent met the requirements of MCR 2.507(H). Reed v. Citizens Ins. Co. of America, 198 Mich.App. 443, 447-448, 499 N.W.2d 22 (1993).
The writing in the present case consisted of a few-word notation in the activity log of defendant's adjuster. This terse notation is distinguishable from both an attorney-signed letter and a party-signed proposal. We conclude that the writing in this case does not rise to a level sufficient to satisfy the writing requirement of MCR 2.507(H). Therefore, this agreement is unenforceable.
In light of our disposition of the above issue, defendant's remaining issue need not be discussed.
We reverse and remand for entry of a judgment in favor of defendant. We do not retain jurisdiction.
