ON PETITION FOR TRANSFER
We hold that an order directing the parties to consummate a mediation settlement agreement, without more, is not a final judgment, and that an attorney attending a mediation settlement conference may bind the client to a settlement agreement despite the client’s absence.
Factual and Procedural Background
Claude Jackson was injured in a collision with a truck driven by Michael Georgos, an employee of Pangere Corporation, and sued both Georgos and Pangere (collee- *450 tively “Defendants”). 1 The trial court ordered mediation. Although the order does not appear in the record, it is clear that the mediation was to be conducted under the Indiana Alternative Dispute Resolution Rules. Rule 2.7(B)(2) provides:
All parties, attorneys with settlement authority, representatives with settlement authority, and other necessary individuals shall be present at each mediation conference to facilitate settlement of a dispute unless excused by the court.
Jackson did not appear at the mediation. No party contends that his attendance was excused by the trial court. His attorney and an attorney representing both Defendants were present. Jackson’s attorney stated at the mediation that he had the authority to settle, and Jackson has never disputed that this authority existed as of that time. The mediation resulted in a document signed by both attorneys and the mediator. It reads in its entirety:
CONFIDENTIAL
MEDIATION SETTLEMENT AGREEMENT
Come now the parties, by counsel, for mediation on November 2,1998. Mediation of the claims resulted in the following settlement:
1. Defendants’ insurer will pay the plaintiff $94,500.00 in exchange for a full release.
2. Plaintiff agrees to be responsible for all liens.
3. Costs of mediation will be shared equally by the parties.
/s/ Frederick J. Ball Attorney for [Defendants]
/s/ Robert L. Lewis Attorney for [Jackson]
/s/ Daniel W. Glavin, Mediator Date: November 2,1998
The mediator reported to the court that the case had been settled. At the time of the mediation Jackson had already incurred medical expenses of approximately $85,000.00. At some point after the mediation Jackson advised the Defendants that he had repudiated the settlement. The Defendants then filed a “Motion to Enforce Mediation Settlement Agreement.” Jackson responded that at the time of the mediation both he and his attorney had believed that the limit on the policy covering the Defendants was $100,000 but they had subsequently learned that the limit was $1 million. Based on this factual predicate, Jackson asserted a variety of legal theories (fraud, mistake, etc.) he contended warranted voiding the settlement agreement.
On August 2, 1999, the trial court granted the Motion to Enforce, but did not dismiss the complaint. Apparently treating the grant of the motion as a final judgment, almost five months later, on December 31,1999, Jackson filed a Trial Rule 60(B)(8) “Motion for Relief from Judgment,” asserting that because ADR Rule 2.7(B)(2) required the parties as well as the attorneys to be present at a mediation, any agreement reached in the absence of the parties was a nullity. The trial court agreed with Jackson and on February 22, 2000, granted Jackson’s motion for relief from judgment. The case went to trial and on April 9, 2001, the jury returned a verdict for Jackson in the amount of $462,000. The Defendants appealed, as *451 serting among other things that the trial court lacked jurisdiction to grant the “Motion for Relief from Judgment” because it was filed too late to be granted as a motion to correct errors or for reconsideration of a final judgment, and, if viewed as a Trial Rule 60 motion, stated no ground for relief under that rule. 2
The Court of Appeals reversed. The Court of Appeals first held that the August 2 order enforcing the settlement agreement was a final judgment. Accordingly, the Court of Appeals reasoned that the trial court lost jurisdiction over the case after thirty days when the time for appeal or a motion to correct errors lapsed on September 1, 1999. The Court of Appeals also held that Jackson’s Trial Rule 60 motion was improperly granted because it raised no facts not known at the time of the August 2 order. As a result, the dispute was resolved by the August 2 order, and the Court of Appeals ruling reinstated the order granting the Motion to Enforce. This Court granted transfer on July 19, 2002. For the reasons given below, we reach the same result as the Court of Appeals, but for different reasons.
I. Appealability of Order Enforcing Settlement Agreement
The Court of Appeals concluded that the grant of the Defendant’s Motion to Enforce Mediation Settlement Agreement was appealable as a final judgment and also under Trial Rule 54(B). For the reasons given below, we conclude it was neither.
Succinctly stated, a final judgment “disposes of all issues as to all parties thereby ending the particular case.”
Doperalski v. City of Michigan City,
Both the parties and the trial court treated Jackson’s motion for relief from judgment as properly filed under Trial Rule 60(B)(8). The Court of Appeals concluded that because the parties and the trial court treated the trial court’s August 2 order as a final judgment, whatever defects existed in the ruling as a final judgment were cured. We do not agree that the views of the parties or the trial court resolve this issue. Whether the order was a final judgment governs the appellate courts’ subject matter jurisdiction, and unlike most contentions, lack of jurisdiction is not waived by the parties. Neither the parties nor the trial court can confer appellate jurisdiction over an order that is not appealable either as a final judgment or under Trial Rule 54(B). To the contrary, the lack of appellate jurisdiction can be raised at any time, and if the parties do not question subject matter jurisdiction, the appellate court may consider the issue sua sponte.
Albright v. Pyle,
The trial court’s grant of the Motion to Enforce was not a final judgment because it did not end the ease. The relief requested by the Defendants was that the trial court uphold the validity of the settle *452 ment, and order Jackson to enter into a joint stipulation of dismissal. By its terms, the motion asked the trial court to order Jackson to sign the settlement agreement, which had already been signed by his attorney, and asked that the trial court order the Defendants to pay Jackson the agreed amount. In granting the Defendant’s motion, the trial court order directed Jackson, “to take all measures necessary to consummate the settlement ... within 30 days.” This did not dismiss the case, and left open what would happen if, as in fact turned out to be the case, Jackson did not comply with the directive to consummate the settlement.
A disposition of all claims requires more than the entry of a ruling on a motion without entry of judgment.
See Constantine v. City-County Council of Marion County,
The Court of Appeals concluded that even if the August 2 order was not a final judgment it met the requirements of an order appealable under Trial Rule 54(B) because “had it been carried out, [it] would have led to the entry of an ultimate determination ... between Jackson and the Appellants.”
Georgos v. Jackson,
Even though the trial court’s August 2, 1999, ruling granting the Defendants’ Motion to Enforce was an interlocutory order, it was arguably appealable as of right under Appellate Rule 14(A)(2) because it required the execution of a document. However, there is no requirement that an interlocutory appeal be taken, and Jackson may elect to wait until the end of litigation to raise the issue on appeal from a final judgment.
In re Newman,
For all of these reasons, the August 2, 1999, order was not required to be appealed and the issues Jackson raises are prop *453 erly before us in this appeal from the final judgment entered after the jury trial.
II. The Effect of Mediation Settlement Agreement
Jackson does not argue that his attorney lacked the actual authority to enter into a settlement at the mediation. Rather he contends that ADR Rule 2.7(B)(2), which requires the parties to be present at a mediation, rendered unenforceable any settlement in Jackson’s absence. We agree that the rule required Jackson’s presence, but do not agree that his absence invalidates his attorney’s agreement to settle the case.
In
Koval v. Simon Telelect Inc.,
Indiana strongly favors settlement agreements.
Scott v. Randle,
If an agent of a disclosed ... principal makes an authorized contract with a third person, the liability of the principal thereon depends upon the agreement between the agent and the other party as to the parties to the transaction.
Restatement (Second) of Agency, § 146 (1958). The Restatement further states that “[u]nless otherwise agreed, a disclosed ... principal is a party to a contract ... made by his agent within his authority.” Id. at § 147. In this ease it is undis *454 puted that Jackson’s attorney had the authority to settle, and of course Jackson, the principal, was disclosed.
Jackson contends that an attorney’s authority to bind 'the client to a settlement agreement is nevertheless constrained by ADR Rule 2.7. He1 contends that ADR Rule 2.7(B)(2) invalidates settlements entered into under mediations pursuant to ADR Rules if a party is not present and refuses to sign an agreement reached by the party’s authorized attorney. We do not agree that Rule 2.7 suggests that result. The purposes of the requirement that parties and their attorneys be present at a mediation are several fold. They include assuring that the authority to settle is available at the mediation, but they also include facilitating settlement by creating an environment where the parties and their attorneys hopefully receive and appreciate the points of view of the other parties and the mediator. ADR 2.1 (role of mediator is to assist parties in “exploring areas of compromise, and finding points of agreement ....”);
State v. Carter,
Jackson also challenges the validity of the agreement because it was not signed by the parties. ADR Rule 2.7(E)(2) states that “[i]f an agreement is reached, in whole or in part, it shall be reduced to writing and signed by the parties and their counsel.” This Court has emphasized the importance of reducing any agreement reached to a signed written agreement. In
Vernon v. Acton,
Requiring written agreements, signed by the parties, is more likely to maintain mediation as a viable avenue for clear and enduring dispute resolution rather than one leading to further uncertainty and conflict. Once the full assent of the parties is memorialized in a signed written agreement, the important goal of enforceability is achieved.
Id.
at 810. The requirement of signature by the attorneys and parties is designed to avoid disputes over what was or was not agreed to at the mediation. Subsequent cases interpreting
Vernon
have reached the same conclusion.
Spencer v. Spencer,
The Rule’s provision that the agreement is to be signed by both the attorney and the party is consistent with the requirement of ADR Rule 2.7(B) that both the attorney and the party are to be present. Nevertheless, where the agent of the party is cloaked with the authority to enter into the settlement agreement, and the party’s presence is unexcused, the attorney’s signature is sufficient. To hold otherwise would give an incentive to frustrate the mediation by boycott in hopes of renegotiating after the mediation in return for the signature of the absent party. That action would of course be sanctiona-ble under ADR Rule 2.10, so it is not risk-free. But we see no reason to reward or create an incentive to disregard the rules by permitting the improperly absent party, Jackson, to turn his absence to his advantage. In any event, it seems that Jackson’s presence at the mediation would have made no difference. At that time both Jackson and his attorney were under the impression that the policy limit was $100,000. Jackson offers no reason to believe that had Jackson been present at the mediation there would have been no agreement, or that he would not have signed the written settlement agreement along with his attorney.
We recognize that enforcing the settlement agreement gives Defendants’ insurer a windfall due to opposing counsel’s misunderstanding as to the applicable insurance limits. In this appeal the only issues raised are the effect of Jackson’s absence from the mediation. We are not presented in this appeal with the contentions Jackson advanced in the trial court for avoiding the agreement based on that misunderstanding. We note, however, that because the August 2 order was not a final judgment, Defendants are not correct that any motion for “reconsideration”

needed to be filed within thirty days.
Hubbard v. Hubbard,
In sum, we hold that when an attorney attends a mediation under the ADR Rules and executes a settlement agreement, that is sufficient to bind the client who fails to attend without excuse.
Conclusion
This case is remanded to the trial court with instructions to enter judgment pursuant to the terms of the settlement agreement.
Notes
. This suit was originally filed by Luther Stewart, a passenger in Jackson’s car. Stewart filed a complaint against Georgos, Pan-gere, and Jackson, and Jackson cross-claimed against Georgos and Pangere. Stewart then settled his claim, and is not a party to this appeal. The cross-claim by Jackson against Georgos and Pangere remains.
. The appeal also contends the jury verdict was excessive, and that the trial court abused its discretion by allowing an undisclosed expert witness to testify.
. We understand this contention to be based on Trial Rule 59 and the time constraints applicable to a motion to correct errors. Defendants cite
