OPINION
EASTAUGH, Justice.I. INTRODUCTION
Plaintiff filed three state and federal lawsuits against his former employer. After the first two actions were dismissed, the superior court dismissed his third, holding it was barred by res judicata and the judicial policy against claim splitting. Plaintiff appeals. Because the stipulated terms of the dismissal in the first state court action preserved the plaintiffs non-federal claims, neither res ju-dicata nor the doctrine against claim splitting bars the third action. We therefore vacate the dismissal order in the third action and remand for further proceedings.
II. FACTS AND PROCEEDINGS
Daniel DeNardo filed three state and federal lawsuits against his former employer, Alaska Newspapers, Inc., (ANI) and its majority shareholder, Calista Corporation. ANI had employed DeNardo as an advertising sales representative from October 1999 until his termination in July 2000. It is the superior court’s dismissal of the last-filed of these three lawsuits, on grounds of res judi-cata and the policy against claim splitting, that leads to this appeal.
First lawsuit. DeNardo filed his first lawsuit against ANI, Calista, and eight former co-workers in state superior court in July 2000. His complaint in Case No. 3AN-00-8753 Cl alleged numerous claims, including breach of contract, retaliation for filing claims with the Department of Labor and the Equal Employment Opportunity Commission, and negligent and intentional infliction of emotional distress based on harassment by, and favoritism toward, some of ANI’s female employees. DeNardo amended his complaint on August 7, 2000, but the changes are not material for purposes of this appeal.
Second lawsuit. In October 2000 DeNar-do filed his second lawsuit against Calista and ANI. He brought this action in federal court in Case No. A00-309-CV, and based his claims on the same facts asserted in his state court action. The federal complaint alleged state law claims of negligent and intentional infliction of emotional distress and federal law claims of gender discrimination and sexual harassment under 42 U.S.C. § 2000(e)-2000(e)(17) (Title VII).
Calista and ANI removed Case No. 3AN-00-8753 Cl, the state court action, to federal court in November 2000, where it became Case No. A00-351-CV; in December defendants moved for consolidation of the two federal cases. United States District Judge H. Russel Holland ordered consolidation, but in April 2001 remanded Case No. A00-351-CV to state court while retaining jurisdiction over Case No. A00-309-CV.
Following this remand, DeNardo offered to dismiss his now-remanded state court action, Case No. 3AN-00-8753 Cl. The defendants accepted his offer, and on April 27, 2001, the parties signed a three-paragraph stipulation prepared by defense counsel for dismissal of Case No. 3AN-00-8753 Cl with prejudice.1 In May 2001 Superior Court Judge Elaine M. Andrews signed defense counsel’s proposed order granting “the Stipulation to Dismiss With Prejudice.”
Calista and ANI then moved for dismissal of the remaining federal action, Case No. A00-309-CV, contending that as tribal entities they could not be sued under Title VII, *329because neither was an “employer.” The United States District Court granted their motion in November 2001. Judge Holland’s memorandum dismissal order stated, however, that because the court had no original jurisdiction over the Title VII claim, it “declines to exercise supplemental jurisdiction over plaintiffs state law claim for the infliction of emotional distress.” The order also stated that it “is without prejudice to pursuit of any state law claims plaintiff may have in state court.” The United States Court of Appeals for the Ninth Circuit affirmed the dismissal in 2002.
Third lawsuit. In December 2001, after his first state action and his federal action were dismissed, DeNardo commenced his third lawsuit by filing a superior court complaint in Case No. 3AN-01-12484 Cl against Calista and ANI. This complaint was based on the same facts alleged in the first state court action. It expressly asserted a claim of discrimination by Calista and ANI against him in violation of AS 18.80. It indirectly asserted claims of negligent and intentional infliction of emotional distress.
Calista and ANI moved to dismiss Case No. 3AN-01-12484 Cl on the basis of res judicata and the doctrine against claim splitting. Superior Court Judge Phillip R. Vol-land granted their motion on those grounds. DeNardo requested withdrawal of the dismissal stipulation filed in Case No. 3AN-00-8753 Cl, but the superior court denied his request. DeNardo appeals the court’s dismissal of Case No. 3AN-01-12484 Cl and its denial of his request to withdraw his dismissal stipulation in Case No. 3AN-00-8753 CI.
Unless context dictates otherwise, we refer collectively to the appellees as “Calista.”
III. DISCUSSION
A. Standard of Review
Whether res judicata applies is a question of law, an issue that we review de novo.2 We interpret stipulations using the rules of contract interpretation.3 We review the interpretation of contracts, and thus stipulations, de novo.4
B. Res Judicata Does Not Bar DeNar-do’s Claims of Negligent Infliction of Emotional Distress, Intentional Infliction of Emotional Distress, and Discrimination.
The parties disagree about whether the dismissals entered in DeNardo’s two previous lawsuits bar his third lawsuit. Resolution of this issue requires us to consider the effect of the superior court dismissal stipulation and the federal court dismissal order.
1. Parties’ contentions
DeNardo argues that a stipulation will not be construed to give effect to a waiver of a right not plainly intended to be relinquished.5 He argues that a stipulation must be construed according to the parties’ intention as expressed in the document’s language.6 De-Nardo contends that the dismissal stipulation’s terms preserved the discrimination claim regardless of which court had jurisdiction over it. He argues that the federal court dismissed the discrimination claim because it lacked jurisdiction; he contends that jurisdictional dismissals have no res judicata *330effect.7 He also seems to argue that his first state action did not include a discrimination claim under AS 18.80 and that therefore the dismissal in his first state court action cannot bar his current discrimination claim.
Calista argues that under the doctrine of res judicata, dismissal of the first state lawsuit bars the present lawsuit. It asserts that all elements are present to give res judicata effect to the stipulated dismissal. It states that a dismissal entered pursuant to a stipulation for dismissal of claims with prejudice has the same res judicata effect as a final judgment entered after trial.8 It therefore contends that the order granting the stipulation to dismiss with prejudice is a final judgment for res judicata purposes. It also argues that the superior court in the first state action had jurisdiction and that the same parties are involved in both state actions. Calista argues that DeNardo does not dispute that he could have asserted a claim for discrimination under AS 18.80.220 in his first action. It therefore reasons that the stipulated dismissal resolved not only the claims specifically brought, but also the claims De-Nardo could have brought under AS 18.80.220.9 It also argues that we should not permit DeNardo to prolong this litigation by splitting his claim.10
2. DeNardo’s prior claims and the stipulated dismissal
DeNardo’s original and amended complaints in his first state court action, Case No. 3AN-00-8753 Cl, alleged, among other causes of action, claims for negligent and intentional infliction of emotional distress. They also stated that Calista and ANI “sexually discriminated” against DeNardo, although the complaints did not explicitly refer to AS 18.80. The discrimination claim relied on the same facts as the negligent and intentional infliction of emotional distress claims. We have held that “the pleadings of pro se litigants should be held to less stringent standards than those of lawyers.”11 This proposition reflects a policy against finding unintended waiver of claims in technically defective pleadings filed by pro se litigants.12 We therefore conclude that DeNar-do’s complaints in Case No. 3AN-00-8753 Cl encompassed a statutory state-law based sex discrimination claim even though they did not refer specifically to AS 18.80.13 Alaska Statute 18.80.220(a) makes it unlawful for an employer to discriminate unjustifiably against a person because of the person’s sex.14
*331The dissent argues at 336-37 that DeNar-do’s position on appeal, which disavows any intent to assert a claim under AS 18.80 in his original state complaint, precludes us from reading that complaint as encompassing such a claim. The dissent’s discussion of DeNar-do’s complaint and the stipulation might be compelling if DeNardo had been represented by counsel. But given the leniency with which we interpret the pleadings of pro se litigants, we think that focusing on DeNar-do’s current understanding of his original pleadings is misplaced. A pro se litigant’s interpretation of his own complaint need not be determinative of what it actually pleads; the court must exercise its independent judgment in determining what claims the complaint’s words assert. DeNardo’s recitation of facts and use of the term “sexually discriminated” in his first complaint establish that it pleaded a AS 18.80 claim, his post hoc explanation of his pleading intentions notwithstanding.15
Although DeNardo’s present interpretation of his first complaint is not determinative of what claims that complaint alleged, his contemporaneous understanding of the meaning of the stipulation for dismissal is relevant to its interpretation. As to this issue, DeNardo contends on appeal that he understood the stipulation to preserve his claims then pending in federal court.
DeNardo’s federal complaint in Case No. A00-309-CV asserted state-law based claims of negligent and intentional infliction of emotional distress as well as federal-law based claims of discrimination. The federal complaint alleged the same facts pleaded in the state law discrimination claim in Case No. 3AN-00-8753 Cl; the complaint in Case No. A00-309-CV therefore should be read to include the same claims as the complaint in Case No. 3AN-00-8753 Cl. For that reason, and given oür leniency in interpreting the pleadings of pro se litigants,16 we read the federal complaint in Case No. A00-309-CV to have asserted: (1) a federally based discrimination claim, (2) a state-law based discrimination claim, and (3) state-law based negligent and intentional infliction of emotional distress claims.
The claims asserted in that federal action are important, given the terms of the stipulation for dismissal signed by the parties in Case No. 3AN-00-8753 CI. To determine the res judicata effect of the stipulated dismissal, it is necessary to determine the stipulation’s effect.
After the first state action was removed to federal court and then remanded to the superior court, the parties signed the stipulation dismissing Case No. 3AN-00-8753 Cl with prejudice.17
Res judicata applies if: “(1) a court of competent jurisdiction, (2) has rendered final judgment on the merits, and (3) the same cause of action and same parties or *332their privies were involved in both suits.”18 In Plumber v. University of Alaska Anchorage we discussed whether a stipulation for dismissal with prejudice could give rise to res judicata:
[A] stipulation to dismiss claims with prejudice is sufficient for res judicata purposes: “[A] stipulation [to dismiss claims with prejudice] is just as valid as a final judgment resulting from a trial on the merits, and is res judicata as to all issues that were raised or could have been determined under the pleadings.”[19]
There is no dispute that the first and third requirements for res judicata are present here. The parties do not dispute the superi- or court’s jurisdiction in the first state action. It is also undisputed that the parties in both the first state action and the present action included DeNardo, Calista, and ANI, and that causes of action are the same in both lawsuits.
But there is a dispute concerning the second requirement. The parties do not dispute that the superior court rendered a final judgment on the merits when it “granted” the stipulation to dismiss with prejudice in Case No. 3AN-00-8753 Cl, but they disagree about what claims the dismissal actually resolved.20
Res judicata based on a stipulated dismissal does not prevent a plaintiff from bringing a cause of action that was expressly reserved for later adjudication.21 A stipulation may reserve a claim for later litigation, and courts will not construe the stipulation to waive rights “not plainly intended to be relinquished.” 22 We recognize that “courts look with favor on stipulations designed to simplify, shorten or settle litigation, or to save costs and will not give such stipulations a forced construction.”23 Moreover, the “language purporting to reserve a claim must be explicit, so that ‘the parties not only ha[ve] an opportunity to dicker over the language, but [are] thereafter on notice about which claims were reserved and which were not.’ Blanket reservations of rights will not suffice.” 24
We therefore turn to the stipulation to determine which claims DeNardo preserved.
Defendants’ counsel drafted the stipulation in Case No. 3AN-00-8753 CI, and DeNardo and defendants’ attorney signed it on April 27, 2001. The first paragraph stated that “the claims asserted by [DeNardo] in [Case No. 3AN-00-8753 CI] ... against all defendants are dismissed in their entirety, with prejudice.” But the second paragraph stated that “[t]his stipulation does not affect plaintiffs claims against Calista Corporation and Alaska Newspapers, Inc. in ... A00-309 Civ ...., currently pending in the U.S. District Court for the District of Alaska.” Therefore, even though DeNardo agreed in the first paragraph to a dismissal with prejudice of the claims he had asserted in his first state court action, the second paragraph preserved his claims against Calista and ANI then pending in federal court as of April 27, when the parties signed the stipulation. The *333claims then pending in federal court included claims for negligent and intentional infliction of emotional distress and discrimination.
The stipulation is ambiguous, because it did not clearly explain how to resolve claims that were pending, as of April 27, 2001, in both state and federal court, i.e., claims encompassed by both the first and second paragraphs of the stipulation. The dissent correctly notes that a dismissal “with prejudice” usually bars a plaintiff from refiling the same claim in the same court.25 But given the ambiguity introduced by the stipulation’s second paragraph, we cannot conclude that the first paragraph’s dismissal of claims “with prejudice” bars this action before we resolve which claims the stipulation dismisses and which claims it preserves.
We conclude, for three reasons, that the stipulation should not be read to foreclose the claims reserved by the second paragraph. First, we hold pro se litigants to less stringent standards.26 Second, we construe the ambiguous terms of the document contrary to the preparer of the document, Calis-ta’s counsel.27 Third, we interpret waiver language narrowly.28
This reading does not render the stipulation a nullity from its inception; when the parties entered into the stipulation, the federal court had not yet ruled that Calista was not an “employer.” Parties entering into the stipulation could have rationally assumed that the federal court, in resolving the Title YII claim, would also resolve the pendant emotional distress claims. Given the litigation history of the employment dispute, parties could have rationally thought it was desirable to attempt to resolve all remaining claims, including the Title VII claim and the “state law claims,” in a single forum in a single proceeding.
Two circumstances might justify a different outcome. First, the policy of favoring stipulations to simplify or settle litigation favors reading the two paragraphs in a way that avoids conflict. Second, extrinsic evidence might help resolve the apparent ambiguity: DeNardo’s April 20, 2001 offer to enter into a stipulation implies that he was willing to dismiss his entire state court action; it stated that he wished only to “maintain the prosecution of his Title VII action in the federal court.” The-text of his dismissal offer would support a conclusion that he only intended to prevent a stipulated state court dismissal from interfering with the federal court proceeding (perhaps through any res judicata effect the proposed dismissal could have on the federal action). This would support a conclusion that the reservation in the stipulation was not necessarily intended to permit DeNardo to begin a new state court action asserting claims that were “in the federal court” only through exercise of that court’s pendant jurisdiction.
But the stipulation’s reservation was not as limited as DeNardo’s offer. Furthermore, the stipulation explicitly preserved DeNar-do’s claims then pending in federal court,29 *334not the forum where those claims were then pending. That the stipulation described the claims to be preserved as those then pending in the federal court did not preclude their later adjudication in state court. Instead, because the stipulation did not state that the preserved claims would be barred in state court if they were not finally adjudicated in federal court, it did not designate the federal court as the exclusive forum for the preserved claims. Despite the apparent dismissal with prejudice of the disputed claims in state court, their dismissal in state court was without prejudice because they were among the pending federal claims expressly preserved.
The dissent argues at 337 that we err by giving DeNardo relief on “unraised substantive grounds” that differ substantially from the issues that the parties actually briefed. In our view, DeNardo raised the grounds on which our holding rests when he asserted in his opening brief that the second paragraph of the stipulation preserved all claims then pending in federal court.
Because DeNardo’s first state court complaint and his federal complaint both included AS 18.80 claims and the stipulation preserved all claims in DeNardo’s federal complaint, we conclude that the stipulation does not prevent DeNardo from litigating his AS 18.80 claim in state court.
3. The federal court’s dismissal
We now turn to Judge Holland’s dismissal order to determine what claims remained after he dismissed DeNardo’s federal case. At least in theory, the federal dismissal order could have res judicata effect. But the federal dismissal order declined to rule on the merits of DeNardo’s non-federal claims. The federal court’s November 2001 order dismissing Case No. A00-309-CV recognized that “[h]aving dismissed plaintiffs Title VII claims, the only claims remaining are plaintiffs pendent state law claims for infliction of •emotional distress.” The federal court stated that “original jurisdiction does not exist for plaintiffs Title VII claim. Accordingly, the court declines to exercise supplemental jurisdiction over plaintiffs state law claim for the infliction of emotional distress.” It concluded that the dismissal “is without prejudice to pursuit of any state law claims plaintiff may have in state court.” Because, as we concluded above, Case No. A00-309-CV included claims of both negligent and intentional infliction of emotional distress and discrimination, and all of these claims were independently based on state law, the dismissal of DeNardo’s Title VII claim did not affect these claims.
The parties compare and contrast claims under Title VII and AS 18.80. Because the federal court dismissed DeNardo’s Title VII claim on jurisdictional grounds based on Cal-ista’s exemption from Title VII claims, dismissal of his Title VII claim does not preclude his AS 18.80 claim.30
DeNardo’s complaint in the present lawsuit explicitly refers to the state anti-discrimination statute, AS 18.80. It also seeks damages for “emotional anxiety and distress” and “for the outrageous and bad faith conduct by defendants done with a reckless disregard and deliberate indifference to [DeNardo’s] civil rights.” Once again, because of our greater leniency toward pleadings of pro se litigants,31 and because all of the claims are based on the same facts, we conclude that DeNardo’s complaint in the present case alleges both discrimination and negligent and intentional infliction of emotional distress. As described above, neither the stipulation nor the federal court dismissal precluded these claims. We therefore conclude that it was error to hold that res judicata prevented DeNardo from pursuing the current action.32
*3354. Claim splitting
The doctrine against claim splitting prohibits “advancing one part of the claim in an initial suit and reserving the remaining parts for a later suit.”33 Because the present lawsuit raises only claims' already raised in the first state action, DeNardo did not split his claim. It was therefore error to hold that the doctrine against claim splitting barred DeNardo’s current action.
5. Rescission of stipulation
DeNardo asserts that stipulations “can be rescinded in the interests of justice and to avoid a manifest injustice.” The superior court denied DeNardo’s motion to rescind the stipulation. DeNardo’s brief does not assert that it was error to deny rescission and its terse reference to the issue is completely insufficient to demonstrate that it was an abuse of discretion to deny the request.34
IV. CONCLUSION
For the foregoing reasons, we VACATE the order dismissing plaintiffs complaint in this lawsuit and REMAND for proceedings consistent with this opinion.

. That DeNardo has not asserted a contemporaneous understanding that the stipulation specifically preserved his AS 18.80 claim does not preclude an interpretation of the stipulation as preserving that claim. DeNardo claims he understood the stipulation more generally as preserving all claims then pending in federal court.
Because DeNardo, as a pro se litigant, is entitled to a lenient interpretation of his federal complaint, his understanding of the stipulation *334as preserving all the claims therein encompasses his AS 18.80 claim.
. See Tru-Line, 52 P.3d at 155.
. See supra note 12.
. DeNardo argues in passing that the Alaska Constitution entitles him to a jury determination of the meaning of his stipulation with Calista. Article I, section 16 of the Alaska Constitution provides that ''[i]n civil cases where the amount in controversy exceeds two hundred fifty dollars, the right of trial by a jury of twelve is preserved to the same extent as it existed at common law.” But disputes over contract interpretation present questions of law. See Peterson v. Ek, 93 P.3d 458, 463 (Alaska 2004). As such, they are not submitted to a jury, which decides questions of *335fact. The stipulation is a contract. DeNardo's argument is therefore without merit. Furthermore, our interpretation of the stipulation renders this argument irrelevant to future litigation in this case.
