OPINION

In this appeal, a wife asserts that the trial court erred in granting summary judgment to her husband on her post-divorce proceeding to divide an employment-related bonus the husband received nine months after their divorce. Because we conclude that the bonus was not considered, divided, or partitioned in the divorce proceedings and the wife raised a fact issue concerning the characterization of this bonus, we reverse and remand for further proceedings.

BACKGROUND

Miguel Angel Loya and Leticia B. Loya married in July 1980. In April 2008, Leticia filed for divorce. During their marriage and afterward, Miguel worked for Vitol, Inc. As an employee of Vitol, Miguel was eligible for, but not entitled to, a discretionary bonus:

You will continue to be considered for an annual bonus based on various performance parameters considered by [Vitol]. Bonuses are completely at the discretion of [Vitol] and, if paid, are typically paid in March/April each year.

During the couple’s marriage, Miguel earned this discretionary bonus regularly. According to Miguel, his bonus paid in 2010 was awarded to him shortly before the divorce and was placed into a bank account that was awarded to Leticia in the parties’ Mediated Settlement Agreement (MSA). Thus, before executing the MSA, Miguel contends that Leticia was aware of the potential that Vitol would pay Miguel a bonus in 2011.

On June 13, 2010, the parties signed the MSA, which also served as “an immediate partition”:

Agreement Supersedes Prior Agreements and Serves as an Immediate Partition. The provisions of this Agreement shall be effective immediately as a contract, shall supersede any temporary orders or other agreements of the parties (except the parties’ partition agreement of September of 2009 and orders or agreements concerning the children & trust, which shall remain in place) with respect to the subject matter hereof, and shall serve, as a partition of all property set forth herein to the person to whom such property is awarded. All future income of a party and/or from any property herein awarded to a party is portioned to the person to whom the property is awarded. All future earnings from each party are partitioned to the person providing the services giving rise to the earnings. These partitions are to be effective pursuant to Section 4.102 of the Texas Family Code, and in *365this respect, each party waives further disclosure of property and debts of the other party. Any spouse holding title to property herein awarded or confirmed to the other spouse shall hold such property as a constructive trustee until such time that tile or other muniment to the property can be transferred to the spouse to whom such property is awarded or confirmed.

(emphasis added). On June 14, Leticia presented the MSA to the trial court and requested that it be entered. The trial court orally announced the parties’ divorce that day on the record. The court also set an entry date and ordered the parties to draft their final documents.

Shortly thereafter, Leticia filed a motion to set aside the MSA. In this motion, she urged that the MSA should be set aside, because there was no mutual assent or meeting of the minds because the parties “did not reach an agreement as to the division of ... the community’s interest in Miguel Angel Loya’s bonus to be paid in 2011, nearly half of which pertains to [Mi-guelj’s services through June 13 2010.”1 Leticia urged that the MSA “did not address or divide the community’s portion of the bonus.” On June 22, 2010, the trial court denied Leticia’s motion and signed the parties’ final decree of divorce, which incorporated an agreement incident to divorce (the AID) setting out the terms of the MSA.2 The AID and the divorce decree both provided that any community assets of the parties not divided by the parties’ agreements would be subject to future division.3 Leticia did not appeal from the final divorce decree.4

On March 15, 2011, Miguel received a bonus from Vitol in the gross amount of $4.5 million; the amount received net of taxes and retirement was slightly over $2.85 million. In June 2012, Leticia filed an original petition for post-divorce division of property, seeking to divide Miguel’s 2011 bonus.5 ■ Miguel moved for partial summary judgment on Leticia’s claim on grounds that: (1) the bonus was not community property subject to division by the *366trial court; (2) if the bonus was subject to division, it was partitioned to Miguel pursuant to the MSA; and (3) Leticia’s, claim was barred by principles of res judicata because the trial court considered the division of the bonus through Leticia’s motion to set aside the MSA. Leticia responded, asserting that genuine issues of material fact exist concerning whether (a) the bonus was community property subject to division, (b) the bonus was awarded to Miguel in the divorce, and (c) Leticia’s suit was barred by res judicata.

The trial court considered the partial summary judgment motion on October 29, 2012. It signed an interlocutory order granting Miguel. partial summary judgT. ment on December 7, 2012, which left open the issue of Miguel’s claim for attorney’s fees and sanctions. The trial .court signed a final take-nothing order on Leticia’s petition for post-divorce division of property on January 6, 2014, after Miguel abandoned his claim for attorney’s fees. Leticia filed a motion for new trial; our record contains no ruling on this motion. This appeal timely followed.

Analysis

Leticia challenges the summary judgment in four issues. In her first two related issues, she asserts that Miguel failed to conclusively prove that the bonus was his separate property; alternatively, she asserts that there is a fact issue concerning the characterization of the bonus. In her third issue, Leticia urges that the bonus was not partitioned in the decree of divorce. Finally, in issue four, she contends that res judicata does not apply because the divorce decree did not award the bonus to anyone. Because we conclude that the bonus was not considered, disposed of, or partitioned in the divorce decree, and that Leticia raised a fact issue concerning the characterization of the bonus, we reverse the summary judgment and remand to the trial court for further proceedings.

A. Standard of Review and Applicable Law

We review summary judgments de novo, and where, as here, the trial court grants the judgment without specifying the grounds, we will áffirm if any of the grounds presented are meritorious. FM Props. Operating Co. v. City of Austin, 22 S.W.3d 868, 872 (Tex. 2000). The movant for a traditional summary judgment must show that there is no genuine issue of material fact and that it is entitled to judgment as a matter of law. Tex. R. Civ. P. 166a(c); Mann Frankfort Stein & Lipp Advisors, Inc. v. Fielding, 289 S.W.3d 844, 848 (Tex. 2009). To be entitled to a traditional summary judgment, a defendant must conclusively negate at least one essential element of each of the plaintiffs causes of action or conclusively establish each element of an affirmative defense. Sci. Spectrum, Inc. v. Martinez, 941 S.W.2d 910, 911 (Tex. 1997). “Evidence is conclusive only if reasonable people could not differ in their conclusions.... ” City of Keller v. Wilson, 168 S.W.3d 802, 816 (Tex. 2005). Once the defendant establishes its right to summary judgment as a matter of law, the burden shifts to the plaintiff to present evidence raising a genuine issue of material fact. Walker v. Hams, 924 S.W.2d 376, 377 (Tex. 1996). We review the summary judgment evidence in the light most favorable to the nonmovant, crediting evidence favorable to the nonmovant if reasonable fact finders could, and disregarding contrary evidence unless reasonable fact finders could not. Mann Frankfort, 289 S.W.3d at 848; see also Joe v. Two Thirty Nine Joint Venture, 145 S.W.3d 150, 156 (Tex. 2004).

Community property consists of the property, other than separate proper*367ty, acquired by either spouse during marriage. Tex. Fam. Code Ann. §"8.002. Property possessed by either spouse during or on dissolution of marriage is presumptively community property. Id. § 3.003(a). Further, “earnings during marriage, even during the pendency of divorce proceedings, are community property.” Marriage of O’Brien, 436 S.W.3d 78, 84 (Tex.App.—Houston [14th Dist.] 2014, no pet.). A spouse’s separate property consists of the property owned or claimed by the spouse before marriage, acquired by the spouse during the marriage by gift, devise, or descent, and the recovery for personal injuries sustained by the spouse during marriage (except for recovery for loss of earning capacity). Tex. Fam. Code Ann. § 3.001. Finally, “[ejither spouse may file a suit ... to divide property not divided or awarded to a spouse in a final decree of divorce.” Id. § 9.201(a). In an action to divide community property post-divorce, the petitioner bears the burden to prove that the trial court did not consider or dispose of the property at issue. See Brown v. Brown, 236 S.W.3d 343, 348-49 (Tex.App.—Houston [1st Dist.] 2007, no pet.).

B. Application

We first consider Leticia’s third and fourth issues, in which she challenges the summary judgment on res judicata and partition grounds, before turning to the question of whether she raised a genuine issue of material fact as to the characterization of Miguel’s bonus. ,

1. The bonus was not considered,' divided, or partitioned in the divorce decree or other agreements of the parties.

“Res judicata precludes re-litigation of claims that have been finally adjudicated or that arise out of the same subject matter and could have been raised and litigated in the prior action.” Appleton v. Appleton, 76 S.W.3d 78, 83 (Tex.App.—Houston-[14th Dist.] 2002, no pet.). But community-property not awarded or partitioned by a divorce decree is subject to later partition between the ex-spouses. See Tex. Fam. Code Ann. § 9.201(a); Appleton, 76 S.W.3d at 83 (citing Harrell v. Harrell, 692 S.W.2d 876 (Tex. 1985); Busby v. Busby, 457 S.W.2d 551, 554 (Tex. 1970)). Res judicata does not apply to post-divorce partitions where the divorce decree has not disposed of an asset; partition is appropriate in such a situation. Appleton, 76 S.W.3d at 83 (citing Busby, 457 S.W.2d at 554).

The MSA, the divorce decree, and the AID do' not mention the 2011 bonus. Leticia filed a motion to set aside the MSA based in part on the failure of the parties to divide the bonus. Miguel asserts that the trial court thus “considered” the bonus, and res judicata prevents Leticia from re-litigating the division of this property. Importantly, however, Leticia did not seek to divide this property in her motion; instead, she asserted that the MSA should be set aside because of a lack of mutual assent. Indeed, as noted above, Leticia averred that the MSA “did not address' or divide the community portion” of the bonus. Because nothing in our record indicates that the trial court considered or disposed of the bonus, Leticia is not barred by res judicata principles from bringing this suit. See Tex. Fam. Code Ann. § 9.201(a); Appleton, 76 S.W.3d at 83!

Further, the MSA — the only valid partition agreement in this case — provides as follows: ' '

Income Tax Returns for the Year 2010. For 2010, each party shall file an individual income tax return in accordance with Internal Revenue Code section[] 66(a) as if they were divorced on 12:01 a.m. oii January 1, 2010. This [MSA] *368shall serve as a partition of community income, setting aside to each spouse all income earned by each such spouse and/or attributable to property awarded to each such spouse or confirmed as each such spouse’s separate property herein. For the entire year 2010, each spouse shall be solely entitled to take on his/her return any deductions attributable to properties awarded herein to him/her or confirmed as his/her separate property. All overpayments from 2009, all estimated taxes paid relative to the parties’ tax liability for 2010, all with- ' holding relative to the parties’ tax liability for 2010, plus any other tax deposits made otherwise credited relative to the parties’ tax liability for 2010 are allocated solely to Miguel....

Miguel asserts that this language from the MSA partitions his 2010 income to him.6 We must disagree. First, this provision of the MSA is related to filing of income tax returns: it states that the parties must file individual income tax returns “as if they were divorced” on January 1. It does not expressly partition the parties’ income earned in 2010 to that party. And the MSA previously expressly partitioned only all “future earnings” to the “person providing the services giving rise to the earnings.” This partition of future earnings has no impact on the characterization of earnings prior to the execution of the MSA; instead, these earnings are properly characterized as community property. See O’Brien, 436 S.W.3d at 84.

For the foregoing reasons, we conclude that Miguel’s 2011 bonus was not considered, divided, or partitioned in the MSA, the AID, or the divorce decree. Thus, summary judgment was not proper on these grounds, and we sustain her third and fourth issues.

2. Leticia raised a fact issue as to the characterization of the bonus.

In Sprague v. Sprague, this court considered whether bonuses awarded during a marriage for work performed at least partially before the marriage could be established as a spouse’s separate property. 363 S.W.3d 788, 801-02 (Tex.App.—Houston [14th Dist.] 2012, pet. denied). Evidence of the characterization of these bonuses was improperly excluded from the fact finder. See id. We determined that that the exclusion of this evidence probably caused the rendition of an improper judgment because the spouse was entitled to present evidence that portions of these bonuses were awarded based on work performed before the marriage; i.e., this spouse should have been permitted to present evidence that portions of these bonuses were separate property. See id. In other words, there is no bright line rule for bonuses: a bonus paid during marriage may be based in part on work performed prior to the marriage, which would make that portion of the bonus a spouse’s separate property. It follows from our analysis in Sprague that a bonus paid post-divorce, but alleged to be based in part on work performed during the marriage, *369could.be subject to proof that some portion of this bonus is community property.

Here, through his summary judgment evidence, Miguel established that the 2011 bonus was paid to him in March 2011, nine months after he and Leticia were divorced. In response to this evidence, Leticia provided an affidavit in which she stated that the MSA “did not address or divide the community portion of Miguel’s bonus for services performed between January 1, 2010 and June IS, 2010, to be paid in 2011 ” (emphasis added).7 She further stated that she- did not intend that “all income that Miguel earned from January 1, 2010 through June 13, 2010, including his bonus, would be considered his separate property and not subject to division.” Viewing this evidence in the light most favorable to Leticia,8 we conclude that Leticia brought forth some evidence that Miguel’s bonus, although paid in 2011, was based in part on work he performed before the parties divorced. Cf. Sprague, 363 S.W.3d at 801-02. And Miguel did not establish that the 2011 bonus was not earned, at least in part, based on services he provided during the parties’ marriage. See, e.g., Bell v. Moores, 832 S.W.2d 749, 752 (Tex.App.—Houston [14th Dist.] 1992, writ, denied) (“Personal earnings are community property if earned during the mhr-riage.”); see also Tex. Fam. Code Ann. § 7.003 (“In a decree of divorce or annulment, the court shall determine the rights of both spouses in a pension, retirement plan, annuity,' individual retirement account, employee stock option plan, stock option, or other form of savings, bonus, profit-sharing, or other employer plan or financial plan of an employee or a participant, regardless of whether the person is self-employed, in the nature of compensation or savings.” (emphasis added)). Under these circumstances, we conclude that Leticia raised a genuine issue of fact concerning whether some portion of Miguel’s bonus could be based on services he provided while the ex-spouses were still married; i.e., whether some portion of the bonus is community property.

Our dissenting colleague appears to urge.that “future earnings” are measured solely by the ex-spouse’s receipt. of the “earnings.” This construction ignores the plain language of the MSA, which, as excerpted above, partitions future earnings to the “person providing the services giving rise to the earnings.”. Thus, if Miguel’s services during the marriage gave rise, in part, to the 2011 bonus, then some portion of the 2011 bonus could be characterized as community property. We express no opinion as to whether any portion of the 2011 bonus was based on services Miguel provided during his marriage to Leticia. Instead, we conclude that Miguel *370has'not established as a matter of law that his 201Í bonus was based eritirely on services he provided after the parties’ divorce.

For the foregoing reasons, on this record, summary judgment was not proper on the characterization of Miguel’s bonus, and we sustain Leticia’s second issue.9

Conclusion

Having sustained Leticia’s second, third, and fourth issues, we reverse the trial court’s judgment and remand for further proceedings.

Frost, C.J., dissenting

dissenting.

Miguel and Leticia signed a mediated settlement agreement (MSA) regarding their" divorce, and based on this agreement, the. trial court rendered a divorce decree. Under their agreement, Miguel’s future earnings and income were partitioned to Miguel. Nine months after the trial court rendered the divorce decree, Miguel received a bonus from his employer.' Leticia petitioned for post-divorce division of community property, seeking division of the bonus, which Leticia contends is community property not divided in the divorce decree. She took the position that despite the terms of the agreement, the parties had not partitioned, divided, or allocated the bonus to either party.

Miguel filed a summary-judgment motion asserting Leticia’s claim fails as a matter of law because, among other things, to the extent the bonus or any part of it was community property, it was partitioned to Miguel under the parties’ agreement. The majority concludes that' the bonus was not partitioned in the agreement because the bonus constitutes “earnings prior to the execution of the MSA.” But, under the unambiguous language of the agreement, Miguel’s bonus is encompassed by the provision partitioning future earnings and income to Miguel. For this reason, the agreement partitioned the bonus to Miguel. It belongs to him. The trial court properly granted summary judgment.

The Agreement’s “Future Earnings and Income” Provision

The agreement contains a detailed list of the parties’ marital property and divides that property between them. The list does not specifically refer to future bonuses, but the parties considered and partitioned “future earnings and income.” Their agreement includes the following provision:

All future income of a party and/or from any1 property herein awarded to a party is partitioned to the person to whom the property is awarded. All future earnings from each party are partitioned to the person providing the services giving rise to the earnings. These partitions are to be effective pursuant to Section 4.102 of the Texas Family Code, and in this respect, each party waives further disclosure of property and debts of the other party.1

The agreement requires the parties to submit “(a) draft disputes, (b) issues regarding the interpretation of this Mediated Settlement Agreement, and (c) issues regarding the intent of the parties” to binding arbitration.2 While drafting their pro*371posed agreed divorce decree, the parties disagreed about the language of the “future earnings” provision and arbitrated their drafting dispute. The arbitrator instructed the parties to include following language:

All future income and earnings are partitioned as of June 13, 2010[,] however[,] for tax purposes the partition of income for 2010, is as of Jan. 1, 2010_ If there is undisclosed property that occurred in this period of January 1, 2010 through June 13, 2010, that will have to be dealt with whether as undisclosed property or otherwise.

Leticia, asserts, that the agreement’s “future earnings” provision does not address Miguel’s March 2011 bonus, and that the. arbitrator’s determination ■ confirms as much. Miguel asserts that the “future earnings” provision encompasses the March 2011 bonus and the arbitrator’s determination confirms the bonus was partitioned to him.

Interpretation of the Provision

A mediated settlement agreement that meets . certain statutory formalities is binding on the parties and requires the rendition of a divorce .decree that adopts the parties’ agreement.3 Settlement agreements are subject to the rules of contract construction.4 In construing contracts, the court’s primary concern is to ascertain and give effect to the intentions of the parties as expressed in the contract.5 To ascertain the parties’ true intentions, the court examines the entire agreement in an effort to harmonize and give effect to all provisions so that none will be rendered meaningless.6 Whether a contract is ambiguous is a question of law for the court.7 A contract is ’ambiguous if its meaning is uncertain ’ and doubtful or is reasonably susceptible to more than one interpretation.8 But, when a.-.written contract is worded so that it can be given a certain or definite legal meaning- or interpretation, it is unambiguous, and the court construes it as a matter of law.9 The court cannot *372rewrite the contract or add to its language under the guise of interpretation.10 Rather, the court must enforce the contract as written.11.

The agreement partitions “future income and earnings” to Miguel. The agreement does not define the phrase or either of its components. To determine whether the partition includes the March 2011 bonus, we must look to the plain meaning of the language.12 According to Black’s Law Dictionary, “income” is “the return in money from one’s business, labor, or capital invested; gains, profits, salary, wages, etc.”13 “Income” is also defined as “the true increase in amount of wealth which comes to a person during a stated period of time.”14 Section 101.011 of the Texas Family Code defines “earnings” broadly as “a payment to or due to an individual, regardless of source and how denominated.” 15 Section 101.011 notes that the term includes “wages, salary, compensation received as an independent contractor, overtime pay, severance pay, commission, bonus, and interest income.”16 Similarly, Black’s Law Dictionary defines “earnings” as “income” and the dictionary notes that it is not limited to wages.17 The plain meanings of the terms “income” and “earnings” encompass Miguel’s March 2011 bonus.

In negotiating the community property split in June 2010, the parties allocated to Miguel all future earnings and income. Miguel received the March 2011 bonus after the execution of the MSA. Thus, under the clear terms of the agreement, the March 2011 bonus is allocated to Miguel under the “future earnings” provision.

The majority applies Sprague v. Sprague and determines that a portion of the bonus is community property subject to division.18 Even if a portion of the bonus could be characterized as community property, Leticia and Miguel partitioned this community property to Miguel in their agreement when they allocated all future earnings and income to Miguel. The majority states that the March 2011 bonus was based “in part on work [Miguel] performed before the parties divorced.”19 The majority then concludes that the bonus was “earned, at least in part, based on services [Miguel] provided during the parties’ marriage.”20 Thus, the majority reasons that a portion of the March 2011 bonus was past “earnings” or “income” not covered by the parties’ partition agreement.21

*373In interpreting the agreement, the court is to give effect to the plain meaning of the words.22 “Future” is defined as “that is still to be,” and “existing or occurring at a. later time.”23 The parties divorced in June 2010. Miguel’s employer awarded the bonus in March 2011. At the time the parties divorced, the bonus did not exist. Even if Miguel’s employer considered work Miguel performed before June 2010 in awarding the March 2011 bonus, none of the bonus came into existence until after June 2010. Therefore,, under the wording of the agreement, the entire bonus fell within the provision relating to future earnings or income and was partitioned to Miguel.

Conclusion

In their agreement, the parties partitioned all of the March 2011 bonus to Miguel. Miguel sought summary judgment on the ground that he was entitled to the entire bonus because the parties partitioned it all to him. The trial court did not err in granting Miguel’s summary-judgment motion. Because the majority reaches the opposite conclusion, I respectfully dissent.
