OPINION
Kenda Carolyn Treadway appeals the entry of two Qualified Domestic Relations Orders (QDROs) issued to enforce the division of George Payton Shanks’s employee retirement benefits awarded in the parties’ 1981 decree of divorce. We conclude the QDROs alter the substantive division оf property made in the divorce decree. Accordingly, we reverse and remand.
Factual and Procedural Background
Treadway and Shanks were married in 1962 and divorced in 1981. After a con *4 tested bench trial, the court entered a decree of divorce that divided the community property and retirement benefits. The divorce became final, and neither party filed an appeal.
Shanks was employed by American Airlines from 1966 until he retired in 1998. His retirement benefits included both a defined benefit plan and a defined contribution plan. In March 1998, several months before his retirement, Shanks filed a motion requesting the court to sign a proposed QDRO to direct the disbursement of his retirement benefits. Tread-way filed her response, requesting the court to sign her proposed QDRO. In May 1998, the court entered two QDROs, one order proposed by Shanks relating only to the defined benefit plan and the other QDRO, Treadway’s proposed order encompassing both retirement plans. Treadway filed a notice of appeal of the QDRO related to the defined benefit plan. Shanks filed a motion for the trial court to vacate and reconsider the other QDRO and a request that the сourt sign a separate QDRO for the defined contribution plan. Treadway’s appeal of the defined benefit plan QDRO was transferred to the Texar-kana Court of Appeals. 2
In June 1998, the court granted Shanks’s motion to reconsider, vacated the QDRO that referred to both retirement plans, entered Shanks’s QDRO for the defined contribution plan, and reconfirmed the QDRO for the defined benefit plan. Treadway filed this appeal complaining of both QDROs. The Texarkana Court of Appeals dismissed Treadway’s prior appeal of the defined benefit plan QDRO, concluding the reconfirmation of that QDRO in June 1998 restarted the appellate timetable and deprived that court of jurisdiction. 3
Jurisdiction
We must first consider Shanks’s cross-issue, alleging this Court has no jurisdiction to consider the appeal of the defined benefit plan QDRO. Shanks argues that his motion to vacate and rеconsider did not relate to the defined benefit plan QDRO and, therefore, the May 1, 1998 defined benefit plan QDRO was a final order. According to Shanks, the June 17, 1998 order reconfirming the defined benefit plan QDRO was entered after the trial court lost plenary jurisdiction to affect that QDRO, and, contrаry to the finding of the Texarkana Court of Appeals, the appellate timetable for that order was not restarted.
Shanks further argues that, because Treadway did not challenge the Tex-arkana Court of Appeals’ dismissal, she should not be allowed to proceed with the appeal of the defined benefit plan QDRO. However, the law of the case doctrine provides that the final ruling of an appellate court on a question of law in a case will govern throughout the subsequent proceedings of the same case.
See Hudson v. Wakefield,
Moreover, Shanks’s motion to reconsider requested Treadway’s QDRO be
*5
vacated. Because Treadway’s QDRO included provisions for both the defined benefit and defined contribution plans, Shanks’s motion to vacate Treadway’s QDRO constituted a motion to modify, correct, or reform the judgment of the court that extended the plenary power of the' court over both QDROs. See Tex.R. Civ. P. 329b(g). By vacating Treadway’s QDRO and re-adopting the defined benefit plan QDRO as the order of the court, the June 1998 order altered and/or clarified Treadway’s rights under the defined benefit plan. Thus, the June 17, 1998 order operated as an order modifying, correcting, or reforming the original judgment, and it automatically restarted the appellate timetable anew from its date. See Tex.R. Civ. P. 329b(h); see

Standard of Review
Because the trial court did not make findings of fact or conclusions of law, we must assume that it made all findings in support of its judgment.
Pharo v. Chambers County, Tex.,
The Divorce Decree
The parties agree that the trial court had no authority to alter the substantive property division contained in their 1981 decree of divorce.
See
Tex. FamlCode Ann. § 9.007 (Vernon 1998);
Milligan v. Niebuhr,
The QDROs in this case grant Treadway twenty-five percent of the retirement benefits that accrued or were attributable to Shanks’s employment before the date of divorce. Treadway contends the divorce decree granted her twenty-five percent of all of Shanks’s retirement benefit, including that which accrued after the parties divorced. The relevant portion of the divorce decree provides:
The Court finds that Respondent has earned certain employee benefits under a pension plan arising out of past employment as an employee of American Airlines.
Petitioner is awarded a “pro-rata interest” (as hereinafter defined) of any and all sums received or paid to Respondent from such pension plan and such sum or sums shall be payаble to Petitioner if, as and when paid by American Airlines or the trustee of such plan to Respondent as pension or retirement employee benefits existing because of Respondent’s employment.
IT IS DECREED that Petitioner’s “pro-rata interest” shall be defined as that sum of money equаl to 25% of the total sum or sums paid or to be paid to *6 Respondent from such pension or retirement plan.
This case involves the interpretation of this provision. The same rules of interpretation apply in ascertaining the meaning of judgments as in ascertaining the meaning of other written instruments.
Lone Star Cement Corp. v. Fair,
If the decree taken as a whole is unambiguous, the trial court is required to declare the effect of the decree in light of the literal meаning of the language used.
Wilde v. Murchie,
In contrast, if the decree is ambiguous, the court must interpret it by reviewing both the decree as a whole and the record to ascertain the property’s disposition.
Wilde,
In her third issue, Treadway contends the language of the decree unambiguously awarded her twenty-five percent of Shanks’s total retirement benefit. She relies on the decree provision that she was awarded a pro-rata interest of “any and all sums received or paid to Respondent ... payable ... if, as and when paid” to Shanks, and that the term “pro-rata interest” is defined as “25% of the total sum or sums paid or to be paid to Respondent.” Although Shanks agrees the decree is unаmbiguous, he contends the QDROs are correct because the divorce decree specifically refers to a “pension plan arising out of past employment.” He argues that Treadway’s interest in “such pension plan” relates only to the pension plan that existed by virtue of the past employment.

Judgments, like other written instruments, are to be construed as a whole toward the end of harmonizing and giving effect to all the court has written.
Constance v. Constance,
Shanks argues that if the language of the judgment is susceptible to more than one interpretation, we should adopt the оne that harmonizes it with the facts and the law of the case.

Second, the law related to the division of retirement benefits went through several changes during the period immediately рreceding this divorce.
See Baxter,
Third, and most importantly, the doctrine of res judicata requires us to uphold the decree even if the divorce decree improperly divided the property and did not comply with the substantive law in effеct when the decree was rendered.

Cook v. Cameron,
Because we conclude that the decree is unambiguous and, as worded, awards Treadway twenty-five percent of Shanks’s total retirement benefit, we sustain Tread-way’s third issue. We therefore further conclude that the QDROs entered by thе court alter the substantive division of property made in the divorce decree. See Tex. Fam.Code Ann. § 9.007 (Vernon 1998). Accordingly, we sustain Treadway’s first issue. Because we conclude the decree is unambiguous, it is unnecessary for us to address Treadway’s second issue. See Tex.R.App. P. 47.1. We reverse the judgments of the trial court and remand for the court to enter revised QDROs that conform with this opinion.

. Shanks's argument might apply if the QDROs were for a new or different pension plan. The literal language of the decree refers to the pension plan that existed at the time of divorce, but not the pension plan as it existed at the time of divorce.

and

are distinguishable because the judgments in those cases were agreed judgments and explicitly calculated the community portion of defined benefit retirement plans using the
