In Clifton v. Clifton1 the court held that 12 O.S.Supp.1987 § 1289(F)2 should be construed as a bar to post-decree property division readjustment sought to be rested on an after-enacted spousal right to reach military retirement pension income. Clifton teaches that the provision in subsection (F), which authorizes the reopening of divorce decrees, addresses itself solely to support alimony modification. The narrow issue Clifton left unsettled, which is presented for decision today, is whether decrees rendered before the 1987 amendment enacted by 12 O.S.Supp.1987 § 1289(F) may be reopened for adjudication of the non-military spouse’s previously un-tendered and unresolved support alimony claims sought to be founded on the other spouse’s military retirement income that was not legally reachable at the time of marriage dissolution.
We hold today that after-enacted legislation cannot create post-decree claims for additional spousal alimony support without running afoul of our long-settled decisional law and violating vested rights protected by the Oklahoma Constitution.
I
THE ANATOMY OF LITIGATION
The appellee, James D. Messenger [husband], and appellant, Earla Kay Messenger [wife], were married on July 19, 1963. They were divorced by an Oklahoma decree of December 16, 1981, which provides for the division of all their spousal assets.3 The husband was ordered to pay (a) child support for the parties’ two minor children and (b) support alimony in the amount of $300.00 a month for ten years, or a total of $36,000.00. When the divorce was granted the husband had spent 16 years in active military service. His military retirement rights were not mentioned in. the decree’s property division award.
After the divorce, the husband retired from the service and began drawing his military pension. On March 17, 1988 the wife sought to reopen the divorce decree in an effort to secure additional support alimony and a distributive share of the husband’s military retirement benefits. She contended below that post-decree decisional law came to authorize the inclusion of military pensions among divisible spousal assets.4 She argued that when Congress passed the Uniformed Services Former Spouses’ Protection Act [USFSPA or Act]5 *868in 1983 it sanctioned retroactive modification of a divorce decree to permit an equitable distribution of military retirement pension rights. Finally, the wife urged that the provisions of 12 O.S.Supp.1987 § 1289(F)6 were expressly accorded retroactive effect in a legislative effort to follow the dictates of USFSPA. This was done, her argument went on, because it was Congress’ intention to facilitate state-court post-decree proceedings for reopening those pre-USFSPA decrees which denied the non-military spouse a distributive share of the military retirement pension under the then extant McCarty federal jurisprudential bar.7
The trial court agreed that 12 O.S.Supp. 1987 § 1289(F) was intended to have retrospective effect, but denied the wife’s quest to modify the decree’s property division and support alimony provisions. This ruling the nisi prius court bottomed on the principle that the husband’s military pension had not vested at the date of the marital bond’s dissolution and hence the asset did not qualify as jointly acquired property subject to distribution. In short, the trial court reasoned that since the pension was not part of the marital estate when the divorce was granted, it could not be included as a spousal asset for equitable distribution in a post-decree proceeding.
The Court of Appeals, which reversed this ruling, held the husband’s military pension, though not vested at the time of divorce, was nonetheless a divisible spousal asset.8 Its opinion crafts a new rule that would allow the reopening of pre-amendment decrees for distribution of military retirement rights9 and remands the cause for further proceedings consistent with its own pronouncement.
If the Court of Appeals’ opinion in this case were indeed to become final and the cause to return to nisi prius, the post-decree property redistribution sanctioned by the appellate court clearly would offend our Clifton bar. Because the wife also might assert on remand a support alimony claim grounded on the husband’s income from his military pension, she could avoid offending the teachings of Clifton by amending her claim below to opt instead for support alimony and relinquishing the *869other avenue of relief.10 We granted cer-tiorari on the husband’s petition to decide if on remand the wife could ground her amended claim to an additional support alimony award on the husband’s previously unreachable pension benefits.
II
THE WIFE’S QUEST TO REOPEN THE DIVORCE DECREE FOR REDISTRIBUTION OF SPOUSAL ASSETS AND FOR ADDITIONAL SUPPORT ALIMONY
A. The Property Division Claim— The Clifton Bar
In Clifton the court held that 12 O.S.Supp.1987 § 1289(F) could not serve as a vehicle for reopening a divorce decree to divide military retirement benefits as spousal property, where by law those benefits were not divisible at the time of dissolution.11 The court observed that if it were to conclude § 1289(F) controlled modification of property division awards, an irreconcilable conflict would arise between that section and subsection (A).12 The latter proscribes modification of property division arrangements.
In short, Clifton holds that § 1289(F)’s retroactivity provisions apply only to support alimony awards.13 Its rationale is bottomed on language in subsection (F)14 which refers the reader to subsection (E).15 Subsection (E) authorizes retroactive modification of support obligations upon proof of changed circumstances that affect either the need for or the ability to provide support.16 Property division awards, the court concluded, must stand inviolate except when the decree is subject to vacation in a manner authorized by statute.17
B. The Support Alimony Claim
The wife now predicates her support alimony claim on our construction in Clifton. She seeks to enlarge her previous award by tendering for consideration the husband’s military retirement pension rights, which had not been and could not be previously included for evaluation of her support alimony claim.
*870III
A SUPPORT ALIMONY AWARD IS SUBJECT TO READJUDICATION ONLY IF THE AWARD IS VOID ON THE FACE OF THE JUDGMENT ROLL
At the time the divorce decree was rendered in 1981, the terms of the governing statute—12 O.S.1981 § 1289(B)18—mandated that an alimony judgment be certain as to the total amount of the imposed obligation. A post-decree attack on a monetary alimony award19 by a party who failed to bring a direct appeal for review of that award could succeed only if the award was fatally flawed on the face of the judgment roll.20 A monetary allowance is deemed facially void21 if the total amount of the adjudged obligation is not established in a sum certain or is not in a sum capable of being made certain by reference to the terms of the decree.22 When an alimony award would be found void for indefiniteness of the decreed obligation, the obligor’s liability was subject to readjudication,23
The Messenger decree sets a specific amount of support alimony to the wife, provides the amount due each month, and declares the length of time for the required payments. No appeal was brought from the award following the marital bond’s dissolution. So far as we can ascertain, the face of the judgment roll utterly fails to reveal any jurisdictional defect in the alimony adjudication now sought to be reopened. The judgment was valid when rendered and its efficacy cannot be impaired by after-enacted legislation.24
*871IV
THE DECREED SUPPORT ALIMONY OBLIGATION EMBODIES VESTED RIGHTS THAT ARE CONSTITUTIONALLY PROTECTED BY ART. 5 § 54, OKL.CONST.,25 FROM THE EFFECT OF AFTER-ENACTED LEGISLATION
States establish vested rights by their constitution, statutes or the common law.26 Rights so created become absolute and, by Art. 5 § 54, Okl. Const.,27 are constitutionally shielded from legislative invasion.28
Property interests represented by a divorce decree’s support alimony award are vested rights embodied in a judgment. They are constitutionally insulated by § 54 from legislative interference by after-enacted statutes.29 A decree’s alimony decision constitutes a final judicial assessment of all those assets that are then legally available, and hence properly includable, for consideration in making the spousal support award. The judicial decree that creates a monetary obligation in an inter-spousal suit is a judgment which, when final, stands on a constitutional footing absolutely equal to any money judgment at law.30 It is a final determination of all the rights that necessarily accrue and absolutely vest in the parties.31 After a marriage’s dissolution, all interspousal rights are governed solely by the divorce decree unless there is a valid post-divorce agreement.32
Judgments comprise obligations of the highest nature known to law.33 A judgment’s effect and validity must be governed by the law in force at the time of its rendition. The legislature is constitutionally powerless to burden a judgment with *872conditions not present in the law at the time of its rendition.34
The statutory regime in place when the parties’ 1981 divorce was rendered authorized neither modification of support alimony upon changed conditions35 nor reopening of settled decrees for readjudication of spousal support to be rested upon an after-created claim to a military spouse’s retirement benefits.36 If subsection (F) were to be given retrospective effect, the husband would be stripped of a fundamental law’s protection afforded him by Art. 5 § 54, Okl.Const.
V
THE DECREE’S ADJUDICATION OF SPOUSAL SUPPORT IS ALSO PROTECTED BY ART. 2 § 7, OKL. CONST.37 FROM AFTER-ENACTED LEGISLATION
The rights that come to be vested in every final judgment constitute private property within the meaning of Art. 2 § 7, Okl.Const.38 Section 7 bars the government’s deprivation of property without due process of law. One of the highest functions due process performs is its protection of fundamental rights from substantially unfair or mistaken deprivations by the government, particularly so when the power is exercised for the benefit of private parties.39 Although the state and federal due process clauses40 are similarly, or identically, worded and have a coextensive definitional range,41 we are free, as a matter of state law, to afford protection to state-created rights that is more extensive than that which flows from the federal constitution.42
*873The terms of 12 O.S.Supp.1987 § 1289(F), which appear to sanction modification of a decree-conferred alimony award rendered before that subsections’s effective date, would operate to extinguish vested property rights protected by our fundamental law.43 While the legislature no doubt intended to adjust a perceived past inequity inflicted on non-military spouses, all statutes—especially those that operate retroactively upon vested rights—must conform to the minimum standards of the state constitution and to the values it protects.44 Our fundamental law’s due process clause was explicitly designed to shield citizens from the efforts of well-intentioned lawmakers no less than from those suspected of less supportable motives.45 The legislature stands powerless to abrogate rights whose existence cannot be questioned.46
VI
THE NARROW EXCEPTION CARVED OUT IN NANTZ v. NANTZ47 IS INAPPLICABLE HERE
The constitutionally shielded concept of an “accrued” or “vested right” in an adjudicated obligation48 was neither eroded nor intended to be abolished in Nantz. There, the court held the legislature can establish a condition for terminating support alimony payments and make that after-enacted condition apply to unac-crued portions of awards that mature after the new law has become effective.49 The court anchored its conclusion in the modifiable and terminable nature of support alimony. Nantz, which carved out but a narrow exception to the general rule that after-enacted statutes do not affect the terms or validity of a judgment, rests on the rationale that a decreed support obligation payable in installments represents a series of judgments, each one of which is governed by the law in force at the time the installment falls due.50
In sum, Nantz protects the “accrued right” to a support alimony installment only after it falls due.51 Its teaching does not apply here.
SUMMARY
Art. 5 § 54, Okl.Const., makes support alimony awards impervious and invulnerable to tinkering by after-enacted legislation. Finality of decreed spousal support stands protected by the due process guar*874antees of Art. 2 § 7, Okl.Const. The § 1289(F) ground for modification, enacted after the rendition of the decree here in contest, is not legally available to increase the amount of the military husband’s previously decreed support alimony. The Nantz exception—inapplicable here—is hence unavailable for invocation.
On certiorari previously granted, the opinion of the Court of Appeals is accordingly vacated and the trial court’s post-decree order is affirmed.52

. From the scanty record before us we cannot resolve the parties’ dispute over whether the decree was based (a) on an agreed settlement approved by the court or (b) on the wife’s waiver of appearance and of right to plead, as well as on her consent to reaching the merits of the case without further notice to her. We hence express no opinion on this issue. See in this connection Dickason v. Dickason, Okl., 607 P.2d 674, 677 (1980).

Congress enacted USFSPA in response to McCarty v. McCarty, 453 U.S. 210, 101 S.Ct. 2728, 69 L.Ed.2d 589 (1981). McCarty held that armed services’ retirement income was to be treated in dissolution proceedings as the military spouse’s separate asset. Prior to McCarty, each state had applied its own law to govern divorce-related interspousal division of military *868retirement benefits. USFSPA's intention was to reinstate the authority to apply the state law in effect before McCarty. On November 5, 1990, Congress made its intentions clear by amending USFSPA to protect pre-McCarty divorce decrees from being reopened. (P.L. 101-510). The amendment provides in pertinent part:
"Sec. 555. AMENDMENTS TO THE UNIFORMED SERVICES FORMER SPOUSES’ PROTECTION ACT
(A) PROHIBITION OF CERTAIN RETROACTIVE COURT ORDERS.—Subsection (c)(1) of section 1408 of title 10, United States Code, is amended by adding at the end of the following new sentence: 'A court may not treat retired pay as property in any proceeding to divide or partition any amount of retired pay of a member as the property of the member and the member’s spouse or former spouse if a final decree of divorce, dissolution, annulment, or legal separation (including a court ordered, ratified, or approved property settlement incident to such decree) affecting the member and the member’s spouse or former spouse (A) was issued before June 25, 1981, and (B) did not treat (or reserve jurisdiction to treat) any amount of retired pay of the member as property of the member and the member’s spouse or former spouse.'" (Emphasis added.)

. The Court of Appeals relied upon Carpenter v. Carpenter, Okl., 657 P.2d 646, 651 (1983), where the court held that absent special considerations, retirement benefits earned during the marriage constitute marital property.
. The Court of Appeals held that the trial court is authorized to modify post-June 26, 1981 decrees to distribute military retirement income to the extent the spouse’s asset was acquired or enhanced during the marriage under the following conditions: [1] the parties were married for the requisite period of ten years as required by 10 U.S.C. § 1408(d)(2); [2] the military retirement asset was not previously considered when the divorce was granted either (a) as an item of jointly acquired property subject to division or (b) as income for the purpose of support alimony; [3] only "disposable retired or retainer pay" under 10 U.S.C. § 1408 is allowed to be distributed; and [4] the payments to the former spouse of the military pension benefits will terminate upon the retiree’s death.
. In Seymour v. Swart, Okl., 695 P.2d 509, 512-513 (1985), we noted that when, on a judgment’s reversal a cause is remanded for a new trial, it returns to the trial court as if it had never been decided, save only for the "settled law” applicable to the case.

. U.S. Supreme Court jurisprudence need not be dispositive of questions involving rights guaranteed by state constitutional provisions. States are free to interpret their own due process clauses to afford protection beyond that granted by the federal constitution, even when the state and federal constitutions are similarly or identically phrased.

. In Nantz the court held the terms of 12 O.S.Supp.1987 § 1289(G) free from constitutional infirmity. Section 1289(G)—enacted after the Nantz appeal was lodged, provides that the ■ § 1289(D) "voluntary cohabitation” ground for alimony modification may be applied to modify awards rendered before subsection D's effective date.
. In Nantz, supra note 47 at 1140, the court stated that "[s]ince support alimony is terminable and modifiable, then the right is not vested at the time of the decree, but only at the time each payment becomes due.” The court treats only the accrued portions of the decreed obligation as embodying vested rights.
I did not join in Nantz because, in my view, monetary support alimony awards—both as to accrued and unaccrued installments—constitute vested rights that are constitutionally shielded from diminution by after-enacted legislation.
