Thomas C. Maddux appeals a civil contempt holding wherein the district court for Red Willow County found him in contempt of court for failure to pay child support as ordered.
In its order of February 16, 1989, the trial court found that *241 Maddux “has remained in continued contempt of this Court, that unless he pays the amounts due he is sentenced to thirty (30) days in jail commencing April 1,1989.”
We find that the trial court committed plain error when it imposed a punitive sanction rather than a coercive sanction as required in a civil contempt proceeding. We therefore vacate the trial court’s punitive sanction and remand the contempt proceeding with direction to the trial court to impose a coercive sanction.
Maddux’s ex-wife, Tanya, has cross-appealed the trial court’s retroactive reduction in child support Maddux was ordered to pay. We also reverse the trial court on this issue.
THE CONTEMPT PROCEEDINGS
The Supreme Court always reserves the right to correct error unassigned or uncomplained of but which is plainly evident from the record and prejudicially affects a litigant’s substantial right, and which if left uncorrected would result in a miscarriage of justice or damage the integrity, reputation, and fairness of the judicial process, regardless of whether the error was raised at trial or on appeal.
State
v.
Nowicki, ante
p. 130,
The contempt proceeding in this case was instituted by Maddux’s ex-wife and was tried as civil, not criminal, contempt. See
State ex rel. Collins
v.
Beister,
Citing
Liles,
this court has dismissed, for lack of an appealable order, appeals based upon lower court findings of contempt for failure to pay child support in civil proceedings. Since the contemner in child support cases is given an opportunity to purge himself or herself of the contempt by paying what the court finds to be a reasonable amount under the circumstances toward the child support arrearages, the contemner “holds the keys to his jail cell” because the sentence is conditioned upon the contemner’s continued noncompliance. See,
Rol
v.
Rol,
The issues here are whether Maddux did indeed “hold the keys to his jail cell” and whether the trial court’s order fixed a reasonable sum of money under the circumstances for Maddux to pay toward his child support arrearage to purge himself of contempt. The order of the district court in this case provided that “unless [Maddux] pays the amounts due he is sentenced to thirty (30) days in jail commencing April 1,1989.” A criminal or punitive sanction is invalid if imposed in a proceeding that is instituted and tried as a civil contempt. See
In re Contempt of Sileven,
A punitive contempt sanction imposed by a trial court in a child support case must be set aside when the commitment to jail is to take effect in futuro, because such a commitment is a
*243
conditional judgment. See,
Romshek
v.
Osantowski,
When a commitment to jail is utilized as a coercive sanction in a civil contempt proceeding involving willful and contumacious failure to pay child support, a court may sentence the contemner to jail for a specified period, provided the court order permits the contemner to purge himself or herself of contempt and be released from jail upon payment of a reasonable amount of money toward the back child support. See,
Shillitani v. United States,
We next turn to the issue of whether the district court’s sanction order fixed a definite and reasonable sum of money for Maddux to pay toward his delinquent child support so that he could purge himself of contempt. To be reasonable, the amount of money required to be paid for a contemner to purge himself or herself of contempt of court must be within the contemner’s ability to pay. See
Shillitani
v.
United States, supra.
In that regard, the trial court may take into consideration not only the assets and financial condition of the contemner and the contemner’s ability to raise money, but also the contemner’s ability to earn money through a work release program while the
*244
contemner serves the coercive sanction in jail. If a contemner complains that he or she does not have the ability to comply with the purge order, the burden is upon the contemner to prove that inability. See
United States v. Rylander,
Since this court is vacating the punitive sanction imposed upon Maddux by the trial court and the cause is being remanded for imposition of a proper coercive sanction, the contempt proceeding here resumes its character as a civil proceeding. As previously stated, the imposition of a coercive sanction is never final and may not be attacked by direct appeal. As a result, we need not address Maddux’s assignments of error.
MODIFICATION OF CHILD SUPPORT
In her cross-appeal, Maddux’s ex-wife assigns as error the trial court’s modification of child support payments retroactive to the date the application to modify was filed. She also asserts that it was error to modify the order at a time when Maddux was in arrears on the payment of his child support obligation.
The general rule in Nebraska has been to allow a modification of a child support order prospectively from the time of the modification order itself. Throughout the past few decades, we have repeatedly stated the rule that when a divorce decree provides for the payment of stipulated sums monthly for the support of a minor child or children, contingent only upon a subsequent order of the court, such payments become vested in the payee as they accrue. Generally, the courts are without authority to reduce the amounts of such accrued payments. See,
Wassung
v.
Wassung,
In
Wassung, supra,
the defendant had asked to be relieved of liability for payments which had accrued since his December 1937 application for modification of child support. This court upheld the lower court decision which granted a modification, but limited it prospectively to amounts due after April 1939. The court stated that it was without authority to reduce the amounts retrospectively. “ ‘[T]he modifying decree relates to the future only
and from the time of its entry!
” (Emphasis supplied.)
Wassung, supra
at 443,
Upon occasion, depending upon the equities involved, this court has approved modification of a child support order retroactive to the filing date of the application for modification. In
Goodman
v.
Goodman,
There have been other circumstances in which a retroactive modification was allowed. See, e.g.,
Smith
v.
Smith,
In Nebraska, dissolution of marriage cases are equitable in nature.
Ohler v. Ohler,
In those cases where we have permitted reduction in child support retroactive to the date of filing the petition, the payor generally had acted in good faith in attempting to meet the payor’s obligation to pay child support. That cannot be said for Maddux.
During a 21/2-year span, from October 1986 to February 1989, Maddux earned in excess of $27,000, but paid only $1,050, or a mere 4 percent, of his gross income for the support of his five minor children. The chronology of events reflects that Maddux made most of his payments during that 2V2-year span in response to contempt proceedings. Maddux would tender a token payment followed by a lengthy timespan in which Tanya received nothing by way of child support, and the process would begin again. In the summer of 1988, for 3 months, Maddux earned $2,000 gross per month, with take-home pay of $1,600. During the same period, he paid only a total of $600 toward his child support obligation. For the calendar year 1988 Maddux’s income was in excess of $12,000, while his total payment on child support for his five children was $700. At the time of the modification hearing, Maddux was delinquent in his child support payments in excess of $42,000. The record further reflects that he had never maintained health insurance on his five children as he was ordered to do. That chore fell upon Tanya’s parents. The meager amounts Maddux paid on his child support obligation, coupled with the timing of those payments, reflect that Maddux was not acting in good faith. Maddux, at the time of the modification of child support hearing, did not enter the trial court with clean hands. On the other hand, Tanya, unlike the payees in some of the cases wherein we granted retroactive reductions in child support, *247 walked into the court with clean hands. The balance of equities in this case precludes Maddux from obtaining a modification of child support payments retroactive to the date he filed his application for modification.
Tanya’s second assignment of error on cross-appeal is without merit. She argues that under
Voichoskie
v.
Voichoskie,
In this case, as in Voichoskie v. Voichoskie, supra, the paying father has alleged an inability to make the payments ordered and alleged a change in circumstances since the time of the original order. In Voichoskie, we held that was sufficient for the application to be heard on its merits. The record here reflects that due to a substantial change in circumstances Maddux was entitled to a reduction in his child support obligation. While Maddux’s unclean hands prevent him from obtaining a retroactive reduction, such should not be invoked to bar him from a prospective reduction in child support. Tanya’s second assignment of error is meritless.
The punitive sanction imposed in this case is vacated, and this cause is remanded to the district court with instructions to impose a civil sanction in connection with its finding that Maddux is in contempt of that court. The trial court’s order reducing child support is hereby modified to affect only those support payments coming due after February 16,1989.
Affirmed in part as modified, and in part REVERSED AND REM ANDED WITH DIRECTIONS.
