A reservation of jurisdiction made this temporary support order unappealable: Sterndahl v. Sterndahl
Is a temporary spousal support order appealable in California? Usually, but not when the trial court expressly reserves jurisdiction to modify it retroactively. In Sterndahl v. Sterndahl, a published decision, the Second District, Division Three, dismissed a husband's appeal from an order refusing to reduce his $45,000 monthly support, and declined to treat the appeal as a writ petition.
What happened in Sterndahl v. Sterndahl
Susanne Sterndahl filed for dissolution of the parties' 16-year marriage in September 2023. In April 2024 she requested temporary spousal support, and the trial court ordered Dennis Sterndahl to pay $45,000 a month. He did not appeal that order.
In October 2024 Dennis asked the court to modify the award. He said he had sold his business, was retiring, and could not continue paying at the ordered amount. Susanne asked for an increase to $58,266, arguing the sale proceeds would generate substantial income; a document prepared by Dennis's forensic accountant put those proceeds at approximately $36.7 million.
At the February 2025 hearing, the court found Dennis had not shown a change in circumstances based on an inability to pay, and it also denied Susanne's request for an increase. Then came the exchange that decided the appeal. Dennis's counsel argued it was "more fair" for the award to be retroactively modifiable and asked the court to clarify whether it was retaining jurisdiction. The court answered: "I’ll reserve retroactivity." Its written order "reserve[d] jurisdiction from November 1, 2024 to time of trial in order to retroactively modify the amount of temporary spousal support."
Dennis appealed the order, and Susanne moved to dismiss. While the appeal was pending, the trial judge (the parties had agreed to try the matter before a private judge) declined to modify the temporary award, the trial court entered judgment, and Dennis appealed from the judgment as well.
Is a temporary spousal support order appealable in California?
Ordinarily, yes. The court began with In re Marriage of Gruen (2011) 191 Cal.App.4th 627: "A temporary support order is operative from the time of pronouncement, and it is directly appealable." That rule is a family-law exception to the one final judgment rule, and it rests on the order being dispositive of the parties' rights on the collateral matter. The opinion also recounts the other side of Gruen: there, the trial court exceeded its jurisdiction by retroactively modifying a temporary support order that the husband had not appealed.
In re Marriage of Freitas (2012) 209 Cal.App.4th 1059 supplies the exception. When the trial court expressly reserves jurisdiction to amend the award, the parties' clear expectation is that the award is not final, and so it is not fully dispositive of their rights.
Why the reservation of jurisdiction made the order nonappealable
The court held that the reservation here worked just as it did in Freitas. The statements at the hearing and the written order created a "clear expectation" that the award from November 1, 2024, to the start of trial was "not final as to these months." The court's conclusion was direct:
We therefore conclude that the order denying Dennis’s request was nonfinal and not appealable.
Dennis argued that later events, the trial judge's refusal to modify the award and the entry of judgment, made the order final. The court called that argument "an implicit concession" that the order was not dispositive of the parties' rights when it was issued, so it was not separately appealable. Nor was Dennis left without a remedy: he may raise his challenge in his pending appeal from the judgment, which rendered the order final. In a footnote, the court explained that his second notice of appeal could be read to encompass the order even though it did not separately identify it.
No "deemed" appealability, and no writ
Dennis also asked the court to treat his appeal as a petition for writ of mandate, as the Court of Appeal did in Last v. Superior Court (2023) 94 Cal.App.5th 30. Last had acknowledged that a reservation of jurisdiction usually renders a temporary support award nonfinal, yet suggested the collateral order doctrine supported deeming the order appealable, before resolving any doubt by treating the appeal as a writ petition. Division Three declined to follow that path:
We find no basis to “deem” the order at issue here to be appealable.
It also declined to treat the appeal as a writ petition. That discretion "should be exercised only in unusual circumstances," such as when dismissal would lead to unnecessary trial proceedings, or when every other issue has been resolved and all parties strongly urge a decision. None of those circumstances was present. The appeal was dismissed, with costs on appeal to Susanne.
What Sterndahl means in practice
A reservation of jurisdiction is a trade. It keeps the amount open for both sides; the court at the hearing warned that it "exposes both of you to potential risks." But it also changes the appellate path. An order the trial court has left open to revision at trial is not a final collateral order, and the challenge waits for the appeal from the judgment.
So before asking for, or agreeing to, a reservation, it is worth knowing what it does to the right to appeal now. And when an interim order looks appealable, the question is not only what kind of order it is, but whether the trial court left it open.

Key takeaways
- A temporary spousal support order is ordinarily directly appealable as a collateral order under In re Marriage of Gruen.
- When the trial court expressly reserves jurisdiction to modify the award retroactively, the order is nonfinal and not separately appealable.
- Arguing that later rulings and the judgment made the order final was treated as an implicit concession that it was not dispositive when issued.
- The court declined to follow the suggestion in Last v. Superior Court that such an order can be deemed appealable, and it refused to treat the appeal as a writ petition.
- The husband may raise his challenge to the support order in his pending appeal from the judgment.
Why appeals like this one need an appellate lawyer
The decisive moment in Sterndahl came at a support hearing in February 2025, long before any brief was written. The husband's side argued for a reservation of retroactivity, and the court granted it. That kept the amount open, and it also meant the order could not be appealed on its own. The result was an appeal the Court of Appeal had no jurisdiction to decide, a dismissal, and an award of the other side's costs on appeal.
An appellate lawyer looks at a trial-court request from the other end. Before a reservation is sought or accepted, the question is what it does to appealability. When an order issues, the question is whether it is final now, reviewable only with the judgment, or reviewable only by writ, and what starts the clock. Those calls are made early, and they are made in the trial court record. If you are facing a support ruling or any interim order you may need to challenge, talk to an appellate lawyer early, before a deadline runs or a record is lost.
