“She Makes Twice What I Do — So What’s the Number?”
People expect spousal support to come from one formula. It doesn’t. California runs two different systems — a guideline calculator for temporary support while the case is pending, and a discretionary, factor-driven analysis for long-term support in the judgment — and they can produce very different numbers. Ava and Michael take both sides, then the law.
His Side, Her Side — the Same Facts, Two Views
His Side (Michael):
“She earns about double what I do. Whatever the calculator spits out, it should reflect that she’s the higher earner, not me.”
Her Side (Ava):
“And the final number should reflect the whole marriage — the standard of living, our assets, and how long we were together — not just this month’s paychecks.”
His Side (Michael):
“Right, so let’s be clear which system we’re in — the temporary one or the long-term one — because they don’t work the same way.”
Her Side (Ava):
“Exactly. Getting that distinction right is half the fight.”
Ava Asks, Michael Answers — The Two Systems, Plain English
Ava:
Is there one formula for spousal support in California?
Michael, Esq.:
No — there are two systems. Temporary (pendente lite) support, paid while the case is pending, is usually set by a local guideline and a computer program like DissoMaster based mainly on the two incomes. Long-term support in the judgment is not set by a formula at all.
Ava:
What is DissoMaster?
Michael, Esq.:
It’s a software calculator courts use for temporary support that mechanically applies the parties’ incomes to a local schedule. It’s meant to keep the status quo until the case is resolved — a quick, income-driven number.
Ava:
So the long-term number comes from the same calculator?
Michael, Esq.:
No — and this matters. Under In re Marriage of Schulze, it is reversible error to set long-term spousal support with DissoMaster; the guideline can’t even be used as a benchmark. Long-term support must be decided by weighing the Family Code section 4320 factors.
Ava:
What are those 4320 factors?
Michael, Esq.:
A list the judge must weigh — each spouse’s earning capacity, the marital standard of living, each party’s assets and obligations, the ability of the paying spouse to pay, the needs of each, the duration of the marriage, and the goal that a supported spouse become self-supporting within a reasonable time, among others.
Ava:
So “she makes twice as much” — does that flip the result?
Michael, Esq.:
It’s a major factor in both systems, because relative income drives the temporary calculation and earning capacity and ability to pay are central 4320 factors. A higher-earning spouse can end up the payor. But it’s weighed with everything else — not decided by that fact alone.
Ava:
Why do the two numbers differ so much?
Michael, Esq.:
Because the temporary calculator is a blunt income formula, while the long-term number is a judge’s discretionary weighing of the whole marriage. Knowing which system you’re in — and arguing the right factors — is where cases are won or lost.
What to Do
California doesn’t have one spousal-support formula — it has two systems. Temporary support while the case is pending is a guideline calculation (DissoMaster) driven mainly by the two incomes; long-term support in the judgment is a discretionary weighing of the Family Code section 4320 factors, and under Marriage of Schulze the calculator can’t be used for it. Relative income — like one spouse earning double — is a major factor in both, but never the whole story.
