Why your divorce depends almost entirely on what state you're in

If you’ve been Googling answers to your divorce questions and keep getting conflicting information, there’s a good reason: divorce is almost entirely state law. What’s true in California is often the opposite of what’s true in Texas, and an article that doesn’t say which state it’s about is at best half right anywhere.

This is also why we keep asking what state you’re in. It’s not a tracking thing. It’s the single most important variable in your case.

Here’s why.

Federal law barely touches divorce

The federal government has authority over a few specific things that touch divorce — federal tax filing status, certain retirement-account splits (QDROs), military pensions under the USFSPA, interstate enforcement of child support, parental kidnapping. Beyond those edges, every part of your case is decided by the state where you file.

That includes:

• Whether you qualify to file at all (residency)
• How long until the divorce can be finalized (waiting periods)
• How property and debts get divided
• How child support is calculated
• Whether and how much spousal support gets paid
• The factors courts use to decide custody
• The exact forms, deadlines, and procedures

Each of these can vary dramatically between two neighboring states.

Residency: can you even file here?

Every state has a residency requirement — a minimum amount of time you must have lived in the state before its courts will accept your divorce petition.

If you moved recently, this is the first question to answer. Filing in a state where you don’t meet residency can get your petition dismissed.

Waiting periods: how long until it’s final?

After you file, many states impose a waiting period before the divorce can be finalized — a built-in cooling-off pause. California has a six-month minimum. Texas has 60 days. Some states have no waiting period at all once paperwork is complete.

This is why even an uncontested divorce can take longer than it "should." The papers may be done, but the calendar isn’t.

Property: the biggest single state divide

This is the rule that can change the math of your divorce by hundreds of thousands of dollars.

Equitable distribution states (most of the country) divide marital property fairly, which doesn’t always mean equally. A judge weighs incomes, contributions, length of marriage, future earning capacity, and so on. The split could be 50/50, 60/40, even 70/30.

Community property states (nine of them — California, Texas, Arizona, Nevada, Washington, Idaho, New Mexico, Wisconsin, Louisiana) start from a 50/50 baseline for anything earned or acquired during the marriage. There’s less judicial discretion. What’s "community" is split down the middle; what’s "separate" stays with whoever brought it in.

A higher-earning spouse in a community-property state often pays out more property than they would in an equitable-distribution state. A lower-earning spouse often gets less spousal support (because the property split is already more generous to them). Same family, same income, very different outcome depending on which side of a state line.

Child support: every state has its own formula

Every state has a child-support formula codified into law, and every state’s formula is different.

Most use one of two approaches:

• Income shares. Both parents’ incomes are added together; the obligation is computed; each parent owes their proportional share. The parent who has the kids less of the time pays their share to the parent who has them more.
• Percentage of obligor’s income. A flat percentage of the paying parent’s income, scaling with number of children. Simpler, but less responsive to the other parent’s income.

The result is that the same family, with the same incomes and parenting schedule, can owe meaningfully different child-support amounts in different states. State court websites usually publish a calculator that runs the official formula — if you want a real number for your situation, that’s where to find it.

Custody defaults

States also vary in their starting assumption about custody. Some have a presumption favoring joint legal custody unless there’s a reason against it. Some have a presumption favoring joint physical custody (much rarer). Some have no presumption at all and decide every case on its facts.

These presumptions matter because they shift who has to prove what. A state with a joint-custody presumption means the parent arguing against joint custody has to make the case. A state with no presumption puts both parents on equal footing from the start.

Even the vocabulary changes

A small but disorienting fact: the same idea has different names in different states.

• Alimony in some states is called spousal support in others and maintenance in a few (notably Illinois and New York).
• A petition in most states is called a complaint in some.
• A decree in older state codes is called a judgment of dissolution in newer ones.

Same legal animal, different nameplate.

What this means for you

When you read general divorce content (this site included), apply a small mental filter: does this map to my state? If an article says "in most states X is true," check whether your state is in the majority. If an article makes specific procedural claims and doesn’t name your state, treat it as a sketch, not a recipe.

The good news: state court websites are almost universally free and surprisingly usable. Searching "[your state] divorce self-help" usually gets you to the official forms, the official fees, the official residency requirements, and often a step-by-step procedural guide. That is the authoritative source for your case.

Everything else, including this article, is the map. The state court site is the territory.
