The two systems, explained plainly
When you get married, your state's law becomes the default rulebook for your financial relationship. Without a prenup, that rulebook determines what property is "yours," what's "ours," and what happens to it if you divorce. There are two main systems in the United States.
Community property (9 states)
In community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — most assets and income acquired during the marriage belong equally to both spouses, regardless of who earned or purchased them. If you earn a salary, half of it is automatically your spouse's. If your spouse buys stock with their paycheck, half of that stock is yours.
Property owned before the marriage, and gifts or inheritances received by one spouse, generally remain separate property. But the line blurs quickly: if you deposit separate property funds into a joint account, they can become community property. If your separate-property business increases in value during the marriage due to your work efforts, that appreciation may be community property.
Equitable distribution (all other states + DC)
In equitable distribution states, courts divide marital property "fairly" — but fairly doesn't mean 50/50. Judges consider factors like the length of the marriage, each spouse's earning capacity, contributions to the marriage (including non-financial contributions like raising children), and economic circumstances. In practice, long marriages often result in roughly equal splits, but shorter marriages, disparate incomes, or unique circumstances can produce very different outcomes.
Why this matters for your prenup
A prenup lets you override your state's default system. This is powerful in both directions: couples in community property states may want a prenup that keeps certain earnings or assets separate. Couples in equitable distribution states may want a prenup that creates more predictability — essentially creating their own version of a 50/50 rule, or protecting specific assets from being subject to a judge's discretion.
For example, if one partner owns a business in California (a community property state), the business's growth during the marriage could be subject to community property rules without a prenup. A well-drafted prenup can specify that the business remains separate property even if its value increases.
Special considerations for community property states
Moving between states complicates things. If you marry in Texas (community property) and move to New York (equitable distribution), the property you acquired in Texas may still be treated as community property in a New York divorce — or it may not, depending on how New York handles "quasi-community property." If you expect to move states, a prenup is especially important for establishing clear, portable rules about your financial relationship.
Louisiana's community property system is also unique: it's based on the Napoleonic Code and has quirks that differ meaningfully from other community property states. Louisiana residents especially benefit from explicit prenuptial terms.
