About Family Law
Family law covers legal matters arising from family relationships: divorce, child custody and visitation, child support, spousal support (alimony), adoption, paternity, domestic violence protective orders, and prenuptial / postnuptial agreements. Family courts in each state apply that state's family code; there is no federal family law.
Divorce requires only a residency period in the state (usually 6 weeks to 1 year) and a legally accepted ground. Every state now offers no-fault divorce based on irreconcilable differences. Some states retain optional fault grounds (adultery, cruelty, abandonment) which can affect property division and alimony in specific circumstances.
Property division follows one of two systems:
- Community property (9 states including California and Texas) — assets and debts acquired during the marriage are presumed to be owned 50/50, regardless of who earned or incurred them.
- Equitable distribution (the remaining 41 states) — courts divide assets fairly based on multiple factors including each spouse's contribution, length of marriage, and future earning capacity. Equitable does not necessarily mean equal.
Child custody is decided under the best interests of the child standard. Modern courts strongly favor frequent and continuing contact with both parents and routinely order joint legal custody (decision-making) even when physical custody is primarily with one parent. Custody orders can be modified later if a substantial change in circumstances occurs.
Child support is calculated by formula in every state, usually based on both parents' gross incomes, the number of children, and the percentage of overnights each parent has. State guidelines produce a presumptive amount that courts deviate from only with written findings. Child support is enforced aggressively through state-run agencies, wage withholding, license suspension, and contempt proceedings.
Spousal support (alimony) rules vary widely. Most states consider length of marriage, income disparity, age and health, and earning capacity. Lifetime alimony is increasingly rare except in marriages over 20 years.
Most family law matters can be resolved through mediation, collaborative law, or uncontested filings, which are usually cheaper and faster than litigation. Many family courts now require mediation before scheduling a contested hearing.
