How Divorce Works: Property Division, Alimony, and Child Custody

What Is Divorce?

Divorce (called dissolution of marriage in some states) is the legal termination of a marriage by court order. It resolves four major issues: division of marital property and debts, spousal support (alimony), child custody and parenting time, and child support. Divorce law is primarily state law, and the rules vary significantly by jurisdiction.

Grounds for Divorce

Every state now has no-fault divorce, allowing divorce on grounds of "irreconcilable differences" or "irretrievable breakdown of the marriage" without proving the other spouse did anything wrong. Most divorces proceed on no-fault grounds.

Fault-based grounds (adultery, cruelty, abandonment) still exist in some states and can be relevant to alimony determinations, but are increasingly rare as the basis for divorce itself.

Contested vs. Uncontested Divorce

• Uncontested divorce: Both spouses agree on all issues — property, support, custody. Generally faster, less expensive, and less emotionally damaging. Can often be completed for a few hundred to a few thousand dollars. Many uncontested divorces don't require court appearances.
• Contested divorce: Spouses disagree on one or more issues requiring court resolution. Contested divorces can cost $15,000–$50,000+ per spouse in attorney fees, take 1–3 years, and create lasting conflict — especially harmful when children are involved.
• Mediation: A neutral mediator helps spouses negotiate agreements on contested issues. Less adversarial and cheaper than litigation; agreements reached in mediation then become court orders.
• Collaborative divorce: Both spouses hire collaborative law-trained attorneys who commit to resolving issues without litigation.

Division of Marital Property

How assets are divided depends on your state:

Equitable Distribution States (Most States)

Courts divide marital property "equitably" — fairly but not necessarily equally. Factors include: length of marriage, each spouse's economic circumstances, contributions to the marriage (financial and non-financial including homemaking), and the standard of living during marriage. Most equitable distribution states reach roughly 50/50 in practice for long marriages.

Community Property States

Nine states (California, Texas, Arizona, Nevada, New Mexico, Idaho, Louisiana, Washington, Wisconsin) treat most assets acquired during marriage as jointly owned 50/50. Division is generally equal.

Marital vs. separate property: Property owned before marriage, received as inheritance, or gifted individually is generally separate property not subject to division. Commingling separate and marital property (depositing an inheritance into a joint account) can convert it to marital property.

Spousal Support (Alimony)

Alimony is financial support paid by one spouse to the other after divorce. Not automatic — awarded based on factors including length of marriage, both spouses' income and earning capacity, standard of living during marriage, and one spouse's need and the other's ability to pay.

• Temporary alimony: Paid during the divorce proceedings
• Rehabilitative alimony: Time-limited support to allow the recipient to gain education or job skills
• Permanent alimony: Ongoing support, typically in long marriages where one spouse has significantly lower earning capacity; increasingly rare and often modifiable upon cohabitation or remarriage

Child Custody

Courts determine custody arrangements based on the best interests of the child — considering the child's relationship with each parent, each parent's ability to meet the child's needs, stability, and (for older children) the child's preferences.

• Legal custody: Decision-making authority for education, healthcare, religion. Typically shared (joint legal custody) unless one parent is absent or unfit.
• Physical custody: Where the child lives. Can be sole (child primarily with one parent) or joint (significant time with both). Joint physical custody has become more common as research supports children's benefits from maintaining relationships with both parents.

Child Support

Child support is calculated using state-specific formulas based primarily on both parents' incomes and the custody arrangement. Federal law requires each state to have child support guidelines. Support continues until the child reaches the age of majority (18 or graduation from high school, in most states). Support can be modified if circumstances change significantly.
