Divorce in the United States is a matter of state

Rather than federal law. In recent years, however, more federal legislation has been enacted affecting the rights and responsibilities of divorcing spouses. The laws of the state(s) of residence at the time of divorce govern; all states recognize divorces granted by any other state. All states impose a minimum time of residence. Typically, a county court’s family division judges petitions for dissolution of marriages.

Before the latter decades of the 20th century, a spouse seeking divorce had to show cause and even then might not be able to obtain a divorce. The legalization of no-fault divorce in the United States began in 1969 in California, and was completed in 2010, with New York being the last of the fifty states to legalize it.[20][21] However, most states still require some waiting period before a divorce, typically a 1– to 2–year separation. Fault grounds, when available, are sometimes still sought. This may be done where it reduces the waiting period otherwise required, or possibly in hopes of affecting decisions related to a divorce, such as child custody, child support, or alimony. Since the mid-1990s, a few states have enacted covenant marriage laws, which allow couples to voluntarily make a divorce more difficult for themselves to obtain than in the typical no-fault divorce action.

Mediation is a growing way of resolving divorce issues. It tends to be less adversarial (particularly important for any children), more private, less expensive, and faster than traditional litigation.[22] Similar in concept, but with more support than mediation, is collaborative divorce, where both sides are represented by attorneys but commit to negotiating a settlement without engaging in may not be appropriate for all relationships, especially those that included physical or emotional abuse, or an imbalance of power and knowledge about the parties' finances.
