Dissolution of marriage is generally another term for divorce—but in some states it specifically refers to an uncontested divorce—a no fault divorce with a written separation agreement. And in California, for example, there is a summary dissolution that provides an expedited process under limited circumstances (California Family Code §2400).

The laws regarding various methods for dissolving a marriage are usually located in a state’s statutes—often in the Family Code or Domestic Relations Code.

In Oregon, dissolution of marriage is indeed another term for divorce. Oregon is a no-fault divorce state, meaning that the only ground for divorce is 'irreconcilable differences' that have caused the irreparable breakdown of the marriage (ORS 107.025). The process for dissolution of marriage can be contested or uncontested. An uncontested divorce, where both parties agree on all terms including division of property, spousal support, and child custody, can be more straightforward and may not require a court hearing. Oregon does not have a summary dissolution process like California, but the state does offer a simplified divorce procedure known as 'Summary Dissolution' for couples who meet certain criteria, such as having been married for less than 10 years, having no children together, and having limited property and debts (ORS 107.485). The forms and instructions for summary dissolution are available from the Oregon Judicial Department. It's important to note that even in an uncontested divorce, legal requirements must be met, and it may be advisable to consult with an attorney to ensure that all legal aspects are properly addressed.
