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 Delaware, dissolution of marriage is synonymous with divorce. The state allows for both fault-based and no-fault divorces. For a no-fault divorce, the spouses may cite irretrievable breakdown of the marriage as the reason for seeking a divorce. Delaware does not have a specific expedited process like California's summary dissolution, but it does have a procedure for an uncontested divorce. An uncontested divorce in Delaware is one where both parties agree on all major issues such as alimony, child support, custody, and division of property. To file for an uncontested divorce, the couple must have a separation agreement in place and must have been separated for at least six months. The relevant statutes governing divorce in Delaware can be found in Title 13 of the Delaware Code, which covers Domestic Relations.
