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 Rhode Island, dissolution of marriage is synonymous with divorce. The state allows for both fault-based and no-fault divorces. For a no-fault divorce, the parties must assert that irreconcilable differences have caused the breakdown of the marriage or that they have lived separate and apart without cohabitation for at least three years. Rhode Island does not have a summary dissolution process like California. Instead, the state has a nominal divorce process, which can be relatively quick if the parties agree on all terms, and a contested divorce process, which is used when the parties cannot agree and may require court intervention to resolve disputes. The laws governing divorce in Rhode Island can be found in Title 15 of the Rhode Island General Laws, which covers Domestic Relations.
