California family law recognizes three primary types of marital actions: dissolution, legal separation, and nullity. Each serves a different legal purpose and is appropriate depending on the circumstances of the parties. Understanding these distinctions is essential when determining how to proceed with ending or restructuring a marital relationship.

A dissolution of marriage, commonly known as divorce, is the most frequently used action. Its defining feature is that it terminates the marital status entirely, restoring both parties to the status of unmarried individuals. This allows each person to remarry and fully separate their legal and financial lives. Dissolution can be pursued either as a standard dissolution or, if certain requirements are met, as a summary dissolution, which is a simplified process.

A legal separation, by contrast, does not terminate the marriage. Instead, it allows the parties to divide property, address custody and support, and otherwise formalize their separation while remaining legally married. This option is often chosen for personal, religious, or financial reasons. For example, parties may wish to retain health insurance benefits, maintain eligibility for certain military or Social Security benefits, or avoid the finality of divorce for personal beliefs.

The third type, nullity, differs significantly from the other two. A nullity declares that a marriage was never legally valid or should be treated as if it never existed. This may apply in cases involving fraud, incapacity, incest, or bigamy. Nullity can be based on either a void or voidable marriage, depending on the underlying circumstances.

In addition to these actions, California law also provides procedures for terminating registered domestic partnerships (RDPs), which largely mirror marital dissolution processes. In some cases, administrative termination may be available, but if eligibility requirements are not met, parties must proceed through court just like married couples.

Ultimately, the choice among these options depends on the parties’ goals, eligibility, and legal strategy. While dissolution is the most common path, legal separation and nullity provide important alternatives in specific situations. Each option carries unique legal consequences, particularly regarding marital status, property division, and support rights. Careful consideration is necessary to ensure the chosen action aligns with the parties’ needs and long-term objectives.
