Short answer: A California dissolution (divorce) ends the marriage. Legal separation can establish support, property, debt, and parenting orders while the parties remain married. Annulment, more precisely a nullity judgment, requires proof that the marriage was legally invalid under a recognized ground. Summary dissolution is a simplified dissolution available only to couples who meet every statutory condition. Bifurcation separates one issue from the rest of the case; bifurcated marital status can result in single status before all financial or parenting issues are finished.

The choices at a glance

Proceeding	What it is designed to do	Does it end marital status?
Dissolution	End the marriage and resolve remaining issues through agreement or court process	Yes, when judgment is entered
Legal separation	Obtain family-law orders while remaining married	No
Nullity or annulment	Establish that the marriage was invalid under a statutory ground	Yes if judgment is entered
Summary dissolution	Use a streamlined process for qualifying couples	Yes, when completed
Bifurcation	Decide a separable issue before the rest of the case	Only if marital status is bifurcated and ordered
Single status	The marital-status result of an entered dissolution, nullity, or qualifying bifurcation order	Yes

These labels describe legal functions, not shortcuts. The California Courts divorce guide and current Family Code provisions should be checked before selecting a path.

Dissolution compared with legal separation

A dissolution case can address property, debts, support, custody, and other issues and ultimately terminates marital status. California’s six-month waiting period is a minimum period before marital status can end; it is not a promise that the entire case will be completed in six months. The parties may still have unresolved disclosures, valuation, support, custody, or judgment issues.

Legal separation leaves the parties married but can allow the court to address many of the same practical issues. People sometimes consider it when residency for dissolution has not yet been met, when maintaining marital status affects benefits or insurance, or when they are not ready to end the marriage. A legal-separation judgment does not automatically become a divorce judgment. A separate conversion or dissolution process may be needed, and the consequences should be reviewed before filing.

What makes a nullity different?

An annulment is not simply a faster or more favorable divorce. A nullity proceeding asks the court to determine whether the marriage was invalid under a recognized legal ground, such as certain defects in consent, capacity, or prohibited marriage circumstances. The available ground, evidence, and time limit can depend on the facts and the legal basis asserted.

A short marriage, lack of property, or mutual desire to avoid divorce does not itself establish a nullity. Do not plead or rely on a ground without checking the current statute and obtaining advice about proof and timing. A nullity can also affect what relief is available, so it should not be selected for its label alone.

Summary dissolution is narrower than ordinary divorce

Summary dissolution is designed for qualifying couples who satisfy all statutory conditions. Eligibility can depend on length of marriage, property and debt limits, children, support, residency, agreement, and other requirements. Every condition matters. If a couple does not qualify, ordinary dissolution or another procedure may be necessary.

The streamlined path still requires accurate disclosures and careful attention to official instructions. The court does not treat a couple as eligible merely because the marriage was brief or both people agree. Compare the current forms and disclosures guide with the facts before signing.

Bifurcation and early single status

Bifurcation lets the court decide a separable issue before the remaining issues are resolved. A request for bifurcated marital status may be useful when one party needs the status issue decided earlier, but it does not automatically divide the home, determine support, value a business, or create a parenting plan. Statutory conditions and safeguards may apply, including requirements protecting the other party from certain consequences.

Once marital status is terminated, the remaining case still needs a judgment or orders addressing unresolved property, debt, support, custody, fees, and other issues. Check the proposed order carefully. “Single status” is a legal result, not a statement that every issue between the parties is settled.

How to choose a starting point

Begin with the objective, then test eligibility and consequences:

Decide whether the immediate goal is ending marital status, obtaining temporary orders, preserving marital status, or challenging validity.
Confirm residency, jurisdiction, service facts, children, property, debt, and existing orders.
Identify insurance, tax, immigration, estate-planning, benefit, and retirement consequences.
Determine whether the simplified process or a nullity ground actually applies.
List what remains unresolved if marital status is decided first.
Read current Judicial Council forms and county filing instructions.

Do not move property, cancel insurance, relocate a child, or sign a status agreement simply because another proceeding appears quicker. A family-law attorney and, where appropriate, a tax, immigration, benefits, or estate professional can address issues outside one person’s legal advice.

Practical next steps

Save the petition, summons, proofs of service, disclosures, agreements, orders, and judgment. Calendar response and hearing dates. County filing logistics can differ even though the governing law is statewide; Bay Area readers in San Francisco, San Mateo, Santa Clara, Alameda, Contra Costa, Marin, Sonoma, or Napa counties should use the assigned Superior Court’s current instructions. For process context, see California divorce eligibility, filing strategy, and timelines and How long does a California divorce take.

General information only. Current statutes, forms, deadlines, case law, local procedure, and the facts of the marriage require attorney review before filing or signing.

Questions that often change the answer

Can spouses remain married after filing? Yes. A legal-separation judgment does not end marital status. A dissolution case does not end status until the court enters the judgment effective under its terms. Filing a petition is not the same as becoming single.

Is an annulment better than a divorce? “Better” is not a legal category. A nullity requires a qualifying ground and proof. If the facts do not meet that ground, the court cannot grant a nullity merely because the marriage was short or the parties prefer the label.

Can bifurcation resolve everything? No. It separates an issue. A bifurcated status order can leave property, debt, support, custody, fees, and disclosure issues for later orders or judgment.

Can a legal separation later become a divorce automatically? Do not assume that it does. Confirm the required filing, service, judgment, and current court procedure. The timing and effect may depend on the existing judgment and the relief still needed.

Consequences to discuss before filing

Marital status can affect health insurance eligibility, tax filing, retirement benefits, immigration strategy, estate documents, beneficiary designations, and the ability to remarry. A court case can also affect fiduciary duties, disclosure, property management, and support. These topics do not all have the same answer, and a family-law form cannot substitute for benefits, tax, immigration, or estate advice.

Make a comparison chart for each path: eligibility, status, property, support, children, disclosures, timing, expense, and unresolved risk. Identify which assumptions need a document or professional confirmation. That preparation often matters more than selecting a label quickly.
