If you’re trying to understand the legal options available when a marriage isn’t working, California offers three distinct paths: annulment, legal separation, and divorce. Each one comes with different legal outcomes, eligibility rules, and long-term implications, especially around finances, family decisions, and your future.
The right choice depends on your situation: whether the marriage was legally valid, whether you want to remain married for specific reasons, and whether you’re ready to formally end the relationship.
Here’s what each option means under California law, and how to determine which one may fit your goals.
What Is the Difference Between Annulment, Divorce, and Legal Separation in California?
Annulment voids a marriage, treating it as though it never legally existed. Divorce ends a valid marriage and restores both parties to single status. Legal separation allows spouses to live apart under a court order while remaining legally married.
Here’s a side-by-side look:
| Legal Option | Ends Marriage? | Can Remarry? | Legal Grounds | Common Reasons | Filing Requirements |
| Divorce | Yes (marriage dissolved) | Yes | No-fault in CA (irreconcilable differences), incurable insanity | Permanent end to marriage | Must meet residency requirements (6 mo. CA, 3 mo. county) |
| Legal Separation | No | No | Irreconcilable differences or legal cause | Religion, health insurance, immigration, cooling-off period | No CA residency required |
| Annulment | Yes (marriage voided, needs a court order) | Yes | Must prove marriage was never valid under specific grounds in the law | Bigamy, fraud, mental incapacity, force | Strict time limits or, for some grounds, no time limit (see below) |
When Should You Choose Divorce?
You should choose divorce if your marriage was legally valid and you want to end it permanently.
California is a no-fault divorce state, meaning you don’t have to prove wrongdoing or blame. You only need to cite “irreconcilable differences” or, in rare cases, “incurable insanity.”
Divorce restores your legal single status, allowing you to remarry, divide property, determine support, and settle custody issues. But it’s not immediate.
California requires:
- Residency: At least 6 months in the state and 3 months in the county where you file (Fam. Code §2320)
- Waiting period: Your divorce can’t be finalized any sooner than 6 months after the non-filing spouse is served
For many, divorce offers the closure they need.
When Should You Choose Legal Separation?
Legal separation is a good option if you’re not ready to fully dissolve your marriage, whether for religious beliefs, cultural expectations, or practical reasons. It offers a structured way to live apart while remaining legally married. For some, it’s a faith-based decision. For others, it’s a financial one.
This can be an especially useful option when:
- You or your spouse wants to keep certain benefits tied to marital status (like health insurance or tax filing options)
- You don’t meet the residency requirements for divorce yet, since legal separation has no minimum time requirement for living in California
- You’re considering reconciliation, but need clear boundaries and court protections in the meantime
It’s a common myth that legal separation is “informal” or “temporary.” In reality, it requires many of the same steps as divorce, including financial disclosures, custody/support decisions, and a court judgment. You’re still legally married at the end, unless you later convert the order to a divorce.
Legal separation can also be amended into a divorce case later, once you meet residency rules or feel ready to finalize things.
When Should You Choose Annulment?
You may want to file for annulment if you believe your marriage was never legally valid in the first place. California courts don’t grant annulments easily; you must meet very specific criteria under the law.
For example, annulment may be possible if:
- One spouse was already married to someone else (bigamy)
- The spouses were related by blood (incest)
- One or both spouses were underage and didn’t get proper consent
- There was fraud, force, or some physical or mental condition (such as incapacity) preventing proper consent
- One party lacked the mental capacity to understand what marriage entails
Unlike divorce, annulment isn’t about irreconcilable differences; it’s about proving that the marriage shouldn’t have been legal to begin with. That means the burden is on whoever is filing for annulment to prove one of these legal defects existed at the time of the marriage.
The court won’t simply grant an annulment because you regret getting married; there must be clear legal grounds and, in many cases, convincing evidence.
How Time Limits Affect Annulments in California
One of the most overlooked facts about annulment is that you can lose your right to file simply by waiting too long. Each ground comes with its own time limit, or “statute of limitations,” or, for some, no time limit:
| Reason for Annulment | Time Limit to File | Code Reference |
| Underage marriage | Before the underage party turns 22 | Fam. Code §2211(a) |
| Bigamy | Any time during both parties’ lifetimes | Fam. Code §2211(b) |
| Unsound mind | Before either party dies | Fam. Code §2211(c) |
| Fraud, coercion (force), physical incapacity | Within 4 years of discovering or experiencing it | Fam. Code §2211(d–f) |
Missing the deadline could mean you cannot get your marriage annulled, even if you would otherwise qualify.
And if property or children are involved, the court may invoke the putative spouse doctrine, meaning even if your marriage wasn’t legally valid, the court might still divide property or order support if one party reasonably believed the marriage was real.
How Legal Separation, Annulment, and Divorce Affect Your Taxes, Insurance, and Finances
Each legal path comes with different consequences for your financial planning, especially when it comes to taxes, insurance, and protecting assets.
Health Insurance
Legal separation may allow you to keep spousal health coverage, but it depends entirely on the rules of your plan. Some providers treat separation the same as divorce and will cut off benefits, while others continue coverage as long as you’re legally married.
Divorce, once finalized, almost always ends spousal benefits, though COBRA may offer temporary continuation at a higher cost. The best move? Check with your HR department or plan administrator before filing.
Taxes
The IRS bases your marital status on December 31 of the tax year. If you’re still legally married, even if separated, you may be able to file jointly or as “married filing separately,” depending on your circumstances. Once divorced, you’re considered single for tax purposes.
Because tax laws can be tricky and high-stakes, it’s wise to talk to a tax professional before finalizing any legal action.
Annulment Impacts
Annulments create a unique situation because the marriage is considered legally invalid. That means typical community property rules might not apply. Still, if one spouse believed the marriage was valid, the court can divide property and even award support under California’s putative spouse doctrine.
If you’re managing significant assets, timing your separation or divorce can influence everything from capital gains to retirement rollovers. Planning ahead, with legal and tax guidance, can make a meaningful difference.
Common Myths About Annulment, Divorce, and Legal Separation in California
Myth: Annulments are easier than divorce.
Truth: They’re often harder. You must prove your marriage was never valid, which can involve evidence, testimony, and legal complexity.
Myth: Legal separation is a casual or temporary fix.
Truth: It requires nearly the same paperwork and disclosures as divorce, and it results in a binding court order.
Myth: Annulments mean no property or support issues.
Truth: Courts may still step in under California’s putative spouse laws to ensure fairness, especially if children or shared property are involved.
How to Decide Between Annulment, Legal Separation, and Divorce
Here’s a simple framework:
- Choose annulment if your marriage wasn’t legally valid to begin with, and you can prove it.
- Choose legal separation if you want space, boundaries, or legal protections, but don’t want (or can’t get) a divorce yet.
- Choose divorce if your marriage was valid, but it’s time to move forward separately and permanently.
Each option carries different implications for your property, your children, your future, and your peace of mind.

FAQs on the Difference Between Annulment, Divorce, and Legal Separation
Why would you get a legal separation instead of a divorce in California?
You might choose legal separation if you want to live apart but remain married for reasons like health insurance, tax planning, or religious beliefs. It’s also an option if you don’t yet meet California’s divorce residency rules or want time before making a final decision.
How do annulment, divorce, and legal separation differ?
Annulment treats the marriage as though it never legally existed. Divorce ends a valid marriage and restores both parties to single status. Legal separation allows spouses to live apart under court orders while staying legally married — often for financial, cultural, or personal reasons.
Is it better to get a legal separation before a divorce?
It depends on your goals. Some people file for legal separation to maintain benefits or buy time before finalizing a divorce. Others start with separation because they don’t yet meet California’s divorce residency requirements. In many cases, a legal separation can later be amended into a divorce.
