Most people think annulment is just a faster version of divorce. It’s not. These are two completely different legal actions with different rules, different consequences, and different outcomes.
A divorce ends a valid marriage. An annulment says the marriage was never legally valid in the first place. That distinction sounds simple, but it changes everything — from how property gets divided to whether you’re eligible for Social Security benefits, how the IRS treats your tax returns, and what happens to your immigration status.
Every state handles annulment differently. Some states have detailed annulment statutes. Others — like Florida — have no annulment statute at all and handle the entire process through case law. And a handful of states use unusual rules that can catch people off guard, like Georgia’s absolute bar on annulment when children are involved.
Here’s how annulment actually works, how it compares to divorce, and when a marriage can be declared legally void.
- A divorce ends a valid marriage going forward — an annulment declares the marriage never legally existed, retroactive to the date of the ceremony.
- Grounds fall into two categories: void marriages (bigamy, incest — invalid from day one) and voidable marriages (fraud, duress, incapacity, underage — valid until a court annuls them).
- Annulment has no waiting period in most states, but you must prove specific legal defects at a court hearing — “irreconcilable differences” is not enough.
- The IRS treats an annulled marriage as if it never happened — IRS Publication 504 requires amended returns for every open tax year affected, changing filing status from married to single retroactively.
- Under 20 CFR § 404.331, Social Security divorced spouse benefits require a valid marriage of at least 10 years ending in divorce — annulment generally eliminates eligibility because the marriage is treated as never valid.
What Is an Annulment?
An annulment is a court order declaring that a marriage was never legally valid. Unlike a divorce, which ends an existing marriage going forward, an annulment operates retroactively — it treats the marriage as though it never happened.
The legal term courts use varies by state. California calls it a “judgment of nullity.” Illinois and Washington call it a “declaration of invalidity.” Louisiana uses “absolutely null” and “relatively null.” But the core concept is the same everywhere: the marriage had a fundamental defect from the very beginning.
Under the Uniform Marriage and Divorce Act, which shaped family law in most states, the traditional word “annulment” was replaced with “declaration of invalidity” — and the law draws a hard line between marriages that are void (automatically invalid) and marriages that are voidable (valid until a court says otherwise).
That distinction matters more than most people realize.
Void Marriage vs. Voidable Marriage: The Critical Difference
This is where annulment law gets technical — and where it matters most.
A void marriage is invalid from the moment it happened. It was never legal. The most common examples are bigamy (one spouse was already married) and incest. In most states, a void marriage doesn’t technically require a court order to be considered invalid — but getting a formal declaration is still a good idea, because government agencies, banks, and insurance companies want documentation.
A voidable marriage, on the other hand, is treated as valid until a court officially annuls it. Only the affected spouse can typically challenge it. Fraud, duress, mental incapacity, and underage marriage without consent are the most common voidable grounds.
Here’s why this matters beyond the courtroom: when a second marriage happens before the first is resolved, the void vs. voidable distinction determines whether that second marriage is valid. If the first marriage was void, the annulment relates back and the second marriage stands. If the first marriage was merely voidable, the annulment doesn’t automatically fix the second marriage.
The Cornell Law Institute defines annulment as a procedure that “voids a marriage and declares it null from its inception” — and that retroactive effect is what separates it from every other way a marriage can end.
What Are the Grounds for Annulment?
You can’t get an annulment just because the marriage was short or because things didn’t work out. Courts require specific legal grounds — defects that existed at the time of the marriage ceremony. This is one of the biggest misconceptions people have, and it trips up a lot of folks who assume a quick marriage means a quick annulment.
Grounds that typically make a marriage void (invalid from day one):
Bigamy — one spouse was already legally married. Incest — the parties are closely related by blood. These are recognized in virtually every state.
Grounds that typically make a marriage voidable (valid until annulled):
Fraud or misrepresentation going to the essentials of the marriage. Duress or coercion — one party was forced into the ceremony. Mental incapacity or being under the influence of drugs or alcohol to the point of being unable to consent. Underage marriage without required parental or judicial consent. Physical incapacity to consummate the marriage, unknown to the other party.
Say you married someone who told you they wanted children, and after the wedding you discovered they’d had a permanent sterilization procedure and never disclosed it. In many states, that kind of fraud — going to the “essentials of marriage” — can be grounds for annulment. A spouse who lied about their income? Probably not. Courts look at whether the fraud goes to the core of what marriage means, not just whether someone was dishonest.
Texas has some unusual grounds worth knowing about. Under Texas Family Code Chapter 6, a marriage can be annulled if it took place within 72 hours of the marriage license being issued (with a 30-day filing window) or if one spouse concealed a recent divorce that happened less than 30 days before the wedding.
How to Get a Marriage Annulled
The process looks similar to filing for divorce, but there are key differences — especially around burden of proof and court appearances.
Step 1: Determine grounds. Unlike no-fault divorce, where you just state “irreconcilable differences,” annulment requires proving a specific legal defect existed at the time of the marriage.
Step 2: File a petition. You file in the appropriate court — Superior Court in California, Supreme Court in New York, District Court in Texas. The petition identifies the specific grounds and the facts supporting them.
Step 3: Serve your spouse. Personal service is generally required, just like in a divorce.
Step 4: Prove your case. This is where annulment gets harder than divorce. The petitioner bears the burden of proving the grounds existed. That may require witness testimony, medical records, or documentary evidence. In most states, you’ll need to appear before a judge and explain why the marriage was never valid. The California Courts Self-Help Center makes this clear: “You will have to go in front of a judge to explain why your marriage was never legal.”
Step 5: Court issues decree. If the judge agrees grounds exist, the marriage is declared invalid — typically retroactive to the date of the ceremony.
One practical advantage: annulment often has no waiting period. California’s divorce requires a 6-month waiting period. Its annulment does not. Texas requires a 60-day divorce waiting period. Annulment has none. Residency requirements are also typically looser — in California, you don’t need the standard 6-month residency for annulment that you need for divorce.
Annulment vs. Divorce: How They Differ on Cost, Property, and Support
Filing fees are generally the same — in California, both run about $435–$450 depending on county. In New York, both cost around $335. The real cost difference is in attorney fees and complexity. Annulments often require more evidence and a court hearing, which can drive costs up if the grounds are contested.
Property division is where the consequences diverge sharply. In a divorce, marital property gets divided under the state’s system — community property or equitable distribution. In an annulment, the rules are less predictable.
Some states treat annulment property division the same as divorce. New York’s Domestic Relations Law § 236 explicitly applies equitable distribution to annulment proceedings. Washington applies full community property rules even to invalid marriages. Texas lets courts divide property the same way they would in a divorce.
But in some states, courts do not apply standard divorce property rules unless a putative spouse is found. California is the clearest example. Generally, there’s no property division or spousal support after annulment in California — unless the court determines one spouse qualifies as a “putative spouse.” That’s someone who genuinely believed the marriage was valid. If you qualify, the court treats your property as “quasi-marital property” and divides it the same way it would community property.
Take a situation where one spouse didn’t know the other was already married. The innocent spouse had no idea — they believed the marriage was real for years, built a life, maybe bought a house together. Under California’s putative spouse doctrine, and in states like Illinois, Montana, and Louisiana that codified similar protections, that innocent spouse doesn’t walk away with nothing.
Spousal support follows a similar pattern. In states that apply divorce rules to annulment, alimony is available. In states that don’t, it may only be available through the putative spouse doctrine or through equitable theories like unjust enrichment.
Does Annulment Affect Children, Taxes, and Benefits?
Children. In virtually every state, children born during an annulled marriage are considered legitimate. This is written into statute nearly everywhere — the Uniform Marriage and Divorce Act, Nevada’s NRS 125.410, Illinois’s 750 ILCS 5/303, Montana’s § 40-1-402(4). Custody and child support proceed the same way they would in a divorce, using the best interest of the child standard.
Georgia is the major exception. Under O.C.G.A. § 19-4-1, annulment is prohibited when children are born or are to be born from the marriage. Georgia law requires parties with children to pursue divorce instead of annulment — courts will not grant an annulment when children are born or expected from the marriage.
Taxes. This is where annulment creates a paperwork headache most people don’t see coming. The IRS treats an annulled marriage as though it never existed — retroactively. That means IRS Publication 504 requires you to file amended returns (Form 1040-X) for every open tax year affected by the annulment, changing your filing status from married to single or head of household. A divorce, by contrast, only changes your status going forward from the date the decree is finalized.
Social Security. Under 20 CFR § 404.331, divorced spouse benefits require two things: a valid marriage under state law, and a marriage that lasted at least 10 years before a final divorce. An annulment generally does not satisfy either requirement — the marriage is treated as invalid from the start, so it may not qualify as a “valid” marriage, and annulment is not classified as a “final divorce” under SSA regulations. The SSA’s POMS GN 00305.125 treats void marriages as “legally nonexistent from the beginning.” One narrow exception exists under SSR 69-1, where a state-law annulment that functionally operates as a divorce may preserve benefits — but that’s unusual and depends entirely on how the state characterizes the proceeding.
Immigration. If your green card was based on marriage to a U.S. citizen and that marriage gets annulled, USCIS considers the annulment retroactive — you were never the spouse of a U.S. citizen. Conditional permanent residents who entered the marriage in good faith can seek a waiver, but annulment significantly complicates the process.
Health insurance. Federal COBRA law lists “divorce or legal separation” as qualifying events but does not explicitly mention annulment. The federal employee health benefits system (OPM) explicitly treats annulment and divorce identically, allowing 36 months of continuation coverage. For private-sector employer plans, federal law does not expressly address annulment as a qualifying event. Plan administrators may interpret the termination of spousal coverage differently depending on the plan’s terms.
Civil Annulment vs. Religious Annulment
A religious annulment and a civil annulment are completely separate proceedings with zero legal overlap. A Catholic annulment does not change your legal marital status. A civil annulment does not affect your standing with any religious institution.
The Alaska Court System puts it plainly: “Church annulments are not recognized under state law. This means that a church annulment does not affect anything that is determined by civil law such as child custody, visitation rights, division of property and debt, spousal support, restoring a maiden name, etc.”
People confuse this constantly. If you got a religious annulment but never filed for a civil annulment or divorce, you are still legally married in the eyes of the state — and that affects everything from taxes to remarriage to benefits.
How Annulment Laws Work Differently by State
States handle annulment under different statutes, different terminology, and different rules for property and support. Here’s how it breaks down across representative states.
| State | Key Feature | Property After Annulment |
|---|---|---|
| California | Key FeatureNo residency or waiting period for annulment; putative spouse doctrine codified | Property After AnnulmentNo division unless putative spouse found — then treated as community property |
| Texas | Key FeatureUnique grounds: marriage within 72 hours of license; concealed recent divorce | Property After AnnulmentCourt may divide property same as divorce under Chapter 7 |
| New York | Key FeatureNo court-provided annulment forms; attorney-drafted complaint required | Property After AnnulmentFull equitable distribution applies (DRL § 236) |
| Florida | Key FeatureNo annulment statute — handled entirely through case law and equity | Property After AnnulmentEquity-based division; no statutory framework |
| Illinois | Key FeatureUses “declaration of invalidity”; 90-day limit for fraud claims; putative spouse codified | Property After AnnulmentDepends on retroactivity — if non-retroactive, dissolution rules apply |
| Louisiana | Key FeatureCivil law system: “absolutely null” vs. “relatively null”; strongest putative spouse protections | Property After AnnulmentCommunity property with full putative marriage protections (CC Art. 96) |
| Georgia | Key FeatureAnnulment barred when children exist (O.C.G.A. § 19-4-1) | Property After AnnulmentTreated like total divorce — parties return to pre-marriage status |
| Nevada | Key FeatureNo residency requirement if married in NV; new 2023 summary annulment procedure | Property After AnnulmentCourt determines status of parties (NRS 125.390) |
Nevada passed a new summary annulment procedure in 2023 (AB 227), which created a simplified process when both parties agree — one of the few states to modernize its annulment process in recent years.
Can I Get an Annulment?
A lot of people want an annulment because it sounds cleaner than divorce — no ex-spouse, no divorce on the record. But annulment doesn’t erase the marriage from public records. Court records still exist. The IRS will know. USCIS will know. And the grounds are narrow.
If none of the specific legal grounds apply — if the marriage was valid when it happened and the problems started afterward — then divorce is the path, not annulment. And if the statute of limitations for your ground has expired, or if you continued living with your spouse after discovering the defect (which most states treat as ratification), annulment may no longer be available even if grounds once existed.
Here’s a practical example. Say you discover your spouse committed fraud — they lied about something fundamental before the wedding. In California, you have four years from the date you discovered the fraud to file. In Illinois, it’s 90 days. Miss that window, and the only option left is divorce.
One more thing: your name doesn’t automatically revert to your pre-marriage name after an annulment. In every state examined — California, New York, Texas, Nevada — you need to affirmatively request name restoration as part of the annulment petition. Courts are generally required to grant the request, and you don’t need a separate proceeding. But it won’t happen unless you ask.
FAQ
Does an annulment mean you were never married?
Legally, yes — that’s the entire point. An annulment declares the marriage void from inception, treating it as though it never existed. But court records of the annulment proceeding still exist, and government agencies like the IRS and SSA are aware the marriage took place.
Is an annulment faster than a divorce?
Often, yes — because most states impose no waiting period for annulment, while divorce may require 30 days to 6 months. However, annulments can take longer if the grounds are contested, because you need to prove specific legal defects at a court hearing.
Can you get an annulment after 5 or 10 years of marriage?
It depends on the ground and state. Bigamy and incest can typically be challenged at any time. But fraud, duress, and incapacity have statute-of-limitations windows ranging from 90 days (Illinois) to 5 years (New York for physical incapacity). Marriage length alone is not a factor.
Do both spouses have to agree to an annulment?
No. Like divorce, annulment can proceed even if the other spouse objects. The petitioner must prove the legal grounds to the court’s satisfaction. The other spouse has the right to respond and contest the claim, but their agreement is not required.
What happens if an annulment is denied?
If a judge determines the legal grounds aren’t met, the marriage remains valid. The petitioner can then pursue a divorce instead. An annulment denial does not prevent someone from filing for divorce — these are separate legal actions.
Can you get an annulment for a Las Vegas wedding?
Being married in Las Vegas doesn’t create a special right to annulment. Nevada’s grounds are the same as elsewhere — fraud, lack of consent, bigamy, underage, mental incapacity. However, Nevada has no residency requirement if the marriage took place in the state, which makes filing easier logistically.
What is a putative spouse?
A putative spouse is someone who genuinely believed their marriage was valid when it wasn’t — for example, they didn’t know their partner was already married. States like California, Illinois, Louisiana, and Montana give putative spouses the same property and support rights as legal spouses. It’s a critical protection when an annulment would otherwise leave one party with nothing.
Does an annulment affect Social Security benefits?
It can. Divorced spouse benefits require proof of a valid 10-year marriage that ended in divorce. Since annulment treats the marriage as invalid from the start and is not classified as a divorce, it generally eliminates eligibility for these benefits under SSA regulations.
