When a marriage is annulled, a court has declared that it was never legally valid in the first place. An annulment does not end a marriage the way divorce does; it erases it, treating the union as though it never happened. After the decree, your legal status is “single” or “unmarried,” not “divorced.” That distinction carries real weight for property, support, benefits, and government records.
Annulled Versus Divorced
Divorce and annulment both close out a marital relationship, but they start from opposite premises. A divorce says the marriage was real and is now over. An annulment says the marriage had a legal defect so fundamental that the law should never have recognized it.
The practical consequences follow from that premise. After a divorce, you are a formerly married person with potential obligations like alimony and an equitable share of marital property. After an annulment, neither party is generally entitled to spousal support or property division, because in the law’s eyes there was no marriage to divide. Divorce is available to anyone in a valid marriage, and every state allows you to file without proving your spouse did anything wrong. Annulment requires you to prove specific grounds with evidence and testimony. And the paperwork trail differs for life: divorce changes your status to “divorced,” while annulment changes it to “single,” a difference that shows up on legal forms, background checks, and government records.
Void and Voidable Marriages
Annulment grounds split into two categories, and the difference matters.
A void marriage is one the law considers invalid from the moment it took place, whether or not anyone challenges it. The two most common examples are bigamy, where one spouse was already married to someone else, and marriages between close blood relatives. These unions are illegal under every state’s domestic relations statutes, and a court will declare them void once the facts come out. There is generally no filing deadline, because the marriage was never valid to begin with.
A voidable marriage looks valid on the surface but has a hidden defect. It stays legally recognized unless the injured party actively goes to court to set it aside. If neither spouse ever raises the issue, the marriage stands. Fraud, duress, lack of mental capacity, intoxication during the ceremony, and being underage without proper consent are typical voidable grounds.
Grounds Courts Will Accept
Grounds vary by state, but a core set appears nearly everywhere:
- Bigamy: one spouse was already legally married when the ceremony took place, making the second marriage void automatically.
- Incest: the spouses are close blood relatives, which renders the marriage void from the start.
- Fraud: one spouse lied about or concealed something fundamental to the marriage.
- Duress: one spouse was coerced into the marriage through threats or force and never truly consented.
- Mental incapacity: one spouse lacked the cognitive ability to understand marriage at the time of the ceremony, whether because of a mental condition or severe intoxication.
- Underage: one spouse was below the legal age for marriage and did not have required parental or court approval.
What Counts as Fraud
Fraud is the ground people ask about most, and courts scrutinize it closely. Not every lie qualifies. The misrepresentation generally has to involve something central to the marriage itself: the ability or willingness to have children, sexual capacity, a hidden sexually transmitted disease, or concealment of a prior marriage. Lying about wealth, temperament, career success, or personal habits almost never qualifies, even when the truth would have changed your mind about the wedding.
You also have to show that you genuinely relied on the false information when deciding to marry. And even when fraud is clear, courts weigh other factors. A long marriage is harder to annul than a short one. A marriage that produced children faces higher scrutiny than one that did not. The longer you stayed after discovering the truth, the weaker your case becomes, because a court may read that as accepting the marriage despite the deception.
Duress and Capacity
Duress means more than social pressure to go through with a wedding. Courts look for genuine threats, whether physical, financial, or emotional, serious enough that a reasonable person would have felt they had no real choice. The coercion has to have existed at the time of the ceremony. If you freely chose to marry and only later felt trapped, that is a reason for divorce, not annulment.
Mental incapacity works similarly. The question is whether you understood the nature of the marriage contract at the moment you said your vows. Severe intoxication or drug impairment can qualify, but you would typically need to show you were so impaired you did not grasp what was happening. Having second thoughts or being tipsy at the reception does not meet the bar.
Money, Property, and Support After an Annulment
Because annulment treats the marriage as if it never existed, the default financial outcome is that each party leaves with whatever they brought in. There is generally no right to spousal support or equitable division of property. That is a sharp contrast to divorce, where courts divide marital assets and may order alimony.
This default can produce harsh results, particularly when one spouse gave up a career or supported the household for years before the annulment. The putative spouse doctrine exists to soften that outcome. In states that recognize it, a spouse who genuinely believed in good faith that the marriage was valid can receive the same property and support rights as a spouse in a divorce. The doctrine is designed to protect someone who was deceived, such as a person who did not know their partner was already married.
Not every state recognizes putative spouse status, and the burden is on you to prove you had no reason to suspect the marriage was invalid. The spouse who knew about the defect generally cannot claim it. If both parties knew the marriage was not legal from the start, neither qualifies.
What Happens to Children
Children born during a marriage that is later annulled are still considered legitimate in every state. Annulment does not rewrite biology or erase the fact that a legal relationship existed between the parents at the time of birth. Custody, child support, and visitation are handled the same way they would be in a divorce. A judge enters custody and support orders during annulment proceedings, and both parents keep their rights and responsibilities toward their children regardless of whether the marriage is declared void or voidable.
Immigration, Insurance, and Social Security
An annulment can reach well beyond family court. If you obtained immigration benefits through a marriage that is later annulled, the annulment retroactively eliminates the basis for those benefits. U.S. Citizenship and Immigration Services treats an annulled marriage as one that never existed, which means someone who naturalized as the spouse of a U.S. citizen could lose eligibility if the marriage is annulled before or after the naturalization application.
Health insurance changes immediately. A spouse covered under the other’s employer-sponsored plan typically loses coverage when the annulment is finalized, just as they would in a divorce. Social Security spousal benefits depend on having been in a valid marriage for at least ten years. If the marriage is annulled, that clock effectively resets to zero because the marriage is deemed never to have existed.
Deadlines for Filing
Most states impose deadlines for seeking an annulment, and the deadline depends on the ground. Void marriages like bigamy and incest are generally exempt from time limits, since they were never legal to begin with. Voidable grounds are a different story.
Fraud-based annulments commonly must be filed within a set period after discovering the deception, often ranging from 90 days to a few years depending on the state. Underage marriages typically must be challenged before the minor spouse reaches adulthood. Incapacity-based claims usually need to be brought soon after the affected spouse regains capacity or sobriety. If you miss the window, divorce becomes your only option.
Courts also watch for continued cohabitation after you learn about the defect. If you discover your spouse committed fraud but stay in the marriage for another two years, a judge may decide you ratified the marriage through your actions, even if you are technically within the statute of limitations.
Religious Annulment Is Not the Same Thing
A religious annulment, most commonly associated with the Catholic Church, is a declaration by a religious tribunal that no valid sacramental marriage existed. It has no legal effect. It does not change your marital status in government records, affect your property rights, or end your legal obligations. If you want both a civil and a religious annulment, you have to pursue each separately, and the grounds are not interchangeable. A religious annulment might be granted on grounds a civil court would reject, and a civil annulment for bigamy does not automatically produce a religious one.
