What Marriage Annulment Is and How It Differs From Divorce

Marriage annulment and divorce are two different legal ways to end a marriage, but they work in fundamentally different ways. Understanding the distinction is important because the process, timeline, and legal consequences differ significantly.

A divorce is a court order that dissolves a valid marriage. When a marriage is valid, it means the two people were legally married according to all the requirements of their state. A divorce recognizes that the marriage existed and formally ends it. The court then addresses property division, custody arrangements, and support obligations based on the years the couple spent together.

An annulment, by contrast, is a court declaration that the marriage was never valid in the first place. Rather than ending an existing marriage, an annulment treats the marriage as though it never legally occurred. This is a critical distinction. When a court grants an annulment, the legal position is that no valid marriage ever existed between the two people, even though they may have lived together and had children.

The grounds for annulment are also different from grounds for divorce. Most states allow divorce for "no-fault" reasons, meaning neither spouse has to prove the other did anything wrong—they can simply cite irreconcilable differences or the breakdown of the marriage. Annulment, however, requires specific grounds that show why the marriage was never valid to begin with. These grounds vary by state but typically include issues like lack of consent, fraud, bigamy, impotence, or being underage without parental consent at the time of marriage.

In many states, annulment must be pursued relatively quickly after marriage. Some states impose time limits—called statutes of limitation—that range from several months to a few years. For example, in California, grounds related to fraud must generally be discovered and pursued within four years of the marriage. This time restriction is another key difference from divorce, which can typically be filed at any point after marriage.

Practical Takeaway: Before proceeding with either option, understand that annulment and divorce have different legal meanings, different grounds, and different timelines. Consulting with a family law attorney in your state can clarify which option applies to your situation and what the specific rules are in your jurisdiction.

Grounds for Annulment That May Be Recognized in Your State

Each state sets its own rules about which grounds are acceptable for annulment. While there is no national standard, most states recognize certain common grounds. Learning what these grounds are can help you determine whether annulment might be possible in your circumstances.

Lack of Consent is one of the most widely recognized grounds. This means one or both parties did not truly agree to the marriage. Examples include situations where one person was forced into marriage against their will, was threatened, or was coerced by family members or others. Lack of consent must be genuine—simply having regret or changing your mind after the wedding is not the same as lacking consent at the time.

Fraud is another common ground. This occurs when one spouse deceived the other about something fundamental to the marriage. States vary in what they consider fundamental fraud. Examples might include one spouse lying about their ability to have children when having children was central to why the other person married them, or hiding a serious criminal history, or misrepresenting their financial situation, religious beliefs, or intent to have children. Minor deceptions typically do not count as grounds for annulment.

Bigamy is recognized in all states as grounds for annulment. This means one spouse was already legally married to someone else at the time of the marriage in question. The marriage is automatically void because it violates the legal requirement that both parties be unmarried.

Underage Marriage is recognized in most states. If one spouse was below the legal age for marriage in that state (typically 16 or 18, though some states allow marriage at younger ages with parental consent), and the underage spouse's parents or guardians did not consent, the marriage may be annullable. However, if the underage spouse reaches the legal age and continues living with their spouse, some states will not allow annulment.

Mental Incapacity is recognized in many states. This means one spouse was not mentally capable of understanding what marriage means or the duties it creates. This might apply in situations involving severe mental illness, intellectual disability, or being under the influence of drugs or alcohol at the time of marriage to a degree that prevented understanding.

Impotence is a ground recognized in some states. This specifically refers to the inability to consummate the marriage and must typically be permanent. This is different from infertility and applies only in certain states.

Practical Takeaway: Review your state's specific laws about which grounds for annulment are recognized. Different states have different definitions and requirements. What counts as fraud in one state may not in another. State bar associations or family law court websites typically provide this information.

The Annulment Process and What to Expect

The process for obtaining an annulment varies somewhat from state to state, but the general framework is similar. Understanding the steps involved can help you know what to expect if you decide to pursue an annulment.

The first step is typically to file a petition for annulment with the court in the county where you live or where the marriage took place, depending on your state's rules. This petition is a formal legal document that states the grounds for annulment you are relying on. You will need to provide specific facts that support your claim. For example, if you are claiming fraud, you need to explain exactly what false statement was made, when it was made, that you relied on it, and how it affected your decision to marry. Vague allegations are not sufficient.

The petition is served on your spouse, meaning they are officially notified of the filing and given a copy. Your spouse then has the opportunity to respond, typically within 20-30 days depending on your state. They may agree with the annulment request, or they may contest it by filing their own response with the court.

If both spouses agree that the grounds for annulment are present, the process is relatively quick. Many courts have simplified procedures for uncontested annulments. In these cases, the court may grant the annulment based on the written documents alone, and you may not need to appear in court. Some courts, however, require at least one appearance before a judge even in uncontested cases.

If your spouse contests the annulment, the case becomes more involved. You may need to provide evidence to support your claims. This could include documents (such as emails, letters, or financial records), witness testimony, or your own testimony in court. For example, if you claim fraud because your spouse lied about their ability to have children, you might provide medical records, testimony from your spouse's friends about what they said before marriage, or text messages where your spouse discussed their intentions.

The timeline for annulment can vary significantly. Uncontested annulments may be finalized in weeks or a few months. Contested annulments can take many months or longer, depending on how busy the court is and how much evidence needs to be gathered and presented. During this time, issues like property division, custody of children, and spousal support may also need to be addressed by the court.

Court fees for filing a petition for annulment vary by county and state, typically ranging from $200 to $500. If you cannot afford these fees, you may petition the court for a fee waiver. Additional costs may include attorney fees if you hire a lawyer to represent you, costs for obtaining documents or records, and costs for expert witnesses if needed.

Practical Takeaway: Before filing, gather all documents that support your grounds for annulment and understand your state's specific rules about filing location, response timeframes, and required evidence. Having organized documentation from the start can make the process clearer.

How Annulment Affects Property, Custody, and Support

One common misconception about annulment is that because the marriage is declared never to have been valid, property division and custody arrangements do not need to be addressed. This is not accurate in most states. Even when a marriage is annulled, the court typically must still resolve financial and custodial issues that arose during the period the couple lived together.

Property Division in annulment cases varies by state. Some states treat annulled marriages similarly to divorces for property purposes, meaning property acquired during the
