Key Takeaways
An annulment is a legal way to end a marriage by treating it as if it never existed. Unlike a divorce, which ends a legal marriage, an annulment results in a judicial ruling that the union was invalid from the very start. In New York, you must prove specific legal reasons to have a marriage annulled. At Hartin Divorce & Family Law, we help clients navigate this complex legal process to protect their rights and change their marital status.
Under New York Domestic Relations Law (DRL) § 140, the court can grant an annulment based on several factors, such as fraud or mental incapacity. Whether you live in New York City or out on Long Island, understanding how these marriage laws work is the first step toward moving forward with your life.
In New York, not all marriages are the same in the eyes of the law. Before you can have a marriage annulled, you must understand if your union is void or voidable. This distinction is the foundation of your entire case and dictates how the court proceedings will move forward.
An invalid marriage is one that was never legal from the moment it began. The law says it is invalid even if no one goes to court to say so. It is as if the wedding ceremony never happened in the eyes of the state. Under DRL § 5 and DRL § 6, these include:
In these cases, the marriage is dead on arrival. You do not technically need a judge to tell you it is over, but most people get a judicial ruling anyway. This is important to clear up your marital status for things like taxes, social security, and future marriage licenses.
A voidable marriage is a bit different and more common in family courts. It is considered a legal marriage until one person asks the court to cancel it. Under DRL § 7, these marriages remain active and legal unless a judge grants an annulment.
The biggest difference here is that if both people decide to stay together even after they find out about the problem, the marriage might remain valid forever. For example, if you find out your spouse lied to you, but you keep living with them as a married couple, a judge might say you ratified the marriage and refuse to annul it later.
Knowing which category you fall into changes your legal proceedings and the type of evidence you need. For a void marriage, you are simply proving a fact that existed at the start, like a birth certificate or a prior marriage license. For a voidable marriage, the case is more about your intent and what happened behind closed doors. You are often proving that you were tricked or that your spouse lacks the physical or mental capacity to truly be a partner. Our legal counsel helps you decide which path fits your story so you don't waste time in the Supreme Court.
In New York, you cannot get an annulment just because you and your spouse don't get along anymore. You must have specific legal reasons that fit into one of the categories set by the state. These are called grounds for annulment.
This is a very frequent reason for void marriages. If your spouse was already married in New York City or anywhere else in the world and never got a legal judgment of divorce, your marriage to them is not real. You cannot be married to two people at once. Sometimes this happens by accident because a spouse thought their first marriage was over, but the law doesn't care about the mistake; the second marriage is still invalid.
The legal age to get married in New York is 18. If a person gets married while they are underage without the right permissions, the marriage can be annulled. This is meant to protect young people from making a choice they aren't ready for. However, there is a catch: if the person turns 18 and continues to live with their spouse as a married couple, they may lose the right to seek an annulment. This is seen as accepting the marriage as an adult.
A person must have the mental capacity to understand the meaning of a marriage contract. Marriage is a legal agreement, and you must be of sound mind to sign it.
Fraud is the most popular reason for seeking a civil annulment. This means your spouse lied about something that was vital to the marriage. It has to be a big lie, not a small one. Examples recognized in New York include:
If a spouse has a physical incapacity that prevents sexual intercourse, and this condition cannot be cured, you may seek an annulment. This is often described as a lack of consummation of marriage. The key here is that the person must have had this issue before the wedding, and the other spouse must not have known about it. If you knew about the condition before the ceremony, you cannot use it as a reason for an annulment later.
The legal process for an annulment is very similar to the divorce process, but the burden of proof is higher. All annulments must be handled in the Supreme Court.
Before you can file, you must show that you belong in a New York court. Generally, at least one spouse must have lived in Long Island, New York City, or another part of the state for at least one full year without leaving. This ensures that the state can change your marital status.
Your family law attorney starts the case by filing a Summons and Complaint. This is a formal document that states exactly which grounds for annulment you are using. It asks the judge to issue a ruling canceling the marriage. Unlike a no-fault divorce, you must be very specific about what went wrong and who is at fault.
The law requires that you officially hand the papers to your spouse. This is called service of process. It is a vital step because it gives the other person a chance to tell their side of the story. If you cannot find your spouse, there are other ways to serve them, but it makes the legal process much longer.
This is the most important part of the case. Because you have to prove a specific reason, like fraud or mental incapacity, you need facts. We help you collect:
Most annulments require a trial or a hearing before a judge. You usually cannot get an annulment just by signing papers in the mail. You must stand in front of the court and provide testimony. The judge will listen to the evidence and then issue a judicial ruling. If you win, the judge signs a paper that makes you legally single.


Many people wonder what happens to their lives once the marriage is erased. The law has rules to make sure things stay fair for everyone involved.
One of the biggest worries is the children. In New York, children born during a later annulled marriage are still considered legitimate. This means they have all the same legal rights as any other child. The family courts will still step in to decide on child custody, child support, and custody arrangements. The annulment of the marriage does not annul your responsibilities as a parent.
Even if the marriage never existed, you likely bought things together. New York’s Equitable Distribution rules still apply here. The judge will look at the house, cars, and bank accounts you shared and divide them fairly among you. The court handles the money just like it would in a divorce process.
Can you get spousal support after an annulment? The answer is yes, but it is not as common as it is in a divorce. Because annulments often happen in shorter marriages, there is less time for one spouse to become financially dependent on the other. However, a judge still has the power to order maintenance payments if it is fair.
If a marriage is annulled because of fraud related to a green card, it can have a devastating impact on a person's immigration status. The government may view the entire relationship as a lie to get immigration benefits. This can lead to deportation or being banned from the country.
It is very important to know that a civil annulment and a religious annulment are two different things.
Getting an annulment is much harder than getting a divorce. In a divorce, you can just say you don't get along. In an annulment, you have to win by proving the other person did something wrong or that the marriage was never legal.
The rules found in the DRL and the CPLR (Civil Practice Law and Rules) are very technical. If you use the wrong words in your complaint, the judge can dismiss your case. A family law attorney knows how to speak the court's language to make sure your case stays on track.
Proving something like intent to defraud is difficult. We help you build a strategy to show the court exactly when the lie happened and why it matters. Whether it involves finding medical records or proving mental incapacity, we do the heavy lifting to find the proof.
Even if you want the marriage gone, you still need to protect your future. We make sure you get a fair share of the property and that your child custody and child support plans are solid. We represent your best interests so you can focus on your emotional healing.
A divorce ends a valid marriage. An annulment is a judicial ruling that states a legal marriage never existed in the first place because it was flawed from the start.
The length of the marriage doesn't matter for an annulment. You must have one of the legal grounds for annulment, such as fraud, bigamy, or mental capacity issues.
Fraud is the most common reason. This usually involves lies about children, a secret criminal past, or marrying only for immigration status or benefits.
Yes. Unlike many divorces, an annulment usually requires a hearing in the Supreme Court, where you must present evidence and testimony to a judge.
Your children remain legitimate under New York law. You will still work with family courts to set up child custody, child support, and visitation.
No. A religious annulment only affects your standing in your church. You still need a civil annulment or a divorce to be legally single in the eyes of the state.


Choosing the right way to end a marriage is a big decision. An annulment can give you the peace of mind that a bad marriage has been wiped away, but it requires a lot of proof and hard work in court. You need a team that understands the local rules in Long Island and New York City.
