Most people assume filing for divorce is straightforward. You decide the marriage is over, you file the paperwork, and the process begins. But New York requires you to state a legal reason for the divorce, and the ground you choose can shape everything from how long the process takes to how contested it becomes.
New York only adopted no-fault divorce in 2010, making it one of the last states in the country to do so. Before that, couples had to prove one of several fault-based grounds just to get in front of a judge. That history still matters, because fault grounds remain available and are sometimes still worth considering. Understanding your options before you file is one of the most practical steps you can take.

What “Grounds” Actually Means in a Divorce Filing
In legal terms, grounds are simply the stated reason the marriage should be dissolved. New York courts require at least one ground to be cited in the initial filing. The ground you choose does not automatically determine how property gets divided or who gets custody, but it does affect the tone, timeline, and cost of the proceedings.
There are two broad categories: no-fault and fault-based. Each has specific requirements, and choosing between them is rarely as simple as picking whichever sounds easier.
No-Fault Divorce in New York: The Most Common Path
What Irretrievable Breakdown Means
The no-fault ground in New York is formally called “irretrievable breakdown of the marriage.” To use it, you must state that the marriage has broken down irreparably for at least six months. You do not need to prove wrongdoing, assign blame, or recount what went wrong. The spouse receiving the divorce papers cannot contest the ground itself either, which removes one major source of early conflict.
This is by far the most commonly used ground in New York today. According to the New York State Unified Court System, the vast majority of divorces filed since 2010 have relied on this ground. It is also the basis for most uncontested divorces, where both parties have already reached or are willing to reach agreement on the core issues.
When No-Fault Makes Sense
For most couples, no-fault is the right choice. It avoids the emotional and financial cost of proving misconduct, keeps court proceedings less adversarial, and generally moves faster. If you and your spouse are prepared to negotiate property division, support, and custody without major disputes, no-fault keeps the focus where it belongs: reaching a fair resolution.
No-fault also protects both parties from having their personal conduct aired in court documents, which becomes especially relevant if there are children involved or if either spouse has professional reputations to consider.
Fault-Based Grounds: When They Still Apply
New York retained its fault grounds after 2010, and they are not just a legal relic. In certain situations, citing a fault ground can have real strategic implications.
The Six Fault Grounds in New York
New York recognises the following fault-based grounds:
- Cruel and inhuman treatment – physical or mental cruelty that makes it unsafe or improper to continue living together
- Abandonment – one spouse physically or constructively abandons the other for at least one year
- Imprisonment – one spouse is imprisoned for three or more consecutive years after the marriage
- Adultery – one spouse engages in sexual relations with a third party; this ground requires corroborating evidence and cannot be proven by the other spouse’s admission alone
- Judgment of separation – the couple has been living apart under a court-issued separation judgment for at least one year
- Separation agreement – the couple has lived apart under a written, notarised separation agreement for at least one year
Each of these comes with specific evidentiary requirements. Cruel and inhuman treatment, for instance, typically requires documented incidents, and courts have held that isolated incidents or verbal disputes generally do not meet the threshold unless they are severe or ongoing.
Does Fault Affect the Outcome?
This is where things get more nuanced. New York courts generally follow equitable distribution principles when dividing marital property, which means fault does not directly determine who gets what. However, in some cases, particularly involving economic fault or dissipation of assets, a spouse’s misconduct can be considered by the court when determining how property should be split.
Fault grounds also matter when it comes to spousal maintenance. Egregious conduct, meaning behaviour so extreme that it would be unjust to award maintenance, can in rare cases affect whether and how much support is ordered.
The more practical impact of citing fault is often the discovery process it triggers. If you allege adultery or cruel treatment, you open the door to depositions, subpoenas, and testimony that can significantly extend the timeline and cost of the case.
Contested Divorce Grounds: Understanding the Real Stakes
When a spouse disputes the grounds cited, or when the underlying issues around custody, assets, or support become highly contested, the case moves into contested divorce territory. This is where the choice of grounds starts to intersect directly with litigation strategy.
Fault grounds in a contested case can become leverage. They can also backfire. Accusing a spouse of misconduct that cannot be adequately proven may weaken your credibility with the court and complicate settlement negotiations. When a case is genuinely headed toward trial, litigation becomes a distinct process with its own procedural demands, including motion practice, discovery, and potentially a full trial on contested issues.
The decision to pursue fault-based grounds in a contested case should never be made without legal guidance. The strategic calculus depends heavily on the specific facts, the evidence available, and what you are ultimately trying to achieve.
Separation Agreements and Legal Separation as a Path to Divorce
One underused option worth understanding is the separation agreement route. If both spouses sign a notarised written separation agreement and live apart for one full year, either spouse can then file for divorce on that ground alone.
This approach is popular for couples who need time to work through financial or custody arrangements before the marriage is formally dissolved, or for those with religious reasons for not rushing the divorce. The agreement itself needs to address all the major issues, and if it is well-drafted, it essentially functions as a pre-negotiated divorce settlement.
It is worth noting that a legal separation (court-issued judgment) is a separate proceeding from a separation agreement. Both can lead to a no-fault divorce after one year, but the legal separation route involves a court process upfront, while the separation agreement is a private document between the parties.
Matching the Ground to Your Situation
Choosing a ground is not purely a legal decision. It is also a practical and emotional one. A few questions worth thinking through before you file:
- Is there genuine misconduct worth documenting? If so, does it rise to the legal threshold for a fault ground, and do you have or can you obtain the evidence needed?
- Are you and your spouse likely to reach agreement? If the answer is yes, no-fault and an uncontested process will almost always be faster and less costly.
- How important is privacy to you? Fault grounds invite more detail into the public record. No-fault keeps the proceedings cleaner.
- What are you trying to accomplish? If the goal is a fair outcome on assets and custody, the ground matters less than the negotiation strategy. If fault genuinely affects financial fairness, it may be worth pursuing.
There is no universally “right” answer. The right ground is the one that fits your facts, your goals, and your willingness to engage in a longer or shorter legal process.
Key Takeaways
- New York requires a stated legal ground for every divorce filing. No-fault (irretrievable breakdown) is the most commonly used and generally the least adversarial option.
- Fault grounds still exist and include cruel treatment, abandonment, adultery, imprisonment, and separation. Each has its own evidentiary requirements.
- Fault rarely changes property division directly in New York, but it can influence spousal support decisions in extreme cases and significantly affects the cost and timeline of proceedings.
- A separation agreement signed by both spouses can serve as a path to divorce after one year of living apart, giving couples time to negotiate before formally filing.
- The choice of ground should align with your goals, your evidence, and your appetite for a longer contested process versus a faster resolution.
Frequently Asked Questions
Can my spouse refuse a divorce if I file on no-fault grounds in New York?
No. Since New York adopted no-fault divorce in 2010, a spouse cannot block the divorce by contesting the irretrievable breakdown ground. They can still contest the financial and custody terms, but they cannot prevent the divorce from proceeding.
Does it help my case to prove my spouse cheated?
Not always. Adultery is a recognised fault ground in New York, but proving it is procedurally demanding and can lengthen the process significantly. In most cases, courts focus on equitable distribution regardless of who was unfaithful. Where it potentially matters is in spousal maintenance, and even then only in exceptional circumstances.
How long does a no-fault divorce take in New York?
An uncontested no-fault divorce, where both parties agree on all terms, can be finalised in as little as three to six months depending on the county and court backlog. Contested cases routinely take one to two years or longer.
What counts as “cruel and inhuman treatment” under New York law?
Courts look for a pattern of behaviour, physical or severe emotional, that makes continued cohabitation unsafe or improper. Isolated arguments or general marital unhappiness typically do not qualify. Documentation, such as medical records, police reports, or witness statements, is usually necessary to support this ground.
Can I change the grounds for divorce after I file?
In some circumstances, yes. An amended petition can be filed, but it needs to meet procedural requirements and the court’s approval. It is much better to make the right choice upfront rather than amend later, which adds cost and delay.
Conclusion
The ground you choose to file on is one of the first and most consequential decisions in any divorce. It sets the tone for everything that follows: whether the case moves quickly or drags on, whether personal conduct becomes a courtroom issue, and in some cases whether financial outcomes are affected.
For most people, no-fault is the practical path. But the exceptions matter, and they are not always obvious without understanding both the law and your specific circumstances. If you are weighing your options, speaking with an experienced New York divorce attorney before you file is genuinely worth the time.
