Understanding what are the grounds for divorce in NY is essential when you're considering ending your marriage. New York law provides both no-fault and fault-based grounds for divorce, each with specific requirements and implications for your case. As Christina Lana Shine, Esq, I help clients throughout Amherst navigate the divorce process by selecting the most appropriate grounds for their circumstances.

The grounds you choose for divorce can affect how quickly your case proceeds, what issues require proof, and your overall litigation strategy. While many divorces now proceed under no-fault grounds, understanding all available options helps you make informed decisions about your case.
New York recognizes both no-fault and fault-based grounds for divorce. The most commonly used ground is the no-fault option, which requires stating that the marriage has broken down irretrievably for at least six months with no reasonable prospect of reconciliation. This ground doesn't require proving wrongdoing by either spouse and typically results in faster, less contentious divorces.
New York also maintains several fault-based grounds including cruel and inhuman treatment, abandonment for at least one year, imprisonment for three or more consecutive years, adultery, and living separate and apart for at least one year pursuant to a separation agreement or decree. While these fault-based grounds remain available, they require proof of specific conduct and generally make divorce proceedings more complicated, expensive, and time-consuming. Most clients today choose the no-fault ground for its simplicity and efficiency, though fault-based grounds may be appropriate in certain circumstances.
New York adopted no-fault divorce in 2010, providing couples with a simpler path to dissolution without proving wrongdoing by either spouse. When people ask what are the grounds for divorce in NY, the no-fault option has become the most commonly used ground.
The irretrievable breakdown of the marriage for at least six months serves as New York's no-fault ground for divorce. To use this ground, you must simply state that your relationship has broken down irretrievably for a period of at least six months, with no reasonable prospect of reconciliation.
This no-fault approach offers several advantages:
However, choosing no-fault grounds doesn't eliminate disputes over important issues. No-fault divorce still requires addressing:
The no-fault ground addresses only why the marriage is ending, not how these critical matters should be resolved. These issues still require negotiation or court determination regardless of which grounds you select.
While no-fault divorce has become prevalent, New York law still recognizes several fault-based grounds. Understanding what are the grounds for divorce in NY includes knowing these traditional grounds that remain available:
Cruel and inhuman treatment serves as grounds for divorce when one spouse's conduct endangers the physical or mental well-being of the other spouse, making it unsafe or improper to continue living together. This ground covers physical violence, threats of violence, verbal abuse, or other conduct that makes continuing the marriage intolerable.
To establish cruel and inhuman treatment, you must prove specific acts occurred within the five years before filing for divorce. General allegations of incompatibility or unhappiness aren't sufficient. The conduct must rise to a level that endangers your physical or mental health.
Evidence supporting this ground might include:
Abandonment grounds exist in two forms: actual abandonment and constructive abandonment. Actual abandonment occurs when your spouse leaves the marital residence without justification and doesn't return for at least one continuous year. The abandonment must be voluntary and without your consent.
Constructive abandonment involves one spouse refusing sexual relations for at least one year without justification or consent. This ground recognizes that complete withdrawal from the marital relationship can occur even when both spouses continue living in the same home.
To prove abandonment, you must demonstrate:
Simply moving out doesn't automatically constitute abandonment if the departure was by mutual agreement or for legitimate reasons like employment relocation with plans to reunite.
Imprisonment of your spouse serves as grounds for divorce when your spouse was imprisoned for three or more consecutive years after your marriage began. The imprisonment must have occurred after you married, and you must file for divorce either while your spouse remains imprisoned or within five years of their release.
This ground recognizes that long-term imprisonment fundamentally alters the marital relationship and provides a path to divorce for spouses who don't want to remain married to incarcerated individuals.
Adultery remains a fault-based ground for divorce in New York, though it's less commonly used today given the availability of no-fault divorce. Adultery involves voluntary sexual intercourse between a married person and someone other than their spouse during the marriage.
Proving adultery requires:
Direct proof of sexual relations is rarely available, so courts accept circumstantial evidence that demonstrates both opportunity and adulterous disposition. Pursuing divorce based on adultery can make cases more contentious, expensive, and time-consuming than no-fault alternatives. However, some clients feel strongly about establishing their spouse's fault on the record.
New York law allows divorce based on living separate and apart for at least one year under a written separation agreement. This ground requires:
This approach allows couples to formalize their separation arrangements before finalizing divorce, providing time to ensure the agreed-upon terms work practically before converting the separation into divorce.
Similar to the separation agreement ground, you can seek divorce based on living apart for one year under a judicial decree of separation. This ground applies when:
Separation decrees are less common than separation agreements but serve similar purposes in allowing couples to establish separation arrangements before pursuing final divorce.
Before filing for divorce in New York, you must meet residency requirements in addition to establishing grounds. What are the grounds for divorce in NY becomes relevant only after you've satisfied these residency requirements.
You can file for divorce in New York under the following residency scenarios:
Both spouses resident with grounds in New York: Both you and your spouse are New York residents at the time of filing, AND the grounds for divorce occurred in New York—allowing you to file immediately without waiting periods.
These requirements serve important purposes:
Meeting residency requirements is a threshold issue that must be satisfied before the court will consider your divorce petition, regardless of how strong your grounds for divorce may be.
The grounds you select can influence various aspects of your divorce proceedings. Understanding what are the grounds for divorce in NY includes recognizing how this choice affects your case strategy.

No-fault divorces typically proceed faster than fault-based divorces. When you don't need to prove wrongdoing, you eliminate contested hearings about marital misconduct, reduce discovery needs related to fault allegations, and avoid appeals challenging fault findings.
Fault-based divorces require gathering evidence, presenting witness testimony, and potentially defending against your spouse's counter-allegations. This process extends timelines and increases costs.
New York is an equitable distribution state, meaning courts divide marital property fairly though not necessarily equally. The grounds for divorce generally don't affect property division outcomes. Whether you divorce based on irretrievable breakdown or adultery, courts still divide property based on factors like marriage length, income levels, contributions to the marriage, and future earning capacity.
However, fault can indirectly influence property division in limited circumstances. If marital misconduct involved dissipating marital assets—such as spending significant sums on an affair partner—courts may consider this when dividing remaining property.
Spousal support determinations focus primarily on financial factors rather than fault. Courts consider income levels, earning capacity, marriage length, health, and contributions to the marriage when determining support. Fault-based grounds typically don't affect support awards unless the conduct had significant financial implications.
Grounds for divorce don't directly affect child custody determinations. Courts decide custody based on children's best interests, not parental conduct that led to divorce. However, if fault-based grounds involve conduct affecting parenting—such as domestic violence, substance abuse, or behavior endangering children—these factors do influence custody decisions as part of best interests analysis.
No-fault divorce offers greater privacy than fault-based proceedings. Divorce papers alleging irretrievable breakdown don't detail intimate or embarrassing conduct. In contrast, fault-based complaints describe adultery, cruelty, or other sensitive matters that become part of public court records.
For clients concerned about privacy, business reputations, or protecting children from learning details about parental conflict, no-fault grounds provide significant advantages.
Deciding which grounds to use when filing for divorce requires evaluating your specific circumstances, goals, and priorities. Understanding what are the grounds for divorce in NY and how each option affects your case helps you make informed strategic decisions.
Most of my Amherst clients proceed under no-fault grounds given the simplicity, lower cost, faster timeline, and privacy benefits. The irretrievable breakdown ground allows divorce without contentious fault allegations while still addressing all necessary property, support, and custody issues. I help you evaluate which grounds best suit your circumstances and align with your goals for moving forward after your marriage ends.
