New York Domestic Relations Law (DRL) §170 sets forth the legal grounds upon which a court may grant a judgment of divorce. One of the fault-based statutory grounds is DRL §170(4), which permits a divorce when a spouse has been imprisoned for an extended period. In contrast, DRL §170(7) provides New York's no-fault ground for divorce based on the irretrievable breakdown of the marriage. Although both provisions authorize the dissolution of a marriage, they differ in their legal requirements, the evidence necessary to establish the claim, and their practical use in modern divorce proceedings.
DRL §170(4) provides that a divorce may be granted when either spouse has been confined in prison for a period of three or more consecutive years after the marriage was solemnized. The imprisonment must occur after the parties were legally married, and the three-year period must be continuous. The purpose of this provision is to recognize that prolonged incarceration may fundamentally disrupt the marital relationship and make it unreasonable to expect the non-incarcerated spouse to remain legally married. To obtain a divorce under this ground, the spouse seeking the divorce must present evidence establishing the fact and duration of the incarceration, typically through official correctional records or other admissible documentation.
A spouse may choose to file under DRL §170(4) when the statutory requirements are clearly satisfied and incarceration is the principal reason the marriage has ended. Because imprisonment is an objective fact that can usually be established through official records, disputes over whether the ground exists are often less extensive than in other fault-based actions. Nevertheless, filing under this provision still requires proof of the statutory elements and may involve litigation if other aspects of the divorce, such as equitable distribution, maintenance, child custody, visitation, or child support, remain contested. Additionally, relying on a fault-based ground may unnecessarily complicate the proceedings when the parties simply wish to end the marriage.
For these reasons, many spouses instead elect to file under DRL §170(7), New York's no-fault divorce statute. Under this provision, a spouse need only state under oath that the marriage has broken down irretrievably for at least six months. The court is not required to determine whether either spouse committed misconduct or whether any specific fault-based ground exists. Once all ancillary issues, including property division, financial support, and matters involving children, have been resolved through agreement or court order, the court may grant the divorce.
Filing under DRL §170(7) offers significant practical advantages. Because there is no need to prove fault or establish statutory misconduct, the divorce process is generally more efficient, less expensive, and less adversarial. The parties can devote their attention to resolving important financial and parenting matters rather than litigating the reasons for the marital breakdown. This streamlined approach often promotes settlement, conserves judicial resources, and reduces emotional strain on both spouses and any children affected by the divorce.
In conclusion, DRL §170(4) remains an important statutory ground for divorce when one spouse has been imprisoned for three or more consecutive years after the marriage. It provides a legal remedy in circumstances where long-term incarceration has made continuation of the marital relationship impractical. However, because DRL §170(7) allows spouses to obtain a divorce without proving fault, it has become the preferred ground in most cases. For individuals seeking an efficient and less contentious dissolution of an irretrievably broken marriage, filing under DRL §170(7) is generally the most practical and effective choice under New York law.
