To file for divorce in New York, residency requirements must be met. Generally, one spouse must have lived continuously in New York for at least one year before filing, unless the marriage occurred in New York, in which case six months' residency suffices. Additionally, if neither spouse resides in New York, but the grounds for divorce arose in the state, residency for at least one year before filing is necessary. Meeting these requirements ensures that New York courts have jurisdiction over the divorce proceedings and allows for the legal dissolution of the marriage within the state's legal framework.
