New York has specific residency requirements and grounds for divorce. You must have been a resident of New York for at least one year before filing, or meet other criteria related to the grounds for divorce.The time it takes to complete paperwork, serve your spouse, and schedule court dates can also affect the overall timeline. If there are disagreements that need to be resolved through negotiation or court hearings, the process can take much longer, potentially 1 to 2 years or more.
