Like Nassau, Suffolk County has no single county marriage license office — licenses are issued by the individual town clerks that make up the county, such as Brookhaven and Islip, the two largest.
| License fee | $40, the standard fee for licenses issued outside New York City. |
|---|---|
| Waiting period | 24 hours after issuance (New York statewide rule), waivable only with a judicial waiver. |
| Documents / ID required | Proof of age and photo identification for both applicants. |
| License validity | 60 days, beginning the day after issuance (New York statewide rule). |
| Where & how to apply | Apply in person, together, at the Town Clerk’s office covering your address — for example, Brookhaven Town Clerk (1 Independence Hill, Farmingville) or Islip Town Clerk (655 Main Street, Islip). |
| Office hours | Varies by town; Brookhaven offers extended hours Monday evenings 5:00–7:00 p.m. in addition to standard 9:00 a.m.–4:30 p.m. weekday hours. |
Special notes
Suffolk County spans ten towns in total — confirm which town clerk covers your specific address before applying.
