General Municipal Law §50-e requires a sworn notice of claim — stating when, where, and how you were hurt — served on the correct public entity within 90 days of the accident. The regime then allows suit no earlier than 30 days after, and no later than one year and 90 days from the accident (GML §50-i). The traps are procedural and unforgiving:
- The correct entity — NYC Transit Authority, MTA Bus, the City itself, and a school district are different respondents; serving the wrong one can be as fatal as serving no one.
- The 50-h hearing — the entity may demand a sworn examination of you before any suit; it is a defense discovery tool and should be prepared for like a deposition.
- Late-notice relief exists but is discretionary — a court may permit a late notice on factors like the entity's actual knowledge; no one should plan on it.
The 90-day rule reaches further than people think: city buses and subways, school buses operated for public districts, public playgrounds and parks, municipal vehicles, and public housing all fall within it.
