What does it mean that William Mattar, P.C. handles only motor vehicle accident cases?
William Mattar, P.C. only handles one area of the law: injuries from motor vehicle accidents. It describes itself as a dedicated motor vehicle injury firm and also uses the name William Mattar Accident Lawyers. Its Williamsville Principal Office is at 6720 Main St Suite 100, Williamsville, NY 14221, serving New York State.
What rules apply to a motor vehicle accident case in New York?
No-fault benefits. Under Insurance Law § 5103, an owner's policy of liability insurance issued on a motor vehicle to satisfy article six or eight of the Vehicle and Traffic Law must also provide for the payment of first party benefits to persons, other than occupants of another motor vehicle or a motorcycle, for loss arising out of the use or operation of that vehicle in New York.
The 30-day notice. The mandatory personal injury protection endorsement in 11 NYCRR 65-1.1 requires written notice of the accident to be given to the insurer as soon as reasonably practicable, but in no event more than 30 days after the date of the accident. The exception is where the eligible injured person submits written proof providing clear and reasonable justification for the failure to comply with that time limit.
The serious-injury threshold. Insurance Law § 5104(a) provides that in any action by or on behalf of a covered person against another covered person for personal injuries arising out of negligence in the use or operation of a motor vehicle in New York, "there shall be no right of recovery for non-economic loss, except in the case of a serious injury, or for basic economic loss." Section 5102(d) defines "serious injury" through a list that includes death, dismemberment, significant disfigurement and a fracture, among other categories. Part EE of Chapter 58 of the Laws of 2026 deleted the former category for a non-permanent injury that prevents the injured person from performing substantially all of the material acts of the person's usual and customary daily activities for not less than 90 days during the 180 days immediately following the injury.
The 2026 fault rule. Part EE also added CPLR 1411(b). In any action to recover damages for personal injury subject to article 51 of the Insurance Law, the claimant's culpable conduct bars recovery if it is greater than the culpable conduct of the person against whom recovery is sought, or greater than the combined culpable conduct of the persons against whom recovery is sought. According to the New York State Department of Financial Services, these amendments took effect on May 26, 2026, and apply to all actions and proceedings commenced on or after that date.
