Plain-English Summary

Section 3043 takes the general demand authority in section 3041 and applies it to personal injury cases, listing the categories of detail a defendant may require: the date and approximate time of the occurrence, its approximate location, a general statement of the acts or omissions said to be negligent, whether the case relies on actual or constructive notice of a dangerous condition (and if actual, when and to whom notice was given), the plaintiff's injuries and which of them are claimed to be permanent, and -- in a motor vehicle case -- whether the plaintiff meets the 'serious injury' or economic-loss thresholds under the Insurance Law. It also covers how long the plaintiff was confined to bed or house, how long the plaintiff missed work, and the specific dollar totals claimed for medical bills, lost earnings (with the employer's name and address), hospital expenses, and nursing services.

Because injuries and expenses keep accumulating after a bill of particulars is first served, subdivision (b) lets a plaintiff serve a supplemental bill covering continuing special damages and disabilities without asking the court's permission, as long as it's served at least thirty days before trial. That supplemental bill can't smuggle in a new cause of action or a new injury -- it can only update the numbers on damages already claimed -- and it entitles the defendant, on seven days' notice, to reopen discovery, but only on those continuing items.

Subdivision (c) reminds the court that the list in subdivision (a) isn't a ceiling or a floor: a court can deny any of the specified particulars in a case where they don't fit, or require particulars beyond the list where the case calls for it.

Frequently Asked Questions

What can a defendant ask for in a personal injury bill of particulars?

Under CPLR 3043, a defendant can ask for the date, time, and place of the accident, the negligence claimed, notice of any dangerous condition, the plaintiff's injuries, time lost from bed, house, and work, and itemized special damages such as medical bills and lost earnings.

Do I need the court's permission to update my bill of particulars for ongoing medical bills?

No. Subdivision (b) lets a plaintiff serve a supplemental bill of particulars for continuing special damages and disabilities without leave of court, as long as it's served at least thirty days before trial.

What is a 'serious injury' bill of particulars in a New York car accident case?

It's the item in CPLR 3043(a)(6) requiring a plaintiff in a motor vehicle negligence case to specify how the injuries meet the serious-injury or economic-loss definitions in the Insurance Law.

Can a court require more than the items listed in CPLR 3043?

Yes, subdivision (c) lets the court grant other, further, or different particulars in a proper case, and just as easily deny any of the listed ones where they don't apply.

Can a supplemental bill of particulars add a new injury or claim?

No. Subdivision (b) is limited to updating continuing special damages and disabilities -- it can't be used to allege a new cause of action or a new injury.

How much notice must the defendant give to reopen discovery after a supplemental bill of particulars is served?

Seven days -- the defendant is entitled, on seven days' notice, to newly exercise discovery rights, but only concerning the continuing special damages and disabilities the supplemental bill describes.
