The instinct after a defective product injures someone is almost always to clean up, throw the broken thing away, or return it to the store for a refund. That instinct is exactly what can quietly cost you your case months later, sometimes before you’ve even called an attorney.
What you do in the first hours and days after a product hurts you often matters as much as what actually happened.
New York courts take this seriously enough that losing or destroying evidence, even by accident, can lead to real legal consequences of its own, separate from whatever the manufacturer did wrong.
Prior results do not guarantee a similar outcome.
Why New York Courts Punish Losing Evidence, Even by Accident
Once litigation is reasonably foreseeable, meaning once you suspect a product caused serious harm, you have a legal duty to preserve evidence, and that duty exists well before anyone actually files a lawsuit.
If you throw away the product, or let someone repair it, after that point, courts apply a specific three-part test to decide whether sanctions are warranted: whether you had control over the evidence and a duty to preserve it, whether it was destroyed with a culpable state of mind, and whether the destroyed evidence was actually relevant to the case.
The part people don’t expect is that “culpable state of mind” doesn’t require intent. Ordinary negligence, tossing something during a routine cleanup, counts too, though the burden shifts depending on which it was: if the destruction was willful, relevance is presumed against you; if it was merely negligent, the other side has to prove the missing evidence actually mattered.
New York’s disclosure statute, CPLR 3126, gives courts broad authority here, resolving disputed issues against the responsible party, barring specific evidence, striking pleadings, or entering default judgment. In practice, courts keep the punishment proportional to the harm.
The harshest outcome, dismissal or striking pleadings outright, is reserved for willful, bad-faith destruction and is genuinely rare. Far more common is an adverse inference instruction, where the jury is told they may assume the missing evidence would have hurt your case.
That’s a real cost even when it’s not fatal to your claim, which is exactly why prevention matters more than any argument you could make afterward.
What to Do With the Product Itself
The defective item is almost always the single most important piece of evidence you have. Don’t clean it, repair it, replace broken parts, or reset it if it’s electronic.
Don’t return it to the store or hand it over to the manufacturer if they ask to inspect it, once they have physical possession, you lose control over what happens to it next, and an attorney can set conditions for any inspection before that happens through a written preservation agreement addressing chain of custody.
Stop using it the moment it becomes unsafe and store it somewhere secure and undisturbed. For large items, a vehicle, machinery, an e-bike battery, arrange secure storage and keep a written chain-of-custody log noting who handled it, when, and where it’s been kept.
Log Entry | What to Record |
|---|---|
The item | Description, model/serial/lot number, condition, photographs |
Date and time | When and where it was collected or stored |
Handlers | Every person who received, moved, inspected, or photographed it |
Storage | Exact location and condition |
Changes | Any repair, cleaning, movement, or deterioration since collection |
The one exception is genuine ongoing danger, a smoldering appliance, a leaking container. Safety comes first in that situation.
Photograph it extensively from every angle before anyone moves or disposes of it, and document who removed it, when, and why.
If it’s too dangerous to keep, don’t assume that means you can simply discard it either. Contact an attorney or investigator before disposal if at all possible.
What Else You Should Save
Beyond the product itself, a handful of other categories of evidence tend to make or break these cases, and they’re the things people discard without realizing their value.
Category | Why It Matters | What to Save |
|---|---|---|
Packaging and labels | Model numbers, lot codes, and manufacturing dates tie your injury to a specific production batch and any related recall | Boxes, warning labels, instruction manuals, warranty cards |
Purchase records | Establishes ownership, purchase date, and the retailer, even if someone else bought it | Receipts, order confirmations, bank or credit card statements |
Proves the injury happened and how severe it was; delayed care creates a gap the manufacturer can exploit | ER records, imaging, lab results, prescriptions, PT notes | |
Photos and video | Captures conditions that change quickly, healing injuries, a cleaned-up scene, a moved product | Multiple angles of the product and injury, taken as early as possible, unedited |
Witnesses | Can counter claims that you misused or modified the product | Full contact info collected while memories are fresh |
Communications | Manufacturer emails or recall notices can show they knew about the problem | Complaint emails, chat logs, recall notices, incident reports |
A few situations call for extra specifics. With a vehicle, keep the vehicle itself where possible, along with the VIN, event data recorder information if available, and don’t authorize salvage or major repair without considering whether an inspection is needed first.
With an implanted medical device, ask the facility in writing to preserve it if it’s removed during a revision or explant procedure, and don’t stop using or remove a still-implanted device without medical guidance.
In a workplace injury, equipment inspection and maintenance records, training records, and safety data sheets matter alongside witness accounts from coworkers, and a workers’ compensation claim doesn’t automatically prevent a separate claim against the product’s manufacturer.
The Recall Rule Most People Get Backwards
Here’s a nuance worth knowing specifically: if a manufacturer redesigns a product, revises a warning, or issues a recall after your injury, that later action generally can’t be used at trial simply to prove the manufacturer was negligent.
New York’s evidence rules restrict this kind of “subsequent remedial measure” from being offered for that purpose, with narrow exceptions, including using a later design change specifically to help prove a manufacturing defect claim rather than negligence generally.
In practice, this means a recall issued the week after your injury is still useful evidence to preserve, but it doesn’t work the way most people assume; it’s not a simple admission of fault you can wave at a jury, and how it can actually be used depends on the specific legal theory your case is built on.
Getting the Manufacturer to Preserve Their Own Records
Preservation isn’t only about what you hold onto. A written evidence-preservation letter sent early to the manufacturer, retailer, insurer, or property owner, identifying the incident and the categories of evidence you expect them to retain, can matter just as much as protecting the physical product yourself.
It puts them on formal notice, which matters if they later claim they didn’t know litigation was foreseeable. This is worth having an attorney draft rather than doing it yourself, since it needs to be tailored to the specific claim and recipient to actually hold up.
Summing It Up
The pattern in these cases is consistent: the biggest threats to a strong claim usually aren’t things the manufacturer does, they’re things that happen in the first few days after the injury, before anyone thought to call an attorney.
Keep the product exactly as it was, don’t clean or repair anything, save the packaging and purchase records you’d normally throw away, document your injuries as they happen and as they heal, and get contact information from anyone who saw what happened. If something is already gone, say so early rather than late.

Frequently Asked Questions
I already threw away the product that injured me. Is my case over?
Not necessarily. Photos, witness statements, medical records, and expert analysis of similar products can sometimes fill that gap. Tell your attorney exactly what happened and when, since hiding a gap in the evidence is far more damaging than disclosing it.
Does it matter if I destroyed evidence by accident rather than on purpose?
Yes, but not in the way people expect. New York courts can sanction negligent destruction, not just intentional destruction, though the other side generally has to prove the missing evidence actually mattered if it wasn’t willful.
If the manufacturer issued a recall after my injury, doesn’t that prove they were negligent?
Not automatically. New York’s evidence rules generally restrict using a later recall or redesign to prove negligence, though there are narrow exceptions depending on your specific legal theory. It’s still important evidence to preserve, just not a simple admission of fault.
How soon after an injury should I start preserving evidence?
Immediately. The legal duty to preserve evidence begins once litigation is reasonably foreseeable, which is well before you file anything or even hire an attorney, essentially as soon as you suspect a product caused serious harm.
How much does a product liability lawyer cost in New York?
Porter Law Group works on a contingency fee basis. There’s no upfront cost, and no fee unless we recover compensation on your behalf.
