If you were hurt in an assault, robbery or shooting on someone else's property, preserving records means keeping the original, unedited versions of your own photos, messages, medical records, receipts and notes about what happened. Those materials are what a case review works from. A file that has been cropped, edited or deleted may no longer show what it once did.

Most people facing this are still recovering from the attack itself, or caring for someone who was hurt, or grieving a family member. At the same time, they are holding a phone full of pictures and texts, a stack of hospital paperwork, and a lot of uncertainty about what to keep. This page explains what preserving your own records means in a negligent security case, why the condition of those records matters, and how courts treat evidence that goes missing.

What Preserving Your Own Records Means After a Negligent Security Incident

In practice, this means the photo as your phone first saved it, the full text thread rather than a cropped screenshot, and the discharge papers exactly as the hospital printed them, with nothing edited, deleted or thrown away.

A negligent security claim is a kind of premises liability claim. Premises liability is the area of law that asks whether the person or business that owns or controls a property used reasonable care to keep the people on it reasonably safe. In a negligent security case, the question is usually whether the property controller knew or should have known of a foreseeable risk of crime and took reasonable steps in response. The site's overview of what a negligent security lawyer handles explains that framework in more depth.

This page is about your own records, the things you, a family member or a witness created or received. That is different from the property's records, such as its camera footage, guard logs and incident reports. Asking a property to keep its video is a separate topic, covered in the site's guide to negligent security evidence preservation.

For someone in your position, the stake is simple: an attorney reviewing a possible claim works from what actually exists, not from what someone remembers having saved. A useful first question to weigh is which items on your phone, in your mail and in your closet relate to the incident, so they can be set aside before routine habits clear them out.

Which of Your Records Usually Matter in These Cases

If you are wondering whether your materials can help, it helps to know what a claim has to show. Almost every negligent security claim turns on four questions. Duty asks what obligation the property owner or manager may have owed you. Breach asks whether they failed to meet it. Causation asks whether that failure is linked to your injury. Damages is the legal term for the losses the law may allow a person to recover for, such as medical expenses, lost earnings and pain and suffering. Whether any of these is met depends on the facts, and an injury on a property does not by itself prove anyone was at fault.

Your own records can speak to each question. If you were hurt, the records that usually matter include:

  • Medical records and bills from the emergency room, follow-up visits and any ongoing treatment, which show the injuries and their course.
  • Photographs and video taken by you or by witnesses at or near the scene, including lighting, doors, gates or locks as they looked that day.
  • Texts, emails and other messages about the incident or about the location, including earlier messages that mention problems there.
  • Any incident report or police report you received a copy of.
  • Receipts, tickets, a lease, a parking stub or other records showing you were at the location.
  • Names and contact information for people who saw what happened.
  • Personal notes or a written account made close in time to the incident.
  • Pay stubs, schedules or employer letters showing time missed from work or lost income.

The value of a record often depends on when it was made and whether it has changed. Digital photos and videos usually carry metadata, the hidden information a device stores with a file, such as the date, time and sometimes the location it was taken. An original file keeps that information. A screenshot, a cropped image or a file sent through some apps may strip it away. Photos of a broken gate or lock can matter here too, and the site's page on broken access controls explains what the law asks about them.

What this means for you is that a photo of a dark entrance or a text about earlier trouble may bear on duty or breach, while bills and pay stubs bear on damages. Many people use this list as a checklist, noting which items they have, which a witness or employer may hold, and which they are unsure about to raise in a conversation with an attorney.

Why a Deleted Photo or Message Can Affect Your Case Review

A missing or altered record leaves a gap, and gaps cannot always be filled later. If the original of a photo is gone, the date it was taken may be impossible to show. If a message thread was deleted, what was said about the property before the attack may be lost.

The law has a name for this problem. Spoliation is the loss, destruction or significant alteration of evidence that is relevant to a legal claim. Depending on the rules that apply, a court may draw an adverse inference, which means treating the lost evidence as if it would have hurt the party who lost it, or it may impose other sanctions. Those are things courts may do under particular rules and facts, not a prediction about any person's case.

Whether a party had a duty to preserve evidence, and when that duty began, is a fact-specific question. Courts often look at whether litigation was reasonably expected at the time the evidence was lost. That question can apply to the injured person's materials, not only to the property owner's.

Some ordinary actions can make a record less useful or unavailable. Editing a photo, running it through a filter, or changing its date can alter its metadata. Deleting a message thread to free up phone storage can erase the only copy. Throwing away torn clothing or a damaged phone removes a physical item that might have shown something about the event. If you are living through the aftermath of an attack, none of this is likely to be on your mind. A person in this position may weigh pausing phone cleanups and setting damaged items aside, and may ask an attorney when a duty to preserve could begin on facts like theirs.

How Federal Courts Handle Lost Electronic Records — and Why State Rules Differ

Federal courts follow a written rule on lost electronic data. Rule 37(e) of the Federal Rules of Civil Procedure addresses electronically stored information, such as emails, texts, digital photos and video files. The rule provides:

"If electronically stored information that should have been preserved in the anticipation or conduct of litigation is lost because a party failed to take reasonable steps to preserve it, and it cannot be restored or replaced through additional discovery, the court: (1) upon finding prejudice to another party from loss of the information, may order measures no greater than necessary to cure the prejudice; or (2) only upon finding that the party acted with the intent to deprive another party of the information's use in the litigation may: (A) presume that the lost information was unfavorable to the party; (B) instruct the jury that it may or must presume the information was unfavorable to the party; or (C) dismiss the action or enter a default judgment."

The rule works in two tiers. Under the first, if lost information harmed the other side, the court may order measures no greater than necessary to cure that harm. The stronger measures in the second tier, a presumption that the information was unfavorable, a jury instruction to that effect, or dismissal or default, are available only if the court finds the party acted with intent to deprive the other side of the information. Each tier also requires that the information should have been preserved, was lost through a failure to take reasonable steps, and cannot be restored or replaced.

Rule 37(e) applies in federal court. State courts have their own spoliation rules, and those rules differ from state to state and from the federal rule. Because negligent security claims arise under state law, many are filed in state court, so the federal rule is one reference point rather than the standard everywhere. Which rule governs depends on where a case is filed, and that is one of the questions a person may raise with an attorney when asking how lost files would be treated in their state.

What Keeping Records Safe Actually Looks Like

Injured people and families often keep copies of their materials in more than one place: the original on the phone, a copy in cloud storage, another on a separate device or drive, and printed copies of key documents such as medical bills and reports. For you, the stake is that a broken or lost phone does not have to mean lost evidence; if one copy disappears, the others remain.

Keeping files in their original format tends to protect the most information. A photo kept as the camera saved it, rather than converted, cropped or resized, keeps its metadata. A full message thread, exported or photographed screen by screen in order, shows more context than a single cropped screenshot.

Many people sort materials into folders by type, such as medical, photos, messages and work, and name files by the date of the event they show. A simple list of what exists and where each copy is stored can make the collection easier to follow.

A written account is one of the few records only you can create. People often write down what happened as soon as they are able: where they were, what time it was, what the lighting and entrances looked like, who was there, and what they saw, heard or were told, including anything said by staff or security. Noting the date the account was written shows how close in time it was made. The site's guide to preparing for your first consultation describes how such an account fits with other materials.

Not every item turns out to matter. A conversation with an attorney can help a person understand which of their materials bear most on the legal questions their particular situation raises, and which are background.

How Fault Rules and Deadlines Vary by State

State law governs negligent security premises liability cases in the United States, so the rules that decide a claim depend on the state, including limitation periods, fault rules and damages rules.

If you are considering a claim, the filing window is the first rule that touches you. A statute of limitations sets the period within which a claim must be filed in court. It differs by state and by the type of claim, and a claim filed after the applicable period has run may be barred. When the period starts, and whether any exception applies, depends on the state's law and the facts. A wrongful death claim, which is a claim brought by certain family members or a representative after a person dies because of another's wrongful conduct, often carries its own limitation period under state law.

If you worry that something you did that night will count against you, the state's fault rule answers that. Under comparative fault, an injured person's own share of fault, if any, may reduce what the law allows them to recover, and in some forms may bar recovery past a certain point. Under contributory fault, a stricter rule, an injured person's own fault can bar recovery. Which approach applies depends on the state, and which state's law governs can itself depend on facts such as where the incident happened and where the case is filed.

For a family trying to understand the timeline in front of them, the starting date of a limitation period and the state whose law applies are often the first unknowns. Those questions can be raised in a conversation with our attorney, along with how the fault rules of that state treat facts like these.

Frequently asked questions

What does "preserving records" mean in a negligent security case?

It covers more than files on a phone. Paper discharge instructions, a torn jacket or a cracked phone screen are records too, and keeping each one as it is, without editing, deleting or discarding it, gives a later review an unmodified picture.

Which records matter most after a negligent security incident?

It depends on which legal question is in dispute. Scene photos and earlier messages about the location often relate to whether a risk was known, while bills and pay stubs relate to losses. Original, unedited files are usually more useful than screenshots.

What is spoliation of evidence?

Spoliation is the loss, destruction or significant alteration of evidence relevant to a legal claim. An everyday example is deleting a message thread to free up storage. Depending on the rules and circumstances, courts may respond with measures ranging from steps to cure the harm to jury instructions or dismissal.

When does the federal spoliation rule apply?

Rule 37(e) of the Federal Rules of Civil Procedure applies to electronically stored information in federal court cases. It does not reach a torn piece of clothing, for example, since that is not electronic. State courts have their own spoliation rules.

What can happen if relevant records are lost or deleted?

In federal court, Rule 37(e) lets a court order measures no greater than necessary to cure prejudice from lost electronic information and, only on a finding of intent to deprive, presume the information was unfavorable, instruct the jury so, or dismiss or enter default. An accidental loss and a deliberate one are treated differently. State rules have their own standards.

How long do I have to file a negligent security claim?

Statutes of limitations differ by state and by the type of claim, and wrongful death claims often have their own periods. When a period begins to run and what exceptions apply depend on the law of the state involved and the facts, which is a question for a conversation with an attorney.

Does it matter if I was partly at fault for what happened?

It can, and the answer depends on the state. The same facts may reduce a recovery in a comparative fault state and bar it in a contributory fault state, which is why the governing state matters.

Is a screenshot as useful as the original file?

Usually not. A screenshot of a photo shows the image but may drop the date and time stored in the original. People often keep originals in their first format and store copies in more than one place.
