When To Sue For an Injury

Here are the basic things you'll need to consider before you sue for an injury.

Most people will experience some form of injury at some point in their lives. Of course, not every injury gives rise to a legal claim -- some injuries are attributable to age, genetics, or an accident that was unavoidable (and no one's fault). But when another person or entity is legally at fault for the incident that led to your injury, you may have a valid legal claim – and grounds to sue. Read on to learn more about when you might have a civil case, and what you’ll need to prove.

Do You Have a Legal Claim?

A legal claim can be made through a personal injury lawsuit or insurance action, and lets you recover compensation for damages, usually when someone else is legally responsible for causing the accident or creating the circumstances that led up to the injury. The purpose of an injury claim is to allow the injured person to recover compensation for the injury -- including damages in the form of lost wages and medical expenses, and even compensation for emotional distress and pain and suffering, where appropriate.

What You Need to Make a Case

If you want to make an injury claim (either through an insurance claim or lawsuit), you usually need to be able to prove that the person you are making the claim against was negligent -- meaning that they breached a legal duty owed to you, and that the breach led to the accident and your resulting injuries. You also must be able to prove that you suffered actual damages as a result of the injury.

Under personal injury law, the burden of proving these elements is placed on the person making the claim. If your claim ever makes it all the way to trial, the legal standard by which you must prove your case is by a preponderance of the evidence, which means you must prove (to a judge or jury) that more likely than not, everything you are alleging is true, regarding the cause and extent of your injuries, and the defendant’s liability. In all likelihood, your case won’t make it to trial, let alone to the verdict stage, but in assessing the strength of your case, it helps to think in terms of whether you can successfully meet this burden.

Keep in mind that not every injury case will come down to the question of whether or not the other party was negligent (though most cases will). If your injury was caused by a defective product, a workplace accident, or an intentional act, your claim will follow different rules (refer to the chart above). For example, if you suffered an injury while on the job, you’ll most likely need to file a workers’ compensation claim under the procedures in place in your state. In almost every workplace accident, the injured worker is barred by law from suing his or her employer.

Evidence Necessary To Prove Your Claim

So, assuming the kind of lawsuit you’re bringing requires you to establish that another party (the other driver in a car accident case, or the business owner in a slip and fall case, for example) was negligent, what kinds of evidence might you need in order to successfully prove the element of your case? The possibilities include:

  • A police report documenting the circumstances and cause of a car accident
  • An incident report prepared by a store, restaurant, or other business where a slip and fall occurred
  • Eyewitness statements attesting to the details of when, where, and how your injury occurred
  • Photographs from the accident scene and any evidence that might help document the cause and circumstances of your injury
  • Records of all medical treatment associated with your injury -- including from emergency services, hospital visits, physicians, physical therapists, and chiropractors
  • Documentation of time missed at work, and records showing your typical income, to support a lost wages claim
  • Testimony from a doctor or medical expert regarding the cause of your injury. For instance, if you have a herniated disc, which can be caused by many factors including the natural aging process, your doctor or another medical expert would need to testify that it was the impact from the car accident (or the fall, or whatever the incident that prompted your injury claim) that caused the herniated disc, and that it wasn't simply an existing or unrelated injury.

Should You Talk to a Lawyer?

Determining if you have sufficient evidence to bring a lawsuit can be tricky, especially if you are not certain what type of evidence you need and how to get it. In most cases, it is best to seek advice from an experienced personal injury attorney, who can help you determine if you have a valid case and, if you do have a case, help you prove it.
