Some personal injury claims are difficult to prove because the injured person generally has the burden of establishing the key elements of the case. When there is uncertainty about the injury, its cause, or who was responsible, proving the claim becomes more challenging. The strength of the evidence, not just the severity of the injury, can determine how difficult a claim is to prove.
Glendale is a busy city in Los Angeles County, sitting just north of downtown Los Angeles near the Verdugo Mountains. It is home to crowded shopping spots like the Americana at Brand and the Glendale Galleria. With freeways such as Interstate 5 running through it, traffic stays heavy, and accidents are common.
After an accident, the question is not just what happened but what you can prove. A personal injury lawyer in Glendale can spot the weak points in a claim early. The reasons below explain why some cases are tougher than others.
You Have to Prove Every Part of Your Case
In a personal injury case, the law puts the burden of proof on you. Under California Evidence Code Section 500, you must prove each fact your claim depends on, such as the other party’s carelessness and the harm it caused. Those parts usually include a duty of care, a failure to meet it, a direct link to your injury, and real losses. If you cannot prove even one required part, the whole claim can fail.
You also have to meet a standard called the preponderance of the evidence. Under California Evidence Code Section 115, this means showing your version is more likely true than not. When the evidence is evenly split, that tie goes against you, not the other side.
Injuries That Are Hard to See
Some injuries do not show up clearly on a scan or X-ray, which makes them easier for insurers to question. These often include:
- Soft-tissue injuries like whiplash and muscle strains.
- Concussions and other mild brain injuries.
- Chronic pain that lingers after the visible healing.
- Emotional distress, anxiety, and trouble sleeping.
Without clear medical images, these claims lean heavily on records and expert opinions.
When the Cause Is in Question
Proving you were hurt is not enough; you must also prove the accident caused the injury. Two issues make this link harder to show.
Pre-Existing Conditions
If you had an earlier injury in the same area, the insurer may argue the pain is old, not new. Clear records from before and after the accident help separate the two.
Delayed or Gapped Treatment
Waiting to see a doctor, or missing appointments, gives the other side room to argue the injury was minor. A long gap can suggest you fully recovered, even when you were simply toughing the pain out at home. Steady, prompt care makes the connection much harder to attack.
When Fault Is Shared
California follows pure comparative negligence. Under it, you can still recover even if you were partly to blame, but your share of fault lowers your payout. That gives insurers a strong reason to pin as much blame on you as they can, turning fault into a second fight you must prove your way through. For example, if you are found 30 percent at fault on a $100,000 claim, you recover $70,000, so every disputed percentage point has a price.
When the Evidence Is Thin
Even a real injury is hard to prove when little supports your account. Claims often weaken when:
- No one witnessed the accident.
- There is no photo, video, or camera footage.
- The scene changed before anyone recorded it.
- The only account is your word against theirs.
The less independent proof there is, the more a case turns on credibility alone.
Key Takeaways
- The injured person must prove every part of a personal injury claim.
- You must prove your case by a preponderance of the evidence, so a tie loses.
- Hard-to-see injuries like whiplash and concussions are easier to dispute.
- Pre-existing conditions and treatment gaps weaken proof of causation.
- Shared fault turns a claim into a second fight over blame.
- Missing witnesses, video, or records make a case rest on credibility.
- Strong, prompt evidence is the best answer to a hard-to-prove claim.
