How a misdiagnosis claim works

A misdiagnosis claim is a legal process through which a patient seeks compensation after a diagnostic failure causes them harm.

  1. Free initial consultation

We listen to what happened and give you an honest assessment of whether you have a viable claim.

  1. Gathering medical evidence

We request your full medical records and, where needed, instruct an independent medical expert. This stage takes time, but it’s the foundation of a strong claim as thorough evidence is what makes the difference.

  1. Establishing negligence

We assess whether the standard of care fell short and whether that failure directly caused your harm. Not every misdiagnosis is negligence, and we’ll tell you plainly either way.

  1. Pursuing your claim

Most claims settle without going to court. We handle the legal process from start to finish, keeping you informed throughout.
