Medical negligence law is fact-specific. This guide is intended to explain the general principles in accessible language and is not a substitute for advice on an individual case.

Important: Do not delay seeking advice because of information on a website. Limitation can be complex and depends on the individual circumstances.

When delay becomes legally relevant

The focus is on whether a competent clinician should reasonably have identified or investigated the condition earlier and whether the delay made a material difference.

Measuring the impact

Experts may compare the likely position with appropriate timely care against the outcome that actually occurred.
