A medical negligence claim generally requires evidence that a healthcare professional owed you a duty of care, breached the required standard and caused avoidable injury or loss. Start by writing a timeline, keeping correspondence and expense records, and requesting your medical records. Court proceedings usually need to begin within three years of the treatment or the date you reasonably knew about the possible negligence, although exceptions can apply. A solicitor regulated by the SRA can assess the evidence, limitation issues and possible funding options. An NHS complaints process may provide answers, but it does not necessarily stop the legal time limit.
