You do not have to use a solicitor, but clinical negligence claims can be difficult because you usually need to prove that the treatment fell below a reasonable standard and caused avoidable harm. A solicitor can obtain and assess medical records, arrange independent expert evidence, calculate losses and deal with the healthcare provider or insurer. Time limits commonly apply, often three years from the incident or when you first became aware of the possible negligence, although exceptions can apply. Consider speaking to a solicitor regulated by the SRA who handles medical negligence before deciding how to proceed.
