You do not have to use a solicitor, but medical negligence claims can involve complex medical evidence, legal tests and strict time limits, so professional help is often useful. In England and Wales, the usual limitation period is three years from the incident or from when you first became aware of a possible claim, although exceptions can apply. A solicitor regulated by the SRA can assess your circumstances, explain funding options and advise whether your case has reasonable prospects. Check the position promptly, as delaying could affect your ability to claim.
