The general time limit to file a medical negligence claim is three years from the date of the negligence or three years from the date of knowledge of negligence. However, there are exceptions to this. An injured child, or minor, has until his or her 18th birthday to bring a claim with the support of a responsible adult, most often a parent, but may be another person, or ‘litigation friend’ who can protect his or her best interests. On the child reaching 18 years, he or she will usually bring the case in his or her own right, and will have until the 21st birthday to issue proceedings at court. In cases where the child is brain injured and suffers the incapacity of being unable to provide instructions, there are no time limits.
