This is a civil matter question. My cousin was 16 years old when she got into a car accedent and was injured. Her mother and her put in writing that if i did all the researching and called lawyers and made appointment for lawyers to come talk about a settlement. If the settlement was more then $5500 she woud give me $1000 for my childrens school clothes. since she was a minor at the time can i sue her in court now that she is 18 years old?
