First of all, there is an entrustment contract between the lawyer and the client, and the matters entrusted and the lawyer's fee are clearly stipulated. If the fee increases, you can refuse and complain to the local lawyers association or the judicial bureau.
Secondly, for personal injury, the main scope of compensation includes medical expenses, hospitalization expenses, nursing expenses, nutrition expenses, lost time, one-time disability allowance, mental damage compensation and so on. The foundation is based on disability grade appraisal.
Blessing!
