A fair settlement range will include the expenses and losses you experienced because of the crash and your injuries and those you will continue to experience.
Each case differs, but common examples include:
Medical bills and all related expenses
Future care and treatment costs
Lost income from the time you took off work
Reduces earning ability if you have long-term injuries
Miscellaneous expenses with receipts
Pain and suffering
Other intangible damages
You will need documentation of your damages, another thing your attorney can help you with.
