If any of the following pertain to you and your claim, you may want to take into consideration contacting an attorney:
-At any point in time you feel negotiations are not going how you expected.
-You have serious injuries and/or pain and suffering and are demanding compensation beyond a few thousand dollars.
-You believe you will need to claim future damages such as: future medical issues that may result in time off to recover or loss of income. An attorney will effectively work that into your settlement.
-If for any reason the validity of your claim is brought into question of fault. It is best to get an attorney that can draft your argument properly.
