You can bet that there is a personal injury lawyer in your area that will help you to determine what your personal injury case is worth.
There is no magical formula to determine this, that is why we have these attorneys that will help you in getting the most they possibly can.
Usually when two sides can not agree your case will go to trial and then you really need a good lawyer in your corner.
Usually they determine the damages as the degree of injuries inflicted on the person injured.
They will take into account damages, loss of work, property loss and more.
The law allows also for loss of intangible harms that sometimes can be hard to determine and usually include, pain and suffering, mental anguish, etc.
Usually you have the jury who decides these amounts and ultimately the outcome of the case.
each side of the case try to determine an amount of damages then they try to agree on a settlement based on this amount.
A case can take many months or years to be settled, a large dollar amount case usually takes longer because the attorney's can go back and forth trying to agree on a settlement that is fair.
The amount can be determined by the injuries and treatment that has been given and also any future treatment that will be needed in the future.
Always remember that each case is different and will have it's own factors that determine the outcome.
It is almost impossible to compare 2 similar cases and try to determine if your case will have the same outcome.
Just the jury members alone can have different opinions on the same facts in similar cases
