I don't know where you get your information from, but it's completely WRONG.
Lawyers charge between 33-1/3% and 40% generally and certainly, they reveal this upfront to any potential client
No such thing that dealing with an insurance company will bring a client more money than if he or she consulted an attorney (providing the injuries are significant). Playing the waiting game from an insurance company can also mean the statutes can expire and insurance companies know this and are willing to drag it out.
Insurers know, and tell their adjusters during training, that in the most common personal injury claims, "represented claims when an injured person uses an attorney] settle for 2-3 times more than unrepresented claims [when a person deals directly with the insurer--even after deducating attorney fees."
REF:Allstate Unrepresented Adjuster Training Manual, July 1995.
Unless you know what you are talking about, you should not post misleading information.
Anyone who has potentially serious injuries which require long-term treatments should consult an attornejy.
