It would affect his license but it depends on what you are suing him for. If its cuz he didnt win your case, theres really nothing you can do about that. Look up your states laws on lawyers and see if they match your situation
there are two things you can do to an attorney, you can file a malpractice suit or you can file a grievance against them
a malpractice suit is extremely difficult to prove and you must have suffered damages to recover...many attorneys don't carry insurance and are smart enough to hide their expensive assets so even if you did win you wouldn't acquire much
a grievance is merely asking the state bar to look into your complaint and the bar will investigate your claim....a grievance is also extremely hard to prove and you won't win any money out of it but the attorney could get punished with suspension or removal of license
