Alabama is one of only a few states in the nation that has what is called contributory negligence. This means if you, the injured victim, were at fault in any way for the car wreck, slip and fall, etc. then normally you cannot recover any damages against the party that was primarily at fault.
Most states have something called comparative negligence which means that the court “compares” your degree of negligence with the degree of negligence of person or company that you sue. Normally your damages will be reduced by whatever percentage you are at fault.
But in Alabama if you are even 1% at fault, the normally the defendant will win the case based upon contributory negligence.
