Often in Ireland the term contributory negligence crops up in regards personal injury claims. In essence contributory negligence refers to how much, if any, the claimant has contributed themselves to the harm they suffered through their own negligence.
For example, if you cross the road at a corner with no pedestrian crossing and you happen to get hit by a car, this could be considered contributory negligence. Another common example where claimants involved in accidents were not wearing their seatbelt and this contributed to the seriousness of their injury.
The degree to which you were deemed to be personally negligent will obviously have an effect on the amount of compensation you receive. This is usually determined in the courtroom.
