If you are on private property and you are pulling in front of a car on the right and as you're pulling over they pull forward and hit you who is at fault and who is liable to pay for the damages?

Of course the party that is deemed 'At Fault' will owe for the damages to the innocent party, or perhaps some comparative on each. The insurance companys will sort this all out in their investigation. Too many things go into this that you were unable to provide, (ie where is the damage on each vehicle, who had 'control' of the ''road'' etc)...
