Yours. If it was stationary and you hit it then it was your fault.
If he was driving forward past his intended parking space to take yours, then he is at fault. Cutting across is not permitted in parking lots although many people do it anyway.
Usually their is no fault associated with parking lots. I'm sure your insurance company looks at it as your fault.
The greater fault lies with the person backing out of the parking space. You may still be partially at fault for not driving with due care.
It would be the person driving fault because it is like the same thing as driving and hitting someone.
The one in reverse is most probably at fault here!
It depends if you pulled out without looking and/or too quickly so as to cut off the car on your right it's your fault. If you were moving very slow and they didnt see you and hit you its their fault. Although.. It is your responsibility as the car NOT in the driving lane to yield to the car IN the driving lane.
If you were backing out of a space and you stopped and the forklift had a REASONABLE amount of time to see your vehicle (about 3 seconds or so), then the forklift operator would be at fault.
In most circumstances, the backing vehicle has the greater duty of care and would be found at fault.
If you are driving the backing car, no matter WHERE the other cas is located, YOU are the one at fault if you collide with it.
In general, the driver who is backing is considered to be at fault.
The driver of the parking car is at fault... he shd allways keep a man to inform him about danger, whenever backing in such a speedy street....
The person who cuts across parking spots, it's illegal. If the parking lot is private property the damage caused in an accident is a civil matter not a legal one in most cases. Traffic laws do not extend to private property.
