From the description of the collision contained in the question, there is no way of clearly determining the scene and what occurred.
yes
If you back into somthing its your fault regardless of whether it was parked improperly or not. You were suposed to be looking
Most defintley his fault, you were backing out, he should have saw you first.
Need more information, where is your damage exactly, where is the other partys damage/impact. If you had control of the lane, then the other party will likely carry the majority of fault. If you could give me more details I could be of greater assistance to you.
Were you both backing at the same time 'at impact'? Will depend on where damage is etc, but assuming both backing and bumpers hit more than likely will be a 50/50 liablitly decision made.
Assuming that the car hit was stopped when the other car was backing up, the one backing will be at fault. If there is no damage, or if it is below a certain threshold it may not even count as a collision.
I'm confused by the question. You were both backing? And back into each other? If that is correct more than likely you will each be 50% at fault. If you can provide more information (ie, where on each vehicle exactly is the damage, who was farther out etc), then perhaps I can be of more assistance.
The car which is driving straight into the parking lot has the right of entery into the parking space. When you are backing out your vehicle than you need to make sure that there is no vehicle which is comming in and whether it is safe. If you have already backed out more than 50%, than the car comming in should wait till you clear out . As per the state prevalant laws it would differ from state to state. However, each one will have to claim for the damage of the vehicle under your own policy and if there is any bodily injury than you can sue the opposite driver. However, the award for property damage and injury would be paid in porpotion to the fault fixed.
That's their fault they should look out first before they do anything, some people shouldn't drive and if they make any damage then they will have to pay for what they have done!
If all conditions are equal: such that both parties signaled and backed up in a 'cautious manner' - then the fault would be 50-50. The amount of damage would have no bearing.
Internal engine damage.
The best remedy is to learn how to drive properly. Second, install rear parking sensors. Rear parking sensors protect from damage to the vehicle and harm to people, rear parking sensors also protect drivers and others from property damage.
