Most likely it will be considered your fault.
I know of a case where a person opened a door on a narrow road and it was struck by another vehicle driving down the road. The person opening the door was at fault. Your situation sounds a bit different but the person opening the door may be at fault.
Technically it would be the fault of the person opening the door. You are not supposed to put parts of your car into the path of a car. Having said this, no accident is ever 100% someone's fault. In Wisconsin you are 10% at fault just for being there.
Opening a door into traffic makes the door opener at fault. If the door is opened safely and some driver then runs into it, the moving driver is at fault.
the person who parked the car
In general, the moving car would be at fault because pedestrians always have the right of way. However, under certain circumstances, it could be the door-opener's fault.
With garage door opening probably the fault of the driver. With a closing door driver could be not at fault if someone closed it on top of car. But opening should be seen by driver. Like running into a closed door that's not moving. Unless someone told the driver it was open and it wasn't and so the driver hit it backing out. Or it was open then someone else closed it and started to open it again.

The only situation in which there may be an exception to this is if you were in a parking lot and the other car pulled in beside you after you had already begun opening your door.
It varies by country and/or state. In most areas, the person opening the door is liable for any damage.
The driver/passenger opening the door is at fault. Look it up under the traffic laws in your state.

The other driver's fault. He or she should have paid attention.Another View; IT DEPENDS. If you opened the door to a traveled lane and it was struck by passing traffic - YOU are the one at fault.
