That all depends on the type of accident, and where your car was hit at. A bunch of variables can be at play. This is something your insurance company would have insisted on you having checked out after the accident... Did they?
If you really would like to look into it, you'll want to go to collision repair shops and ask for a "Frame Alignment Machine" as it is not the same as your normal alignment machine. They will check several different points to where the body is mounted on the chassis and the subframes. They will be able to tell you if your body is even out of spec by 1mm.
