yeah, first check would need to be if there was any play in the hinge pins, open the door and grab the open end ,try to move it up and down there should be very minimal movement.
if there is movement, get a mate to see where it is while you move the door ,they are common for breaking hinges off the pillar, and pins wearing out.
either is fairly simple to sort out.
after that, you need to check the shut gap and see if thats ok, if it is you have a wing prob.
but there are ways of adjusting the gaps if you know how ,ie blocks of wood

but be carefull!
ps there are special hinge pin removing tools for these!
