Measure if the door is perfect square..
Measure the door frame at both hinges, if the frame at the bottom hinge is narrower, then that door frame and trim needs to be moved wider..Whatever it takes to move it wider, a screw in the frame to the stud,or taking off the trim, and removing shims..
If it's square, and... "lower part of the door is meeting the frame before the upper part of the door"...
So the bottom hinge is not inset like the top hinge, ..There's a bigger gap/ reveal at the bottom hinge, compared to the top hinge,..Then that hinge needs to recess deeper in the door to match the top,..
Take the door off the hinges, and lay it on it's side, with hinge recesses up
cut with a router or hammer and chisel, start small, less than an 1/8.Set the router with a depth of less than 1/8, ...You're cutting only the shape of the hinge..
