That's a pretty bad crack.
Did this happen gradually over years, or relatively suddenly? One side
of the door frame is sagging compared to the other. This usually
means the floor structure under the door frame is sagging. There are
lots of possible reasons for it, some innocuous, others indicating a
serious structural problem. If it happened suddenly, it is more likely
to be serious.
First step is to determine (call a pro if necessary) whether there is
a structural problem. If there is, proper fix will depend on the exact
If not, and it's due to normal settling, you can patch the crack and
plane the door and it will be ok for a while.

Better get some help soon on the settling problem. You need to determine
whether the settling has stopped or is likely to continue. If it can be
mitigated or corrected, then is the time to address the door out of square

repeatedly for years to come.
Check with neighbors to see if similar homes by the same builder have settling
difficulties. You may wind up hiring a structural engineer or (shudder) lawyer,
but no one should have to accept substandard work in their home. Good luck.
Thanx all for your replies.
Our house is the only one on the street built by this builder so
checking with others would not help.
The house is 5 years old - would the builder still be responsible for
making the fix on his own dime if this were a structural problem?
Any idea what a structural engineer would do to determine if this is a

has stopped settling. If you can't get to it to jack it up
(probably about 1/4 inch to close the crack, go ahead and
tape and mud the crack and then apply ?paper? over it. You
don't need to square the door just caulk and trim the door.
Fill the open joint with caulk or if you prefer a wood
filler and paint. Note where the door binds, remove the
door, and plane it (or use a belt sander), and check before
removing too much, and repaint that area of the door edge.
