I agree with the thejeff. I always spell the terms out. As I usually play
with very low dominion, I include a provision about temples on the borders,
and a predefined border - thus, we both expand in other directions, and take
at leisure the lands in which we could have bumped heads.

There is one important thing about treaties - unless they are advantageous
for both sides, they will be broken. And of course, at some point, they stop
being advantageous to both parties. But I seriously cannot remember the last
time someone has broken a NAP with me.

Alliances against a common enemy are a different story. When the time comes to
share the spoils, there are always problems. Every single freaking time I can
think of. Nowadays I spell out the division of every single enemy province, and
the military obligation of every ally before I start a joint invasion.
