You've
already paid the taxes and the other person can make off with the assets. If
you retain enough control the transfer will be disregarded. Try again,
boy.

Skitchy, please explain how my wife "can make off" with the boat. Our
agreement
specifically lists any items brought into our marriage as co-owned.

This is the non-prenup, pre-nup (actually sounds like the opposite of one -
weird)? Methinks you got bad advice, my friend. What benefit are you getting
from this arrangment? Be honest with me, and I'll help you. If you have an
agreement that provides that despite her having title you co-own things, then
the agreement removes the benefit of not owning it - you own it. On top of
that, the agreement may not be enforceable - leaving you high and dry. Just
don't get divorced, or fix it first.
