from what I understand it depends on the exact circumstances but generally: 50% orthodontists/health (out of pocket w/exception of co-pays), 0% college do NOT agree in writing that you will pay for any college!! If you are in the position and choose to pay for part or all of that later than that is your choice, but you are not obligated.
Travel ice hockey, travel soccer, and clothes…I have been told that if you have joint physical custody than these fees are to be split 50/50. I would imagine if you have sole physical, and this is extremely expensive than the costs could be split 50/50 or 25/75.Try to come to a fair agreement. An attorney will respond also.
