FIB, just some examples of what I had in my agreement:
Visitation-be as specific as you can be...including holidays.
No overnight guests of the opposite sex when the kids are present (unless married).
No alcoholic beverages to be consumed by the parent when he/she has the kids. (Unfortunately my ex is constantly breaking this one...may be back in court soon.)
Make sure you are kept informed of any school or extra-curricular activities...also, grades, report cards, etc.
Somehow insurance got left out of our agreement...make sure someone has insurance on the kids.
Some of my friends have college money in their agreements.
If either of us plan to take the kids out of state, we have to give the other parent one week's notice, where we are going, and information on how to get in touch w/ the kids.
We have to notify each other of any changes in address or contact numbers.
And, we have to give the other parent at least 30 days notice if we plan on moving....especially if it is going to affect the visitation schedule. If it does, we have to go back to mediation and re-do the visitation schedule.
I'm not sure if this is what you were asking for; but, I hope it helps.
We are all rooting for you, FIB. I can't wait to see what life has in store for you next!!
