What are the pros and cons of Joint custody

Support is based on time with parents, who pays what expenses and who makes more money. Legal custody if you already share time shouldn't affect it. If you don't share time and if your spouse wants to have some time with your son, the courts are inclined to look favorably upon that as they do like to see both parents involved with the children, though only if it is healthy for the child. If you have full custody and he wants time, you can probably provide him with some visitation without lowering your support payments from him.

In any event, as long as he's good with your son and involved, that's far more important than any monetary concerns. The child deserves to have both parents involved and engaged in his life.

As far as the benefits, you'll get a break, which many parents don't get, especially full time single parents. It allows you to recharge your batteries so that when you are with your son, you are a better parent. My ex and I have 50/50 time with our son and that works out very well (though sometimes it's a pain when you don't parent with the same boundaries).

Good luck and I hope this helps.
