What is the name of your state? Florida
He wants to change it where I drive the kids both ways one month, and he does the other month. However I can not drive on the highways, I get nervous, its a 2 1/2 hours drive one way and I also have two other children from my current marriage.
The Courts may very well order this, not worth the fight, have your current husband etc do the driving if you cannot.
He also wants to now keep the children for the two summer months regardless of his job schedule
Again he could up to 6 weeks or even more, can you compromise on this with him? again, again, childcare on his parenting time is his deal. The fact he is working is not going to get in the way. Most of us on this site are single working parents and our children are in daycare, preschool, after school programs etc, when we do... way of life here, stay at home Mum theory won't get far in the courts.
and because this will affect him financially he wants to not pay child support during those two months.
This I dont get? you are still the CP, he still has to pay child support, regardless of whether he has them for 2 weeks in the summer or the entire summer. He would not have to pay CS is (a), he makes less than you, b) you have a 50-50 schedule and he makes less than you.. both dont apply here in your case.. so correct him on this
So my question is.. Can previous agreements be changed just like that ? He says the circumstances has changed and therefore wants it changed.
Circumstances have not really changed but he can try to litigate this.
I once talked to a lawyer and basically he said that changes are not easily made. Judges and courts do not like to waste time with type of cases? That there has to be a major reason for the change...... but how major ?
Major!
What can happen if he does files for another mediation?
You folks mediate and work it out!!. Mediation is the best way to go, rather than have a court decide, the two of you know your children's needs best.
