Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Who will the children live with?
What exactly is it that you wish to know?
What income do you each have?
How much is the house worth and how much is outstanding on the mortgage?
Has she agreed the sale?
So you earn much the same and she has no wish to keep the matrimonial home
You will share the children equally - is that all correct?
Do you have similar pension provision?
Given the agreement that the house is sold and the money divided; the fact that you earn much the same and the pension provision is balanced there is little chance of either of you making a successful claim against the other for your personal support.
From what you have said the children will share their time equally between you so Child Maintenance is not an issue either.
It is possible that you will end up paying for the activities that you (and the children) wish the chidlren to do - but there is no way around that I am afraid.
Please ask if I have not dealt with what you are actually concerned about!
You are most welcome I hope all goes well
