What do I have to Pay for?

She wouldnt be entitled to all of your disposable income, but a court might consider it fair to balance your incomes in order to provide a home for the children.

Do not move out until your ex is paying for the mortgage or you might find yourself having to pay cm and the mortgage to stop the house being repossessed.

Check on the CSA calculator if the £420 figure is right.

If the mortgage is £900 this would reduce your CSA payment considerably if you applied for a variation, possibly to next to nothing, call them to check.

I agree with Mathisfun you need to be careful about moving out, it will weaken your position

Its kinda funny, I am in a house with a woman who has completely moved on from me. I hate being here and all I get is stay it will weaked your position.

Talk about mind screwer lol

I will stick here and stick it out. but I need out, or in, the courts will decide

Look mate

Theres a whole list of things you have to put down before anyone can give you any relevant on advice on what you should do based on the finances.
I never know what it is but some right helpful wiki person who isn''t a neanderthal will no doubt post it shortly.
After that when I post read what I advise carefully because I am always right and read all these outcomes financially far better than any lawyer judge Divorce Calculator ever.
I am a fecking genius at seeing the angles.
Dukey and little Mr Mike will concur.
When it comes to predicting an outcome and what your moves should be based on this I''m like Mystic Meg of the divorce fraternity.

All the best
