Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
What is your gross annual income and what maintenance are you currently paying?
Does the £800 a month include spouse maintenance?
Who owns the property you and your current partner live in?
My apologies for the delay.
Under the CMS(CSA) rules you would be paying approximately 16% of your gross income as child maintenance split as to two thirds to your ex wife and one third to your current partner - which (again very roughly) means a payment to your current partner of about £500 a month.
Full details here
Your partner could potentially also apply for an order forcing you to also find her a small two bedroom property which would remain yours but in which she could live until the child is 18 or she cohabits - but that is less certain.
She has no other claim on you.
If your income reduces your child maintenance will reduce and remain a percentage of your gross income from all sources.
I hope that this is of assistance - please ask if you need further details
It can still work - but only if the pension contribution remains "reasonable" (yes who knows what that might mean!)
Sorry - they said that the full 16% would go to your current partner who only has the one child?
In the event that the other chidlren were ignored (which they wont be) then it would not be 16% - it would be something like 10% of your gross income for one child (at most)
You are correct - it is about what is a reasonable property - bearing in mind it is important that the difference between your property and hers shoudl not be too great so that the difference as the child moves between you is not too extreme

Think of it more like this - if you have a five bedroom detached house in a nice area - she will need more than a two bedroom ex council flat in a tower block!
