Will my earnings affect what the CSA will pay me?

June 30, 2012

I have two children from a relationship with my ex partner. At present he pays 150 per month collectively for both children.

He also has a son from a previous relationship to which he pays 150 per month or so I’m led to believe. He now lives with someone who has 3 children of her own. Whether she is claiming CSA I do not know but my ex has now told me he would prefer to go through CSA with regards to child payment. He is self employed.

When making such claims is my income relevant and will the children to his current relationship (which are not his) affect what I will get? Am I correct in thinking he would pay 15% of his annual net profit per child for the year?

Sorry so many question. Help?
