What do I need to do to ensure my ex-partners income is not including in my ‘annual family income’? I am responsible for paying child care but with his income and mine, we are subject to the annual cap. Which means 6 months of the year I am paying $2000 a month for care. We have 80/20 shared custody. Very amicable, no court orders. It seems grossly unfair that our income is combined despite being separated and paying double living expenses such as rent, utilities etc.
