If my ex-husband has our son every other weekend and I have him the remainder of the time what type of child-support am I looking at to receive from him. His gross income is $4600.00 a month. Right now I'm on disability for 2 months my rate is $417 per week. My regular salary is $3,240.00.

What should my ex-husband pay in child support?

Child support amount vary by state. Without knowing what sate your living in it would be hard to say. Also most states have an online calculator.

We live in CA.
