*Loan,banking and credit>>>child tax

What are the odds of a mother (primary caregiver)being able to claim child on taxes, if couple doesn't agree?

You need to become familiar with your State Laws. Also, any seraration agreements that you may have signed. Your best bet is to go to your State Department of Revenue site. They have all kids of information pertaining to both tax and child support laws. Please don't just assume that you have the right to claim them or else you can potential get yourself into serious trouble, especially if you are both filing separetly and both claim the kid(s)

if the mother is primary and makes more and is seperated she should just do it.
but if she isnt the bread winner and she is filling joint why would she.
in other words if you are seperated and you have custody claim the child he can claim his suport payments and if he isnt paying suport you shouldnt even ask just look out for your child the best you can.
