When Do You Owe Retroactive Child Support

My question involves child support in the State of: Washington

I was curious about the laws of retroactive child support? My boyfriend had a kid right out of high school that he didn't know about about until a year after he was born. The mom kept it from him until she needed to get child support from him which he is currently paying. She is now claiming that he owes her 4000 of retro active child support. She has constantly been aggressive and rude to him though text messages which I have told him to keep but he hasnt. So I am just wondering if she has any pull on this, When he can see his child he does and his parents get to see their Grandchild as well.

Please help me see if she can actually do this, we cant afford to just pull 4000 out of thin air.

Thanks in advance so much.

Very few states will entertain the idea of backdating child support a couple of years before an initial filing for child support. One or two will go back as far as birth, especially if the state was involved in paying for those expenses. Most states will backdate to the initial filing date. However, the answer will be in the court order.

You have suggested that a child support order has been entered. IF that's the case, either he was ordered to pay retroactive child support, in which case he would owe whatever amount was ordered by the court, or he does not, or he was not, in which case there is no debt for retroactive child support. If in association with an action for child support he chose to request visitation, then he can allow his family to see the child during the visitation that was granted by the court. If for some reason he chose not to pursue visitation, he can consider now bringing an action for visitation.
