My question involves child support in the State of: Washington
My ex husband and I have been divorced for 10 years. We have 3 children. Up until a year ago, I had our two younger children and he had custody of the older. Last year, the oldest came to live with me so now I have all three kids. We have never really fought over child support, he just paid me what he could afford, which was pretty decent, 300 at first then 600 when I got all 3 kids.
Well the big issue is our middle child. He is not my ex's child (no, I dont know who the father is - drunk night with a bad decision). My ex has always known this and infact we seperated for a while during pregnancy then got back together before he was born. My ex was at the birth, cut the cord, signed the birth certificate and has always claimed him as his son. He has always paid support for him and provided him insurance and claimed him on his military things. He has been his dad for almost 15 years.
I have recently told him I want him to start paying what is the proper amount for 3 kids. Now I am wondering if he will be legally responsible to continue to pay for the middle child. Or if after 14 years he will be able to deny the child.
