Anyone know anything about child support??

I'm 28 now and have just recently been teying to think over my life...piece things together.

My parents divorced when i was 4 and my dad was hardlt ever in my life, but he would send money and eventually was made to pay child support....one thing that I am remembering is have to take a DNA test when I was 15 and my mom said it was because my dad didn't believe I was his.

And at one point my mom owed my dad for what she said was "back pay" because my dad was paying more than he should have.

Well now I'm wondering if my mom could have been made to pay money back to my dad because I'm not his biological kid.

Is that something that happens??

My mom is known for hiding all kinds of life secrets, things that would benefit me and my siblings had we known

So it makes me think I'm not his kid and she just didn't tell me.
