Am I likely to owe child support?
I live in California and have a question about child support. My children's father and I share 50/50 legal and physical custody of our three younger children, the three children stay with me from Friday 7PM till the following Friday 7PM. However, I currently have 100% physical custody of our oldest child, who has the same father, and I never asked for any support from him for this child. However, she will be turning 18 in about three months. Recently, I learned that their father applied for government assistance (CalWORKs) without informing me. I am the higher-income parent. Given these circumstances, am I likely to owe child support? Will the court consider that I currently have sole physical custody of our oldest child, even though that child will turn 18 in three months? How does California calculate child support in a split-custody situation where one parent has sole custody of one child and the parents share 50/50 custody of the other three? Once my oldest child turns 18, how might that affect any child support calculation? Also, how does his receipt of CalWORKs or other government assistance affect the child support determination, and does it automatically require the state to pursue child support from me?
