Can an illegal mother obtain child support form citizen father? If she gets deported, does the support stay in force, or can be challenged? Details. I had an affair with a Indonesian mother who is illegal here in California. She said she would not sue me for support, but did, and is getting close to $1000 a month. If she was deported, can she still collect, or can I challenge? Can I get custody of the child? He was born in California.
