Imagine you see an ad on Craigslist from a lesbian couple seeking a sperm donor. You and your wife mutually agree to meet with the couple, who are desperate to conceive a child. At the conclusion of that meeting, you agree to donate your sperm in order to help them conceive a child. The agreement is reduced to a contract signed by both parties, which outlines all terms and conditions, including a provision stating that in exchange for your sperm donation without compensation, the couple agrees to relieve you of all of your parental rights and responsibilities if a child results from your sperm donation. Then, three years later, you receive notice that the State is suing you for back child support. This sounds like a script to a bad Hollywood movie, but not for William Marotta and not under Kansas law.
