Angela Bauer told The Topeka Capital-Journal on Saturday that she and her former partner, Jennifer Schreiner, are "kind of at a loss" about the Kansas Department for Children and Families' recent decision to file a child support claim against William Marotta.

William Marotta, the Topeka, Kan., man whose sperm donation in 2009 enabled a lesbian couple to have a child, now might find himself forced to pay child support. Marotta talked about his ordeal at his attorney's office in Topeka Monday, Dec. 31, 2012. The state of Kansas is trying to force Marotta to pay child support, arguing that the agreement he and the women signed releasing him from all parental duties was invalid because they didn't go through a doctor.
