T.M.K., M.L.K., R.J.R. Missouri Cases

Appellant S.A.K., individually and on behalf of her children, appealed the trial court's judgment finding Respondent T.M.K. to be the natural parent of the children, despite blood tests showing no biological relation. The children were conceived via artificial insemination during Appellant and Respondent's marriage, using third-party donors. The appellate court affirmed, holding that the Uniform Parentage Act must be read gender-neutrally, allowing the trial court to weigh conflicting presumptions of parentage (marital vs. biological) based on policy and logic. The court clarified that blood tests are conclusive for nonpaternity when a party seeks to disclaim a biological relationship, but not to prevent a spouse from being declared a natural parent, and that non-compliance with artificial insemination procedures does not preclude a finding of natural parentage.
