Modifies provisions of law relating to custody of in vitro human embryos

HB 2789 updates Missouri laws regarding the custody of in vitro human embryos by defining key terms such as "custody," "surrogate," and "third-party custody." The bill establishes a legal presumption that equal parenting time is in the best interest of the child, which can only be overturned with proof of domestic violence or a mutual agreement between parents. It also sets specific guidelines for courts to consider when making custody decisions, including the child's adjustment to home and school, the parents' willingness to foster a relationship with the other parent, and any history of abuse. Additionally, the legislation restricts courts from awarding custody or unsupervised visitation to parents who have been convicted of certain crimes where the child was the victim.
