On March 16, 2021, Utah Governor Spencer Cox signed House Bill 113 into law.  This short legislation greatly expands Utah’s existing prenatal child support requirements by pulling and combining aspects found in other states.
Previously, the Utah Code only contained vague sections under Title 78B relating to non-resident jurisdiction  and admissibility of the mother’s prenatal costs to court for reimbursement  to meet Federal minimum requirements .
With the passage of House Bill 113 — effective May 5, 2021 — a father will be expected to equally split prenatal costs with a mother before birth or reimburse an equal split of costs after establishment of paternity. These equally-divided costs include health insurance premiums and direct medical costs during pregnancy from conception until after the hospital stay for childbirth. If the mother has an elective, induced abortion for which the father did not consent (aside from one after rape or incest), he is exempt from any prenatal child support payments.
Every US state and territory has some baseline level of prenatal child support requirements , but requiring the father to explicitly pay at least fifty percent of health insurance premiums or prenatal expenses is not too common.
Hawaii is the only other state to mention a health insurance premium requirement, coming under Hawaii Revised Statutes §584-15(c) .
Existing child support statutes that explicitly require a father to pay at least fifty percent of prenatal expenses include:
- Official Code of Georgia Annotated §19-6-15(a.1)(2): “the amount of direct… expenses” 
- Indiana Code §31-14-17-1: “at least fifty percent” 
- Iowa Code §600B.1: “pay the expense” 
- Texas Family Code §160.636(g): “an equitable portion” 
- American Samoa Code Annotated §45.1505(c)(4): “any expenses” 
Additional historical examples include:
- Minnesota General Statutes §17.3219: “all expenses necessarily incurred” 
- Oregon General Laws Title XXI §2554: “all expenses incurred” 
- Wisconsin Territorial Statutes (uncodified): “all costs and expenses incurred” 
(Many other laws use terms like “reasonable expenses,” “all or part of,” or “liable for,” that can be open to interpretation.)
With Utah’s passage of House Bill 113, the state’s prenatal child support requirements moved from being among the least in the nation to becoming a new benchmark worthy of emulation.
