Can a child inherit from both biological and presumptive fathers in Utah? In re Estate of John Clifford Heater Explained

The Utah Court of Appeals addressed a complex inheritance question in In re Estate of John Clifford Heater, examining whether a child can inherit from both a biological father and a presumptive father under different legal frameworks. The case highlights important distinctions between parentage law and probate law.

Background and Facts

John Clifford Heater died intestate in 2008, initially leaving only two known heirs: daughter Gina Kirkland and a son. In 2016, John Carlon learned he might be Heater’s biological son and moved to intervene in the probate proceeding. Carlon’s mother had worked for Heater and stated they had a sexual relationship during the relevant period. Carlon provided evidence of Heater’s paternal behavior, including taking his mother to doctor appointments, paying for a nanny, and sending birthday money for years. DNA testing established 99.99% certainty that Carlon and Heater’s known son were half-brothers. However, Carlon was born during his mother’s marriage to another man, making that husband his presumptive father under the Utah Uniform Parentage Act (UUPA).

Key Legal Issues

The case presented two main issues: (1) whether the UUPA was the exclusive method for establishing parent-child relationships for intestate succession purposes, and (2) whether the one-set-of-parents rule from adoption law applied to prevent inheritance from multiple fathers.

Court’s Analysis and Holding

The Court of Appeals affirmed the district court’s ruling in favor of Carlon. Under Utah Code section 75-2-114(1), “an individual is the child of the individual’s natural parents, regardless of their marital status.” The statute states that parent-child relationships “may be established” under the UUPA, not that they must be. The court emphasized that the UUPA itself provides that parent-child relationships established under it apply “except as otherwise specifically provided by other law,” making the Probate Code controlling for inheritance purposes. Regarding the one-set-of-parents rule, the court noted this principle derives from adoption statutes and found no statutory language extending it beyond the adoption context to situations involving different biological and presumptive fathers.

Practice Implications

This decision demonstrates the importance of analyzing which statutory framework governs specific legal questions. While the outcome may seem unusual—allowing inheritance from multiple fathers—the court emphasized it was bound by the plain language of Utah’s Probate Code. The court noted that other states have adopted revised Uniform Probate Code provisions that would prevent this result, but Utah has not yet done so. Practitioners should carefully examine whether parentage presumptions under the UUPA control inheritance rights or whether the more permissive Probate Code standards apply.
