Can unwed fathers amend paternity petitions after mothers consent to adoption? Donjuan v. McDermott Explained

2011 UT 72
No. 20100012

Affirmed

Summary

An unwed father filed a paternity petition but failed to include the sworn affidavit required by Utah Code section 78B-6-121. After the mother executed her consent to adoption, the father amended his petition to include the required affidavit and argued it should relate back to the original filing date under rule 15.

Analysis

In Donjuan v. McDermott, the Utah Supreme Court addressed whether an unwed father can use civil procedure rules to cure defects in his paternity petition after a mother has consented to adoption. The court’s holding clarifies the strict compliance requirements for unwed fathers seeking to preserve their parental rights in adoption proceedings.

Background and Facts

Marco Donjuan and Gabrielle McDermott had a relationship that resulted in pregnancy. Before the child’s birth, Donjuan expressed interest in raising the child and initiated paternity proceedings in Georgia. When McDermott moved to Utah and planned to place the child for adoption, Donjuan filed a paternity petition in Utah requesting custody and stating his willingness to pay child support. However, he failed to include the sworn affidavit required by Utah Code section 78B-6-121. After McDermott executed her consent to adoption on August 3, 2009, Donjuan amended his petition to include the required affidavit on August 11, 2009.

Key Legal Issues

The central issue was whether Rule 15 of the Utah Rules of Civil Procedure allows amendment of a paternity petition to include the sworn affidavit required by section 78B-6-121 after the mother has executed her consent to adoption, and whether such amendment relates back to the original filing date.

Court’s Analysis and Holding

The court held that the relation back doctrine of Rule 15 does not apply to cure the failure to include required affidavits in adoption proceedings. Utah Code section 78B-6-121 requires strict compliance with all statutory requirements, including filing the sworn affidavit “prior to the time the mother executes her consent for adoption.” The court emphasized that general civil procedure rules cannot obviate explicit statutory requirements. Because Donjuan failed to file the affidavit until after McDermott’s consent execution, his ability to fulfill the statutory requirements had expired.

Practice Implications

This decision reinforces that adoption statutes requiring strict compliance cannot be circumvented through procedural rules. Practitioners representing unwed fathers must ensure all statutory requirements, including sworn affidavits, are included in the initial paternity petition. The court also declined to address constitutional challenges that were not preserved in the trial court, emphasizing the importance of proper preservation of error in appellate practice.

Outcome

Affirmed

Holding

The relation back doctrine of rule 15 does not allow a father to amend his paternity petition to include the sworn affidavit required by Utah Code section 78B-6-121 after the mother has executed her consent to adoption because the statute requires strict compliance with timing requirements.

Standard of Review

Correctness for questions of law regarding the applicability of rule 15 of the Utah Rules of Civil Procedure to adoption proceedings

Practice Tip

In adoption proceedings involving unwed fathers, ensure all statutory requirements including sworn affidavits are filed with the initial petition, as amendment after the mother’s consent execution will be untimely regardless of civil procedure rules.
