Background

After the sudden death of a child’s mother, the child’s maternal grandmother and brother petitioned for guardianship and sought emergency relief. They alleged that the child feared the father because of a history of domestic violence, had not visited with him for several years, and could suffer a severe mental-health crisis if placed with him.

Following a priority hearing, the Family Court entered an interim order granting the petitioners guardianship pending a full hearing. The court found that immediate placement with the father was not in the child’s best interest given the lack of a relationship and the child’s fear, and it directed the child to work with a therapeutic-visitation counselor toward visitation with the father. The self-represented father appealed and sought an emergency stay, but he did not timely seek Family Court certification of the interlocutory appeal under Delaware Supreme Court Rule 42.

The Court’s Holding

The Delaware Supreme Court dismissed the appeal. The father’s application for certification was filed after Rule 42’s ten-day deadline, the Family Court declined to extend that deadline, and the Supreme Court concluded that the father had not shown good cause for the late filing.

The court also held that interlocutory review would not have been warranted even if the application had been timely. No exceptional circumstances justified immediate review, none of the Rule 42(b)(iii) factors had been established, and the potential benefits did not outweigh the inefficiency, disruption, and probable costs of an interlocutory appeal. The emergency-stay motion was therefore moot, although the court allowed the filing fee to be applied to a future appeal from the Family Court’s final guardianship order.

Key Takeaways

  • An application for certification of an interlocutory appeal must be filed in the trial court within Rule 42’s ten-day deadline unless the trial court extends the deadline for good cause.
  • Self-represented status did not establish good cause for the father’s untimely certification request.
  • An interim guardianship arrangement pending therapeutic visitation and a full merits hearing did not present the exceptional circumstances required for interlocutory review.

Why It Matters

The order underscores that Delaware’s interlocutory-review procedure is strictly limited, including in urgent family-law disputes. A litigant must timely seek certification and independently demonstrate that immediate appellate review satisfies Rule 42’s demanding standards.

The decision also favors allowing the Family Court to complete the guardianship proceeding before appellate intervention, while preserving the father’s ability to appeal after entry of a final order.
