RE: Karen Callahan v. Joseph Nelson, C.A. No. 2024-1099-BWD

Dear Counsel:

This letter opinion resolves exceptions to a partition trustee’s report recommending a procedure to govern the private auction of a Goldendoodle named Tucker. The partition trustee’s report recommends a single-submission blind-bid auction. The Court adopts the partition trustee’s recommendation, for the reasons explained below.

C.A. No. 2024-1099-BWD January 28, 2026 Page 2 of 12

I. PROCEDURAL HISTORY As the Court has now described in three written rulings, this action concerns a petition to partition a Goldendoodle named Tucker. Callahan v. Nelson, 2025 WL 3181943 (Del. Ch. Nov. 14, 2025) [hereinafter Op.]. Karen Callahan (“Petitioner”) and Joseph Nelson (“Respondent”) acquired Tucker while they were dating. Id. at *2. Petitioner and Respondent ended their relationship in May 2022, and Petitioner has not seen Tucker since. Id. The Delaware Superior Court previously determined that Petitioner and Respondent have joint ownership interests in Tucker. Id. at *2 n.4.

On October 28, 2024, Petitioner initiated this action through the filing of a Petition for Partition (the “Petition”), seeking an order for partition of Tucker. Dkt. 1. Respondent moved to dismiss the Petition, arguing that the Court should refuse to order the “unprecedented” relief of partitioning a companion animal. Dkts. 4, 7. On May 7, 2025, the Court issued a Memorandum Opinion Denying Motion to Dismiss Petition for Partition (the “Memorandum Opinion”), denying Respondent’s motion to dismiss. Callahan v. Nelson, 2025 WL 1326719 (Del. Ch. May 7, 2025) [hereinafter Mem. Op.]. The Memorandum Opinion explained that although Delaware’s partition statute governs only the right to partition real property, courts of equity also have historically upheld the right of a tenant in common to seek a

C.A. No. 2024-1099-BWD January 28, 2026 Page 3 of 12

partition of personal property. Id. at *2. Because the law views a pet as personal property, a jointly owned pet must be subject to a partition remedy. Id. The Memorandum Opinion reasoned that, without an equitable partition remedy, the parties might remain trapped in joint ownership of their pet indefinitely, notwithstanding their mutual desire to part ways. Id. at *3. The Memorandum Opinion concluded that “crafting a fair and orderly process to resolve the rights of these co-owners so they can move on is in the best interests of everyone involved, including Tucker.” Id. Although the Court did not decide the appropriate partition procedure at that time, the Memorandum Opinion stated that “[t]he right procedure w[ould] result in one party owning Tucker and the other receiving a monetary award.” Id. at *1.

The Court directed the parties to meet and confer on an appropriate partition procedure, but the parties were unable to reach agreement. Op. at *3. Petitioner advocated for an auction in which the party willing to pay the highest price to the other will acquire Tucker. Id. Respondent argued that the Court should award ownership based on an evaluation of Tucker’s best interests. Id. On November 7, the Court held an evidentiary hearing to provide the parties an opportunity to supplement their legal arguments with evidence to support their positions on the appropriate partition procedure. Id.

On November 14, the Court issued an Opinion on Partition of Companion Animal (the “Opinion”). Id. at *1. The Opinion acknowledged that although Delaware law recognizes a common law right to partition personal property, the procedure for partitioning a companion animal is “uncharted.” Id. at *4. The Opinion considered several potential partition procedures. Id. at *4. It noted that under Delaware’s real property partition statute, the default procedure is a physical, in kind, division of the property. Id. That procedure would not work for a living being. Id. The Opinion further considered that under the partition statute and at common law, the alternative procedure for partition is a sale at “public vendue” intended to put the property to its highest and best use. Id. The Opinion rejected the concept of a public auction because the parties attach far more value to Tucker than would any member of the public. Id. at *4 n.19. The Opinion also considered alternative partition procedures that the parties had not raised. Id. It noted that an appraisal of Tucker’s fair market value is unlikely to be helpful given the subjective value each party places on Tucker. Id. It also rejected the concept of a “partition in time,” which could look like a joint custody arrangement, because the parties no longer wish to be bound to one another and such an arrangement is unlikely to be successful. Id.

The Opinion concluded, instead, that when partitioning a companion animal, “our preexisting common law governing property ownership provides the right place to start the analysis.” Id. at *5. The Opinion therefore “beg[a]n with a presumption that partition of a companion animal should occur through an auction designed to maximize value for the co-owners.” Id. The Opinion held that such a “presumption may be rebutted, however, because a court of equity has broad latitude to balance various interests and fashion remedies as appropriate.” Id. The Opinion recognized that

[d]ogs are property, but they are not furniture; they are living, sentient beings with value that transcends economics. If the equities of a particular case require awarding ownership to one owner over another—particularly to prevent harm to a sentient being—a court of equity is bound to consider those facts as well.

Id.

Turning to the specifics of this case, the Opinion decided that the facts here “do not support deviating from the common law presumption of a value-maximizing auction,” explaining that “[i]t is clear from the evidence that both Petitioner and Respondent care deeply for Tucker, and that either one would make a suitable pet owner.” Id. at *6. The Court therefore appointed a trustee (the “Partition Trustee”) to conduct a private auction to determine Tucker’s ownership. Order Appointing Partition Trustee, Dkt. 29. The Court did not decide how the auction would work

and instead directed the parties to “meet and confer with the Partition Trustee on procedures to govern the auction.” Id. at 2.
