ORDER DENYING APPLICATION FOR CERTIFICATION OF INTERLOCUTORY APPEAL AND MOTION FOR A STAY PENDING APPEAL

WHEREAS:

A. Joseph Nelson (“Respondent”) has applied for certification of

interlocutory appeal (the “Application”) of this Court’s November 14, 2025 Opinion

on Partition of Companion Animal (the “Opinion”) and Order Appointing Partition

Trustee. Resp’t’s Appl. for Certification of Interlocutory Appeal [hereinafter Appl.],

Dkt. 32.

B. 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 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.

C. 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.

D. 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 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,

2 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.

E. 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. On

June 20, Petitioner filed an opening brief advocating for a “transparent auction”

through which the party willing to pay the highest price to the other will acquire

Tucker. Id. On July 21, Respondent filed an answering brief in opposition, arguing

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.

F. One week later, on November 14, the Court issued the Opinion. The

Opinion acknowledged that although Delaware law recognizes a common law right

to partition personal property, “[t]his Court has never partitioned a pet, so the

procedure for doing so is uncharted.” Id. at *4. The Opinion explained, however,

that the Court of Chancery has broad latitude to exercise its equitable powers to craft

an appropriate remedy. Id.

3 G. 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. at *1. That procedure

would not work for a living being. Id. at *4. 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.

H. 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.

I. 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

4 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.

J. 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.

K. The Court therefore appointed a 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 will work. Instead, in its Order

Appointing Partition Trustee, the Court directed the parties to “meet and confer with

the Partition Trustee on procedures to govern the auction.” Id. at 2. The Court

instructed that “[i]f the parties cannot agree on such procedures, the Partition Trustee

shall file a report with the Court recommending procedures to govern the auction,

and the parties may file written responses to the Partition Trustee’s report within

fourteen days of the report.” Id.

5 L. Respondent filed the Application on November 21. Separately,

Respondent filed a Motion for a Stay Pending Appeal (the “Motion”). Resp’t’s Mot.

for a Stay Pending Appeal [hereinafter Mot.], Dkt. 33.
