FIFTH DISTRICT ______________________________________________________________________________

SOPHIA CHU, ) Appeal from the ) Circuit Court of Petitioner-Appellee, ) St. Clair County. ) v. ) No. 25-FA-279 ) WILLIAM L. NANNA, ) Honorable ) Alana I. Mejias, Respondent-Appellant. ) Judge, presiding. ______________________________________________________________________________

JUSTICE SHOLAR delivered the judgment of the court. Presiding Justice Cates and Justice Barberis concurred in the judgment.

ORDER

¶1 Held: The circuit court erred by denying respondent’s motion to dismiss and registering petitioner’s Japanese divorce decree as a foreign judgment because the Foreign Judgments Act does not include judgments of foreign countries within its definition of “foreign judgments.”

¶2 The respondent, William L. Nanna, appeals the September 30, 2025, order of the circuit

court of St. Clair County denying his motion to dismiss and granting the petitioner, Sophia Chu’s,

petition to register a foreign judgment. On appeal, Nanna argues that the circuit court erred by

granting Chu’s petition to register the foreign judgment because the trial court lacked personal

jurisdiction over Nanna, and the Uniform Enforcement of Foreign Judgments Act (Foreign

Judgments Act) (735 ILCS 5/12-652 (West 2024)) does not include judgments of foreign countries

within its definition of “foreign judgments.” For the reasons that follow, we reverse the circuit

1 court’s September 30, 2025, order denying Nanna’s motion to dismiss and granting Chu’s petition

to register the foreign judgment.

¶3 I. BACKGROUND

¶4 The parties married on May 30, 2011, in Okinawa, Japan. Three children were born of the

marriage. In November 2020 the parties separated and Chu subsequently filed for divorce in Japan.

On December 16, 2021, a “Conciliation Record (Successful Conciliation)” was entered in the

Japanese court. The conciliation terms included, inter alia, that Nanna was obligated to pay (1) a

lump sum of $200,000 to Chu by September 15, 2022; (2) $2,000 each month as “post-divorce

living support” until May 31, 2025, or until Nanna retired from the military; (3) $30,000 of

attorney fees incurred by Chu in Texas; and (4) monthly child support. The conciliation terms

granted sole custody of the children to Chu subject to Nanna’s visitation rights.

¶5 On May 29, 2025, Chu filed a petition to register the foreign judgment in the circuit court

of St. Clair County. Her petition sought to register the Japanese judgment “in accordance with 735

ILCS 5/12-652.” Chu’s petition attached an authenticated copy of the judgment and alleged that

since the entry of the judgment, Nanna relocated his employment to Illinois. Her petition further

alleged that Nanna maintained a bank account at Navy Federal Credit Union in Illinois.

¶6 On July 22, 2025, counsel for Nanna filed his entry of special and limited appearance for

the “sole purpose of contesting this Court’s personal jurisdiction over [Nanna].” On August 6,

2025, Nanna filed a motion to dismiss Chu’s petition to register a foreign judgment. In his motion

to dismiss, Nanna argued (1) that the circuit court lacked personal jurisdiction because he was not

personally served, and Chu did not demonstrate Nanna had the necessary “minimum contacts”

under Illinois's long-arm statute; (2) that the registration of the Japanese judgment was barred by

2 res judicata, because Chu previously attempted to register the judgment in Missouri; 1 and (3) that

the definition of “foreign judgment” under the Foreign Judgments Act does not extend to

judgments of other countries.

¶7 The circuit court heard Nanna’s motion to dismiss on September 30, 2025. Nanna stated

that his motion to dismiss based on res judicata had become moot because the Missouri court of

appeals reversed the circuit court’s decision to deny his motion to dismiss in Missouri. Nanna

reiterated the arguments made in his motion to dismiss based on lack of personal jurisdiction and

that the Foreign Judgments Act does not apply to judgments of other countries. With respect to the

Foreign Judgments Act, Nanna argued that the purpose of the Foreign Judgments Act was to

provide a summary procedure to enforce judgments from courts of the United States, not other

countries.

¶8 In response, Chu alleged that Nanna failed to pay the lump sum of $200,000, attorney fees

in the amount of $30,000, and child support as ordered by the Japanese judgment. Chu clarified

that she initially registered the judgment in Missouri and attempted to levy a garnishment on

Nanna’s bank account, but that bank was located in Illinois, not Missouri. Chu argued that pursuant

to the Foreign Judgments Act, she was not required to serve a summons on Nanna, but rather, the

court was tasked with notifying a respondent via mail. Chu further argued that Illinois law

permitted a foreign judgment from a different country to be registered in Illinois, citing La Societe

Anonyme Goro v. Conveyor Accessories, Inc., 286 Ill. App. 3d 867 (1997). In reply, Nanna

clarified that he never resided in Illinois and that he retired from the Air Force in June of 2025.

1 Chu filed a petition to register the foreign judgment in the circuit court of St. Charles County, Missouri, which was pending on appeal at the time Nanna filed his motion to dismiss. We take judicial notice that on September 16, 2023, the Missouri Court of Appeals, Eastern District, dismissed Chu’s petition based on her failure to file a verified petition. As such, Nanna withdrew his argument for res judicata at the September 30, 2025, motion hearing. 3 ¶9 In its ruling on the motion to dismiss, the circuit court made an oral pronouncement and

opined that the foreign judgment could be registered. The court stated that the issues raised by

Nanna in his motion to dismiss could be raised and addressed when Chu sought contempt or

garnishment proceedings. The court clarified it did not find that the court had personal jurisdiction

over Nanna, but rather that Chu met all requirements to register the foreign judgment.

¶ 10 On September 30, 2025, the circuit court entered a written order stating “Respondent’s

motion to dismiss is called, heard and denied. The Judgment requested to be registered on May 29,

2025[,] by Petitioner is deemed to be registered.” On October 29, 2025, Nanna filed a timely notice

of appeal.

¶ 11 II. ANALYSIS

¶ 12 On appeal, Nanna argues that the circuit court erred by denying his motion to dismiss and

by registering Chu’s foreign judgment. Specifically, Nanna argues that the circuit court erred by

granting Chu’s petition to register the foreign judgment because (1) the trial court lacked personal

jurisdiction over Nanna and (2) the Foreign Judgments Act does not include judgments of foreign

countries within its definition of “foreign judgments.” For the reasons that follow, we agree that

the Foreign Judgments Act does not include judgments of foreign countries within its definition

of “foreign judgments.”
