Fourteenth Court of Appeals

NO. 14-19-00689-CV

CELINA HELLMUND, Appellant

V.

GABRIEL CASTELLÓ, Appellee

On Appeal from the 129th District Court

Harris County, Texas

Trial Court Cause No. 2019-20955

M E M O R A N D U M O P I N I O N

Appellant Celina Hellmund appeals an order granting appellee Gabriel 

Castelló’s special appearance. Hellmund raises two issues. First, Hellmund

contends the trial court erred in granting Castelló’s special appearance because a 

Texas court has personal jurisdiction over him under specific jurisdiction principles. 

Second, Hellmund contends the trial court abused its discretion in striking her 

supplemental evidence filed three days before the hearing on the ground that it was 

untimely. 
2

We conclude that the trial court did not abuse its discretion by striking 

Hellmund’s supplemental evidence because it was untimely, and we overrule her 

second issue. As to Hellmund’s first issue, for the reasons explained below, we 

conclude that she has not shown the trial court erred in granting Castelló’s special 

appearance on specific jurisdiction grounds. Therefore, we overrule Hellmund’s 

first issue.

We affirm the trial court’s order granting Castelló’s special appearance.

Background

Hellmund, a resident of Switzerland, sued Castelló, also a resident of 

Switzerland, and Allegra LLC, a Texas limited liability company, in Harris County 

District Court. Purportedly, both Hellmund and Castelló are members and managers 

of Allegra. In her original petition, Hellmund alleged under the “jurisdiction” 

paragraph that the court “has jurisdiction to provide all relief requested,” and that 

the parties have contractually agreed that mandatory venue lies in Texas courts. 

Hellmund asserted claims against Castelló for breach of an oral contract, fraud, 

fraudulent inducement, and breach of fiduciary duties to Hellmund and Allegra.

1

Hellmund alleged the following facts:

• Hellmund and Castelló are both residents of Switzerland.

• Hellmund and Castelló executed a purchase agreement for a luxury 

condominium unit in Houston. 

1 Hellmund purported to bring claims both individually and derivatively on Allegra’s 

behalf, and she requested the court to treat her derivative claims as a “direct action” for her own 

benefit. See Tex. Bus. Orgs. Code § 101.463(c). Allegra specially excepted to Hellmund’s right 

to bring a derivative action. The issue of Hellmund’s right or standing to assert Allegra’s claims

derivatively, if any, is not before us in this appeal, however. The issue is whether personal 

jurisdiction exists over Castelló as to any claims, whether asserted by Hellmund, Allegra, or both.
3

• Castelló promised Hellmund that he would solely fund the purchase of the 

unit for her and that he would pay for all renovations, furnishings, upkeep, 

and taxes for the unit. Renovations on the unit began, and Hellmund and 

Castelló met with interior decorators and designers.

• Hellmund and Castelló were married in September 2016. 

• Hellmund and Castelló then formed Allegra in February 2017. Each 

owned a fifty percent interest in Allegra; Allegra was formed for the 

purpose of purchasing and managing real property. 

• In June 2018, “Castelló and Hellmund, through Allegra, LLC[,] closed on 

the purchase of its sole asset,” the condominium unit. 

• The condominium unit “was intended for Hellmund to retain a place in 

Houston, Texas – where she had resided since 1989 – and for both 

Hellmund and Castelló to use and enjoy during their stays in the USA.”

Castelló promised to gift the condominium unit to Hellmund as her 

separate property.

• At closing, Castelló invested $400,000 capital in Allegra and paid 

$300,000 for costs. However, soon after closing, Castelló refused to 

approve or pay for any previously approved work on the unit.

• In November 2018, Castelló informed Hellmund that he wished to divorce 

and that he was moving out of their marital residence in Switzerland. He 

made no further financial contributions to Allegra nor did he provide any 

further financial contributions to the condominium unit.

In support of her breach of contract claim, Hellmund alleged that Castelló 

breached his oral promises to pay (through Allegra) for all costs related to the 

purchase and that he would gift the unit to Hellmund as her separate property.
4

In support of the breach of fiduciary duty claim, Hellmund alleged that 

Castelló owed fiduciary duties to Allegra and Hellmund; and that he breached those

fiduciary duties by: (1) unilaterally making decisions regarding Allegra’s 

operations; (2) failing to make additional capital contributions; (3) gross 

mismanagement; (4) misappropriating funds and other assets; (5) failing to disclose 

information about matters affecting Allegra; and (6) denying Hellmund access to 

financial information as requested. 

In support of her fraud and fraudulent inducement claims, Hellmund alleged 

that Castelló fraudulently induced her into forming Allegra to purchase the 

condominium unit by promising to pay for the unit and gift it to her.

Castelló filed a special appearance and attached a sworn declaration, in which 

he averred among other things that he has never resided in Houston, that he is a 

resident of Switzerland, and that he has not entered into any venue agreements with 

Hellmund. Castelló asserted that his declaration rebutted the vague jurisdictional

allegation in Hellmund’s petition. Castelló further urged in his special appearance 

that his limited contacts with Texas, including a few trips to Houston and being a 

member of a Texas LLC, were not continuous and substantial enough to subject him 

to general jurisdiction in Texas. Castelló contended that his only connection to 

Texas is his membership in Allegra; and that his partial ownership of Allegra—an 

entity that owns property in Texas—is insufficient to call him into a Texas court 

because he never availed himself of the privilege of conducting business in Texas

and because his Texas contacts are not substantially related to the operative facts of 

the litigation. According to Castelló, Allegra was conceived by Hellmund’s tax 

attorney, and Hellmund unilaterally directed all of Allegra’s activities without his 

input or consent. Finally, Castelló contended that exercising personal jurisdiction 

over him in Texas would offend traditional notions of fair play and substantial 
5

justice. He further stated that he and Hellmund were involved in divorce 

proceedings in Switzerland that could impact this lawsuit. He set a hearing on his 

special appearance for July 8, 2019.

Hellmund filed a response. She contended that Castelló was subject to 

specific jurisdiction in Texas because: (1) he executed a contract for the purchase 

of real property in his individual capacity; (2) he and Hellmund formed a Texas 

limited liability company, Allegra, subject to the protections, provisions, and 

benefits of Texas law; (3) his contacts with Texas were directly connected to 

Hellmund’s lawsuit; and (4) personal jurisdiction over Castelló does not offend 

traditional notions of fair play and substantial justice. Hellmund attached 

documentary evidence in support of her response. The documents, however, either 

were not authenticated or not translated into English from a foreign language. 

Hellmund did not attach any affidavit or sworn declaration in support of her 

jurisdictional allegations.

The special appearance hearing was reset to July 22. Seven days before the 

hearing, Castelló filed supplemental evidence. He filed an amended declaration, 

which restated the facts from his original declaration but added that the property at 

issue was included in a proposed divorce settlement with Hellmund in Switzerland. 

He attached a translated copy of the proposed settlement, which provided that he 

would sell his interest in Allegra to Hellmund and transfer his equity in Allegra to 

her sole ownership. Castelló also attached a sworn declaration from his Swiss 

divorce counsel, who stated among other things that Swiss law governs the parties’ 

divorce and that the Swiss court will have the opportunity to adjudicate the 

disposition of the property acquired during the marriage and owned by Allegra. 

Three days before the hearing, Hellmund filed a supplemental response, 

attaching sworn declarations by her and her Swiss divorce counsel. However, at the 
6

July 22 hearing, Castelló’s counsel objected to Hellmund’s supplemental response 

and evidence because it was filed less than seven days before the hearing and was 

therefore untimely. See Tex. R. Civ. P. 120a(3). The trial judge informed 

Hellmund’s counsel that he could not consider the late declarations and asked what 

Hellmund wanted to do. Counsel decided to proceed with the hearing relying only 

on the initial response. Later during the hearing, Castelló’s counsel also objected to 

the evidence attached to Hellmund’s initial response because the exhibits were not 

authenticated or properly proven. The trial court did not rule on the objection during 

the hearing.

Two days after the hearing, Hellmund filed a motion to conduct jurisdictional 

discovery and for a new hearing. 

On July 31, the trial court granted Castelló’s special appearance and dismissed 

all claims asserted by Hellmund without prejudice for lack of personal jurisdiction. 

The trial court also struck all of Hellmund’s evidence submitted with both her initial 

and supplemental responses:

(1)The evidence that Plaintiff filed in support of her Supplemental 

Response – the Declarations of Margherita Bortolani and Celina 

Hellmund and attachments thereto – is STRICKEN as untimely 

under Texas Rule of Civil Procedure 120a(3).

(2)The evidence that Plaintiff filed in support of [her] response, 

Exhibits 1-9, is STRICKEN as inadmissible evidence because it is 

hearsay and Plaintiff failed to lay the proper foundation, authenticate 

the documents, and provide a certified translation of Exhibit 1[.]

Hellmund timely appealed.

Analysis

Hellmund presents two issues: (1) whether the trial court erred by granting 

Castelló’s special appearance; and (2) whether the trial court erred by striking her 
7

supplemental evidence as untimely filed. She does not challenge the trial court’s 

order striking the evidence attached to her initial response. We first clarify the 

universe of evidence before us, then proceed to evaluate whether the court erred in 

granting the special appearance.

A. The trial court did not abuse its discretion in striking Hellmund’s 

supplemental evidence.

Whether to admit or exclude evidence is within the trial court’s sound 

discretion. Nat’l Liability & Fire Ins. Co. v. Allen, 15 S.W.3d 525, 527 (Tex. 2000); 

Gonzalez v. Champion Techs., Inc., 384 S.W.3d 462, 467 (Tex. App.—Houston 

[14th Dist.] 2012, no pet.). Thus, on appeal, we review a trial court’s evidentiary 

decisions for an abuse of discretion. Nat’l Liability & Fire Ins. Co., 15 S.W.3d at 

527; see also Gonzalez, 384 S.W.3d at 467. 

Texas Rule of Civil Procedure 120a requires parties to serve affidavits in 

support of or in opposition to a special appearance seven days before the hearing:

The court shall determine the special appearance on the basis of the 

pleadings, any stipulations made by and between the parties, such 

affidavits and attachments as may be filed by the parties, the results of 

discovery processes, and any oral testimony. The affidavits, if any, 

shall be served at least seven days before the hearing, shall be made on 

personal knowledge, shall set forth specific facts as would be 

admissible in evidence, and shall show affirmatively that the affiant is 

competent to testify.

Tex. R. Civ. P. 120a(3) (emphasis added). The rule further provides that, if it appears 

from a party’s affidavit that she cannot present facts sufficient to justify opposition 

to a special appearance, the trial court “may order a continuance to permit affidavits 

to be obtained or depositions to be taken or discovery to be had or may make such 

other order as is just.” Tex. R. Civ. P. 120a(3).
8

Hellmund did not comply with this rule. She does not dispute that she filed 

her supplemental declarations less than seven days before the hearing. She did not 

timely seek a continuance pursuant to Rule 120a, and to the extent the trial court’s 

order implicitly denied Hellmund’s post-hearing motion for continuance, she does 

not challenge the denial of a continuance on appeal. Moreover, during the special 

appearance hearing she informed the trial court that she did not need the 

supplemental evidence. Based on our record, we cannot say the trial court abused 

its discretion. Cf. BMC Software Belgium, N.V. v. Marchand, 83 S.W.3d 789, 800-

01 (Tex. 2002); Munz v. Schreiber, No. 14-17-00687-CV, 2019 WL 1768590, at 

*10-11 (Tex. App.—Houston [14th Dist.] Apr. 23, 2019, no pet.) (mem. op.).

We overrule Hellmund’s second issue. 

B. The trial court did not err in granting Castelló’s special appearance.

1. Personal jurisdiction framework and standard of review

Texas courts may assert in personam jurisdiction over a nonresident if (1) the 

Texas long-arm statute authorizes the exercise of jurisdiction, and (2) the exercise 

of jurisdiction is consistent with federal and state constitutional due-process 

guarantees. Moki Mac River Expeditions v. Drugg, 221 S.W.3d 569, 574 (Tex. 

2007). The Texas long-arm statute authorizes Texas courts to exercise jurisdiction 

over a nonresident defendant who “does business” in the state. See Tex. Civ. Prac. 

& Rem. Code §§ 17.042, 17.043. The Legislature has described a non-exclusive list 

of acts that may constitute “doing business” in this state, such as contracting with a 

Texas resident and either party is to perform the contract in whole or in part in Texas, 

or committing a tort in whole or in part in Texas. See id. §§ 17.042(1), (2). 

Hellmund does not argue on appeal that Castelló did business in Texas under 

subsections 17.042(1) or (2), and her pleadings are likely inadequate to support 

jurisdiction under those provisions. She alleged and argues on appeal that Castelló 
9

did business in Texas because he is a member and manager of a Texas LLC and that 

jurisdiction is authorized based solely on that fact. 

The exercise of jurisdiction is consistent with federal and state constitutional 

due-process guarantees when (1) the nonresident defendant has minimum contacts 

with the forum state and (2) the assertion of jurisdiction complies with traditional 

notions of fair play and substantial justice. Int’l Shoe Co. v. Washington, 326 U.S. 

310, 316 (1945); Peters v. Top Gun Exec. Grp., 396 S.W.3d 57, 62 (Tex. App.—

Houston [14th Dist.] 2013, no pet.). Minimum contacts are sufficient for personal 

jurisdiction when the nonresident defendant purposefully avails itself of the privilege 

of conducting activities within the forum state, thus invoking the benefits and 

protections of its laws. M & F Worldwide Corp. v. Pepsi-Cola Metro. Bottling Co., 

512 S.W.3d 878, 886 (Tex. 2017). A nonresident defendant’s purposeful contacts 

with a forum state can give rise to either general or specific jurisdiction. Id. at 885. 

Here, Hellmund invokes only specific jurisdiction. In analyzing specific 

jurisdiction, in addition to the “purposeful availment” question, we also focus on the 

relationship among the defendant, the forum, and the particular litigation at hand. 

See id. at 886; Spir Star AG v. Kimich, 310 S.W.3d 868, 873 (Tex. 2010); Moki Mac, 

221 S.W.3d at 575-76. As the Supreme Court of Texas has clarified, specific 

jurisdiction arises when: (1) the nonresident creates minimum contacts with Texas 

by purposefully availing himself of the privilege of conducting activities here; and 

(2) a “substantial connection” exists between those purposeful contacts and the 

operative facts of the litigation. Moki Mac, 221 S.W.3d at 575-76, 585. If both of 

these circumstances are satisfied, then a Texas court may exercise personal 

jurisdiction over a nonresident defendant so long as doing so comports with 

traditional notions of fair play and substantial justice. Kelly v. Gen. Interior Constr., 

Inc., 301 S.W.3d 653, 658 (Tex. 2010).
10

In a challenge to personal jurisdiction, the plaintiff and the defendant bear 

shifting burdens of proof. Id. at 658. The plaintiff bears the initial burden of 

pleading sufficient facts to bring a nonresident defendant within the reach of the 

Texas long-arm statute. Id.; see Tex. Civ. Prac. & Rem. Code § 17.042; Perna v. 

Hogan, 162 S.W.3d 648, 653 (Tex. App.—Houston [14th Dist.] 2005, no pet.). But 

if the plaintiff fails to plead facts bringing the defendant within reach of the Texas 

long-arm statute, the defendant need only prove that he does not live in Texas to 

negate jurisdiction. Kelly, 301 S.W.3d at 658.

If the plaintiff meets its initial burden, the burden then shifts to the defendant 

to negate all bases of personal jurisdiction alleged by the plaintiff. Id.. “Because 

the plaintiff defines the scope and nature of the lawsuit, the defendant’s 

corresponding burden to negate jurisdiction is tied to the allegations in the plaintiff’s 

pleading.” Id. A defendant can negate jurisdiction on either a factual or a legal 

basis. Id. at 659. “Factually, the defendant can present evidence that it has no 

contacts with Texas, effectively disproving the plaintiff’s allegations.” Id. Or the 

defendant can show that even if the plaintiff’s alleged facts are true, the evidence is 

legally insufficient to establish jurisdiction. Id. If the defendant meets its burden of 

negating all alleged bases of personal jurisdiction, then the plaintiff must respond 

with evidence “establishing the requisite link with Texas.” See id. at 660.

We review de novo a trial court’s decision regarding a special appearance. 

See M & F Worldwide, 512 S.W.3d at 885. 

2. Application

The key jurisdictional fact pleaded by Hellmund is her allegation that Castelló 

is a member of a Texas LLC, which Castelló admits. Although this activity is not 

one listed in section 17.042, we will assume for argument’s sake that a nonresident’s 

membership in a Texas LLC constitutes “doing business” in Texas sufficient to 
11

satisfy the purposeful-availment test for minimum contacts purposes.2 Presuming 

that element of specific jurisdiction is met, to reverse the order granting Castelló’s 

special appearance Hellmund must show on appeal that (1) a “substantial 

connection” exists between Castelló’s LLC membership and the operative facts of 

the litigation, and (2) the assertion of jurisdiction would comply with traditional 

notions of fair play and substantial justice. If the record supports an implicit finding

or conclusion against Hellmund on either or both of these factors, then the trial court

did not err in granting the special appearance. See Kelly, 301 S.W.3d at 659; Voltaix, 

LLC v. Ajongwen, 406 S.W.3d 235, 241-43 (Tex. App.—Dallas 2013, no pet.).

Generally speaking, an appellant must attack all independent bases or grounds 

that fully support a complained-of ruling or judgment. E.g., Britton v. Tex. Dep’t of 

Crim. Justice, 95 S.W.3d 676, 681 (Tex. App.—Houston [1st Dist.] 2002, no pet.); 

see also Lathrop v. Personalysis Corp., No. 14-06-00074-CV, 2006 WL 3072072, 

at *5 (Tex. App.—Houston [14th Dist.] Oct. 31, 2006, no pet.) (mem. op.) (applying 

Britton to an appeal of the denial of a special appearance). This premise flows from 

the well-recognized precept that we may not reverse a trial court’s judgment on 

unassigned error. E.g., Pike v. Tex. EMC Mgmt., LLC, No. 17-0557, —S.W.3d—, 

2020 WL 3405812, at *13 (Tex. June 19, 2020) (“A court of appeals may not reverse 

a trial court judgment on a ground not raised.”); Walling v. Metcalfe, 863 S.W.2d 

56, 58 (Tex. 1993) (“We have repeatedly held that courts of appeals may not reverse 

the judgment of a trial court for a reason not raised in a point of error.”). If the 

2

In her opening brief, Hellmund also argued that Castelló is subject to personal jurisdiction 

in Texas because she alleged in her petition that she and Castelló “have contractually agreed that 

mandatory venue shall be in the state courts of Texas,” and that Castelló did not deny the 

allegation. However, in her reply brief, Hellmund acknowledges that Castelló did, in fact, deny 

the allegation, and Hellmund abandoned the argument as a ground for reversing the trial court’s 

ruling. 
12

appellant fails to challenge all grounds that may have supported the judgment, then 

generally we must affirm the ruling. See Britton, 95 S.W.3d at 681. 

In her appellate brief, Hellmund challenges only the purposeful-availment 

prong of the specific jurisdiction inquiry. Her brief contains no argument or 

authority addressing the “substantial connection” issue or asserting substantively 

that exercising jurisdiction over Castelló would comport with traditional notions of 

fair play and substantial justice. See Tex. R. App. P. 38.1(i); Pike, 2020 WL 

3405812, at *13. We have independently reviewed the record and conclude that the 

trial court reasonably could have determined that exercising personal jurisdiction 

over Castelló for the claims alleged would offend traditional notions of fair play and 

substantial justice. Though the exercise of jurisdiction rarely fails the test of fair 

play and substantial justice when a defendant has established minimum contacts with 

the forum state,

3 we think this case presents just such an exception based on the 

evidence before the trial court. 

To avoid being haled into a foreign court, a nonresident defendant must 

present “a compelling case that the presence of some consideration would render 

jurisdiction unreasonable.” Burger King Corp. v. Rudzewicz, 471 U.S. 462, 477 

(1985). In evaluating the issue, we consider the following factors: (1) the burden 

on the defendant; (2) the interests of the forum state in adjudicating the dispute;

(3) the plaintiff’s interest in obtaining convenient and effective relief; (4) the 

interstate judicial system’s interest in obtaining the most efficient resolution of 

controversies; and (5) the shared interest of the several states in furthering 

fundamental substantive social policies. Guardian Royal Exch., 815 S.W.2d. at 228; 

Magnolia Gas Co. v. Knight Equip. Mfg., 994 S.W.2d 684, 693 (Tex. App.—San 

3 Guardian Royal Exch. Assurance, Ltd. v. English China Clays, P.L.C., 815 S.W.2d 223,

231 (Tex. 1991). 
13

Antonio 1998, no pet.), abrogated in part on other grounds, BMC Software, 83 

S.W.3d at 794 & n.1. When, as here, the defendant is a resident of another nation, 

we also must consider (a) the unique burdens placed on the defendant who must 

defend itself in a foreign legal system, (b) the procedural and substantive policies of 

other nations whose interests are affected by the assertion of jurisdiction by a state 

court, and (c) the federal government’s interest in its foreign-relations policies. 

Guardian Royal Exch., 815 S.W.2d. at 229.

Castelló was the only party to submit evidence on this issue, and viewing the 

evidence together with the record as a whole we think the burden on him to litigate 

this matter in Texas is likely significant. He is a resident of Switzerland, as is 

Hellmund; he has never lived or resided in Houston and only visited Houston “a 

handful of times.” He owns no property and maintains no bank accounts in Texas. 

Texas’s interest in adjudicating this dispute between two nonresident spouses 

is minimal at best. Cf. id. at 232-33 (explaining that Texas’s interest in resolving 

dispute between English insurer and its English insured is minimal, despite English 

insurer’s minimum contacts with Texas). The lawsuit involves whether Castelló

promised to fully fund the purchase and renovation of a single marital asset; 

Hellmund did not allege that these purported promises were made in Texas or to a 

Texas resident. Any promises that Castelló made were to Hellmund, who, like 

Castelló, is a Swiss resident. Though Hellmund ostensibly asserts claims on 

Allegra’s behalf, she notably requested the trial court to treat those claims as a direct 

action on her behalf and award damages directly to her. Currently, Hellmund and 

Castelló are parties to a divorce proceeding in Switzerland that will adjudicate the 

property’s disposition. Texas has no interest in adjudicating divorces between 

spouses who do not reside in this state. See Alwazzan v. Alwazzan, 596 S.W.3d 789, 

808-09 (Tex. App.—Houston [1st Dist.] 2018, no pet.) (citing Tex. Fam. Code 
14

§ 6.301). The “public policy behind these requirements is to prevent forum shopping 

by divorce litigants.” Id. Moreover, for this reason, litigating a dispute in Texas 

over one community asset in a marital estate when the divorce action is pending in 

another country does not provide particularly convenient and effective relief. 

Finally, balancing the relevant international interests—(a) the unique burdens 

placed on the defendant who must defend itself in a foreign legal system; (b) the 

procedural and substantive policies of other nations whose interests are affected by 

the assertion of jurisdiction by a state court; and (c) the federal government’s interest 

in its foreign-relations policies—does not favor a Texas forum for this action. 

Given our disposition, we need not address whether Hellmund’s claims are 

substantially connected to Castelló’s membership in a Texas LLC. See Tex. R. App. 

P. 47.1.

For these reasons, we overrule Hellmund’s first issue. 

Conclusion

Having overruled both of Hellmund’s appellate issues, we affirm the trial 

court’s order granting Castelló’s special appearance.
