Appellee Ernst DeGroot divorced appellant Mary Connole 1 in August 1999 in the District of Columbia. In December 2005, after the parties and their children moved away from the District, Ms. Connole asked the Superior Court to modify the divorce decree to include an order of child support. The trial court denied the motion, concluding that it lacked subject matter jurisdiction because neither the parents nor their children reside in the District.
We hold that the court had continuing subject matter jurisdiction to enter an order for child support. The doctrine of continuing jurisdiction has a long history in the District, and it has been codified.

I. Factual and Procedural Background 2
Mary Connole married Ernst DeGroot in November 1984 in the District of Columbia. The couple had two children, both of whom were born here. After living outside of the District for a few years, the family moved back to this jurisdiction, but the parents separated in 1997.
Mr. DeGroot divorced Ms. Connole in August 1999. The divorce decree awarded Ms. Connole “permanent custody” of the couple’s minor children, and the Superior Court granted Mr. DeGroot “reasonable rights of visitation.” Neither party asked the court to order child support. Rather, the decree provided that “[t]his issue shall remain open [i]f either party elects to seek such relief in the future.” Mr. DeGroot’s attorney sent a letter to Ms. Connole (who was then Mrs. DeGroot) in April 1999, confirming that the couple had “decided between [themjselves about the arrangements for support.”
After the separation, Ms. Connole moved with the children to Maryland; Mr. DeGroot later moved to the Commonwealth of Virginia. Neither Ms. Connole, nor Mr. DeGroot, nor either of the children presently lives in the District.
Mr. DeGroot regularly provided child support to Ms. Connole starting in 1998. Although the amounts varied in the early years after the separation, from February 2000 until September 2004, Mr. DeGroot paid six hundred dollars to Ms. Connole every month. In September 2004, shortly before the older child turned nineteen, Mr. DeGroot unilaterally reduced his child support payments to three hundred dollars per month.
In December 2005, Ms. Connole filed in the Superior Court a Motion to Modify Judgment of Absolute Divorce by Clarifying Clerical Error and Awarding Child Support. Mr. DeGroot opposed the modification, and the Superior Court held a status hearing on February 15, 2006. When it discovered that the parties and the children no longer resided in the District, the trial court raised sua sponte the question of its subject matter jurisdiction to adjudicate the issue of child support.
After accepting briefs on the jurisdictional issue, the trial court denied the motion to modify judgment, ruling that it lacked subject matter jurisdiction. (Mr. DeGroot did not challenge the court’s jurisdiction over his person.) Concluding that UIFSA governed its jurisdiction in the matter, the court held that, in order for it “to have jurisdiction to enter a child support order, one of the relevant parties, i.e., the obligee, the obligor, or the children, must reside in the District of Columbia.” Because none of these persons resided in the District, the court denied Ms. Connole’s motion. This appeal followed.
II. Discussion
“The issue of subject matter jurisdiction is a question of law. Therefore, our standard of review is
de novo.” American University in Dubai v. District of Columbia Education Licensure Comm’n,
A. The Doctrine of Continuing Jurisdiction
The District of Columbia long ago accepted “the general doctrine of the courts of the United States ... that jurisdiction
Mr. DeGroot argues that because the original divorce decree contained no express provision for child support the Superior Court cannot now add one. This is not correct. Continuing jurisdiction includes the power to issue a child support order even though the initial divorce decree is silent on the matter.
See Alves v. Alves,
Clark
dealt with a plaintiff who returned to Superior Court, seeking to reduce ar-rearages to judgment several years after the court had entered a final judgment for absolute divorce.
No case of this court suggests that subject matter jurisdiction to issue a support order expires if all the parties have left the jurisdiction. Addressing the issue of continuing jurisdiction to
enforce
a support order, we have rejected the “view that a court with initial jurisdiction over a question of child support should, without more, lose authority to enforce the decree if both parents move to other jurisdictions.”
Desai v. Fore,
In
Elkins,
the mother sought to increase an allowance for maintenance of their child after the father had moved to New Jersey. Although the court granted an increase, the father failed to comply, and he later challenged the jurisdiction of the court. Discussing both personal and subject matter jurisdiction, the court of appeals concluded that “the defendant was subject to the jurisdiction of the court....”
Mr. DeGroot acknowledges that he “has not challenged the personal jurisdiction of the court regarding modifying the divorce decree.” Instead, he asserts that the trial court lacks subject matter jurisdiction to modify that judgment by adding an order for child support. He suggests that
El-kins
addressed only an issue of personal jurisdiction. As we have indicated, however, the court discussed principles of continuing subject matter jurisdiction, not simply personal jurisdiction.
Elkins,
B. Statutory Grants of Subject Matter Jurisdiction
The Superior Court is “a court of general jurisdiction,”
Andrade v. Jackson,
The legislature has limited the jurisdiction of the Superior Court to grant divorces and to determine child custody. For example, “[n]o action for divorce or legal separation shall be maintainable unless one of the parties to the marriage has been a bona fide resident of the District of Columbia for at least six months next preceding the commencement of the action.” D.C.Code § 16-902 (2001). Moreover, “a court of the District has jurisdiction to make an initial child-custody determination only” under circumstances described in D.C.Code § 16-4602.01(a) (2007 Supp.).
3
Indeed, the Council of the District of Columbia has codified the doctrine of continuing jurisdiction with respect to entering or modifying child support orders. D.C.Code § 16-914.01 (2007 Supp.) states that “[a]fter the issuance of a judgment, decree, or order granting custody, child support, or alimony, the Court retains jurisdiction for the entry of future orders modifying or terminating the initial judgment, decree, or order to the extent the retention of jurisdiction does not contravene other statutory provisions.” Here, of course, the divorce decree granted Ms. Connole custody of the children.
This court has not yet addressed the reach of § 16-914.01, which was enacted by D.C. Law 14-207 (effective October 19, 2002). However, we have interpreted an earlier version of the statute to grant continuing jurisdiction to make orders for support where the original divorce decree was silent on that topic.
Clark,
C. The Impact of UIFSA
We turn now to assess whether — in the words of D.C.Code § 16-914.01 — “retention of jurisdiction” under these circumstances would “contravene other statutory provisions” — in this case UIFSA. “Contravene” is a strong word, defined as “[t]o violate or infringe; to defy” or “to be contrary to.” BlacK’s Law Dictionaey 352
Codified at D.C.Code §§ 46-301.01 to 46-309.01 (2001),

UIFSA attempts to clarify the methods of “establishment, enforcement, or modification of support orders across state lines.”
LeTellier v. LeTellier,
1. Is This a “One-State Proceeding”?
It is crucial to recognize that this case does not involve competing orders for
Although the commentary just quoted suggests that — with two exceptions 7 — none of the provisions of UIFSA apply to a one-state proceeding, the text of UIFSA § 202 expressly excludes only chapters III through VII. See note 7, swpra. This ambiguity is significant because UIFSA § 205, on which appellant principally relies is found in chapter II. Thus, whatever the contours of a one-state proceeding may be, we apparently cannot avoid confronting UIFSA § 205. Furthermore, in Case and LeTellier, the petitioner was a resident of the forum state. We therefore will assume, without deciding, that UIFSA § 205 and the other provisions of UIFSA apply to a case like this which involves residents of two or more states. Even so, appellant has not identified any provision of UIFSA that precludes the Superior Court from issuing a support order in the circumstances presented here.
2. The Rest of UIFSA
Section 401 of UIFSA, codified at D.C.Code § 46-304.01 (2001) (“Petition to
(a) If a support order entitled to recognition under this chapter has not been issued, a responding tribunal of the District may issue a support order if:
(1) The individual seeking the order resides in another state; or
(2) The support enforcement agency seeking the order is located in another state....
Id. The related commentary explains:
This section authorizes a tribunal of the responding state to issue temporary and permanent support orders binding on an obligor over whom the tribunal has personal jurisdiction. UIFSA does not permit such orders to be issued when another support order exists, thereby prohibiting a second tribunal from establishing another support order and the accompanying continuing, exclusive jurisdiction over the matter. See Section 205 (Continuing, Exclusive Jurisdiction) and Section 206 (Enforcement and Modification of Support Order by Tribunal Having Continuing Jurisdiction).[ 8 ]
UNIF. INTERSTATE FAMILY SUPPORT ÁCT § 401 cmt. (1996), 9 U.L.A. 398 (2005). Because Ms. Connole resides in another state, and because no support order has yet been issued, it would not “contravene” UIFSA § 401 if the Superior Court issued an order in this case.
Additional limits on the exercise of subject matter jurisdiction are found in section 204 of UIFSA, codified at D.C.Code § 46-302.04 (2001), and entitled “Simultaneous proceedings in another state.”
9
Section 204 restricts the authority of the Superior Court “to establish a support order,” but only in circumstances not present here.
See, e.g.,
D.C.Code § 46-302.04(a) (describing limited circumstances in which “[a] tribunal of the District
may
exercise jurisdiction to establish a support order if
Nevertheless, Mr. DeGroot insists that the Superior Court lacks subject matter jurisdiction to issue the support order sought by his ex-wife. He points to D.C.Code § 46-302.05 (2001)
11
and especially the corresponding comment in the Uniform Act, which explains that “if all the relevant persons — the obligor, the individual obligee, and the child — have permanently left the issuing state, the issuing state no longer has an appropriate nexus with the parties or child to justify exercise of jurisdiction
to modify.”
Unif. Interstate Family Support Act § 205 cmt. (1996), 9 U.L.A. 340 (2005) (emphasis added).
12
As its language makes obvious, the comment on which Mr. DeGroot relies discusses jurisdiction
to modify
a child support order. This key restriction implements the “one-order system” contemplated by UIFSA.
See In re Marriage of Hillstrom,
As many cases illustrate, subject matter jurisdiction is not a monolithic concept under UIFSA.
See Jurado v. Brashear,
The parties have not cited, and we have not found, a case precisely like this one, but we apply the principles discussed above, refining our inquiry to ask: subject matter jurisdiction to do what? As we have seen, Section 205 and its commentary do not restrict the Superior Court’s jurisdiction to issue or establish a support order in the circumstances presented here, and we have found no other provision of UIFSA that does so. Mr. DeGroot thus
D. Additional Arguments
DeGroot makes two additional points. First, he asks us to uphold the judgment on alternative grounds, arguing that “[dismissal for forum non conveniens reasons would have been appropriate in this case.” A motion to dismiss because the chosen forum is inconvenient calls for an exercise of the “broad discretion” of the trial court.
See Rolinski v. Lewis,
III. Conclusion
We conclude that the Superior Court has subject matter jurisdiction to enter a child support order under the circumstances presented. 16 Accordingly, we reverse the judgment of the Superior Court and remand for further proceedings consistent with this opinion.
So ordered.
Notes
. On January 6, 2006, the Superior Court corrected a typographical error in the divorce decree to restore Mary Connole DeGroot to her former name — Mary Margaret Connole.
. Many of these facts are taken from the affidavit of Ms. Connole. At this stage of the proceedings, we view the facts in the light most favorable to the non-moving party.
. D.C.Code § 16-4602.01(a) provides:
§ 16-4602.01. Initial child-custody jurisdiction.
(a) Except as otherwise provided in section 16-4602.04, a court of the District has jurisdiction to make an initial child-custody determination only if:
(1) The District is the home state of the child on the date of the commencement of the proceeding, or was the home state of the child within 6 months before the commencement of the proceeding and the child is absent from the District, but a parent or person acting as a parent continues to live in the District;
(2) A court of another state does not have jurisdiction under paragraph (1) of this subsection, or a court of the home state of the child has declined to exercise jurisdiction on the ground that the District is the more appropriate forum under sections 16-4602.07 or 16-4602.08, and:
(A) The child and the child’s parents, or the child and at least one parent or a person acting as a parent, have a significant connection with the District other than mere physical presence; and
(B) Substantial evidence is available in the District concerning the child’s care, protection, training, and personal relationships;
(3) All courts having jurisdiction under paragraph (1) or (2) of this subsection have declined to exercise jurisdiction on the ground that a court of the District is the more appropriate forum to determine the custody of the child under sections 16-4602.07 or 16-4602.08; or
(4) No court of any other state would have jurisdiction under the criteria specified in paragraph (1), (2), or (3) of this subsection.
. The 2002 revision replaced language which stated that ‘‘[ajfter the issuance of a decree of divorce granting alimony and providing for the care and custody of children, the case shall still be considered open for any future orders.” D.C.Code § 16-914(a)(l) (2001). The Committee Report to the Council explains that the new provision "builds on” earlier language and "allows the court to maintain jurisdiction over the custody, child support or alimony decree.” Council of the District of Columbia Committee on the Judiciary, Report on Bill 14-635, the “Domestic Relations Laws Clarification Act of 2002,” at 3 (May 29, 2002).
. The 1996 version of UIFSA, in effect when the Superior Court ruled, was adopted by the Council in 1998.
See
D.C.Code § 46-301.01 (2001) (Historical and Statutory Notes); Unif. Interstate Family Support Act (1996), 9 U.L.A. 293 (2005). D.C. Law 16-137 subsequently amended those provisions to conform to the 2001 version of UIFSA, but those revisions did not take effect until April 1, 2007, D.C.Code § 46-301.01 (Supp.2007) (Historical and Statutory Notes), after the Superior Court ruled on the issues now before us. Notwithstanding the judiciary’s presumption against retroactive legislation,
see Landgraf v. USI Film Products,
. The Council did not enact the commentary that accompanies the pattern legislation, but it has cautioned that UIFSA "shall be applied and construed to effectuate its general purpose to make uniform the law with respect to the subject of this chapter among states enacting it.” D.C.Code § 46-309.01 (2001). "Therefore, we [may] properly look to the official comments contained in the model act for some guidance in an effort to ascertain the intent of the legislation.”
Groseth v. Groseth,
. The two exceptions are set forth in UIFSA § 202, codified at D.C.Code § 46-302.02 (2001), which provides:
Procedure when exercising jurisdiction over nonresident.
The Family Division, if it is exercising personal jurisdiction over a nonresident under § 46-302.01, may apply § 46-303.15 (special rules of evidence and procedure) to receive evidence from another state, and § 46-303.17 (assistance with discovery) to obtain discovery through a tribunal of another state. In all other respects, subchap-ters III through VII of this chapter do not apply and the tribunal shall apply the procedural and substantive law of the District, including the rules on choice of law other than those established by this chapter.
. D.C.Code § 46-301.01(20) (2001), defines “responding tribunal” as “the authorized tribunal in a responding state.” D.C.Code § 46-301.01(19) (2001), in turn defines "responding state” as “a state in which a proceeding is filed or to which a proceeding is forwarded for filing from an initiating state under this chapter....” UIFSA treats the District of Columbia as a "state,” D.C.Code § 46-301.01(22) (2001), and the Family Division of the Superior Court is a "responding tribunal” in this case because it is the authorized tribunal of "a state in which a proceeding is filed....” D.C.Code §§ 46-301.01, 301.2 (2001).
. The statute reads as follows:
§ 46-302.04. Simultaneous proceedings in another state.
(a) A tribunal of the District may exercise jurisdiction to establish a support order if the petition or comparable pleading is filed after a petition or comparable pleading is filed in another state, but only if:
(1)The petition or comparable pleading in the District is filed before the expiration of the time allowed in the other state for filing a responsive pleading challenging the exercise of jurisdiction by the other state;
(2) The contesting party timely challenges the exercise of jurisdiction in the other state; and
(3) If relevant, the District is the home state of the child.
(b) A tribunal of the District may not exercise jurisdiction to establish a support order if the petition or comparable pleading is filed before a petition or comparable pleading is filed in another state if:
(1) The petition or comparable pleading in the other state is filed before the expiration of the time allowed in the District for filing a responsive pleading challenging the exercise of jurisdiction by the District;
(2) The contesting party timely challenges the exercise of jurisdiction in the District; and
(3) If relevant, the other state is the home state of the child.
D.C.Code § 46-302.04 (2001).
. D.C.Code § 46-302.04(b)(1) seems to contemplate that the competing petition in another state would be filed by a parent who contests the jurisdiction of the District of Columbia. That did not happen here. In any event, Ms. Connole’s "protective” suit did not restrict the authority of the Superior Court to establish a support order because she filed it after Mr. DeGroot had answered her motion in this jurisdiction. See id.
. Section 46-302.05, entitled “Continuing, exclusive jurisdiction,” provides in part:
(a) A tribunal of the District issuing a support order consistent with the law of the District has continuing, exclusive jurisdiction over a child support order:
(1) As long as the District remains the residence of the obligor, the individual obligee, or the child for whose benefit the support order is issued; or
(2) Until all of the parties who are individuals have filed written consent with the tribunal of the District for a tribunal of another state to modify the order and assume continuing, exclusive jurisdiction.
. The comment further explains that “by clear implication the subsection also defines how jurisdiction to modify [a child support order] may be lost.” Unif. Interstate Family Support Act § 205 cmt. (1996), 9 U.L.A. 340 (2005). Section II.D.2 of the prefatory note states that "[ejxcept for narrowly defined fact circumstances, under UIFSA the only tribunal that can modify a support order is the one having continuing, exclusive jurisdiction over the order.” Id., 9 U.L.A. 288.
. The scope of UIFSA § 205 is made even more clear by its current title, "Continuing, exclusive jurisdiction to modify child-support order.” D.C.Code § 46-302.05 (2007 Supp.) (effective April 1, 2007).
. As discussed above, Ms. Connole has asked the Superior Court to modify the divorce decree. That, of course, is a different matter, not governed by UIFSA.
. Citing the commentary to UIFSA § 201;
M.F. v. W.P.,
. Before concluding, we underscore the limits of our holding. The trial court stated that it "[did] not consider [Ms. Connole’s] motion to be a petition, [subject to transfer] as described in D.C.Code § 46-303.10.” We do not address that issue here. Likewise, it is not necessary to consider Ms. Connole’s alternative argument that the Superior Court had jurisdiction to enforce an oral promise to furnish child support (allegedly made in the District of Columbia). Furthermore, we have not conducted any choice of law analysis, either under
Mims v. Mims,
