OPINION
Relator Charlena Renee Smith filed a petition for writ of mandamus seeking to compel the trial court to vacate a 2002 order naming Sheila Renee Haley joint managing conservator of Smith’s children, and to vacate 2008 temporary orders giving Haley access to and supervision of Smith’s children. We conditionally grant mandamus relief.
Smith gave birth to twins conceived by artificial insemination from an anonymous donor. On September 16, 2002, when the twins were four months old, Smith and Haley filed a joint SAPCR petition. 1 The trial court signed an “Agreed Order in Suit Affecting the Parent-Child Relationship” in October 2002, when the twins were five months old. The order appointed Smith and Haley joint managing conservators, gave them “equal possession of the children at all times[,]” and provided “that no stated рrovisions for possession and access are necessary in light of the fact that the parties cohabitate in the same primary residence.”
Haley and Smith separated on February 12, 2008. Smith filed a motion to vacate the agreed order оn February 13, 2008, and Haley filed a petition to modify the order. The trial court entered an “interim order” and later temporary orders. After the trial court denied Smith’s motion to vacate, she filed this petition for writ of mandamus.
Smith argues the 2002 agreed order naming Hаley as joint managing conservator is void because Haley lacked standing.
See In re SSJ-J,
In the context of suits involving the parеnt-child relationship, the Texas legislature has provided a comprehensive statutory framework for standing.

Tex. Fam.Code Ann. §§ 102.003, 102.0035, 102.004, 102.0045, 102.005, 102.006 (Vernon Supp.2007);
In re H.G.,
No. 04-07-00656-CV, — S.W.3d -, -,
Section 102.003 of the Family Code sets out who generally has standing to file a *466 suit affecting the parent-child relationship. See Tex. Fam.Code Ann. § 102.003. At the February 2008 hearing on the temporary orders, Haley acknowledged she did not have standing at the time of the 2002 order under subdivisions contained in section 102.003 at the time the original petition was filed. 2 Specifically, Haley was not “a person, other than a foster parent, who has had actual care, control, and possessiоn of the child for at least six months ending not more than 90 days preceding the date of the filing of the petition[.]” § 102.003(a)(9). When Haley and Smith filed the petition, the twins were four months old.
Haley’s position appears to be that she is not required to establish standing for hersеlf because Smith’s standing as the twins’ mother was enough to confer jurisdiction upon the trial court. Haley points out that she and Smith had a written agreement concerning conservatorship that was incorporated into the agreed order.
Generally, Tеxas courts resolve controversies in an adversarial context between parties who contest determinative facts or applicable law.

Generally, a party cannot confer jurisdiction either by consent or agreement.
See generally Welder v. Fritz,
Haley contends that equitable es-toppel bars Smith from complaining about the trial court’s exercise of jurisdiction. Estoppel does not operate to prevent the setting aside of a void order.

Haley relies on
Goodson v. Castellanos,
Texas law requires that the person bringing a SAPCR suit meet one of the statutory requirements in the general standing provision in section 102.003 or qualify under other standing provisions in the Family Code.
See
Tex. Fam.Cоde Ann. §§ 102.003, 102.0035(a), 102.004, 102.0045, 102.005 (Vernon Supp.2007). Standing must be established as to each party bringing or joining in the suit.
See generally In re Derzapf,
The trial court entered temporary orders after Haley filed a motion to modify the 2002 order. A trial court cannot modify a void order, however.
See In re Bokeloh,
The tempоrary orders are not supportable even if Haley’s motion to modify the 2002 order is construed as an original SAPCR petition. Chapters 153 and 156 of the Family Code set out distinct statutory schemes for original conservator-ship determinations and modification proceedings. In an original proceeding, there is a “rebuttable presumption that the appointment of the parents of a child as joint managing conservators is in the best inter
*468
est of the child.”
See
Tex. Fam.Code Ann. § 153.131(b) (Vernon 2002). The trial court shall appoint a parent as sole managing conservator, unless the court finds that appointment of the parent would not be in the best interest of the child because the appointment would significantly impair the child’s physical health or emotional development. Tex. Fam.Code Ann. § 153.131(a);
Lewelling v. Lewelling,
The parental presumption stаtute, which applies to an original petition seeking conservatorship, was amended in 2005 and reflects the influence of
Troxel,
Haley had the burden to overcome the parental presumption of section 153.131. Haley did not plead that Smith was an unfit parent or that leaving the children with Smith would significantly impair the child’s physical health or emotional development. She pled materially and substantially changed circumstances as grounds for the order. Haley attached an affidavit stating that she was concerned for the well-being of the children, that an acquaintance of Smith’s used drugs, and that Smith “and certain members of her family have a history of violence.” In issuing the temporary orders, the trial court made no finding that Smith was аn unfit parent or that she would significantly impair the children’s physical health or emotional development. To the contrary, the 2008 order provides for Smith and Haley to rotate
*469
possession and access to the children. Without a determination that Smith is an unfit parent or is endangering the children, the trial court abused its discretion in substituting its judgment for the parent’s judgment.
In re Mata,
We conditionally grant Smith’s petition for writ of mandamus and direct the trial court to vacate its orders of October 23, 2002, and March 11, 2008. The writ will issue only if the trial court fails to take appropriate action in accordance with this opinion.
PETITION FOR WRIT OF MANDAMUS CONDITIONALLY GRANTED.
Notes
. Suit Affecting Parent-Child Relationship. A few years later, Haley gave birth to a son conceived by donation from the same anonymous donor. No SAPCR petition was filed regarding this child.
. Section 102.003(a)(14) was not added to the statute until 2003.
. A prior version of the statute used the term "agreement” rather than "agreed parenting plan.” See Act of April 6, 1995, 74th Leg., R.S., ch. 20, § 1, sec. 153.007, 1995 Tex. Gen. Laws 113, 147, (amended 1995, 2005) (current version at Tex. Fam.Code Ann. § 153.007 (Vernon Supp.2007)).
. An exception to the general rule — that a party cannot confer standing on another — is found in section 102.0035(a) of the Family Code, which provides that a "pregnant woman or a parent of a child may execute a statement to confer standing to a prospective adoptive parent as provided by this section to assert standing under Section 102.003(a)(14).” Tex. Fam.Code Ann. § 102.0035(a) (Vernon Supр.2007). The Legislature did not add section 102.0035 or 102.003(a)(14) to the Family Code until 2003. In any event, this case does not involve adoption. The exception does not apply to the October 2002 order.
. After the temporary orders were signed, Haley filed a request for modification of the temporary orders in which she alleged that "[rjespondent has a history or pattern of committing family violence, and endangering and/or neglecting the children!)]” Haley asks that she be appointed sole managing conservator of Smith’s children. Haley also asks that the request be treated as an original suit affecting the parent-child relationship in the event Smith's mandamus action is successful. We do not address this request as it is not the subject of this mandamus proceeding and has not been ruled on by the trial court.
