OPINION
Appellant, Lisa Rae Ragsdale McGuire (“Wife”), appeals from an order modifying child support in favor of Charles Francis McGuire (“Husband”). We affirm.
Facts
In 1992, Husband and Wife signed an agreement incident to divorce (“Agreement”), which required Husband to pay $800 per month in child support and conditionally granted him the tax exemptions for their three dependent children. About seven months later, in 1993, Husband and Wife were divorced. The final divorce degree incorporated the Agreement’s provisions for child support and tax exemptions.
In 1996, Husband stopped paying child ■support. In 1997, the trial court found him in contempt and ordered him to pay the arrearages. Less than three weeks later, Husband moved to modify the suit affecting the parent-child relationship. He sought to reduce his payment obligations, arguing that his circumstances had “materially and substantially” changed. See Tex. Fam.Code Ann. § 156.401 (Vernon 1996). The trial court reduced Husband’s monthly child support payments from $800 to $288 and apportioned the tax exemptions between Husband and Wife. Wife appeals the trial court’s order in four points of error.
Standard of Review
A trial court’s ruling on child support will not be reversed on appeal unless there is a clear abuse of discretion.
Worford v. Stamper,
Agreement Incident to Divorce
In her first point of error, Wife contends that the trial court erred by not enforcing the Agreement for child support and tax exemptions. 1
*385
Wife’s first point of error does not direct this Court’s attention to any specific error on which she bases her complaint.
See
Tex.R.App. P. 38.1(e). A complaint on appeal must address specific errors and not merely attack the trial court’s order in general terms.
Hollifield v. Hollifield,
Turning to the merits, Husband and Wife signed the Agreement, which was later incorporated by reference into their final divorce degree. Both the Agreement and decree required Husband to pay $800 per month in child support. There is no dispute as to whether the trial court had the authority to reduce the support payments in the decree. Instead, Wife argues that the trial court should have enforced the prior Agreement at the modification hearing. In other words, she contends that the $800 obligation in the Agreement should continue to exist as a separate source of liability.
This Court has previously held that an agreement incident to divorce does not prohibit a modification of support payments.
See Leonard v. Lane,
In contrast, the case of
Ruhe v. Rowland,
Similarly,
Alford v. Alford,
Alford is distinguishable because, after searching the record in this case, we found no' such language in either the Agreement or the decree. Nor did Wife provide any record citations to prove that the Agreement and decree were intended to be separate. See Tex.R.App. P. 38.1(h). To the contrary, the Agreement stated that it “shall become incorporated by reference” *386 into the decree. Both the Agreement and decree ordered the same support amounts and payment schedules. Moreover, Wife concedes that the Agreement “was attached to” and “was ordered and incorporated into” the decree.
When an agreement is incorporated into a divorce decree, the decree is a consent judgment.
Rivera v. Office of Attorney Gen.,
Likewise, the Agreement in this case was not merely a contract. It became a court judgment once it was incorporated into the decree. Thus, the trial court had the authority to modify Husband’s payment obligations.
See Leonard,
Moreover, a child support agreement must specifically provide for contract enforcement to be enforceable as a contract. Tex. Fam.Code AnN. § 154.124(c). Terms of the agreement in the divorce order may be enforced “by all remedies available for enforcement of a judgment, including contempt, but are not enforceable as contract terms unless provided by the agreement.” Id. Because neither the divorce decree nor the Agreement provided that the terms were enforceable as contract terms, contractual remedies are not available. We hold that the trial court had the authority to modify the divorce decree and did not abuse its discretion in failing to enforce the Agreement incident to divorce.
Additionally, in her first point of error, Wife contends that the trial court should have excluded Husband’s 1992 tax return because it predated the 1993 divorce decree.
A court may modify a child support order if the circumstances have materially and substantially changed “since the date of the order’s rendition.” Tex. Fam.Code Ann. § 156.401 (Vernon 1996). To support her argument, Wife relies on
Ritter v. Wiggins,
This case is distinguishable from the seven-year time differential in the
Ritter
case.
Id.; cf. Bradshaw v. Billups,
Moreover, Wife did not object at the hearing when Husband’s 1992 tax return was introduced and admitted in evidence. Without a trial objection, Wife waived the right to raise this complaint on appeal. Tex.R.App. P. 33.1(a).
We overrule the first point of error.
Modification of Child Support
In her fourth point of error, Wife contends that the evidence is legally and factually insufficient to establish a ma *387 terial and substantial change in Husband’s circumstances. 2
As set forth above, a trial court may modify a child support order if the circumstances have “materially and substantially changed.” Tex. Fam.Code Ann. § 156.401 (Vernon 1996). The primary consideration is the best interest of the child.
Id.
at § 156.402(b). The court retains broad discretion in modifying a prior support order.
Hollifield,
Husband sought to reduce his child support payments, arguing that his net income had decreased. His evidence included his own testimony, his accountant’s testimony, and his financial information for 1992, 1995, 1996, and 1997. Husband showed that in 1992, his salary as a full-time employee for a remodeling company was about $2,255 per month. While still married in 1993, he left the company and started his own remodeling business. In 1997, his projected earnings were about $1,218 per month.
Like Husband, the father in
Starch v. Nelson,
The trial court in this case was free to believe or disbelieve Husband’s evidence.
See Tucker v. Tucker,
Moreover, the trial court’s prospective child support order of $288.80 per month did not vary from the Family Code’s guidelines. An order that conforms to the guidelines, such as the order in this case, is presumed to be reasonable and in the best interest of the child. Tex. Fam.Code Ann. § 154.122(a) (Vernon 1996). We hold that the record before us does not disclose a clear abuse of discretion.
We overrule the fourth point of error.
Needs of the Children
In her second point of error, Wife contends that the trial court erred when it did not set the child support based on the needs of the children.
In addition to the Family Code’s guidelines, a trial court “may consider other relevant evidence” in ordering child support. Tex. Fam.Code Ann. § 156.402(b) (Vernon 1996). For example, some of the additional factors are:
(1) the age and needs of the child;
(2) the ability of the parents to contribute to the support of the child;
(3) any financial resources available for the support of the child; and ...
(17) any other reason consistent with the best interest of the child, taking into consideration the circumstances of the parents.
Tex. Fam.Code Ann. § 154.123(b) (Vernon 1996). The trial court, therefore, retains
*388
broad discretion.
Hoffman v. Hoffman,
Here, the support order is presumed to be reasonable and in the best interest of the child because it did not vary from the Family Code’s guidelines. Tex. FaM.Code ÁNN. § 154.122(a). Nevertheless, Wife argues that the trial court should have considered the “needs of the children.” This factor, however, is only one of a nonex-haustive list of seventeen additional factors that a court “may” consider. We hold that the trial court did not err in failing to set child support on the additional factor regarding the needs of the children.
Wife also contends that the evidence is legally and factually insufficient to show that needs of the children had materially changed. Husband was required to prove that the circumstances of either “the child or a person affected by the order” had materially changed. Tex. FaM.Code Ann. § 156.401. Under the statute, Husband was not required to prove both. As set forth above in point of error four, Husband proved that his own circumstances had materially changed. Additional proof regarding the children’s needs was not necessary.
Baucom v. Crews,
We overrule the second point of error.
Intentional Underemployment
In her third point of error, Wife contends that the trial court should have based the child support on Husband’s earning potential, instead of on his actual earnings, because Husband was intentionally underemployed. Tex. Fam.Code Ann. § 154.066 (Vernon 1996).
Husband became self-employed in the remodeling business because it appeared “more lucrative” than teaching. In 1996, he earned about $15,000, and expected to earn a little less than that in 1997. Wife argues that Husband could earn more money as a salaried, full-time employee, either in the remodeling business or as a certified teacher.
Regarding the remodeling business, Husband’s accountant testified that incomes range “anywhere from $12,000 yearly up to $20,000,” but rarely up to $28,000. Husband’s self-employment income fell within that range. Moreover, Husband testified that he doubted if he “could make more money working for another company.” He explained that he was not intentionally underemployed. Instead, he was “forced” to start his own business in 1993 because companies began to use contract labor to save money and “don’t have people like [him] anymore.”
Regarding teaching, evidence was presented that teachers earn between $23,000 and $33,000 per year. However, Husband argued that he did not have enough teaching experience to earn a salary in the higher range. In fact, he had previously earned only $11,200 per year as a certified teacher.
The trial court did not make findings on the issue of intentional underemployment. Husband testified that he thought self-employment would be “more lucrative”; however, he surely did not foresee that his earnings would decrease.
See Starck,
We overrule the third point of error.
We affirm the order of the trial court.
Notes
. Specifically, Wife complains that "the trial court erred and abused its discretion when it failed to enforce the agreement incident to divorce for child support and conditional use of the federal tax exemptions” because there *385 is no evidence or insufficient evidence to support "extinguishing and merging the agreement setting child support into a post-judgment modification of the 1993 consent decree.” To support her argument that the trial court cannot amend the agreement incident to divorce, she asserts various contract rules such as duress, lack of knowledge, mistake, and parol evidence.
. In the child support context, sufficiency challenges are not independent points of error, but are incorporated into an abuse of discretion determination.
