BOWER, Chief Judge.

Garry Mattix appeals and Amy Mattix cross-appeals the district court’s 

modification of the physical-care and child-support provisions of their dissolution 

decree. We reverse the modification of physical care because Garry failed to 

prove the requisite change of circumstances and ability to provide superior 

parenting. We modify the increased child-support obligation in light of the physicalcare ruling, and we reverse the ruling requiring Garry to pay extracurricular activity 

expenses. We find no abuse of discretion in the denial of retroactive child support 

modification. We affirm the court’s order that Garry pay Amy’s trial attorney fees,

and we order Garry to pay $7000 toward Amy’s appellate attorney fees.

I. Background Facts.

Garry and Amy were married in May 2004. They share one child together, 

H.M. In 2009, Garry filed a petition for dissolution. The parties’ settlement 

agreement was adopted by the court, and a stipulated decree was filed on 

February 17, 2010. The decree granted joint legal custody, physical care was 

placed with Amy, and Garry received liberal visitation. If the parties could not 

otherwise agree, Garry’s parenting time was to be on Tuesday and Thursday 

nights and every other weekend from Friday at 5:00 p.m. through Sunday at 5:00 

p.m.1 The decree also set out a vacation and holiday schedule. Garry’s childsupport obligation was set at $500 per month based on an income of $60,000 per 

year as a self-employed trucker and Amy’s income of $51,843 per year.

 

1 Essentially, the custodial schedule provided Amy with eight overnights and Garry 

with six overnights each two-week period. 
3

On January 16, 2020, Garry filed a petition to modify physical care and 

support. Garry claimed a material and substantial change of circumstances had 

occurred because then fourteen-year-old H.M. had been “primarily residing” with 

him. Garry asked the court to grant him physical care, set a visitation schedule, 

award him past and future child support, and assess Amy the costs of the action

(including attorney fees). 

Amy filed an answer seeking dismissal of Garry’s petition, modification of 

child support consistent with the child-support guidelines, and an order that Garry 

pay Amy’s attorney fees. 

After receiving exhibits and hearing the testimony of the parties, other 

witnesses, and the child, the trial court wrote an extensive and thoughtful ruling. 

Significantly, the court made these findings:

This modification action is somewhat unique. There are 

absolutely no facts showing that Amy has done anything to 

jeopardize the child’s best interests. In fact, Garry testified that Amy 

is a great mother. Likewise, Amy has not taken some action that has 

interfered with Garry’s parenting time, such as a change in 

residence. In fact, Amy has lived in the same home for the past 

fifteen years.

The modification request is based solely on the fact that H.M.

has been spending more time at Garry’s home than Amy’s home 

over the past two to three years. This has occurred for multiple 

reasons. First, the parents are exceedingly willing to let the child do 

what he wants. If H.M. wants to spend more time at Garry’s home, 

both parents have been and continue to be willing to let him do that. 

Second, the parents have worked together well to allow the child to

move between their homes notwithstanding the schedule set forth in 

the decree. Third, as the child has got[ten] older, he has enjoyed 

spending more time with his father because they have shared

interests, such as hunting. Finally, Garry’s residence has 

considerably more amenities and more privacy, which make it a more 

attractive location than Amy’s home.

In light of the cooperation between parents on letting H.M.

stay where he wants, it seems surprising that the matter found its 
4

way into court. After all, the mantra when deciding child custody is 

to provide for the best interests of the child. Garry agrees that Amy 

is a good mother and she does not interfere with his parenting time. 

There was no evidence presented to show that a court-ordered 

modification to the dissolution decree would advance the best 

interests of the child.

Later in the court’s ruling, the court also observed:

Based on the legal standards set [forth] above, there seems to be no 

avenue for Garry to meet his heavy burden to show a modification of 

custody. Garry did not show that he can offer superior care than 

Amy. The only real reason offered in favor of modifying custody is 

that H.M. likes spending more time at Garry’s home because he has 

more things to do there. I do not question the truth of this reason. It 

makes sense. H.M. and Garry have common interests. Garry has 

bought a very nice residence, built a barn, and purchased animals

that feed into H.M.’s interests.

Nonetheless, the court did modify physical care, placing the child in the 

parents’ shared care. And the court modified Garry’s child-support obligation to 

$845.88 per month.

2

 The court also ordered Garry to pay his own attorney fees 

as well as Amy’s.

 

2 Garry does not argue the court’s findings as to his income are inaccurate. We 

emphasize these findings of the trial court:

A court-ordered change in custody would impact child 

support, and that is the true purpose for this proceeding. Garry has 

been obstructive [in the manner he makes] child support payments 

since the beginning of his court-ordered obligation. . . .

. . . .

Garry was not upfront about his income. He listed his income 

on his financial affidavit and child support worksheet at $76,091.75 

from GNA Trucking, LLC (GNA), which is a company he owns.

However, his savings and purchases listed in the prior paragraph 

clearly show greater income. GNA’s 2018 tax return showed a net 

business income of $193,791. If the business income is added to 

Garry’s salary, his total income would be $269,791. Garry reported

$20,000 in income per month on his 2020 home loan application, 

which is close to the amount of income realized by Garry and GNA 

in 2018. Garry also owns a roofing company that he described as 

cash flowing but had not shown a profit on a tax return yet. However, 
5

Garry appeals, arguing the court should have placed the child in his physical 

care since the child was primarily residing with him. And if physical care is 

modified, Garry asserts child support should be recalculated because “Garry is 

providing for more of the child’s basic financial needs including shelter, food, water, 

and utilities.” He asserts he should be awarded retroactive child support as well. 

In addition, Garry objects to the court ordering the parties to share the child’s 

extracurricular expenses—with him paying seventy-five percent—because neither 

party asked the court to address the issue. Finally, Garry contends the court 

abused its discretion in ordering him to pay Amy’s attorney fees. 

On cross-appeal, Amy contends the court erred in modifying physical care. 

She asserts the court properly modified child support but it should be based on her 

having physical care and should have been retroactive to May 13, 2020. She 

seeks an award of appellate attorney fees. Garry filed no responsive brief. 

II. Scope and Standard of Review.

“‘Petitions to modify the physical care provisions of a divorce decree lie in 

equity.’ Thus, we review the district court’s decision de novo. Though we make 

our own findings of fact, we give weight to the district court’s findings.” In re 

Marriage of Harris, 877 N.W.2d 434, 440 (Iowa 2016) (internal citations omitted).

We review an award of attorney fees for an abuse of discretion. In re 

Marriage of Kimbro, 826 N.W.2d 696, 698 (Iowa 2013).

 

he did not provide any personal or business tax returns for 2019 or 

2020, so his income may be greater now that his roofing business is 

off the ground. These figures show that Garry vastly understated his

income on his financial documents.

III. Discussion.

Physical care. Familiar principles are at play. A party seeking modification

of a dissolution decree “faces a heavy burden, because once custody of a child 

has been fixed, ‘it should be disturbed only for the most cogent reasons.’” Harris, 

877 N.W.2d at 440 (citation omitted). To justify modification, the movant “must 

prove by a preponderance of the evidence a substantial change in circumstances 

occurred after the decree was entered.” Id. “The changed circumstances affecting 

the welfare of [the] child[] and justifying modification of a decree ‘must not have 

been contemplated by the court when the decree was entered, and they must be 

more or less permanent, not temporary.’” Id. (citation omitted). Moreover, the 

movant “must also prove a superior ability to minister to the needs of the child[].” 

Id.

Garry asserts the child’s change of time spent at his residence rather than 

Amy’s house is a substantial change of circumstances warranting modification of 

the decree and placing H.M. in his physical care.3 He argues:

The undisputed evidence showed that, for at least the two years 

preceding the trial, the child was spending over double the amount 

of time living with Garry than Amy. Specifically, from July 2019 until 

the date of trial in August 2021, the child was in Garry’s physical care 

66% of the time, Amy’s 24% of the time, and with friends, family, or 

other caregivers 10% of the time. There were also significant 

stretches of time where the child was not in Amy’s care at all.

Notably, after the filing of the Petition to Modify, Amy had a [fiftyfour]-day span in March, April, and May of 2020, and another [twentynine]-day span leading up to the trial date where she did not exercise 

any visitation or provide any physical care for the child. 

 

3 We cannot say the decretal court would not have contemplated that H.M. would 

likely spend more time with his father as he got older.
7

Garry’s brief ignores a number of important points. Beginning in March 

2020, COVID-19 created health consequences for vulnerable people—including 

Amy’s parents and H.M.’s younger siblings. Garry refused to take the health risks 

seriously or take precautions—such as masking, physical distancing, and 

vaccinating (when that option became available)—to reduce the risk to Amy’s 

important others, himself, or H.M. H.M. adopted Garry’s cavalier approach and 

continued to socialize with peers despite Amy’s requests for caution. This attitude 

led to H.M. spending several weeks at Garry’s home in 2020.

Also, Garry has provided a number of incentives any teenage child would 

find hard to resist. He purchased a large home in the country where he and H.M. 

participate in many outdoor activities together. The child has his own bedroom 

where he does not have to share space with his younger siblings, as he does at 

Amy’s home.

4 Garry put up a barn and purchased a number of animals the child 

enjoys caring for. He provided the child with a vehicle (the first one was owned by 

the father’s business) and allowed the child to drive to school—but only if the child 

slept at Garry’s home. Garry also allows the child to avoid attending school, 

resulting in notices of truancy.

“The parent awarded physical care maintains the primary residence and 

has the right to determine the myriad of details associated with routine living, 

including such things as what clothes the child[] wear, when they go to bed, with 

 

4 As Amy testified: 

I totally get it that he wants to be there. There’s a lot more freedom. 

There’s a lot more things for him to do over there, frankly, than there 

is here, and I understand that. There’s also not a younger brother 

and sister, you know, up his rear-end all the time.

whom they associate or date, etc.” In re Marriage of Hansen, 733 N.W.2d 683, 

691 (Iowa 2007). Where the fifteen-year-old boy “primarily resides” does not carry 

much weight under the circumstances presented here. As physical custodian, 

Amy has “the right and responsibility to maintain a home for the minor child and 

provide for the routine care of the child.” Iowa Code § 598.1(7) (2020). That right 

and responsibility does not change when the child sleeps elsewhere. 

Amy testified that “wherever [H.M.] lays his head for the night, [she’s] still 

doing the actual majority of the parenting, the school contacts, the sports, the 

appointments, the doctors, you know, every day.” The record supports her 

testimony, and we adopt the trial court’s findings: 

H.M. missed twenty days of school last year while staying primarily 

at Garry’s home. Not only did Garry fail to force H.M. to go to school, 

Garry often instigating the absences by taking H.M. hunting and on 

vacations on school days. Garry condoned H.M. driving beyond his 

restricted driver’s permit. While Garry trumpets that H.M. is learning 

responsibility raising animals, he does not force H.M. to take

responsibility in the other areas referenced above. “Responsible” is 

defined as being “able to answer for one’s conduct and obligations.” 

H.M. is not responsible to his obligation to attend class. He is not 

responsible to his obligation to follow the law as to driving. He has 

shown he is not always responsible to his obligation to treat his 

mother with respect when he disagrees with her. Responsibility is 

learned when a person abides by obligations that they do not want 

to do, as opposed to things that the person enjoys doing.

In contrast, Amy conducts essentially all communications with 

the school and most of H.M.’s activities. She monitors H.M.’s school 

progress. Amy pays for registration and fees for school and sports 

while Garry focuses on nonessential items such as out of state 

baseball tournaments, bats, farm animals, and hunting clothing. 

Amy sets medical appointments. Amy could do a better job holding 

H.M. accountable, but these parents have given H.M. so much

freedom to do what he wants, it is going to be more difficult now that 

he is sixteen. Still, Amy is performing many of the tasks that need to 

be done on a day-to-day basis. Garry showed no interest in taking 

on these tasks. Based on the established legal standards, the 

petition for modification should be denied.

The trial court modified physical care despite finding a change was not in 

the child’s best interests and Garry had not proved a superior ability to minister to 

the needs of the child. This was an error.

This court has previously stated:

[T]here may be a point at which one parent has been the de facto 

physical caretaker for an extended period of time such that the 

decree should be modified to reflect that reality. That is not this case. 

In the typical de facto care claim, the parent granted physical care 

has abandoned the child to the care of the other parent for a long 

period of time. See, e.g., In re Marriage of Spears, 529 N.W.2d 229, 

229 (Iowa Ct. App. 1994) (granting modification where mother left 

the area); In re Marriage of Scott, 457 N.W.2d 29, 32 (Iowa Ct. App.

1990) (granting modification where mother moved to another state 

and left daughter in father’s care for two years); In re Marriage of 

Green, 417 N.W.2d 252, 252–53 (Iowa Ct. App. 1987) (granting

modification where custodial mother moved 150 miles away and left 

children with the father for two years). This case is more analogous 

to In re Marriage of Caldwell, No. 06–1369, 2007 WL 912124, at *2 

(Iowa Ct. App. Mar. 28, 2007). In Caldwell, the father had physical 

care of the children but granted the mother liberal visitation due to 

work schedules. See Caldwell, 2007 WL 912124, at *1. The mother 

argued there had been a de facto transfer of primary physical care.

The court rejected the claim, concluding the father was merely 

granting more visitation to the mother than was required in the 

decree while also providing daily care for the children. See id. at *2. 

The same rationale applies here.

In re Marriage of Brus, No. 14-1722, 2015 WL 4642535, at *3 (Iowa Ct. App. 

Aug. 5, 2015).

The trial court found Garry’s “true purpose for this proceeding” was to

change his child-support obligation. The court noted child-support guidelines 

would allow consideration for extraordinary visitation but limited that credit. The 

court concluded “the [guideline] rules insinuate that physical care should be 

deemed with the parent who has the child the majority of the nights.” The court 
10

thus modified custody based on its interpretation of the support guidelines. We 

cannot agree with the court’s reasoning.

Our case law regarding the modification of physical care is clear. See 

Harris, 877 N.W.2d at 440. A modification is to occur “only for the most cogent 

reasons.”5 Id. Garry’s incentives and Amy’s willingness to allow H.M. to spend 

more time with his father are not the most cogent reasons. Garry did not prove the 

requisites for modification, and we therefore reverse the court’s ruling with respect 

to physical care. Physical care remains with Amy.6 

Child support. Garry’s appeal of the court’s modification of child support is 

premised on his claim the child should be in his physical care. Because we have 

rejected this premise, we do not address his argument for support modification

further. 

Iowa Code section 598.21C(2)(a) provides, “[A] substantial change of 

circumstances exists when the court order for child support varies by ten percent 

or more from the amount which would be due pursuant to the most current child 

 

5

“Cogent” means “appealing forcibly to the mind or reason: convincing.” Cogent,

Merriam-Webster, https://www.merriam-webster.com/dictionary/cogent (last 

visited June 1, 2022).

6 When parents with children separate, the courts are oftentimes required to make 

definitive rules for parents who cannot agree how to divide their time with the 

children. Under the decree, Garry has “liberal rights of visitation.” These parents 

can agree to liberal visitation that is different than the court’s decretal schedule. 

See In re Marriage of Heiar, 954 N.W.2d 464, 472 (Iowa Ct. App. 2020) (‘When 

two good parents are involved, the physical care parent—with the best interests of 

the children at the forefront—knows open, flexible visitation generally benefits the 

children. We affirm the visitation schedule in the decree but emphasize that these 

are minimum guidelines and parents can certainly agree to expand time beyond 

what is ordered.”). However, the court cannot disregard the legal requisites for 

modification.
11

support guidelines.” Amy has asserted a claim for modification of child support 

based on a change of circumstances. The district court “use[d] Amy’s child support 

guidelines worksheet for purposes of projecting income for each parent.” The court 

then filed its own guidelines worksheet based on its finding of shared care. It 

ordered an increase in Garry’s child support and determined the new amount 

would begin on the first of the month following filing of its decision. 

Amy asserts that because modification of care was not proved, Garry’s child 

support under the guidelines should be $1295.39 per month. Garry has not refuted 

this calculation. Because we agree it was error to modify the physical care 

provision of the decree and that there is a substantial change of circumstances to 

support modification of the support obligation, we modify Garry’s child support to 

$1295.39 per month.

Amy asserts the modification should be retroactive to May 13, 2020—three 

months following notice of her counterclaim for modification of child support. Iowa 

Code section 598.21C(5) states that child support “may be retroactively modified 

only from three months after the date the notice of the pending petition for 

modification is served on the opposing party.” (Emphasis added.) “Making a 

support award retroactive is permissible, not mandatory, and the district court has 

discretion in determining whether such retroactive application is warranted.” 

Christy v. Lenz, 878 N.W.2d 461, 469 (Iowa Ct. App. 2016). Given that our review 

is for an abuse of discretion, we cannot say the district court abused its discretion

here. 
12

Extracurricular activity expenses. Garry objects to the court ordering the 

parents to pay a proportionate share of H.M.’s extracurricular activity expenses in 

relation to their incomes. The district court divided the extracurricular expenses

based on its modification to shared care. Amy notes Iowa Court Rule 9.14(3) 

states that a child’s expenses may be ordered pursuant to Iowa Code

section 598.41(5)(a) as an obligation in addition to the joint physical care child

support offset. 

But we have agreed with Amy that the court erred in modifying custody. 

And we have modified Garry’s child support based on Amy having physical care

and crediting Garry with extraordinary visitation. “[E]xpenses for clothes, school 

supplies and recreation activities are considered under the guidelines, and a 

separate support order covering such expenses is improper absent a finding that 

the guidelines amount would be unjust or inappropriate.” In re Marriage of Gordon, 

540 N.W.2d 289, 292 (Iowa Ct. App. 1995); see Heiar, 954 N.W.2d at 473 

(reversing the district court ruling requiring former spouse to pay extracurricular 

activity enrollment fees and required supplies in addition to his child-support 

obligation). We reverse the order to pay extracurricular activity expenses.

We note, though, the guidelines cover the types of financial obligations 

normally incurred by other children of similar ages. See Heiar, 954 N.W.2d at 473. 

Expenses that “would be significantly different than those normally incurred by 

other children of similar ages,” however, “may justify an extraordinary expense 

clause, or a deviation from the guidelines.” See id. 
13

Trial attorney fees. Garry contends the district court abused its discretion in 

ordering him to pay all of Amy’s attorney fees. Iowa Code section 598.36 provides, 

“In a proceeding for the modification of an order or decree under this chapter the 

court may award attorney fees to the prevailing party in an amount deemed 

reasonable by the court.” The district court determined, 

Garry shall also be responsible for all of Amy’s attorney fees. 

This action was totally unnecessary. These parties could have 

continued to go on as they have. Following trial, the result is that 

they will continue to go on as they have, but with a new child support 

order in place. Amy has a good job, but she has three children and 

little disposable income to pay an attorney. This action was entirely

driven by Garry. She should not be responsible for those costs.

On appeal, Garry contends that because the court modified child custody, 

he was the prevailing party and thus should not be required to pay Amy’s attorney 

fees. But we have concluded the modification of child custody was in error, we 

affirmed and further modified on Amy’s request for modification of child support. 

Garry is not entitled to attorney fees under section 598.36; Amy is. We find no 

abuse of discretion. 

Appellate attorney fees. “Appellate attorney fees are awarded upon our 

discretion and are not a matter of right.” Id. “[W]e consider ‘the needs of the party 

seeking the award, the ability of the other party to pay, and the relative merits of 

the appeal.’” In re Marriage of McDermott, 827 N.W.2d 671, 687 (Iowa 2013) 

(citation omitted). Amy has requested $7500 for her appellate attorney fees. She 

was obligated to dispute the erroneous change of custody and defend the 

modification of child support. Garry was successful only on the issue of 
14

extracurricular expenses. We order Garry to pay $7000 toward Amy’s appellate 

attorney fees. Costs are assessed to Garry.
