The Iowa Court of Appeals has upheld a lower court's decision regarding the custody of two young daughters in the case of Amber Dawn Aden v. Austin Lee Sparks, No. 25-1827, filed on August 19, 2026. The ruling affects the lives of the children involved and clarifies the standards for modifying custody arrangements in Iowa.
Amber Aden and Austin Sparks are the parents of two daughters, born in 2018 and 2019. Although they have never been married, the couple reached a joint custody agreement in 2021. Under this agreement, Amber was granted physical custody, while Austin was given visitation rights. Austin's visitation was set for every other weekend and included a holiday schedule and summer visitation. The agreement also stated that Austin would pay $1,330 per month in child support.
In late 2024, Austin filed a petition to modify the custody decree, claiming significant changes in circumstances. He alleged that Amber had failed to communicate about the children and had attempted to alienate them from him. Austin requested primary physical care or, alternatively, joint physical care. He also sought additional parenting time and a modification of his child support obligation. Amber opposed the modification, arguing that no significant changes had occurred and requested an increase in child support.
The case was brought to trial over two days in July 2025. During the trial, Austin testified that he had transitioned to a dispatcher role in his trucking company, allowing him to work primarily from home. He also moved to Pocahontas, where he now lives with his fiancée and their baby. Amber, on the other hand, has remained in the same home and has worked for the same employer for five years, splitting her time between home and the office.
After reviewing the evidence, the district court denied Austin's requests for modification of custody or visitation. Instead, the court increased his child support obligation to $1,802.75 per month. Austin subsequently appealed the decision.
The Iowa Court of Appeals reviewed the case de novo, meaning they examined the entire record and made their own determination. The court noted that Austin did not challenge the denial of primary or shared physical care or the child support modification. His sole claim was that the district court erred by not finding a change in circumstances that would warrant additional parenting time.
Austin argued that his new work-from-home situation, the limited parenting time he had under the original decree, and the need for his children to bond with their new sibling justified a modification. However, the court found that Austin had not met his burden of proof. The court stated, "The parties represent that text messages are their only communication. If that is the case, all of Austin’s alleged requests for additional parenting time should be contained within the text messages." The court concluded that Amber had offered more time than Austin had requested over the past four years.
The court also pointed out that Austin's claims regarding his job change and the birth of a new child were not unforeseen changes. They stated, "Parents who separate often go on to have new relationships and have additional children." The court emphasized that while Austin's work situation had changed, it was not sufficient to justify a modification of visitation.
Ultimately, the court affirmed the district court's decision, concluding that Austin had not demonstrated a material change in circumstances since the original decree. The court also declined to modify the decree to add a right of first refusal for Amber when she was not with the children, agreeing with the lower court's assessment that Amber had not frequently made childcare arrangements without offering time to Austin first.
This ruling has implications for future custody cases in Iowa, particularly regarding the standards required to modify visitation and custody arrangements. The court's decision reinforces the importance of demonstrating a material change in circumstances and the best interests of the children involved.
Looking ahead, Austin has the option to appeal this decision to the Iowa Supreme Court. However, details regarding any related cases or further actions have not been provided in the court filing.
