The South Carolina Court of Appeals issued a significant ruling on October 21, 2026, regarding a divorce agreement between Thomas Tanis and Susan Tanis. The court found that Susan Tanis violated the terms of their 2011 divorce agreement concerning their two children. This decision affects both parents and highlights the importance of adhering to court orders in family law cases.

The case began when Thomas Tanis filed a petition in April 2023, claiming that his ex-wife, Susan Tanis, had willfully violated their divorce agreement. The agreement, established in 2011, granted Susan decision-making authority over their children's matters but required her to keep Thomas informed about significant developments in their lives. The court's ruling is crucial as it underscores the responsibilities of parents under divorce agreements and the consequences of failing to comply.

Thomas and Susan Tanis divorced in 2011, and their divorce agreement was formalized by a family court order on November 14, 2011. The agreement stipulated that both parents would have access to their children's records and be kept informed about important events in their lives. It also emphasized the need for mutual support in maintaining a positive relationship between the children and both parents.

In April 2023, Thomas filed a petition alleging that Susan violated the agreement by failing to notify him about their older child's use of birth control, enrollment in counseling, and participation in a scholarship ceremony. Instead of responding to the petition, Susan filed a motion for a more definite statement. The family court issued an order on May 8, 2023, during the hearing for Thomas's petition.

Thomas's case focused on three main allegations against Susan: failing to inform him about their child's birth control, not notifying him about the counseling, and not informing him about the scholarship ceremony. He argued that these actions violated the divorce agreement's requirement for timely communication regarding significant developments in their children's lives.

In response, Susan presented evidence of Thomas's behavior, claiming it had negatively impacted their children and contributed to the alleged violations. The family court was particularly concerned about a video in which Thomas was heard shouting at one of the children. Despite acknowledging that Susan had violated the agreement, the family court declined to hold her in contempt, citing the doctrine of unclean hands, which prevents a party from seeking relief if they acted unfairly in the matter.

The family court explained that Thomas's conduct was so egregious that it could be blamed for the violations and that it precluded him from seeking redress. Thomas subsequently filed a motion for reconsideration, which the family court denied, leading to his appeal.

In its ruling, the Court of Appeals reversed the family court's decision to not hold Susan in contempt. The court stated, "We hold that Thomas's conduct was not sufficiently connected to the three violations that are before this court on appeal." The judges emphasized that Susan's actions were willful violations of the divorce agreement, which required her to keep Thomas informed about significant developments in their children's lives.

The court clarified that the family court's use of the unclean hands doctrine was inappropriate in this case. It noted that while Thomas's behavior was indeed problematic, it did not justify Susan's failure to notify him about the birth control, counseling, and scholarship ceremony. The ruling emphasized that each parent's obligations under the divorce agreement must be upheld, regardless of the other parent's conduct.

The Court of Appeals ordered the family court to determine appropriate sanctions for Susan's violations and reassess any attorney fees awarded. The judges highlighted that the family court's previous refusal to find Susan in contempt was not justified, as there was no sufficient connection between Thomas's behavior and Susan's violations.

This ruling has significant implications for future family law cases in South Carolina. It reinforces the idea that parents must adhere to the terms of their divorce agreements and that violations can result in legal consequences. The decision also clarifies the limits of the unclean hands doctrine, emphasizing that it cannot be used to excuse violations of court orders.

Moving forward, the family court will need to address the appropriate sanctions for Susan's violations of the divorce agreement. This case serves as a reminder for parents navigating divorce agreements to communicate effectively and fulfill their obligations to ensure the well-being of their children.

As of now, it is unclear whether the ruling can be appealed further. The court filing did not specify any related cases pending.
