The Utah Court of Appeals has upheld a lower court ruling that favors the Christiansen Family Trust in a dispute over a strip of land adjacent to their property. The ruling, issued on November 5, 2026, resolves a long-standing disagreement between neighbors regarding the ownership of the Disputed Strip, which lies along the boundary line of their respective properties. The court's decision is significant as it reinforces the legal doctrine of boundary by acquiescence, which allows landowners to claim property based on long-standing use and recognition of a boundary.

The case, Christiansen Family Trust v. Haas Land & Livestock (Case No. 20251107-CA), began when Haas Land & Livestock, which acquired its property in 2021, attempted to assert ownership over the Disputed Strip based on a survey that indicated the land was part of its parcel. The Christiansen Family Trust, which has owned its neighboring property for at least seventy years, claimed that it had established the boundary through the doctrine of boundary by acquiescence, which requires evidence of mutual recognition of a boundary line over a period of at least twenty years.

The dispute escalated when Haas began removing a fence that had historically marked the boundary between the two properties. In response, the Christiansen Family Trust filed a lawsuit to quiet title to the Disputed Strip, asserting that they had continuously occupied the land and that Haas's actions constituted trespass. The case was heard in a bench trial, where the trial court ruled in favor of the Christiansen Family Trust, quieting title to the Disputed Strip and holding Haas liable for trespass.

During the trial, the Christiansen Family Trust presented evidence from multiple witnesses, including a former owner of the Haas property, who testified that her family had never claimed ownership of the land east of the fence. The trial court found that the fence had been in place for at least seventy years and that the Christiansen Family Trust had farmed and grazed livestock up to the fence during that time. The court concluded that there was mutual acquiescence in the fence line as the boundary between the properties.

Haas appealed the trial court's ruling, arguing that the evidence was insufficient to support the findings related to boundary by acquiescence and challenging the exclusion of video evidence that purportedly showed the fence in disrepair. The court ruled that the trial court's findings were supported by sufficient evidence and that the exclusion of the video evidence was not an abuse of discretion. Judge Ryan M. Harris authored the opinion, with Judges John D. Luthy and Amy J. Oliver concurring.

The court affirmed the trial court's ruling, stating, "the historic [f]ence line had become the boundary of the properties," and noted that the evidence showed that the Christiansen Family Trust had occupied the Disputed Strip in a manner that would give a reasonable landowner notice that the fence was treated as a boundary. The court also found that the trial court's determination of mutual acquiescence was supported by the testimony of witnesses who confirmed that the fence had long been recognized as the boundary line.

This ruling has implications for property disputes in Utah, particularly those involving boundary lines and the doctrine of boundary by acquiescence. It reinforces the importance of long-standing use and recognition of boundaries between neighboring properties. The decision may serve as a precedent for similar cases in the future, as it highlights the need for clear evidence of both occupation and mutual recognition of boundaries.

Looking ahead, it remains to be seen whether Haas Land & Livestock will seek further legal recourse. The court's ruling can potentially be appealed to the Utah Supreme Court, although details regarding any such plans were not available in the court filing. The case underscores the complexities of property law and the significance of historical use in determining land ownership disputes.
