2025 WY 97
Wyo.2025Background
- Parents divorced in 2021; district court awarded Mother primary custody and ordered a 15‑month transition to shared custody with required reunification therapy for Father.
- The transition to shared custody never materialized; DM (the child) remained with Mother and was estranged from Father before and after the divorce.
- In March 2023 the State obtained a temporary child‑support order reflecting the anticipated shared custody; in November 2023 Mother petitioned to modify custody, visitation, and support to reflect actual primary custody (seeking a $25,900/mo support recalculation, retroactive).
- Mother argued Father abandoned reunification and now lives in Arizona; Father countered that circumstances have not changed since the custody order and that he continues to attempt contact.
- Trial evidence showed Father still texts and calls (no substantive contact since 2019), DM is thriving academically and socially, and Mother did not present new evidence of abuse or show she substantially changed prior conduct that undermined the Father‑child relationship.
- District court found no material change affecting DM’s welfare and therefore declined jurisdiction to modify custody or support; Supreme Court affirmed for lack of abuse of discretion.
Issues
| Issue | Mother’s Argument | Father’s Argument | Held |
|---|---|---|---|
| Whether there was a material change in circumstances to reopen the custody order | Mother: Shared custody is not occurring (Father abandoned reunification and lives in AZ); custody should be modified to reflect Mother’s primary custody | Father: Circumstances are the same as when order entered; no material change; court lacks jurisdiction | No material change; trial court did not abuse discretion |
| Whether Mother’s relocation to Pinedale justifies modification | Mother: Move changed ability to maintain parenting plan and affected DM’s opportunities | Father: Move did not alter parties’ ability to follow orders or DM’s welfare | Move was minor and did not show impact on parenting arrangement or DM’s welfare |
| Whether Father’s residence in Arizona and reduced visitation justify modification | Mother: Father’s relocation and abandonment of efforts make shared custody infeasible | Father: He still attempts contact; residence evidence was not proven at trial | No proof Father moved; continued contact evident; not a material change |
| Whether noncompliance with the custody order or altered support harms DM’s welfare | Mother: Noncompliance and lower support have negatively affected DM’s welfare (financial and relational) | Father: DM is flourishing; noncompliance stems from preexisting estrangement and DM’s choice; no welfare impact shown | Noncompliance alone, and evidence of financial impact, did not show a change affecting DM’s welfare |
