Jack C. v. Tally C., 284 P.3d 13

2008 divorce: mother awarded sole legal custody and primary physical custody; father given conditions to return for modification.
2009-2010: father filed motion to modify for joint legal custody and increased visitation; master recommended, and the court largely adopted, maintaining mother’s custody but enlarging father’s visitation.
Custody investigator recommended shared physical custody in summer and joint legal custody, plus ongoing counseling and parenting classes; noted parental conflict and communication problems.
2008 divorce order required anger management and parenting classes; court delayed major custody change until after psychological assessment and progress in parenting classes.
Fall 2010 order: mother kept sole legal custody and primary physical custody; father received visitation on Thursdays and alternate weekends; no summer modification; no change explained for summer.
Jack appeals, contending errors in fact-findings, best-interests analysis, and lack of summer-visitation explanation; majority affirms, remands on summer-visitation reasoning.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Was the final order’s best interests analysis an abuse of discretion?	Jack argues that the court weighed factors improperly and relied on flawed findings.	Tally contends the court properly applied statutory factors and supported conclusions with substantial evidence.	No abuse; findings supported and best interests supported keeping mother custody with expanded father visitation.
Did the trial court err by not explaining the summer visitation decision?	Jack asserts lack of explanation for not modifying summer visitation.	Tally argues explanation not required beyond the record; discretion exercised is proper.	Remanded for a narrowly tailored explanation on summer visitation.
Did the court’s adoption of the master’s findings and its interpretation of AS 25.24.150(c) constitute an abuse of discretion?	Jack claims the court ignored important findings from 2008 and treated them as promises.	Tally maintains the court properly considered current circumstances and statutory factors.	No abuse; current circumstances and statutory factors properly applied.
