repeal provisions related to the shared parenting child support cross credit.

SB 163 repeals South Dakota's "shared parenting child support cross credit" provision (§ 25-7-6.27), which previously allowed courts to adjust child support payments when children spent roughly equal time (180+ nights/year) with both parents. This repeal removes a specific calculation method that would reduce payments for noncustodial parents in equal-sharing custody arrangements by offsetting each parent's share based on income and parenting time. The bill directly affects parents in shared parenting custody cases who previously qualified for this adjustment. After this repeal, child support will be calculated using standard formulas without this cross-credit adjustment, meaning parents in equal-sharing arrangements will no longer have their payments reduced through this specific mechanism.
