u/Responsible-Key-5106

I'm in Indiana and have a question about how child support works after a custody modification.

Hypothetical numbers for simplicity:

• Mother currently owes Father approximately $5,520 in child support arrears from an existing support order.
• In the future, if parenting time were modified to 50/50, the Indiana Child Support Guidelines would likely result in Father owing Mother approximately $115/week in ongoing child support due to their income disparity.

My question is: What typically happens in this situation?

Would:

1. Father immediately begin paying Mother $115/week while Mother separately continues paying her arrears?
2. Would the court order Father's new support obligation to be credited against Mother's existing arrears until they're satisfied (roughly 48 weeks in this example), with Father's payments beginning afterward?
3. Is this something the court can do only if both parties agree, or can the court order it over objection?

For purposes of this question, please assume:

• The arrears are owed directly to Father, not to the State.
• I'm not referring to any other judgments or reimbursement orders - only child support arrears.
• The custody modification and child support modification would occur in Indiana.

I'm mainly trying to understand how Indiana courts typically handle this situation and whether an offset is legally permissible or whether the two obligations are generally treated completely separately.

Thanks!
