What Is Shared Parenting Expense Sharing?

Shared parenting expense sharing is a method for divorced or separated parents to divide ongoing child-related costs fairly. Each parent contributes proportionally based on their income and custody time. This includes housing, food, clothing, education, healthcare, activities, and transportation costs for the child.

The system ensures that both parents support their children equitably. The income-based obligation reflects each parent's ability to pay, while custody adjustment accounts for direct costs incurred during parenting time. A net transfer payment balances the difference, ensuring fair contribution from both parents.

Shared Parenting Expense Formula

Total Shared Costs = Housing + Food + Clothing + Education + Healthcare + Activities + Transportation + Other

Income Ratio = Parent Income / Combined Income

Income-Based Obligation = Total Shared Costs × Income Ratio

Custody-Adjusted Obligation = Income-Based Obligation × (Custody % / Total Custody %)

Net Transfer Payment = Parent 1 Adjusted Obligation - Parent 1 Direct Custody Obligation
