What Is Child Support?

Child support (also called maintenance) is the economic contribution that one parent pays to the other to cover children's basic needs: food, housing, education, health, clothing, and recreation. It's a legal obligation that doesn't cease even if the non-resident parent is unemployed.

How It's Calculated

In most Spanish-speaking countries, support is calculated considering:

  • Minor's needs: Real and reasonable expenses of the child
  • Obligor's income: Salary, capital income, real economic capacity
  • Recipient's income: The resident parent's economic capacity is also considered
  • Custody arrangement: In 50/50 shared custody, there may be no support or it may be smaller

What Ordinary Support Includes

Ordinary support usually covers:

  • Daily food
  • Basic clothing and footwear
  • Ordinary school expenses (materials, transportation)
  • Routine medical care
  • Housing (proportional)

Extraordinary vs. Ordinary Expenses

Extraordinary expenses (special medical intervention, school trip, new extracurricular activity) require prior agreement from both parents. Disagreement about what is "ordinary" and what is "extraordinary" is a common source of conflicts. A written agreement with concrete examples in each category prevents these disputes.

Payment Methods

Support can be paid in several ways:

  • Direct bank transfer (most recommended, leaves a record)
  • Direct payment of bills (utilities, school, insurance)
  • Deposit into a shared account for children's expenses

Family Bridge allows recording each support payment with date, amount, and receipt, creating a transparent history for both parties.

Non-Compliance and Consequences

Non-compliance with the support obligation has serious legal consequences in most countries: wage garnishment, tax refund withholding, passport restriction, and in some countries, criminal liability.

Modification of Support

Support can be modified when either party's circumstances change (significant income change, change in the minor's needs). It can be done by agreement or judicially.

  • child support
  • maintenance
  • alimony
  • legal
  • co-parenting
