IrelandHow is maintenance for children calculated?
Child maintenance in Ireland is not calculated using a fixed formula; instead, the court decides the amount based on the child’s needs and each parent’s financial means under the Family Law Act 1995.
What the Law Says
The law does not prescribe a mathematical formula for calculating child maintenance in Ireland. Instead, it gives courts broad discretion to decide what is fair and reasonable in each case.
Under the Family Law Act 1995, a parent has a legal duty to maintain their child — meaning to provide for their proper upbringing, including food, clothing, shelter, education, and healthcare.
The court must consider all relevant circumstances when deciding how much maintenance should be paid. This includes the child’s age, health, educational needs, lifestyle, and any special requirements — as well as each parent’s income, earning capacity, property, and financial responsibilities to others.
There is no statutory percentage or income-based calculator. Maintenance orders are tailored to the individual family situation and can be varied later if circumstances change.
Statutory TextThe court shall, in determining the amount of maintenance to be paid by a parent for a child, have regard to all the circumstances of the case including, in particular, the income, earning capacity, property and other financial resources of the parent and the child's needs.
— Family Law Act 1995, s. 7 — Maintenance of children
What to Do
Gather full financial information: income, expenses, assets, debts, and childcare costs.
Try to reach an agreement with the other parent — written agreements can be made into court orders.
If agreement isn’t possible, apply to the District Court (for maintenance up to €500/week) or Circuit Court (for higher amounts).
Attend court hearings prepared to explain your child’s needs and both parents’ financial situations.
Review or apply to vary the order if there’s a significant change — e.g., job loss, new child, or increased education costs.
