Child Support in Puerto Rico: Calculation, Payment, and Enforcement

Child support in Puerto Rico is handled primarily by the Administración para el Sustento de Menores (ASUME), which calculates, collects, and enforces support under mandatory guidelines that took effect in March 2024. Both parents share the legal duty to support their children, whether or not they were ever married, and one feature routinely surprises people moving from the mainland: the age of majority here is 21, so orders typically run several years longer than they would in a U.S. state.

How the Amount Is Calculated

The current guidelines, known as Reglamento 9535, use an income-shares model. The calculation combines the custodial parent’s net income, the non-custodial parent’s net income, and, when applicable, the net income of either parent’s current spouse. Each parent is then assigned a share of the total support obligation in proportion to their piece of that combined income.¹ The underlying premise is that the child should receive roughly the same level of financial support they would have received if both parents lived together.

The formula also folds in the cost of the child’s health insurance premium and any work-related childcare expenses. The number of children and the custody arrangement influence the final figure as well.

To keep the non-custodial parent from being pushed below subsistence, the guidelines calculate a “reserved income” based on that parent’s net income and number of dependents, with a floor of $615 per month. A support order cannot dip below that floor absent just cause.¹ A court or ASUME hearing officer can set an amount above or below what the guidelines produce, but the reasons for the deviation must be in writing.

How Long Support Lasts

Because the age of majority is 21, reaching 18 does not end a Puerto Rico support obligation. If an order is in place, the paying parent stays bound by it until a judge formally releases them; the child turning 21 alone does not cancel the order.²

Support can extend past 21 for an adult child pursuing higher education. The child must have started professional studies before turning 21, must be currently enrolled, and must show both academic progress and genuine financial need. Where a court grants the extension, the obligation continues until the child earns a professional degree or turns 25, whichever comes first.²

A paying parent can also petition to be released from the obligation when any of the following applies:

The paying parent or the child dies.
The paying parent’s resources have declined to the point where paying support would leave them unable to meet their own basic needs.
The child can support themselves through a trade or profession, or their financial situation has otherwise improved.
The child commits an act that would be grounds for disinheritance, or the child’s need for support is the result of their own misconduct.

Establishing Paternity First

Before ASUME can issue a support order, the child’s legal parentage has to be established. Puerto Rico law presumes both spouses are the parents when the parents are married. For unmarried parents, paternity is established either through voluntary acknowledgment or by order of a court or ASUME.³

A parent can voluntarily acknowledge a child born outside marriage through a paternity certificate filed with ASUME, without going to court. When paternity is disputed, a judge can order genetic testing on their own initiative or at either party’s request, and ASUME has independent authority to order testing in its administrative cases, which speeds things up.⁴ If the test comes back negative, the person who received support payments may be required to return them.³

Opening a Case

ASUME is Puerto Rico’s Title IV-D agency under federal law, meaning it provides establishment, enforcement, and modification services to all families, not only those receiving public benefits.⁵ Most cases start with an application filed directly with ASUME, which then schedules the conferences and hearings needed to review financial information and apply the guidelines.

A support order can also be obtained through the courts, which is more common when support is part of a divorce or when the case involves more complex legal disputes. ASUME’s administrative process is generally faster for straightforward matters, but either route produces a binding order backed by the same enforcement tools. Reglamento 9535 applies whether the order comes from ASUME or a court.⁶

To open a case, gather documents covering identity, income, and child-related expenses. That means a government-issued photo ID for yourself, the child’s official birth certificate, and Social Security numbers for both parents and the child. Both parents need to document income: pay stubs, W-2 forms, or filed tax returns for employees, and profit-and-loss statements or business records for the self-employed. Bring receipts for the child’s share of any health insurance premium and for childcare tied to work or job training, since the formula factors both in.

How Payments Move

Payments flow through a State Disbursement Unit (SDU) operated by ASUME and processed through Banco Popular de Puerto Rico. Employers served with an income withholding order send the deducted amounts to the SDU, which then pays the custodial parent. Non-custodial parents who pay directly, such as self-employed workers, can pay through ASUME’s website or by credit card, and ASUME’s mobile app lets parents with an active case check balances, view payment history, and make payments.⁷

What Happens If a Parent Doesn’t Pay

ASUME can take most enforcement actions administratively, without going back to court for permission, which tends to make collection faster than in many mainland jurisdictions.⁴

The most common tool is an income withholding order sent to the non-paying parent’s employer, who must deduct the support amount from wages and send it to the SDU. When there are arrears, ASUME can order an additional withholding of up to 30% on top of the current support amount.⁴

When wage withholding is not enough or not available, ASUME has other options:

Freezing and seizing bank accounts, retirement funds, lottery winnings, unemployment benefits, and workers’ compensation payments.
Placing liens on real and personal property, and forcing a sale to satisfy arrears.
Intercepting Puerto Rico and federal tax refunds to cover overdue support.⁸
Suspending driver’s licenses, professional licenses, and recreational licenses.⁸
Triggering passport denial: under federal law, once arrears exceed $2,500, the U.S. State Department will refuse to issue or renew a passport.⁹
Reporting the delinquency to credit bureaus.

Criminal Consequences for Willful Nonpayment

Willfully failing to pay child support in Puerto Rico is a criminal misdemeanor. If paternity is not in dispute and the parent is found guilty, the court sets a reasonable support amount and warns the parent that continued nonpayment may be treated as civil contempt. The court can suspend the sentence when doing so serves the child’s best interests; the point is to get payments flowing rather than to jail a parent who could otherwise be earning.¹⁰

Changing an Existing Order

An order can be modified when circumstances shift in a way that makes the current amount unfair. The guidelines define a substantial change in circumstances as an unforeseen variation in the personal or economic conditions that existed when the order was set. Common examples include an involuntary job loss, a disabling illness affecting either parent or the child, or a significant change in either parent’s income.¹

Even without a dramatic change, either parent can request a routine review every three years. ASUME or the court recalculates the obligation using the current guidelines and updated income figures, and if the result differs meaningfully from the existing order, the amount can be adjusted.¹

To request a modification outside the three-year cycle, file a petition with ASUME or the court that issued the original order. Bring documentation of the change: termination letters, medical records, updated tax returns, whatever supports the claim that the current order no longer reflects reality. The same income-shares formula and reserved-income floor govern the recalculated amount.
