UIFSA – Child Support in NJ and Across the U.S.
May 1, 2026 | Written by: | Share
The Uniform Interstate Family Support Act (UIFSA) is a law adopted by all U.S. states to simplify the establishment, enforcement, and modification of child support orders across state lines. It mandates that only one state has jurisdiction to manage a case, preventing multiple conflicting support orders.
Key components of UIFSA include:
- "One Order" Rule: UIFSA provides rules for identifying a single "controlling order" for child support, streamlining enforcement.
- Interstate/International Reach: UIFSA allows state agencies to directly enforce support orders against parents living in other states or certain foreign countries.
- Registration of Orders: a support order from one state can be registered in another for easier enforcement, often through income withholding.
- Modification Limits: generally, only the state that issued the original order can modify it, unless all parties have left that state, or the parties agree to a different jurisdiction.
Recently, the New Jersey Appellate Division addressed UIFSA issues in a published decision of Bournes v. Harris. Whenever the Appellate Division publishes a decision, it warrants review.
In this case, the parties divorced in 2005 in the State of Texas. They had two children, born in 2001 and 2002, who were unemancipated at the time the Texas divorce decree was entered. In the parties' marital settlement agreement (MSA), which was incorporated into the decree, the defendant agreed to pay $600 per month in child support for ten months each year, August through May, and the plaintiff agreed to pay the defendant $100 per month for two months, June and July. Thus, the defendant's child support obligation was $5,800 annually. The MSA stated it was "intended to be the full and entire settlement and agreement" between the parties and "should be interpreted and governed by the laws of the State of Texas."
The defendant alleged that the plaintiff filed a child support enforcement action against him in New Jersey sometime in 2016, which the court granted in March 2016. The probation department enforced child support against the defendant as payor at $600 per month based on twelve months, or $7,200 annually, rather than $5,800 annually, as stipulated in the MSA. The defendant maintained he was not served with the motion and attempted to "rectify" the child support issue as a self-represented litigant but was unsuccessful.
In 2024, the defendant’s arrears were vacated and the case with Probation was closed. In 2025, the plaintiff appealed that decision.
On April 4, 2025, the judge held oral argument on the motions and entered an order partially granting the plaintiff's motion and denying the defendant's cross-motion. In his Rules 1:6-2(f) and 5:5-4(f) findings of fact and conclusions of law included with the order, the judge determined the May 17, 2024 order terminated the defendant's child support obligation retroactive to each child's emancipation date, but did not vacate the arrears he owed as of that date. The judge rejected the defendant's argument that he should not have paid child support because the children lived with him since 2016. The judge emphasized "the record is clear" and noted the defendant never made a "successful application to modify his child support obligation." The judge reasoned that the defendant essentially requested "an impermissible retroactive reduction in his child support." Accordingly, the judge ordered probation to reinstate the arrears in the defendant's account as of the date of termination of his child support obligation—December 20, 2020—and enforced repayment at the rate of $100 per week.
The defendant then appealed this decision.
For enforcement purposes, New Jersey may register a support order issued by an initiating tribunal in the current home state of the children. N.J.S.A. 2A:4-30.168. The registration process begins by one party filing a request to register the out-of-state order with New Jersey's Family Part. N.J.S.A. 2A:4-30. Pursuant to these statutes, the plaintiff filed and registered the Texas divorce decree in New Jersey in 2013. After registration, the defendant had the right to contest the validity or enforcement of the registered order by requesting a hearing within twenty days after notice of the registration. N.J.S.A. 2A:4-30.172(b)(2). Pursuant to N.J.S.A. 2A:4-30.175, "[c]onfirmation of a registered support order, whether by operation of law or after notice and hearing, precludes further contest of the order with respect to any matter that could have been asserted at the time of registration." "[T]he law of the issuing state[,]" rather than the law of New Jersey, continues to govern "the nature, extent, amount, and duration of current payments under a registered support order." N.J.S.A. 2A:4- 30.171(a)(1).
In this case, the Appellate Court determined that, consistent with UIFSA, New Jersey properly registered the child support order on July 16, 2013, as reflected in the probation's financial audit report. Although the defendant claimed he was not noticed, that was questioned by the courts, as the defendant had access to his probation account (or could or should have) through the years, which showed all of these details he claimed not to have known.
A quick reminder/primer on UIFSA is always important, especially if a client relocates to New Jersey with an existing court order from which he/she may be seeking relief/enforcement, etc., in the new jurisdiction.
Also in this decision, the court reminded us that there is a general prohibition on the retroactive modification of support. However, the statute's anti-retroactivity requirement has been construed to be inapplicable to a reduction of child support based on a child's emancipation.[1] While that is a blog post for another day, because child support modifications are generally not retroactively applied, understanding when to file is essential.
Interstate child support matters, emancipation, retroactivity, etc., can be complex and incredibly fact sensitive. Consultation with an attorney experienced in these nuanced matters is necessary to understand and preserve your rights.

Super. 70, 73 (App. Div. 1995) (holding the statute "does not bar the cancellation of child support arrearages which accrued subsequent to the date of the emancipation of the minor"); see also Mahoney, 285 N.J. Super. at 643 (emancipating and terminating child support for two children two years apart in age, with each emancipation effective retroactive to each child's eighteenth birthday and holding "[w]here there is no longer a duty of support by virtue of a judicial declaration of emancipation, no child support can become due").
