Baja California’s state congress unanimously approved a reform to the Civil Code that allows children and adolescents to claim unpaid child support retroactively from birth, with no statute of limitations. The new retroactive child support law was introduced by Representative Michel Sánchez Allende and applies to all open and future cases in the state.
Under the reform, the right to collect back child support has no expiration date. A child can seek payments owed at any point during their minority. The law also covers pregnancy and delivery expenses, meaning a custodial parent can recover those costs as part of a retroactive claim.
A Gap in Enforcement
State data cited during the legislative session showed just how rarely judges had granted retroactive support under the old rules. Between 2021 and 2024, only 31 out of 645 paternity and child support cases resulted in a judge ordering retroactive payments. That is less than 5% of cases.
The state currently has 868 open files of unpaid child support. The majority of those cases were filed by mothers on behalf of their children. Data from INEGI (Mexico’s national statistics agency) shows that most single-parent households in Mexico are headed by women.
Gender-Neutral Language and Broader Scope
The reform also removes gendered language from child support obligations in the Civil Code. Previously, specific articles assigned support duties using terms tied to mothers or fathers. The new text uses gender-neutral phrasing, making the obligation apply equally to any parent regardless of gender.
Before this reform, Baja California’s Civil Code did not clearly establish the right to retroactive support. Judges had discretion but rarely exercised it, leaving many custodial parents unable to recover years of missed payments. The new law removes that ambiguity by codifying the right directly.
What This Means for Binational Families
For residents with family law matters in Baja California, the change could affect existing support orders and paternity proceedings. Parents in binational custody situations, where one parent lives in the U.S. and the other in Mexico, should consult a local family attorney to understand how the reform interacts with current arrangements. Recognition-of-paternity cases, common among binational families, may now carry retroactive financial obligations dating back to the child’s birth.
The unanimous vote in the state congress signals broad political support for the measure. This story was first reported by Jornada BC.
