S.B. No. 629 amends the Family Code regarding the accrual of interest on overdue child support payments. The bill changes the interest rate on delinquent child support from six percent to three percent simple interest per year. This new rate applies to various scenarios, including delinquent payments, confirmed arrearages, and retroactive or lump-sum child support judgments. Additionally, the bill specifies that these changes will apply to child support payments due on or after January 1, 2026, while also addressing how interest will accrue on arrearages existing before that date.

The legislation also clarifies that any money judgments for child support rendered before January 1, 2026, will continue to be governed by the previous law, ensuring that the former interest rates remain in effect for those cases. The bill is set to take effect on September 1, 2025, allowing for a transition period before the new interest rates are implemented.
