Moreira, Juan Antonio v. Velazquez Colon, Amneris, KLCE202500482

Juan Antonio Moreira (the father) petitioned for the court to determine the amount he allegedly overpaid in child support to Amneris Velázquez Colón (the mother), claiming there was a reduction in the child's living expenses after the mother moved in with a family member in late 2023.
The Court of First Instance (TPI) had previously reduced the child support provisionally in October 2024, but it was not clear that this reduction was to be applied retroactively.
Moreira argued he continued paying the original support although expenses (like rent and utilities) had allegedly lessened, thus creating an overpayment.
The TPI denied the father's request to compute the alleged overpayment and advised any claim for overpayment must be resolved via a separate, independent action.
The Appeals Court reviewed whether the lower court erred in refusing to quantify the alleged overpayment through certiorari.

Issue	Moreira's Argument	Velázquez's Argument	Held
Whether the TPI should quantify alleged support overpayments	Reduction in expenses justified proportionate reduction in support and required credit/repayment	No retroactive order on support absent extraordinary circumstances; prior payments made in accordance with existing order	No; the TPI correctly denied the request due to lack of demonstrated right and proper procedural forum
Whether a lowering of support can be applied retroactively	Reduction should apply from the date expenses decreased (i.e., when mother moved out)	Only in extraordinary cases; generally effective from court decision date, not before	No retroactivity unless exceptional circumstances shown
Whether proof of overpayment and its amount was sufficient	Court should determine amount owed based on circumstances	Overpayment not demonstrated; amount not established or adjudicated	No sufficient evidence of amount or right to repayment presented
Proper procedural mechanism for asserting an overpayment	Can be raised in the ongoing family law proceeding	Must be raised in an independent/ separate action	Independent action required to litigate this claim
