Surety liability follows the court's orders, not the label on its riders
Surety bonds. The surety's liability derives from the respective bond agreement and from the court rulings that modify the secured obligation.
Official heading (Spanish): PÓLIZAS DE FIANZA. LA RESPONSABILIDAD DE LA AFIANZADORA DERIVA DEL CONTRATO DE FIANZA RESPECTIVO, ASÍ COMO DE LAS RESOLUCIONES JUDICIALES QUE MODIFIQUEN LA OBLIGACIÓN GARANTIZADA.
The ruling
A direct amparo suspension was secured with a surety bond, later reduced and then increased, but the rider for the increase was labeled a reduction. In the damages incident, the surety argued it was liable only for the last reduced amount. The Collegiate Circuit Court held that its liability derives from the agreement and from the rulings modifying the obligation, under article 166 of the Insurance and Surety Institutions Law.
Our take
This is good news for parties receiving a court bond: an error in how a rider is labeled does not reduce the coverage the judge ordered. For the party buying the bond, the message is the reverse: the surety can recover from its principal whatever it pays, so a misissued rider protects no one. In our experience, these errors go unnoticed by everyone, as happened here. Check each rider against the order that triggered it before filing it.
What to do
- Check each bond rider against the court order requiring it before filing.
- If you are the bond beneficiary, confirm amounts and descriptions match the order.
