One parent in the U.S., the kids in Mexico. Who decides where they live?

Patria potestad is parental rights — legal representation of the child, major decisions about school and health, administration of the child's assets, and the support obligation. Guarda y custodia is physical custody, meaning who the child lives with day to day. Both parents normally keep parental rights after a divorce even when only one has physical custody.

There is no automatic rule. The governing standard is the best interests of the child. Custody has historically defaulted to the mother in Mexican practice absent proof of unfitness, and current practice is framed around the child's interests. We cannot promise an outcome, but we will tell you honestly what weighs in a case like yours.

For most of the case, no. An attorney can act for you under a power of attorney signed at a Mexican consulate near you, and hearings can often be attended remotely. There are moments where a judge may want to see a parent, and we tell you well in advance if that applies to your case.

Service is handled by the court through its own officers, and when the other parent is outside Nuevo León it goes through the corresponding court or through international channels. It is usually the step that decides how long the case takes, so gathering address information early is the most useful thing you can do.

Mexico is a party to the 1980 Hague Convention on international child abduction, and the route starts by filing a return application with the U.S. Central Authority at the State Department, which transmits it to Mexico's Central Authority. These cases need counsel in both countries and they move slowly. Contact us and a U.S. attorney immediately — speed matters.

Yes, when the circumstances that were taken into account have changed. A modification is filed with the court and the change has to be proven. Bring the existing ruling to your consultation and we look at what has actually changed and whether it is enough to file on.

Children have the right to be heard in the case, and the judge weighs their opinion according to their age and maturity. But their opinion does not decide on its own — it is weighed alongside everything else under the best interests of the child standard.

No. Custody is who the children live with; support is the money that maintains them. A parent without physical custody is normally still obligated to pay support. Sometimes both are resolved in the same case or the same settlement agreement, and sometimes separately.

Yes. Rights and obligations toward children do not depend on whether the parents married. What does have to exist is legally established parentage. If the father is not legally recognized, a paternity case comes first, and we tell you that in the consultation rather than after you have paid for the wrong filing.

It is something that can be raised before the Family Court and it depends heavily on the specific case. It comes up often in these families, where grandparents in Mexico have been raising children whose parents are in the U.S. Tell us your situation and we tell you what can be filed.

Travel consent requirements depend on the airline, the border authority, and whether a custody order exists. We review what your specific trip requires and prepare the Mexican-side documents properly, rather than having you improvise a letter that gets rejected at the airport.
