The parent living with the children always spends more
Cuando una familia se rompe en España, la ilusión del reparto equitativo choca con una realidad jurídica más compleja y, para muchos, más injusta. La ley no divide los gastos de los hijos a partes iguales, sino que los distribuye según ingresos, custodia y necesidades reales del menor. En este equilibrio imperfecto, quien convive a diario con los hijos suele cargar con más responsabilidad económica de la que el sistema compensa, una asimetría que refleja desigualdades más profundas en la sociedad española.
- La creencia de que los gastos de los hijos se reparten al cincuenta por ciento es uno de los malentendidos más extendidos entre quienes atraviesan una separación en España.
- El progenitor custodio absorbe los gastos cotidianos —alimentación, colegio, sanidad, suministros— que superan con creces lo que cubre la pensión recibida.
- Cuando ese mismo progenitor es también el de menor salario, la desventaja se duplica: más carga diaria, menos recursos para afrontarla.
- Incluso en la custodia compartida, los tribunales suelen imponer la pensión al progenitor con mayores ingresos, generalmente el padre, reproduciendo la brecha salarial de género.
- El Consejo General del Poder Judicial fija en 150 euros mensuales el mínimo orientativo, pero los expertos advierten que ninguna pensión cubre la totalidad real del coste de criar a un hijo.
Cuando una separación llega a los juzgados de familia en España, muchos padres y madres descubren que la lógica del reparto igualitario no tiene respaldo legal. Según Rocío Galván, abogada del Bufete Capitol, la pensión de alimentos no divide los gastos a partes iguales, sino que se calcula a partir de tres variables: los ingresos de cada progenitor, el coste real de los hijos y quién ostenta la custodia principal.
El esquema habitual establece que el progenitor no custodio paga una pensión al custodio, quien a su vez asume la mayor parte de los gastos del día a día. Esto genera un desequilibrio inmediato: quien comparte techo con los hijos gestiona facturas, compras, visitas médicas y transporte escolar con recursos que la pensión no alcanza a cubrir del todo. Si además ese progenitor es el de menor salario, la desventaja se vuelve doble.
Ni siquiera la custodia compartida resuelve el problema. Aunque los hijos pasen el mismo tiempo con cada progenitor, los tribunales españoles suelen asignar la obligación de pagar al que más gana, que en la mayoría de los casos es el padre, un reflejo directo de la brecha salarial que persiste en el país.
El Consejo General del Poder Judicial ha establecido tablas orientativas con un mínimo de 150 euros mensuales para situaciones de escasa capacidad económica. Pero Galván es clara: incluso en ese umbral mínimo, el progenitor custodio siempre gasta más de lo que recibe. La pensión alimenticia no es una división real de la responsabilidad económica, sino una contribución parcial a un coste que no se reparte nunca del todo.
When a marriage with children ends in Spain, few things confuse separating parents more than figuring out who pays what for the kids. The assumption most people carry into family court is straightforward: split the costs down the middle. But that's not how Spanish law actually works, according to Rocío Galván, a lawyer at Bufete Capitol.
The reality is messier and, for many custodial parents, considerably less fair. Child support in Spain doesn't divide evenly between mother and father. Instead, it hinges on three concrete factors: how much each parent earns, what the children actually cost to raise, and who has primary custody. The standard arrangement, Galván explains, is that the parent who doesn't live with the children most of the time pays support to the one who does. The non-custodial parent writes a check; the custodial parent receives it and absorbs the bulk of daily expenses.
This creates an immediate imbalance. The parent sharing a home with the children—managing school runs, buying groceries, paying utilities, covering medical bills—typically spends far more than the support payment covers. The gap widens considerably if that parent also happens to earn less than their ex-partner. They're simultaneously bearing the heavier financial load and receiving less income to meet it. "The parent living with the children every day, present for most of their time, carries expenses that exceed what the other parent's payment can cover," Galván notes. If that custodial parent is also the lower earner of the two, they end up doubly disadvantaged: more responsibility, fewer resources.
Even when custody is shared equally—children spending the same number of nights with each parent—the fifty-fifty myth persists and fails. Spanish courts typically assign support payments to whichever parent has the higher income. That's usually the father, a reflection of the country's persistent wage gap between men and women. Equal time doesn't produce equal financial obligation.
To establish these payments, Spain's General Council of the Judiciary has created guideline tables. The floor is set at 150 euros per month, applied when the parent being ordered to pay has little to no income. But even at that minimum, Galván emphasizes a hard truth: the custodial parent always spends more. The mythical fifty-fifty split doesn't materialize in practice, not even at the lowest end of the scale. A child costs what a child costs. A support payment is simply a partial contribution toward that cost, not a true division of responsibility.

Why does Spanish law structure child support this way instead of just splitting everything equally?
Because the law tries to account for reality—one parent is actually there every day, buying the food, paying the rent, taking time off work when someone's sick. That parent's costs don't pause just because they're also the custodial one. The law recognizes that, but the payment rarely catches up to the actual expense.
So a parent with custody and a lower salary is essentially penalized twice?
Exactly. They're doing more of the work and have less money to do it with. The system tries to correct for that through support payments, but the minimum of 150 euros doesn't come close to covering what a child actually needs.
What about shared custody? Does that change the dynamic?
It should, theoretically. But courts still look at who earns more and order that person to pay. So even when time is split equally, the financial obligation isn't. The wage gap means it's usually men paying women, even when both are equally present in the child's life.
Is there a way for custodial parents to protect themselves financially?
The guidelines exist, and lawyers can argue for amounts above the minimum based on actual expenses. But the system assumes the custodial parent will absorb costs the support payment doesn't cover. It's built into how the law thinks about parental responsibility.
Does this happen in shared custody cases too?
Yes. The courts don't see equal time as equal financial responsibility. They see income disparity and order the higher earner to contribute more, regardless of how the children's time is divided.
