The process of maintenance in Spain implies that it is necessary to ensure that minor children or those who have not yet achieved their economic independence receive an adequate financial contribution for their maintenance and education. This process begins with the submission of an application to the family court, which sets out the family and economic circumstances that justify the need for maintenance.

Once the judicial process has begun, a hearing is scheduled before the judge, where both parties present their arguments and evidence. During this stage, financial documents, witness testimony and other elements can be presented to support the arguments of each party. The judge, in his assessment, takes into account the best interests of the child as a fundamental principle.

The determination of maintenance is done by considering a number of factors, such as the income and expenses of both parents, as well as the specific needs of the children. The aim is to establish an amount to ensure adequate maintenance and education for children, taking into account their well-being and comprehensive development.

Once all the evidence and arguments have been evaluated, the judge issues a judgement setting out the amount and conditions of the maintenance. This sentence is binding on both parties and may be amended in the future if economic or family circumstances change. In the event of a failure to comply with the pension, there are legal mechanisms for its implementation and for ensuring the right of children to receive the necessary financial support.
