Recent legal clarification reveals Colombian child support obligations aren’t determined by rigid formulas or fixed percentages of income. Law 42 of 2012 mandates judges apply a principle of proportionality when setting support payments. This means courts must balance the income of the paying parent against the actual, demonstrated needs of the child. The system prioritizes a case-by-case assessment, moving away from standardized calculations. This approach aims for fairer outcomes considering individual financial circumstances. The ruling emphasizes a focus on ensuring children’s necessities are met in proportion to the paying parent’s financial capacity. This ensures a more equitable distribution of financial responsibility.
