At what age is a father legally required to support his child?

The correct age at which a father is legally required to support his child is 18 years old. This age generally signifies the point at which a child is considered an adult in many jurisdictions, making the obligation for parental support applicable until that age. Often, this is linked to the requirement for financial support, education, and care during the dependent years of a child's life.

While there may be variations depending on specific laws in different states or countries, 18 is commonly recognized as the threshold for mandatory parental responsibility. This legal responsibility includes fulfilling obligations such as child support payments, covering essential needs like food, education, and healthcare.

In contrast, ages such as 21, 16, or 25 do not align with the established legal frameworks for child support obligations, as they either surpass the typical age of majority or fall below it, which would not reflect the legal realities concerning the provision of support.
