La forma correcta del mandato familiar de mandarlo

For example:

Mi primo estudia medicina por mandato familiar, todos los miembros de la familia han seguido la misma carrera y no quiere defraudarlos, entonces sus padres han decidido mandarlo a la escuela de medicina.

Explanation:

Family mandates are impositions that come from the values and customs of each family, for example. “I will have to marry my girlfriend, because our family mandates prevent the relationship of living without marriage” or “I will study medicine by family mandate, all family members have followed the same career and I do not want to disappoint them.”
