A marriage license in Indonesia is only allowed to be granted to a man and woman from age 19 and above. The aim is to prevent early marriages which are very vulnerable to divorce due to the psychological immaturity of the couple. For example. Kotagajah Timur was observed to have a common case of divorce among underage people that married due to pregnancy outside of marriage. https://www.mariameetsanna.com/product-category/t-outliner/
