"No limits" denotes that there are no legal constraints on females marrying at the age of 17. Can marry with parental consent and/or under religious or customary law, which implies that females under the age of 17 can marry with parental approval and/or under religious or customary law. In addition, there is no minimum age for marriage under Indian law. The practice of child marriage - the marriage of girls below the age of 18 - remains common in many parts of the world, including India. It is widely believed that by preventing young women from getting married, they will be better able to care for their families when they do marry. However, this assumption has been called into question by some studies that have shown that younger wives are less likely to live longer than older wives. In India, where child marriage is most common, it is estimated that 30 million women between the ages of 15 and 19 were married during 2005-2015. Of these, 2 million were married before the age of 15 and 8 million were married between the ages of 15 and 19. According to the International Marriage Research Institute's (IMRI) Global Study on Child Marriages, every 1 out of 10 girls aged 15-19 was already married. This amounts to nearly 7 million children across the globe who were married before their 18th birthday during 2005-2015. Child marriages are illegal in India.
