Why its good decision to have husband's name in property ?

Hello, I am buying a house in Gujarat, India. I am a female living in the USA, and it is an under-construction property. I am paying for it from my own account. However, my brother-in-law insisted on adding my husband's name on the property as well, so the initial paperwork has his name too. If we divorce in the future, do I have to give a share to my husband, even though he has not paid anything? Why did my CA brother-in-law insist on adding my husband's name as a co-owner? Can I add my minor children as co-owners?
