The custom of a single wife to an entire family is still in force until the present time. This takes place in the Tibet region and some remote Indian regions.
On the night of the wedding, the older brother is the one who breaks the virginity of the bride, not because the bride married him or that the marriage contract is written with dignity, but because it is customary to do so.
There is no contract, but is agreed with the bride’s family orally.
When the bride gives birth to her first child, whether male or female, it is attributed to the brother most similar to him.
The strangest thing is that if he is similar to his mother, they consider the wife to be blessed and to be in the name of his mother, while all the brothers are considered to be his father.
