Its surprisingly common, even in the UK I have experienced it, at a friends married the vicar referred to them as Mr and Mrs Mans first name Mans surname.
I’m from Baltistan and I’m a Gilgit, we’re technically administered by Pakistan. Where I’m from a mans name isn’t worth more than a womans and if a woman has a higher status then her husband and children all take her name so they inherit her status. In other areas of Pakistan it is very similar to Afghanistan but women are named on official documents. It also varies by religion.
There are a lot of Afghani refugees in Western Pakistan, due to Pakistan licking Afghanistans arse their essentially invisible, they’re not included on the census etc.
A major issue is that because women don’t officially exist once they enter a country they are basically trapped there as they do not have documentation unless they are owned by a very wealthy family on their husbands side.
So there is a big issue with men dumping their wives in Pakistan and then going back to Afghan so they don’t have to support them anymore, its particularly common if she hasn’t produced sons or if she becomes ill.
