As far as I know NS has not paid any fine which was imposed when he was found guilty.
This is an old video from 2018 so I was expecting the property to have been sold off by now but it looks like the Government and law enforcement is indeed incompetant since neither has NS paid the fine of Rupees 1.5B nor has the Government confiscated and sold any of his properties. Pakistani law is totally useless it seems since any serious country would have gotten the money in any way possible by now.
The Government needs to show its voters that they are really going after the criminals. If they are not getting the money back then they should tell everyone.
