a 1997 model registered in 2001, 4 years without regn documents
2001 regn without tax payment till 2019 ..wow how to stay invisible skip road side checks for so long.
The vehicle documentation need to be surgically verified before any expense.
if the vehicle was leased from Bank, it is NOT-possible to transfer it without clearance from Bank.
If there are any amount(s) - yes AMOUNTS actual installment plus the penalties - out standing towards bank that shall be cleared before applying for NOC / transfer.
bank will not issue NOC & Transfer letter to anybody but the person whose cnic / documentation is used for lease.
be careful
