Hello, I am selling my flat in Thane, Mumbai to a close family member. This is a resale and I own the flat in Thane. The society is registered, and all the documents including OC is available. My relative is planning to take a loan.
1) Do I have to first register the sale agreement before the buyer can apply for a loan? Do I have to again register the sale deed? Am I paying stamp duty twice?! What is the correct procedure? Can one of you expert lawyers please advice!!
2) What documents are needed before registering the flat?
Thank you so much for your help. If you are a lawyer practicing in Thane, Mumbai, pl also include your contact details.
