While buying a resale property in a co-operative housing society, I have differing opinion on whether a "sale deed" is appropriate of a "deed of assignment" is appropriate. I consulted several people from legal profession and opinion seems to be divided with some saying Sale Deed is mandatory, some saying Deed of Assignment is ok and some even suggesting rather absurdly - "you tell us what you want and we will do that for you".
My question is - I am looking for specific guidance of whether I register my agreement with a Sale Deed or with a Deed of Assignment. Please can you guide.
