1) I didn't understood - take 30 years title search. What do you mean by Title Search. Does that mean buyer need to have all details of 30 years of respective property? OR it's a deed title in the name of the seller and if he has the full right to sell it. Can a Lawyer help in verifying and validating those document ?
The title search is nothing but tracing of title to more than 30 years back to the present date, this can be done by moving an application before the registrar's office, this can be done by an advocate.
2) What if the Deed/Title is in hold with multiple people? Do we need clearance from all? If someone doesn't provide clearance can't we construct anything on that property?
If the property is jointly owned by several people then all the owners have to sign the registered sale deed in favor of the buyer.
3) Bank is providing 80% Loan for a property. So due diligence from bank can be considered ?
Legal adviser of bank will communicate to you the required documents in this regard.
4) Is there any portal online/offline to check background of Selling Agency?
You have to see and verify from their website about this.
