Stamp Duty

What do you mean be stored or vaulted, the stamp duty is applicable in the state where the document is executed.

I have executed the documents in Gurgaon with stamp duty as applicable in that Region, but now I have to shift my documents from Gurgaon to Mumbai. In such case do I need to pay the stamp duty on the same document as per Bombay Stamp Act. or I can just store the document in Mumbai withou paying any Stamp duty?

same document cant be executed twice. if u wanna store that document any where in india u may store. but u cant use

Your query is not clear as to what is the document you created and talking about? But generally speaking, mere keeping of a registered or stamped document, it is not necessary to re-register it or re-stamp it wherever you go nevertheless it has legal value.

its not matter where u r stored document.
