for how many days the share application money can be kept with out allotment of shares?

Answer 1

When will the Share certificates / refund orders reach me?

In a public issue, you will be getting refund or share certificates after 40-45 days from the closing date of the issue. In a book building issue, you will be getting the refund/certificates in 30-40 days from the closing date. The Share certificates will also be mailed around the same time if you have got the allotment.
