I failed to change my IC within 28 days, can I renew my Deed Poll?

If the person who changed his name has a Singapore identity card (IC), he must change his name in his IC without 28 days from the date of the Deed Poll. If he fails to do it, the Deed Poll lapses, and he will have to do a fresh Deed Poll and pay a fee for the new document. He cannot extend the validity of the Deed Poll.
