Obtaining a Deed Poll is just the first step in changing your name. Your lawyer will prepare your Deed Poll for you to sign in his presence, and by having a Deed Poll, your name has not changed until you notify the Immigration and Checkpoints Authority (ICA).
Your lawyer does not notify anyone, and the onus is on you to effect the change of your name in your identity card (NRIC) at ICA within 28 days from the date of the Deed Poll.
