You cannot vote unless you are on the Register of Electors. Have you checked recently? To get on the supplement to the register you must be 18 years or over on polling day and be ordinarily resident at the address at which you want to register. If you are on the register and have moved address recently, you may apply to get on the supplement at your new address.
Irish Citizens can vote at the Referendum.
Supplement application forms are available from City, County or City and County Councils and on-line at www.checktheregister.ie. Completed forms must be received by the registration authority for the area in which you reside by Tuesday 8 May 2018.
Your application must be signed in the presence of a member of the Garda Síochána from your local Garda Station or, if you establish in writing that you cannot do so, then in the presence of an official of your City, County or City and County Council. In either case, photographic and other identification may be required and should be brought with you.
If neither option is viable due to a physical illness or physical disability, the application form must be accompanied by a medical certificate.
Supplement to the Postal and Special Voters Lists.

Application forms are available from City, County or City and County Councils.
