If you live in Ireland and you are over 18, you CAN vote in local elections but you MUST be registered.
You can get the forms here https://www.voter.ie/
Just fill in the relevant form, get it stamped at your local Garda station (Bring ID & proof of address if you have it).
Post or hand deliver the Garda stamped form to the local authority before 5pm 7th May.
If you need any assistance, just drop me a message.
