Changing your legal in Ireland
Through the current system, you can legally change your name and gender marker using the Gender Recognition Certificate once you are over the age of 18 and have the required documents.
This is the route I took to change my name around March 2022. I did not have the deed poll complete so I used some payslips and letters from any places I had that used my current name as proof of "use and repute".
The first step is to fill out the GRC1 form. When filling this out you will see " name to be shown on GRC". This is where you put in your new full name. To complete the form you will need it to be signed and witnessed by a public notary or commissioner for oaths. It costs roughly 10 euro and should be easy to find by googling either public notary or commissioner for oaths followed by your county. I recommend calling them to make sure they will do it before making an appointment. It should only take 5-10 minutes. Once all the information is filled in and signed, send the form along with your original birth certificate and as much supporting documents as you can to the address provided on the form. Once this has been processed, you should receive your gender recognition certificate in the post along with all the original documents you sent.
The next step is to send off for your revised birth certificate. This will make it a lot easier to update all your official details such as your passport, drivers license, pps card etc. To get this you will need to send off this form to register your new name and gender in the national registrar and also this form to receive your updated birth certificate. The birth certificate is €20 which can be paid in various ways outlined in the second form.
Once you have your GRC and revised birth certificate, you should be able to update your passport and any other official documents.
