As I am a celebrant and not a legal solemniser my services are purely ceremonial.
The first phase if you choose me to be your celebrant is the legal side.
This consists of giving your notice of intent to marry to the HSE Civil Registry Office no later than three months before your wedding.
They will need photo ID, Birth Certs, Proof of address and a payment of €200.
You will then need to make an appointment to return for a second time to your chosen HSE office (at no additional cost and only takes 8-10 minutes) to sign your legal marriage certificate with them.
You will also need to have two witnesses present and will be required to receipt legal vows.
You can choose to perform the legally binding phase before or after your wedding day.
