First gay marriages likely in August
Ireland's new laws on gay marriage will be enacted by the end of July.
After the country's resounding support in a world first vote, Justice Minister Frances Fitzgerald said she was working to fulfil the wishes of same-sex couples who want to wed as soon as possible.
With the standard three month notification to register a wedding day, the first ceremonies are likely in the autumn.
"The Irish people have chosen decisively to extend the right to marry to same-sex couples," Ms Fitzgerald said.
"I am particularly proud that the right to marriage equality will now be enshrined in our Constitution as a result of a popular vote. I would like to compliment all of those who voted and who campaigned on both sides for what was a passionate and yet civilised referendum campaign."
"I am very conscious that many couples will want to get married as soon as possible. I am working to make that happen."
Government officials are currently drafting the Marriage Bill to reflect the vote and constitutional change.
It is expected to be finalised in June when it will go to Cabinet before passing through both houses of the parliament in Dublin before the summer recess.
The new laws will also give same-sex couples who have already made plans to enter a civil partnership to switch their notification to a planned marriage.
The Minister stated: "This means that couples who have already registered their intention to enter a civil partnership will be instead able to get married once the law is enacted on the basis of the same registration of intent."
The referendum on gay marriage saw Ireland make history as the only country in the world where the reform was backed by popular vote.
