SAME-SEX parents will officially be able to register both their names on their child's birth certificate form May 2020.
The new regulations are due to be signed in by Health Minister Simon Harris later today.
It follows the Equality for Children campaign which highlighted the limbo that gay couples face in the legal parenting of their children.
Up until now, an anomaly meant that some parental rights for same-sex couples were afforded to only one parent, and would usually favour the child's birth mother.
But campaigners described the arrangement as "perilous" in the event of bereavement and illness.
The minister confirmed he would today sign regulations to commence Sections 2 and 3 of the Children and Family Relationships Act.
These sections allowed for parentage through donor-assisted human reproduction and were technically put in place in 2015, but a loophole in the legislation meant that these clauses had yet to be properly enacted.
Mr Harris will meet a number of the families involved and sign the regulations in their presence. This will allow same-sex parents to register both their names on their child's birth cert from May 5, 2020.
Mr Harris has also agreed to examine other areas of law reform required to support all LGBT families, according to the Irish Independent.
He said he would be "committing to work with them on these issues in coming weeks and months".
"When I met with LGBT families a number of weeks ago, they pointed out the impractical realities of our current laws," he said.
"While we know some of their issues will be addressed through the Assisted Human Reproduction Bill, there are areas that require some consideration.
"I have some proposals as to how to look at these matters but I want to discuss these with the families first and hope to make some progress on this next week."
