Same-sex parents will from May be able to register both names on their child's birth certificate.
The Health Minister confirmed he would today sign regulations to commence Sections 2 and 3 of the Children and Family Relationships Act on Monday, 4 November.
This will allow same-sex parents to register both their names on their child's birth cert from 5 May 2020.
It follows the Equality for Children campaign which highlighted the limbo that LGBTQ+ couples face in the legal parenting of their children.
Presently, most cases will only allow for one person in a same-sex relationship to be a legal parent. Campaigners have highlighted the crass and illogical nature of the law, especially in events of bereavement and illness.
Minister Harris has also agreed to examine other areas of law reform required to support all LGBT families.
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."
Despite today's progress, the above regulations do not cover LGBTQ+ parents who have children through a surrogate.
In theory, a woman who donates eggs to the surrogate will not be the name on the child's birth cert, despite boasting a biological connection.
A ban on anonymous sperm donation and the creation of a register for donor-conceived children will also come into effect shortly.
