A councillor plans to become one of the first people to make a legal commitment to his partner on the first day gay weddings are allowed.
Cllr Paul Bacarra will commit to his long-term partner David Davies
Paul Baccara, who represents Talbot Green on Rhondda Cynon Taf council, will sign the register with his partner of 26 years David Davies in December.
The commitment ceremony will give them the same legal rights as a married couple.
Gay weddings have become possible under the new Civil Partnership Act.
The law comes into force on 5 December, but there is a 15-day period before any ceremonies can take place.
It creates a new legal relationship of civil partnership, which two people of the same-sex can form with the signing of a registration document.
The couple have been together since 1979 and are looking forward to reciting commitment vows to each other.
Mr Baccara, 47, said that the new rules were important for gay couples who want to show their commitment to one another.
"It means that David will become my next of kin," he said.
"I have been with my partner for 26 years and we need the same legal rights towards each other as a married couple has.
"It is very important to me because I have had two heart attacks and technically David could be left outside the decision of what happens to me if I become ill because he is not my next of kin."
The ceremony will be held at the Miskin Manor in front of around 60 guests on the day that they become legal.
"As an openly gay councillor, I felt it was important to do this because I feel so strongly about it." he said.
"I want to show the way forward.
"This [the Act] is well overdue but it is done now and I am delighted."
Mr Baccara's mother Mary Greedy and Mr Davies' friend Bryn Birleson will witness the signing of the register.
But Mr Baccara did raise concerns about the new civil partnerships.
"I just hope it won't become abused and that people take it seriously because it is serious," he said.
