Cardiff has become the latest council to reject "golden goodbyes" for long-serving councillors as the deadline arrived for applications.
The scheme hopes to make way for a younger generation of councillors
The Labour-controlled county council voted unanimously against the scheme on Thursday.
Cardiff's decision means that 13 out of 21 councils have turned down Welsh Assembly Government plans to offer up to £20,000 to those who agree not to stand in next year's local elections last month.
Only one Welsh local authority, Gwynedd, has still to vote.
Despite opposition from all other parties, Labour Assembly Members voted to offer the pay-off to councillors who have served for sixteen years or more.
Thursday was the deadline for them to say if they want to take advantage of the payment.
The idea behind the scheme is to make way for a younger generation of councillors.
But following widespread criticism, many councils have said they will not implement it, including a number of Labour-controlled ones.
One pensioner from Cwmbran has collected a 2,000-signature petition against her local council's support of the idea.
Rosemary Watkins said she was disgusted that Torfaen Council had voted in favour of the scheme.
But its supporters say the plans will clear the way for a broader cross-section of people to take part in local democracy.
Cardiff Council is expected to vote against the scheme later, with Gwynedd councillors set to do the same next month.
