Up to 150 new jobs are to be created at the child maintenance service in Belfast.
Social Development Minister Nelson McCausland said the new positions, which are mainly at administrative officer level, would be within the eastern division.
The employment opportunities are part of a £3 million investment in the service.
Mr McCausland said the announcement was fantastic news for the local economy.
"Securing new jobs in the current climate is a challenge and it is testament to the hard work and dedication of staff in the Northern Ireland child maintenance service," he said.
"These are jobs which could have gone to one of the other service providers in Great Britain, but Belfast has come out on top by offering a quality service and value for money. I am delighted that my department is playing its part in boosting the local economy and securing much-needed local jobs."
The additional investment has been committed for at least two years and recruitment is already under way.
The Northern Ireland child maintenance service provides impartial advice to help separated and separating parents make informed choices about financial arrangements and help set up, arrange or collect child maintenance.
As part of a service level agreement, the Northern Ireland child maintenance service also provides services to clients in the eastern area of Great Britain.
