There will be little or no disruption to services provided by the Console charity.
Brian Higgins, CEO of Pieta House, says the services previously provided by Console will be taken on by the suicide prevention charity.
Mr Higgins adds the Console centre in the Catherine McAuley building in Balloonagh is still operating, and all staff have been given three-month contracts.
The intention is to keep the two charities separate for the foreseeable future, as Pieta House deals with those who are feeling suicidal while Console deals with the bereaved.
Mr Higgins says it will take some time to regain the trust of the Irish public, and he believes the government can help through proper oversight of the charity sector.
