The garda whistleblower Maurice McCabe has settled High Court proceedings the family took against the State.
The amount that the State agreed to pay the McCabes has not been disclosed.
"All the litigation has been resolved to their satisfaction. Maurice and Lorraine and their family are happy to be able to move on now and leave all of this behind them," the family's solicitor Sean Costello told RTÉ.
RTÉ understands that the settlement was reached yesterday following negotiations between the State and the McCabes' legal team, which was led by former attorney general Michael McDowell.
The negotiations were in relation to 11 separate claims.
Six of those claims were in relation to Tusla and the Health Service Executive and were filed in the names of Maurice and Lorraine McCabe and four of their children.
Tusla and the HSE mishandled a false claim of child rape against Mr McCabe.
Tusla opened files in the names of four of their children, which stated that they were at risk from their father.
The Disclosures Tribunal criticised the child and family agency for "astounding inefficiency" for giving the erroneous allegation an "afterlife".
It is understood that the McCabes sued for breach of privacy, misfeasance in public office and malicious falsehood in relation to those errors.
There was a personal injuries claim for bullying and harassment dating back to Mr McCabe's service in Baileboro Garda Station.
There was also a defamation case in relation to a letter that was circulated to garda stations in 2011 in the wake of an internal garda inquiry into allegations of garda malparactice made by the garda whistleblower.

The Disclosures Tribunal report in quotes
Although some of his allegation had been upheld, the letter stated that "no systemic failures had been identified in the management and administration of Baileboro Garda district and no evidence was found to substantiate alleged breaches of procedure".
The letter, signed by the now retired Chief Superintendent Colm Rooney, went on to state: "I would like to congratulate all members who served in Baileboro. The findings of the Assistant Commissioner vindicate the high standards and professionalism of the District force in Baileboro."
There were also claims in relation to the actions of the former garda commissioner Martin Callinan.
Mr Callinan was found to have engaged in a "campaign of calumny" with his former press officer Superintendent David Taylor to discredit the whistleblower.
The McCabes sued for misfeasance in public office, malicious falsehood, negligent infliction of emotional suffering, breach of duty and infringement of constitutional rights.
