An estimate based on a survey of solicitors representing former residents of industrial schools and orphanages reveals that fewer than half of all victims’ claims have been lodged with a redress board.

The survey was carried out by a C&AG team and suggests the total bill, including legal costs, could be €200m more than the Residential Institutions Redress Board estimated last month.

The board, in 18 months to June this year has received 3,763 valid applications and made 1,277 offers. The total amount offered was €98.8m, an average of €77,000 plus €16,000 in legal costs. Just six cases were ruled invalid.
