Lengthy court proceedings in the territory's largest sexual abuse litigation have whittled down the number of plaintiffs.

But more litigants continue to come forward, keeping alive proceedings against the colleges.

Jason Parkinson, from Porters Lawyers, has represented more than 100 Canberra men in civil claims against the schools since 2007.

On Tuesday, he said the bulk of the claims had settled, the payouts remaining confidential.

But he said there were still ''more matters coming through''.

''We're looking forward to resolving them with the Marist Brothers and [Daramalan's] Missionaries of the Sacred Heart,'' Mr Parkinson said.

At a directions hearing in June, just six cases were left from the initial flood of claims sparked by publicity surrounding the abuse.

Most of the Marist cases related to convicted paedophile John Chute, also known as Brother Kostka.

In June 2008, Chute was jailed for at least two years, followed by a year of weekend jail, for molesting six boys at Marist College in the 1980s.

A second abuser, Paul Lyons, took his own life in 2000 after one of his victims went to police.

Lyons taught at Marist between 1976 and 1987, then at Daramalan from 1988 to 2000.

Mr Parkinson has previously said he believes there were as many as five abusers at Marist between the 1970s and 1980s.

Fairfax Media understands some settlements have included apologies but, earlier this year, a former Marist's request for a commemoration plaque was rejected.

Chute molested the boy during a dark room session and, earlier this year, the victim was awarded an out-of-court settlement.
