The issue involves more than 30 lawyers and agencies across Canada that help survivors fill out forms needed to file for compensation.
Dan Shapiro, chief adjudicator of the Independent Assessment Process, says there's evidence to suggest some survivors are being charged too much for that work.
He says that could deprive survivors of the full benefits they are entitled to under the $5-billion Indian Residential Schools Settlement Agreement.
Lawyers for the chief adjudicator were in Manitoba Court of Queen's Bench last week seeking an order that claimants should have to pay only approved legal fees.
The ruling involving a Winnipeg lawyer and a form-filling company is pending and could be applied across the country.
