The lawyers will give pro bono advice to the victims, to determine whether they could be successful in making a claim for compensation from one of the Law Society's two fidelity finds.
Milne (79) was jailed for more than eight years last month, and had earlier placed himself in bankruptcy; meaning there are no assets to sell to distribute proceeds to his victims.
Downie Stewart solicitor David Sim, who is a committee member of the Otago branch of the Law Society, is one of the six lawyers.
The other five lawyers are Alistair Paterson, Mike O'Neill from O'Neill Devereaux, David Robinson from Gallaway Cook Allan (also local branch Law Society president), plus solicitors from Dunedin-based Webb Farry and Anderson Lloyd.
Mr Sim said while there was a group of 11 claimants, more of Milne's total 35 victims might yet decide to join in the action.
The claims are not straightforward, as the claimants have to prove they lent their cash to Milne as a personal loan, as opposed to giving it to him as an investment, as the latter is not covered for compensation from the Law Society funds.
New Zealand Law Society Fidelity Fund rules were changed after a large 1990s fraud payout, which meant money placed for investment was excluded from the responsibility of the fund.
And the two fidelity funds cover different periods.
The first fund predates August 2008 and has no cap to the level of claim, but there are limitations if the money concerned was given as an investment.
The second fund, for claims after 2008, has a cap of $100,000.
Mr Sim said the next step was for the lawyers to ''divvy up the workload'' of looking into the individual claims by victims, then begin processing the claims.
Mr Sim said the lawyers were supplying advice free, but could go on to represent a client if a formal claim was made to the Law Society.
In September 2012, it was Mr Paterson who initiated an ''affected persons register'' to collate the names and extent of loans made to Milne.
Claims by the group could be started until Milne's case had been heard.simon.hartley@odt.co.nz
