Clubs will have to vote for the proposed restructure of the Scottish Football League by April 19.
The Scottish Football Association has set the date for all clubs in the SFL to put their forward their votes by the aforementioned date with Premier League clubs to vote on the proposed 12-12-18 structure, which would split into 8-8-8-18 after 22 games, by April 15.
11 of the 12 top flight clubs will need to vote yes whilst 22 of 29 SFL clubs will also have to vote in favour for the plans to go ahead.
An SFA statement read: "The Scottish FA facilitated a special meeting of the Professional Game Board at Hampden Park to establish both the current position and next steps from the Scottish Premier League and Scottish Football League in relation to the ongoing league reconstruction process.
"At the meeting - which also included representation from the SPL and SFL board of directors - a number of issues were debated openly in order to provide clarification and certainty on a number of issues that arose following the SFL members' meeting on 28 March.
"The Scottish FA's position on league reconstruction is clear: Scottish football requires urgent, radical change in its league structures as a first, essential step to rejuvenating the national game.
"To that end, in order to provide greater comfort to both sides, we have agreed to undertake a period of due diligence on behalf of both the SPL and SFL to provide independent verification of projected distributable revenue of any single league body."
