The Scottish Football League is on a collision course with the Scottish Premier League after insisting it can block top-tier plans for an SPL2.
Peter Donald will seek a meeting with the SPL
SPL chiefs argue that the agreement made when it was created allows for the addition of a second division.
But, following an SFL committee, secretary Peter Donald said: "It's our belief is that it's not consistent with the settlement agreement.
"We will be writing to the SPL seeking a meeting to debate the issue."
The SPL pays an annual fee to clubs in the First, Second and Third Divisions as part of the agreement that allowed them to breakaway.
There are suggestions that, should First Division clubs follow and form SPL2, they would no longer be entitled to a share of that £1.6m.
The only issues are the financial settlement and the timescale
Dundee chief executive Dave MacKinnon
But Dundee chief executive Dave MacKinnon told BBC Sport: "It's going to happen and I think a deal will be done.
"The only issues are the financial settlement and the timescale.
"A divorce can be acrimonious or it can be amicable.
"But, if lawyers get involved, like in any divorce, the less both parties will end up with."
MacKinnon insisted that, with the loss of television coverage of Division One and a league sponsor, clubs like his had to act to retain full-time football.
"This season we have one of the most competitive First Division races in many years," he said.
"The games are superb, but there isn't a platform to actually show them."
But SFL president John Smith questioned that argument.
"The TV deal was only worth £50,000 and we have until the end of the season to find a sponsor, so I think that is just a smoke screen," he said.
"I don't have any objections to change, but the dialogue has to be right.
"The 30 clubs met in April and the First Division clubs said nothing about this then.
"They produced a paper five weeks later, but I would have thought that they would have had a dialogue with their parent body about that.
"I'm sure I would have looked at it with some sympathy.
"But I have slowed down the procedure because it was moving too fast.
"We are trying to get the right structure and recognise that there are full-time clubs whose needs must be met."
