The Plymouth Argyle Fans Trust is to meet the club's owner James Brent next week to discuss plans to take a 20% stake in the club.
When Argyle's new board was unveiled in January, Brent also outlined a plan for the Trust to become part-owners.
The Trust was instrumental in bringing the businessman, who saved Argyle from administration, to Home Park last year.
"One of our prime objectives is to secure a stake holding in the club," Trust vice-chairman Tim Chown said.
"But we need to know what powers we may or may not have and what James Brent will be offering us for the 20%," he told BBC South West.
"We're very happy with what he's doing so far, but need to understand the details."
The Trust has yet to find out the purchase price but is already exploring a number of options as to how it could raise money and has been given until the end of September to decide whether or not to take up the shareholding.
"The Trust played a big part in saving the club and we would be looking for a generous offer, but until we speak, I no idea what that offer could be.
"Whilst the club doesn't have many assets, as a brand it certainly has a value," Chown added.
