Spirit of Shankly have written to Liverpool FC for clarification over Fenway Sports Group's current position as owners.
And the influential supporters' union say they expect to be part of any consultation process if new owners are on the agenda at Anfield in the future.
FSG are believed to be open to a sale and have enlisted the help of two major US banks in Goldman Sachs and Morgan Stanley to help them explore their options, according to a report on Monday in The Athletic.

The American owners confirmed in a statement sent to the ECHO on Monday that they "would consider new shareholders" if such a deal was in the best interests of the club, but a potential buyer is not thought to be imminent at this stage.
SOS signed a contract to establish the formation of a Supporters Board in August that aims to deliver meaningful fan representation at boardroom level while consulting with club officials over key strategic decisions at Anfield.
The 16-person group have been put together in an effort to ensure every key demographic of Liverpool supporters is represented with Spirit of Shankly member Joe Blott being nominated as the LFC Supporters Board chair.
And now SOS have confirmed they have written to the club in an effort to find more guidance over FSG's potential search for a buyer.
A statement read: "We have seen reports today that FSG have put Liverpool FC up for sale.
"Spirit of Shankly have written to LFC for clarification and will await a reply before making comment. We do, however, expect both the Supporters Board and SOS to be engaged in some part of the process so that supporters are front and centre of any sale and the first thoughts of prospective owners.
"We will keep you updated."
In a statement given to the ECHO on Monday, FSG said: "There have been a number of recent changes of ownership and rumors of changes in ownership at EPL clubs and inevitably we are asked regularly about Fenway Sports Group’s ownership in Liverpool.
"FSG has frequently received expressions of interest from third parties seeking to become shareholders in Liverpool. FSG has said before that under the right terms and conditions we would consider new shareholders if it was in the best interests of Liverpool as a club.
"FSG remains fully committed to the success of Liverpool, both on and off the pitch."
FSG purchased the club for £300m in 2010 and recent valuations from America business publication Forbes suggests the Reds are now worth around £3.6bn.
