A third and final preliminary hearing ahead of fresh inquests into the deaths of 96 Liverpool fans killed in the 1989 Hillsborough disaster will be held in London on October 7.
The pre-inquest hearing, chaired by coroner Lord Justice John Goldring, is expected to clarify exactly where the inquests will be held.
Lord Justice Goldring announced at a first hearing in April that the inquests would be held in the North West of England, closer to Liverpool, rather than in London - although an exact venue was not specified.
At a second pre-inquest hearing, in June, he confirmed that the new inquests would begin on March 31, 2014.
Families had hoped to learn over the summer where in the North West the inquests would be held. But they now believe they will have to wait until the October hearing, at which Lord Justice Goldring will also set out a timetable for the inquests.
Margaret Aspinall - chair of the Hillsborough Family Support Group, which campaigns of behalf of the disaster victims and their families - told the Liverpool Echo: "We think we will probably have to wait until then.
"It is quite frustrating as we had hoped it would be sorted out by now, but as long as it goes ahead we will be satisfied.
"We expect this will be the last one before the full inquests themselves get under way.
"There will be a lot of significant new information to take in and directions made by the coroner."
Ninety-six supporters were crushed to death at the FA Cup semi-final between Liverpool and Nottingham Forest at Hillsborough, home of Sheffield Wednesday, on April 15, 1989.
The original inquests, conducted by Dr Stefan Popper, returned verdicts of accidental death in March 1991.
Campaigners have maintained that those verdicts, and the manner in which the inquests were conducted, prevented a proper investigation into the role of the police and emergency services on the day of the tragedy.
An independent report, published last September, cleared fans of any blame for the disaster and highlighted the extent to which the police and emergency services had attempted to cover up their own culpability.
The original inquest verdicts were quashed in December, two months after the Independent Police Complaints Commission (IPCC), the UK's police watchdog, announced that it would carry out a two-year investigation into both the role played by officers on the day and the subsequent cover-up.
A second investigation, focusing on possible criminal behaviour by any people or bodies with responsibility for fan safety at Hillsborough, was set up in December and is being headed up by former Durham chief constable Jon Stoddart.
