The McCanns have made their daughter Madeleine a ward of court
The parents of Madeleine McCann will ask a High Court judge to order police files on the disappearance of their daughter to be released.
Leicestershire police have so far agreed with officers in Portugal not to disclose information on the case.
Kate and Gerry McCann hope the hearing on 7 July will give access to details of reported sightings of Madeleine.
Madeleine, of Rothley, Leicestershire, disappeared aged three in the resort of Praia da Luz, Portugal, on 3 May 2007.
'No stone unturned'
The McCanns have made Madeleine a ward of court, which allows a judge to act in the best interests of a child in a legal dispute.
The application to Mrs Justice Hogg is listed for the Family Division of the High Court.
The couple's spokesman Clarence Mitchell said: "An application has been made on Madeleine's behalf by her parents for the disclosure of certain documents.
"The case and the judgment may be in public and this will be a matter for the court to decide.
"It has been the stated intention of Gerry and Kate to leave no stone unturned in doing everything necessary in the search for their daughter, as would any other parent.
"This application is just part of their search for Madeleine."
A Leicestershire police spokeswoman said the force was aware that a court hearing was scheduled and it would be inappropriate to comment further.
