Barrymore is facing a private prosecution relating to events surrounding the death of Lubbock, who drowned in the entertainer's swimming pool in 2001.
At Epping Magistrates Court yesterday, district judge John Greaves granted private lawyer Tony Bennett permission to bring a private prosecution against Barrymore, who is holed up in the 'Big Brother' house after returning to the UK from New Zealand.
Bennett travelled to Elstree studios on Monday with Lubbock's parents to hand the papers to Barrymore in person after the judge ruled Barrymore must be notified about the proceedings.
However, 'Big Brother' producers refused them entry and would not hand the papers to Barrymore and instead said the papers must be handed to Barrymore's lawyers.
The six charges being brought against the star relate to drink and drugs crimes at the party. In particular, he has been accused of being drunk and disorderly, possession of a class B drug, supply of a class B drug, possession of a class A drug, supply of a class A drug and assaulting Stuart Lubbock.
Lubbock was found later that evening drowned in the star's pool after suffering "horrific" sexual injuries.
Barrymore has always skirted around certain issues such as the use of drugs at the party where the death happened.
An inquest into Lubbock's death returned an open verdict, but his family have long blamed Barrymore. Lubbock's father has already criticised Channel 4 for being "ghoulish" in allowing Barrymore to take part in this year's series.
Meanwhile back in the house, former NBA basketball player Dennis Rodman, former FA secretary Faria Alam and the cross-dressing Dead or Alive lead singer Pete Burns are up for eviction on Wednesday, after receiving the most votes from fellow housemates.
