The trial is scheduled to take place in January.
Aged 62, the British actor accuses the Sun, whose publisher NGN denies any illegal process, of having used private detectives.
Judge Timothy Fancourt ruled that Hugh Grant's lawsuits should be examined at trial, with the exception of some of them, relating to phone hacking. The magistrate considered that the actor should have initiated the prosecution earlier in this regard.
A similar procedure has been initiated by Prince Harry. A decision on whether to hold a trial will be known in the coming months.
In his conclusions, Hugh Grant accuses the Sun of "illegal acts" including "commissioned burglary, trespassing on private property to obtain information by placing microphones, tapping landline telephones", as well as "telephone hacking and the use of private investigators to accomplish the whole".
A spokesman for NGN welcomed the dismissal of the charges of phone hacking, saying the group "strongly denies the accusations of illegal information gathering contained in what remains of the proceedings initiated by Mr. Grant".
Welcoming the judge's decision, Hugh Grant said it was "necessary for the truth to come out" about the Sun's activities, stressing that this case "goes much further than interceptions of voicemail".
