Andrew Mountbatten-Windsor is taking legal action against Thames Valley Police over search warrants issued before his arrest in February.
The former Prince Andrew was arrested on suspicion of misconduct in public office, in the wake of information that emerged from the Epstein files in the US.
Mountbatten-Windsor has consistently denied any wrongdoing linked to his association with Epstein.
The warrants had been issued by a judge one day before the former prince was arrested.
His lawyers are challenging the lawfulness of the search warrants.
A court hearing will be held on Thursday, with the matter set to begin in private.
