The inquest into the death of former Welsh government minister Carl Sargeant is due to open on Monday.
Mr Sargeant, 49, is understood to have taken his own life on Tuesday, four days after being removed from his role as cabinet secretary for communities and children.
He was suspended from the Labour Party over allegations of "unwanted attention, inappropriate touching or groping".
The hearing at the Coroner's Court in Ruthin is expected to be opened and adjourned at 1pm on Monday.
Welsh First Minister Carwyn Jones has called for a senior QC to carry out an independent inquiry to examine his handling of the case.
Mr Sargeant's family has criticised the decision to ask the Permanent Secretary to begin preparatory work and said it will prevent the probe from being truly independent.
