Will there be a private place to wait? 
It depends on the facilities at the coroner’s court, which can vary enormously. There is not always a private place for families and friends to wait or talk with legal representatives. Some may have waiting rooms and some coroners may consider making one available for families and their lawyers. Ask the coroner’s office if you would like this to happen, or ask your solicitor to do it for you.
What should I bring to an inquest?
There’s nothing you need to bring with you. However, lots of families like to bring a photograph of their loved one to the inquest, and sometimes the coroner will allow you to show the photograph to the jury. 
What should I wear?
You should wear clothes you feel comfortable in. The coroner, lawyers and witnesses will be dressed formally, but this is not a requirement for you.
Who has the right to attend?
Anyone. An inquest is a public hearing. You may want to bring friends or family along with you for support. Some coroner’s courts are small and this limits the number of people who are able to attend. 
How long will it take?
This can vary significantly depending on the individual circumstances and the coroner’s approach. Many inquests last just a few hours, whilst more complicated deaths can take days or even weeks.
Will the press and public be there?
Because an inquest is public, the press may attend and report on what’s happening. You cannot stop them from writing about the hearing, but they do have to follow a code of ethics and should be sensitive to grieving families.
