How soon can we plan for services?

Planning for a funeral---Once the deceased has been removed from where ever they have died, I will meet with the family when it is convenient for them.I will need to get general information about  the deceased to be able to generate the death certificate This death certificate has to be signed with the cause of death by the Dr. or Coroner then it must go to the registrars office to be signed, it will take several days for this to happen,  Cremation or burial cannot be done until this procedure has taken place. Please do not make any flight plans for family or set any times for services with your church or organization, as sometimes it does not work out.
