The decision of whether your loved one's funeral will be a burial or cremation needs to be taken first. The person themselves may have expressed their wishes, or there may be religious beliefs that govern this decision.
If burial, then unless there is a family burial plot available, you need to decide which cemetery to use.
If a cremation is to take place, you can decide which crematorium to use.
You may have a preference for the day, date and timing of the funeral and this may affect your decision of location.
