Apart from the practical considerations, one of the reasons we hold a funeral reasonably soon after someone’s death is that it provides a touchstone for our mourning. It is a kind of milestone that helps us to make sense of the shift in our relationship with that person.
However, there are many reasons you might want to delay a funeral. For example, if the death was sudden and you need time to plan; or if you are waiting to get in contact with friends or family who are travelling or difficult to contact. One option is to have the burial or cremation in the short term and then hold a memorial service at a later time when you are feeling stronger or more prepared.
