It's best that you clearly state in writing what you want done with your body following your death so that your family will know exactly what you want.
Embalming preseves the body for viewing by relatives and friends before and following the funeral.
Cremation can be immediate or following the funeral service and viewing.
Some people just want a memorial service without the remains being present. Some people just want to be cremated without any services. The choice is yours, of course. But there could be family conflict of what you want unless you've put it in writing.
One of my attorney friends wanted a social event (food and drinks) as his "memorial service." Attendees told great stories and we all laughed and cried.
The next blog will discuss the disposition of the cremated remains.
