I have no family and I have a friend that I want to write a living will to so when I do pass I couldn't be cremated.

A living will is for when you are alive.

if you are concerned about funeral arrangements, then you should prepay and preplan your funeral.

This information should available easily in your home, a copy could be included with your Will, but it should also be easily accessible without your Will.

Contact an elder law attorney. Is friend willing to make the end of life decisions?

A living will is about care you want or don't want when there is a medical issue.
