In my country, Mexico, the law doesn't recognize euthanasia, just suicide/homicide. Suicide of course is not a crime, because what are they going to do, jail you? Assisting suicide in any way is murder, though.
There are still repercussions for the people you leave behind. I can recall these:
- Any insurance is void
- Inheritance can be complicated if you can argue that the suicide was encouraged. It becomes premeditated murder.
- I think debt, specially if it's considerable, is handled different that natural death, that voids any debt.
