This sounds like stuff I've read about countries that are predominantly Orthodox Christian (Greece, Russia, etc.) The various Orthodox Churches are pretty hardcore about suicide being a bigtime sin. FWIW, my theory is that is why the reported suicide rate is so much lower in a place like Greece than in most of the rest of Europe. The families want the deceased to have an Orthodox funeral and if the death is declared a suicide they can't get it. Meaning the priests, doctors, etc., go out of their way to call the death anything BUT a suicide. And something like 95% of the population of Greece is at least nominally Greek Orthodox Christian.
I think it varies by denomination in the USA, and in a lot of places, at least in the northeast, the cemeteries are actually run by the towns. Meaning no religious affiliation needed to buy a plot. Just the $$ to do so.
I don't think most
Protestant denominations, from the most conservative to the most liberal, have any particular sense that there's "hallowed" ground when it comes to churches or cemeteries. Meaning they're fine with the deceased who committed suicide being buried inside a cemetery. Whether they would allow a service to be held in their church, dunno, I guess that would vary by denomination. I think some consider suicide a sin, some are more forgiving. But I can't see any nonsense about being buried inside or outside of certain properties.
If your family wants you to be buried as a
Catholic and you commit suicide there very well could be issues for a family seeking a Catholic burial. It IS considered a sin, and potentially a grave one, on par with murder. However, I think nowadays most priests let it go, using the "grave psychological disturbances" excuse from the
Catechism of the Catholic Church. (

My reading of the above, and from what I've been told, inclines me to think if you or your family wants a Catholic burial it is available, including burial in hallowed ground. I guess you just couldn't be a celebrity with a large following among the young or some such thing (see paragraph 2282 above).
Kind of the "Well, no, but actually yes" attitude the Church has about topics like divorce, I guess. On paper suicide is a very bad thing. In practice, not so much. Or so I've come to think.
Most Jews in America are Reform Jews, meaning their religious practice is cultural more than it is anything else, at least to my cynical eye. I doubt a suicide would have any trouble being buried in a Jewish cemetery, at least of the Reform branch. (Conservative, Hasidic, etc., dunno. Maybe not.)
No clue what Mormons do about suicides. Not many around where l live. (Personally don't consider Mormons to be Christians. Too many differences. Nice enough people, just not Christian.) I guess since they do after-death baptisms and other weirdness they have no problem with suicides getting buried via their Temple ceremonies.
Good grief. Sorry for wasting everyone's time with this wall of text.
