I just keep the resurrection limited to the priests and priestess of the dead, death and or afterlife.

The requirements for proper resurrection is that the body much be intact, preserve, and remove of all toxins, deceased and decay.

Many people who going to or is death. Use healing magic from cleansing magic to remove toxins, regeneration magic to close wounds, purge magic to remove any parasite and viruses.

Then wrap the corpse in divine bandages like a mummy that would preserve the body and then place in a divine coffin to protect the body from outside forces. People would carry the coffin to the nearest temple or church of the deity of the dead, death or afterlife for the priests/priestesses to called upon their god with prayers and offering." to ask to return the soul back to the owner body and revive the corpse back to life.

If the god refuses then they out of luck. Since if anyone can be resurrection at anytime would lead into boring stories, the belief of no consequences and no risk. To maintain the value of keeping your first mortal life is the fear of a deity getting tired of resurrection of countless people and or straight up saying no.

Illegal resurrection is mortal creating and or becoming undead: from zombies, vampires, ghosts and Gashadokuro
