I think Chara's soul would most likely shattered as a normal human and monster soul does after he died alongside Asriel when they're plan failed. Through means not entirely clear in the game, Chara's essence somehow made its way into Frisk though this may be because Frisk landed around the place Chara was buried.

I think Toriel took Chara's corpse and reburied it when she left Asgore hence explaining the empty coffin with Chara's name on it.
