If you control Sigarda, Host of Herons and your opponent enchants one of your other creatures with Soul Tithe (obviously they can’t cast Soul Tithe targeting your Sigarda thanks to hexproof), then when Soul Tithe’s ability resolves it will ask, “Wanna pay this thing’s converted mana cost?” At that point, you can pay if you really want to, but when you don’t, it will say, “Ok, sacrifice this thing then!”

However, Soul Tithe’s triggered ability is controlled by the opponent who cast and still controls Soul Tithe (even though it’s attached to your creature), so Sigarda says, “Nope. There will be no sacrifices here.”

So I recommend not paying the Tithe, and just carrying on normally. 🙂
