You're absolutely right. Usually, we're talking about legal and not moral obligations.
For just that reason, I won't lend money to home purchasers or people who want to refinance without requiring more than just signatures on notes, deeds of trust or mortgages. I insist that borrowers also sign a Covenant With God and pledge their Immortal Soul as part of the deal. If the borrower balks, then he's going home without any money. I have no sympathy for the banks or lenders who made their loans without the proper Covenant.
lol...ah, the old Immortal Soul clause. Pretty iron-clad, I’m told.
Does God show up to the closing himself to sign? Does an angel come with power of attorney?
