Why This Document Matters
The affidavit exists so that a funding promise carries legal weight rather than social weight. A letter says somebody intends to pay; a sworn affidavit says they have declared it before a notary, with a register entry that can be traced. That is why missions asking for one will not accept a letter in its place — and equally why paying to swear an affidavit for a mission that never asked for one adds cost and nothing else.
