Medieval Latin affīdāvit, from third person sing. past tense of Latin affīdāre, to pledge; see affiance.(American Heritage® Dictionary of the English Language, Fourth Edition)
From Medieval Latin affidavit ("he has sworn"), the third person singular perfect tense of affido ("swear"), from fīdō, ultimately from Proto-Indo-European *bʰidʰ-, zero-grade of Proto-Indo-European *bʰeydʰ- (“to command, to persuade, to trust”). Cognate to fidelity and faith (same Latin root), but not to affirm (shared Latin ad- prefix, but different Latin and Proto-Indo-European roots). (Wiktionary)
