The best answer is given by Spoke:

> The use of parenthetical numbers is an historical holdover from the days when legal documents were written out by hand. Of course , not everyone has the greatest handwriting in the world, so it became customary to both write out the number, and to use arabic numerals, to lessen the chance that a particular number might be read incorrectly. (This was particularly important in deeds, where the measure of one’s real estate holdings were set out with verbal descriptions. Reading the footage incorrectly could cause some real problems–overlapping property lines, angry neighbors, misplaced spite fences, etc.)

Personally, I don’t find it annoying and actually like the accuracy for the same reason you write out the numbers alphabetically on a check then numerically. Accuracy. If there’s a large discrepancy and/or the numeric section isn’t filled out on large amouints, the check may be rejected. If the discrepancy or cash amount is small, the written out amount will be likely be used and accepted.
