Katherine Jackson to AEG -- YOU'RE CHARGING ME FOR PARKING!!!

Katherine Jackson is irate that AEG is asking her to pay more than $1.2 million in costs associated with the Michael Jackson wrongful death trial ... claiming many of the so-called "expenses" are bogus.

AEG -- which won the case -- is asking the judge to sock Katherine with court costs. But according to new docs, obtained by TMZ, Katherine is blanching at a bunch of them, including:

-- $540,000 in models and blow-up court exhibits
-- $20,000 for 1,000 pages of jury instruction paper and other stuff
-- $53,000 for process servers
-- $118,000 unnecessary depositions

Katherine is even grousing about the $9 parking fees tacked on for court reporters to show up for the trial.
