Sources connected with Oksana tell us ... Mel must pay the $300k immediately ... per Judge Scott Gordon.

TMZ has been privy to a partial tab on how much Oksana's lawyers -- which total more than 40 -- have asked requested. That figure exceeds an incredible $3 million. Mind you ... it's a custody case involving one kid.

We don't have a tally of how much was actually rewarded, but it well exceeds $1 million, and counting.

Justice -- it ain't cheap.
