Deion Sanders Appeals Five Figure Monthly Support Order

Sanders just filed docs in Texas Supreme Court challenging the support order that was established in a lower court back in May.

In his docs, Sanders says $10k/month is actually SIX TIMES more than Texas law requires ... and he wants his child support obligation significantly reduced.

But Pilar claims Deion is worth roughly $250 MILLION ... and the TX Supreme Court shouldn't have any sympathy for Prime Time ... or change the support structure that's already in place.

In fact, Pilar has filed her own legal docs outlining why she needs so much cash from Deion. Among the highlights:
-- $2,000/month for a special diet for the kids
-- $900/month on uniforms and shoes for the kids' sports activities
-- $500/ month on the children's cell phones

Pilar also claims she spends $450 on haircuts for her sons and treatments for her daughter's "very thick curly hair."

Pilar's lawyer tells TMZ, "Once again, Mr. Sanders has not followed the Court's direct orders and has attempted to make up his own rules. It is clear that he still thinks he is "above the law."
