In one sentenceSection 2033.420 lets a party who proves a fact or a document's genuineness at trial move for an order making the party who denied it pay the reasonable cost of that proof, including attorney's fees, unless the denial rested on a sustained objection, a waived response, an unimportant admission, a reasonable belief in prevailing, or other good reason.

(a) If a party fails to admit the genuineness of any document or the truth of any matter when requested to do so under this chapter, and if the party requesting that admission thereafter proves the genuineness of that document or the truth of that matter, the party requesting the admission may move the court for an order requiring the party to whom the request was directed to pay the reasonable expenses incurred in making that proof, including reasonable attorney's fees.
(b) The court shall make this order unless it finds any of the following:
(1) An objection to the request was sustained or a response to it was waived under Section 2033.290.
(2) The admission sought was of no substantial importance.
(3) The party failing to make the admission had reasonable ground to believe that that party would prevail on the matter.

Plain-English Summary

This section supplies the sanction that sets requests for admission apart from every other discovery method in the chapter: a cost-of-proof penalty for guessing wrong. If a party fails to admit the genuineness of a document or the truth of a matter when asked, and the requesting party later proves that document genuine or that matter true, the requesting party may move the court for an order requiring the party who would not admit it to pay the reasonable expenses incurred in making that proof, including reasonable attorney's fees. The threat behind this section is meant to discourage a party from denying something it has no real basis to dispute, forcing the other side to spend trial resources establishing what should have been conceded from the start.

The court has to grant that order unless one of several listed circumstances applies. No sanction follows if an objection to the request was sustained or a response to it was excused as a waiver, if the admission sought was of no substantial importance to the case, if the party who declined to admit had a reasonable ground to believe it would prevail on the matter at trial, or if some other good reason explains the failure to admit. Those exceptions give a party room to deny a request in good faith, based on a genuine and reasonable belief in its position, without exposing itself to fee-shifting for guessing wrong on a close call.
