Re:      Registration Statement on Form S-8


Ladies and Gentlemen:

     We have acted as special counsel to First Advantage Corporation, a Delaware
corporation (the "Company"), and are familiar with the proceedings and documents
relating to the proposed registration by First Advantage, through a Registration
Statement  on Form  S-8  (the  "Registration  Statement"),  to be filed by First
Advantage with the Securities and Exchange Commission, of (a) up to an aggregate
total of 788,232  shares of First  Advantage's  Class A Common Stock,  $.001 par
value (the "Stock"),  issuable under the following  plans of US SEARCH.com  Inc.
(the "Plans"):  (i) 1998 Amended and Restated Stock Option Plan, as amended (ii)
1999 Non-Employee Directors' Stock Option Plan, as amended, and (iii) 2000 Stock
Incentive Plan, as amended.

     For the purposes of rendering this opinion,  we have examined  originals or
photostatic copies of the Plans and such corporate records, agreements and other
documents of First Advantage as we have deemed relevant and necessary as a basis
for the opinion  hereinafter  set forth.  In connection  with our examination of
such  documents,  we have assumed the  genuineness of all signatures on, and the
authenticity  of, all documents  submitted to us as originals and the conformity
to the original  documents  of all  documents  submitted  to us as copies.  With
respect to instruments  executed by natural  persons,  we have assumed the legal
competency  and authority of such persons.  As to facts material to the opinions
expressed herein which were not independently  established or verified,  we have
relied upon oral or written statements and representations of First Advantage.

     Based on the foregoing,  in reliance thereon and subject to compliance with
applicable  state  securities laws and the assumptions  and  qualifications  set
forth herein, we are of the opinion that the Stock, when issued and delivered in
accordance  with  the  terms  and  conditions  set  forth  in  the  Registration
Statement,  the Plans and any related documents,  will be validly issued,  fully
paid and nonassessable.

     We  hereby  consent  to the  use  of  this  opinion  as an  exhibit  to the
Registration  Statement.  In giving such consent, we do not thereby concede that
we are within the category of persons whose consent is required  under Section 7
of the Securities Act or the Rules and Regulations of the SEC  thereunder.  This
opinion is furnished by us, as special  counsel to the  Company,  in  accordance
with the  requirements  of Item 601(b)(5) of Regulation S-K under the Securities
Act and, except as provided in the immediately  preceding sentence, is not to be
used,  circulated  or quoted for any other  purpose or otherwise  referred to or
relied upon by any other person  without the express  written  permission of the
undersigned.


                                                     Very truly yours,


                                                     /s/ White & Case LLP
