POWER OF ATTORNEY


	KNOW ALL BY THESE PRESENTS, that the undersigned hereby constitutes and
appoints Loral R. Conrad, Drew F. Nachowiak, James R. Peacock III, and Brian J.
Woram, and each of them, with full power to act alone, as his/her true and
lawful attorneys-in-fact and agents, for him/her and in his/her name, place and
stead, in any and all capacities, to (1) prepare, execute and acknowledge any
and all forms of report with respect to the undersigned's beneficial ownership
(and changes in ownership) of securities of Centex Corporation, a Nevada
corporation ("Centex"), required under Section 16(a) of the Securities Exchange
Act of 1934, and Section 5 of the Securities Act of 1933, and the rules and
regulations thereunder (individually and collectively, the "Acts"), including,
but not limited to, a Form ID, Forms 3, 4, 5, and 144, and any amendments
thereto, and (2) deliver or file or cause to be delivered or filed such
documents, and any other documents in connection therewith, with the Securities
and Exchange Commission, any applicable stock exchange, and Centex, granting
unto each of the said attorneys-in-fact and agents full power and authority to
do and perform each and every act and thing requisite and necessary to be done,
as fully for all intents and purposes are he/she might or could do in person.
The undersigned hereby ratifies and confirms all that said attorneys-in-fact and
agents, or any of them, may lawfully do or cause to be done by virtue hereof.

	The undersigned agrees that each of the attorneys-in-fact herein may rely
entirely on information furnished orally or in writing by the undersigned, or at
the direction of the undersigned, to such attorney-in-fact.  The undersigned
hereby acknowledges that the foregoing attorneys-in-fact, in serving in such
capacity at the request of the undersigned, are not assuming, nor is Centex
assuming, any responsibility or liability of the undersigned to comply with the
Acts or any such requirements, nor does it relieve the undersigned from his/her
obligation to comply with such requirements.

	This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file the documents described in the first
paragraph hereof, unless earlier revoked by the undersigned in a signed writing
delivered to the foregoing attorneys-in-fact or superseded by a new power of
attorney regarding the purposes outlined in the first paragraph hereof dated as
of a later date.  Effective as of the date of this Power of Attorney, the
undersigned hereby revokes any and all earlier-dated powers of attorney given by
the undersigned for the purposes outlined in the first paragraph hereof.

	The validity of this Power of Attorney shall not be affected in any manner by
reason of the execution, at any time, of other powers of attorney by the
undersigned in favor of persons other than those named herein.

	IN WITNESS WHEREOF, I have hereunto set my hand this 10th day of October, 2007.
