Re: Opinion with respect to Three Year Notes of Southfield Energy Corporation planned to be issued pursuant to S-1 Registration Statement and Trust Indenture

Gentlemen:

By way of introduction, I am an attorney licensed to practice law in the State of Texas and in federal courts (in Texas and the United States Supreme Court) and am in good standing. I am a sole practitioner attorney, authorized to practice before the Securities and Exchange Commission and I have not been prohibited from practicing before the SEC or any other regulatory organization or any court. I am providing this opinion letter at the request of Southfield Energy Corporation (sometimes referred to hereinafter as “the Company,” or “the Registrant”).

I have acted as counsel for the Registrant, a Nevada corporation whose principal place of business is in Houston, Texas, with respect to assorted general and securities matters and specifically most recently in connection with the registration under the Securities Act of 1933, as amended, of notes designated as Three Year Notes to be issued pursuant to the S-1 Registration Statement and Trust Indenture to purchasers when the Registration Statement becomes effective. Such Three Year Notes (“the Three Year Notes”) described in the amended Registration Statement filed on the date hereof on Form S-1 with the Securities and Exchange Commission under the Securities Act of 1933, as amended (together with all amendments thereto) (the “Registration Statement”), proposed to be Registration Statement and Trust Indenture which constitute a Prospectus.

You have requested my opinion regarding the legality of the Three Year Notes registered pursuant to the Registration Statement. I have examined originals or copies, certified to my satisfaction, of such records, agreements and other instruments of the Company, certificates of public officials, certificates of the officers or other representatives of the Company, and other documents, as deemed necessary as a basis for the opinions hereinafter set forth. As to various questions of fact material to such opinions, I have, when relevant facts were not independently established, relied upon written factual representations of officers and directors, including (but not limited to) statements contained in the Registration Statement.

I am familiar with applicable Nevada and Texas law and the Securities Act of 1933 and applicable SEC Rules. I have reviewed again, in preparing this opinion, pertinent provisions of the Securities Act of 1933 and the Trust Indenture Act of 1939. My opinion is confined to Texas, Nevada, and United States law.

I have assumed the genuineness of all signatures on documents reviewed by or presented to me, the legal capacity of natural persons, the authenticity of all items submitted to me as originals and the conformity with originals of all items submitted as copies.
