Tex. Finance Code § 187.105

(a) A trust office of an out-of-state trust company may be acquired or established in this state under this subchapter if:

(1) the out-of-state trust company confirms in writing to the banking commissioner that while it maintains a trust office in this state, it will comply with all applicable laws of this state;

(2) the out-of-state trust company provides satisfactory evidence to the banking commissioner of compliance with Section 201.102 and the applicable requirements of its home state regulator for acquiring or establishing and maintaining the office;

(3) all filing fees have been paid as required by law; and

(4) the banking commissioner finds that:

(A) applicable conditions of Section 187.102 or 187.103 have been met;

(B) if a state bank is being acquired, the applicable requirements of Subchapter A, Chapter 33 have been met, or if a state trust company is being acquired, the applicable requirements of Subchapter A, Chapter 183 have been met; and

(C) any conditions imposed by the banking commissioner pursuant to Subsection (b) have been satisfied.

(b) The banking commissioner may condition approval of a trust office on compliance by the out-of-state trust company with any requirement applicable to formation of a state trust company pursuant to Sections 182.003(b) and 182.007.

(c) If all requirements of Subsection (a) have been met, the out-of-state trust company may commence business at the trust office on the 61st day after the date the banking commissioner notifies the company that the notice required by Section 187.104 has been accepted for filing, unless the banking commissioner specifies an earlier or later date.

(d) The 60-day period of review may be extended by the banking commissioner on a determination that the written notice raises issues that require additional information or additional time for analysis. If the period of review is extended, the out-of-state trust company may establish the office only on prior written approval by the banking commissioner.

(e) If all requirements of Subsection (a) have been met, the banking commissioner may otherwise deny approval of the office if the banking commissioner finds that the out-of-state trust company lacks sufficient financial resources to undertake the proposed expansion without adversely affecting its safety or soundness or that the proposed office is contrary to the public interest. In acting on the notice, the banking commissioner shall consider the views of the appropriate supervisory agencies.
