Tex. Ins. Code § 911.155

The company's bylaws may authorize the company to require, at its option, that all or a percentage of the money paid for a loss be used to replace or repair the damaged or destroyed property. The requirement may apply equally to personal and real property, including personal and real property exempt from execution, such as a homestead or a building on the homestead. The company may provide in its bylaws that the requirements of Section 862.053 do not apply to its insurance policies.
