Tex. Ins. Code § 707.004

An insurer that issues a property insurance policy with replacement cost coverage may refuse to pay a claim for withheld recoverable depreciation or a replacement cost holdback under the policy until the insurer receives reasonable proof of payment by the policyholder of any deductible applicable to the claim. Reasonable proof of payment includes a canceled check, money order receipt, credit card statement, or copy of an executed installment plan contract or other financing arrangement that requires full payment of the deductible over time.
