Background

Stephane Siantou obtained a home mortgage from North American Savings Bank in January 2022. His homeowners’ insurance premiums were prepaid for 12 months at closing. NASB sold the loan to JPMorgan Chase Bank in March 2022 and notified both Siantou and his insurer of the servicing transfer.

After the transfer, Siantou’s insurer initially canceled his policy because of a preexisting open water claim and refunded excess premiums to him. The policy was reinstated without a lapse, but a new premium became due and went unpaid, leading to another cancellation and a collections referral. Siantou, who was traveling overseas, said he did not receive the insurer’s notices and learned of a possible credit problem after two requests for credit-line increases were denied.

Siantou sued NASB for promissory estoppel, breach of contract, violations of the Texas Deceptive Trade Practices Act, negligence, negligence per se, and gross negligence. He alleged that NASB failed to pay his insurance premiums or arrange for continued escrow disbursements.

The Court’s Holding

The court granted NASB summary judgment on every claim and dismissed the case with prejudice. Promissory estoppel was unavailable because the parties’ rights were governed by the valid Note and Deed of Trust. The breach-of-contract claim also failed because the Closing Disclosure was not itself a contract, Siantou identified no breached provision of the Note or Deed of Trust, and the evidence showed that the first year’s insurance premium had been paid before NASB transferred the loan.

The court additionally found insufficient evidence connecting NASB to Siantou’s claimed damages. The credit-denial notices did not identify the insurance account or NASB as the cause, and Siantou admitted that another account was in collections during the same period. His generalized allegations and unsupported testimony did not establish additional damages.

The DTPA claim failed because Siantou was not a consumer for the challenged transaction: his objective was obtaining a mortgage to purchase a home, while insurance-related servicing was incidental to the loan. His negligence theories failed because the lender-borrower relationship imposed no duty of care supporting negligence, negligence per se, or gross negligence. The court rejected NASB’s Article III standing argument, overruled Siantou’s objections, and denied the remaining motions as moot.

Key Takeaways

  • A borrower cannot use promissory estoppel to bypass a valid written loan agreement governing the parties’ rights and obligations.
  • A Closing Disclosure describing loan terms and costs is not independently enforceable as a contract when it directs the borrower to the Note and Deed of Trust.
  • Claims based on mortgage servicing require competent evidence of breach, causation, and damages; ambiguous credit denials and unsupported testimony were insufficient here.
  • Incidental loan-servicing activities did not make the borrower a DTPA consumer, and the lender-borrower relationship did not create a negligence duty.

Why It Matters

The decision illustrates the evidentiary and doctrinal barriers facing borrowers who attribute insurance or credit problems to a former mortgage lender. A plaintiff must identify an enforceable contractual obligation, show that the defendant breached it, and connect that breach to provable damages.

It also reinforces that Texas promissory-estoppel, DTPA, and negligence theories generally cannot substitute for a deficient contract claim when the dispute concerns obligations governed by loan documents and services incidental to a mortgage.
