Here is another Federal opinion discussing Texas Insurance Code, Section 542A. The opinion is from the Eastern District of Texas and is styled, John McAdams v. Palomar Specialty Insurance Company, Wellington Claim Service, Inc. and Nicholas Abdallah.
McAdams had a homeowners insurance policy with Palomar when he suffered damages alleged to have been caused by Hurricane Harvey. Palomar assigned Wellington to investigate the claim and Wellington assigned adjuster Nicholas to inspect the claim.
The claim was not sufficiently covered according to McAdams and he eventually filed suit against Palomar, an out of state defendant, and against Wellington and Nicholas, both in-state defendants. McAdams alleged wrongs committed in the claims handling process.
