As is acknowledged in the following case, the federal courts are mixed as to their rulings on the timing of when an insurance company adjuster is sued and how that affects diversity cases.
This case is from the Western District of Texas, San Antonio Division. It is styled, Bexar Diversified MF-1, LLC v. General Star Indemnity Company, Paul R. White And Company Inc.
Bexar had an insurance policy with General Star. Bexar suffered a weather related loss and reported it to General Star. General Star assigned White, a company, to adjust the claim. Bexar was dissatisfied with the way the claim was handled and sued General Star and White in state court for violations of the Texas Insurance Code, Sections 541 and 542.
