What is the timely manner for filing insurance claims in Texas?

It is always a good idea to file insurance claims as soon as possible. There is no good reason to delay (although if you are hospitalized, you might need help filing the claim). Delays of a month would not be unusual. People have lots of things on their minds, and it could take that long to get around to the matter of insurance claims. Longer delays than that would seem excessive although not necessarily so excessive as to cause the insurance company to reject the claim. If you let it go for a year, however, that is too long.
