How much information should I give my homeowners insurance when I file a claim?

Sorry to hear about the damage to your garage.  It is fairly normal for insurance companies to request these types of documents.  Often times they request cell phone records also (mainly if there is a fire investigation).   Insurance companies in general are just difficult to deal with.  While it is a pain, I'd consider providing them with the documents they request so they can conclude the investigation and hopefully pay your claim.  If they continue to delay the claim and request more documents that seem irrelevant, it may be time to seek assistance from a local lawyer in your state.  Best of luck!
