My only other thought would be possibly contacting the local police department and asking them (laying out your concern for the fire and the need to have some sort of documentation that he is indeed yours) what they would consider legal proof that he is your horse other than those things you mentioned you don't have.
This sounds like a good idea. I've been puzzling over my draft cross...she's just a plain sorrel, so how do you explain to police or who ever the difference between one sorrel horse and the next?!
I figured microchipping might help, (though who would think to check?) but I guess asking a law enforcement agency what *they* would look for is a good bet!
