This is actually a probable scenario, knowing personal experience some years back.
I used to work in a garden centre, and one of the things we sold was those Mexican chimney things. A customer bought a terracotta one, and from what I can imagine, instead of seasoning it and starting off with a small fire, they lit a fire which was not warm enough, then stuffed loads in to make it hotter (all greenish wood). Not getting hot enough, they stuffed more in it, and then as the wood dried out, it took off and ended up like a volcano in the backyard, and the chimney just cracked up into several bits and collapsed.
Taking all the comments from everybody else here into account, I suspect you have a fairly good case.
How experienced is the person you sold the burner to in using properly seasoned wood?
Probably very inexperienced, and chucked on any old stuff around.
In fact, they probably even had a truckload of "seasoned" wood delivered in (we all know what "seasoned" wood means, had at least a month piled in a yard somewhere in a heap.....no chance of drying through.
Having a fire with unseasoned wood could easily cause a scenario like the Mexican chimney above, cracking cast iron if it's heated too quickly or stressed and heated in some areas more rapidly than others.
You can imagine it now, someone chucking more and more wood on to get instant heat like they are used to with an electric fire.
Think carefully through all the scenarios, without saying anything to the other person.
Prepare a whole set of questions about how they lit the fire, and how much they put on. How experienced are they in burning wood etc.......
If it was me, I would definitely go to court over it.
Just remember, once you make an offer, it will be seen as an admission of liability by anybody o the other side.
And as a last thought, when welding cast iron, you make a groove in the weld so it will take, just a different technique to welding steel.
That in itself does not make it incredibly expensive to do.
So I would be a bit suspicious of anybody who says how expensive it is to repair.
Plenty to think about there, so keep us posted as to how things go
