I've had a 50/50 claim. What option should I select when getting a quote?

For the question "Were you found to be at fault for the incident?", you should select "Yes".

Since both parties ended up sharing the costs in a 50/50 claim, technically it is a 'fault' claim for both too.

Don't worry, when you complete a quote, we always check our insurance databases to verify the details of any claims so the 50/50 element will still be noted.
