Autocorrected name on insurance policy

My partner's name autocorrected to 'Domestic' when signing up and he didn't notice. Recently he's been involved in a crash (police response going through red, he wasnt at fault) and only realised he's now called Domestic when his insurance company called him. He's changed his name online, but he's worried this means his insurance was void at the time of the crash and he's spiralling i.e. police won't accept liability (though surely body cams, cctv, black box etc) and his insurance isn't valid, he'll get points, get fined, or lose license. He's like this cos he's been screwed so many times.

To me, I'm thinking it's just an autocorrect and no one will be so harsh. But I also know how awful companies can be. What's the reality of the situation here, can I reassure him?

Also I do intend to mock him and call him Domestic, as soon as he's no longer under stress
