Similarly, my job lets me claim a part of the monthly internet bill as a work-from-home expense, but my ISP cost me 6 months expenses because they couldn't transfer the account to my name from my SO's. Same last name, same address. To start a new account they wanted a sign up fee equal to about 3 months of said expenses. Employer would not accept a copy of the bill in my SO's name (same surname, same address) citing tax fraud, which surely would have been our own breach of law if we both had been making the same claim on the same bill.

Bureaucracy won again. Until we got a different operator at the ISP who worked out that they could add my name as if the account was landlord & renter scenario, so there could be an owner and another who was responsible for payment.
