Claiming for mileage incurred by business partnership

My wife and I are considering registering a business partnership. In order to claim the 45p per mile allowance, would the partnership need to be the registered owner of the vehicle? Or would it be acceptable for the registered owner to be one of the partners? In this scenario, the registered owner (my wife) would be the only person ever to use the vehicle for business purposes as I don't drive.

Hi ,
 

This is acceptable as long as none of the partners are a company . Thank you .
