Spouse Visa, Saving route- £62500, joint account ok?

[themusicman1]

Hi all, I am about to renew my wife's spouse visa after 2.5 years. just want to ask for the 6 months saving of
£62500, can it be stored under a joint account with both our names? Or does it have to be under the name of the British citizen? Could it be under my wife's UK account?

Thanks for the help.
