Gifted shares sold but settlement account is in joint names

I gifted some shares to my husband. The settlement account for his broker is our joint current account. Once sold and funds received he will be moving them to a sole account with another bank. His gain is under the annual £6k allowance. Is this ok? Or does he have to open a settlement account in his sole name? So we can avoid the CGT? Hmrc website isn’t very clear

Hi Gillian Brown,
As long as the actual shares are in his name, it will be seen as his gain for tax purposes.
Thank you.
