CGT on share dealing, sole account, split evenly with partner on self assessment

Not sure if this is best in this forum or the self assessment forum. We are a married couple. We have had a share trading account in my name but use this account to trade for both of us. We split the annual profit or loss on each of our self assessments 50/50 on the basis that all our assets are held in common. We have always done this and it has always been a 50/50 split including dividends. Profits are transferred to a joint bank account. Is this ok? I know that we could set up a joint trading account. Thank you.

Just bumping this back up the list because I think the post was delayed from being public until it had been moderated. Any answers? Thank you!
