Establishing fair value in a one man band company

I imagine you saying this, then downing your drink and ordering another one without hesitation as you continue talking about why radiators need bleeding lol

You joke but the fastest way to loose friends and family is when money is involved. His brother has had a free income for zero work no one here knows how that conversation is going to go down.

Gifting shares to a non-fee earner, who isn’t a spouse is a problem.
As this is a share transfer the other way I can’t see any reason why £1 per share would ever be questioned by HMRC.
I there is a risk it’s more about if HMRC want to see the tax the OPs brother was paying, and whether they’d consider that a settlement.
