Incorporating a sole proprietor

K H

I am about to incorporate a long standing business for a number of reasons and transfer his assets , goodwill etc to the new Ltd company, that bit is straightforward.
However, I was intending for his wife to be a 50% shareholder.
As he is getting the benefit of the assets from the old business credited to him, and in light of the 'arctic systems' ruling can anyone see a problem here bearing in mind she is joining the new company from the outset and not being given shares in a long established company?

Thanks for your help.
