The analysis depends upon the intentions of the parties and surrounding facts.
If the intention is that shares are to be purchased for joint beneficial ownership by both parties then any capital gains and any dividends belong to each in proportion to the agreed split (eg 50/50).
However, if the shares are held in one name only the other person must be able to prove that they made a 50% (re above example) contribution to the purchase out of their own resources.
