In the UK the seller is the owner of the house together with any mortgage lender, the proportion of ownership depends on the amount outstanding on the mortgage. If the seller dies then the 'estate' will own the sellers proportion of the house. The estate will pass on to the next of kin or anyone nominated in the sellers will.

Transaction happens when supply and demand meet. Both sides (a seller and a buyer) meet their needs: a seller gets money for its products (now he can manufacture next products) and a buyer gets product he needed.
