control of a thing before forming the intention to possess it. If unknowingly sat on and therefore had control of a $10 note on the seat of a train, he or she could obtain possession by becoming aware of the note and forming the intention to possess it. People can also intend to possess things left, without their knowledge, in spaces they control. Possession can be obtained by a one-sided act by which factual control is established. This can take the form of apprehension (taking an object not in someone's possession) or seizure (taking an object in someone's possession).

A common transaction involving bailment is a conditional sale or hire-purchase, in which the seller lets the buyer have possession of the thing before it is paid for. The buyer pays the purchase price in installments and, when it is fully paid, ownership of the thing is transferred from seller to buyer.
