Example: A contracts to buy a car from B by paying cash, B instantly delivers his car.
(b) Executory contract:- A contract in which both the parties have still to fulfilled their

Example : D agrees to buy V’s cycle by promising to pay cash on 15th July. V agrees to
deliver the cycle on 20th July.
(c) Partly executed and partly executory:- A contract in which one of the parties has
fulfilled his obligation but the other party is yet to fulfill his obligation.
Example : A sells his car to B and A has delivered the car but B is yet to pay the price.
For A, it is excuted contract whereas it is executory contract on the part of B since the
price is yet to be paid.
On the basis of liability for performance:-
(a)Bilateral contract:- A contract in which both the parties commit to perform their
respective promises is called a bilateral contract.
Example : A offers to sell his fiat car to B for Rs.1,00,000 on acceptance of A’s offer by
B, there is a promise by A to Sell the car and there is a promise by B to purchase the car
there are two promise.
(b)Unilateral contract:- A unilateral contract is a one sided contract in which only one
party has to perform his promise or obligation party has to perform his promise or
obligation to do or forbear.
Example :- A wants to get his room painted. He offers Rs.500 to B for this purpose B says to A
“ if I have spare time on next Sunday I will paint your room”. There is a promise by A to pay Rs
500 to B. If B is able to spare time to paint A’s room. However there is no promise by B to Paint
the house. There is only one promise.
Therefore hence they both are not Same....
