For a contract to be legally binding, it must contain four essential elements: the contracting parties must exchange some value for the binding nature of a contract. This is called reflection. The reflection should not be reasonable or for the benefit of the other person, it must suffice (z.B. if someone offers to sell his house for nothing, there is no quid pro quo; but if they offer to sell it for $1, then there is a valid consideration). Or if you tell the printer that the offer seems excellent, except that the printer must use three colors instead of two, no contract has been concluded because you have not accepted all the important terms of the offer. They have actually changed a notion of supply. (Depending on your wording, you`ve probably made a counter-offer that will be explained below. For each valid contract, the following elements of the contract are essential: to validate a contract, any offer made must be accepted by the other party. This is usually a typical part of the contracting process. Counter-offers: A counter-offer denies the initial offer. It amends the initial offer and frees the person making the initial offer from any obligation. For example, A made an offer to deal with the sale of A Es Automobile for 10,000.00 $US.B offer A $9,000.00. If A accepts this offer, B is required to purchase the vehicle at that price.

A is not required to accept B`s offer and is not bound to it. Then made a counter-offer to B that A will sell the vehicle for $9,500.00. B is not obliged to purchase the vehicle at this price, but A is now required to sell the vehicle at that price to B if B accepts the counter-offer. Some contracts may indicate what should be paid in the event of an infringement. This is often called liquidated damage. –All parties agree (after one party has made an offer and accepted it by the other). If you tell the printer to keep working, you have accepted his offer. In the eyes of the law, if you tell the printer to go ahead, create a contract, which means that you are responsible on your side for the good deal (in this case, the payment of $200).
