Section 123 in The Indian Contract Act, 1872
[Effect of use, by seller, of pretended biddings to raise price.] Rep. by s. 65, ibid.
Title: "Contract of indemnity" defined
A contract by which one party promises to save the other from loss caused to him by the contract of the promisor himself, or by the conduct of any other person, is called a "contract of indemnity".
A contracts to indemnify B against the consequences of any proceedings which C may take against B in respect of a certain sum of 200 rupees. This is a contract of indemnity.
Title: Rights of indemnity-holder when sued.
The promise in a contract of indemnity, acting within the scope of his authority, is entitled to recover from the promisor—
(1) all damages which he may be compelled to pay in any suit in respect of any matter to which the promise to indemnify applies;
(2) all costs which he may be compelled to pay in any such suit if, in bringing or defending it, he did not contravene the orders of the promisor, and acted as it would have been prudent for him to act in the absence of any contract of indemnity, or if the promisor authorized him to bring or defend the suit;
(3) all sums which he may have paid under the terms of any compromise of any such suit, if the compromise was not contrary to the orders of the promisor, and was one which it would have been prudent for the promisee to make in the absence of any contract of indemnity, or if the promisor authorized him to compromise the suit.
Title: "Contract of guarantee", "surety", "principal debtor" and "creditor".
A "contract of guarantee" is a contract to perform the promise, or discharge the liability, of a third person in case of his default. The person who gives the guarantee is called the "surety"; the person in respect of whose default the guarantee is given is called the "principal debtor", and the person to whom the guarantee is given is called the "creditor". A guarantee may be either oral or written.
Title: Consideration for guarantee.
Anything done, or any promise made, for the benefit of the principal debtor, may be a sufficient consideration to the surety for giving the guarantee.
(a) B requests A to sell and deliver to him goods on credit. A agrees to do so, provided C will guarantee the payment of the price of the goods. C promises to guarantee the payment in consideration of A's promise to deliver the goods. This is a sufficient consideration for C's promise.
(b) A sells and delivers goods to B. C afterwards requests A to forbear to sue B for the debt for a year, and promises that, if he does so, C will pay for them in default of payment by B. A agrees to forbear as requested. This is a sufficient consideration for C's promise.
(c) A sells and delivers goods to B. C afterwards, without consideration, agrees to pay for them in default of B. The agreement is void.
