Statutory text
Bare law
The liability of the surety is co- extensive with that of the principal debtor, unless it is otherwise provided by the contract.
Illustration
A guarantees to B the payment of a bill of exchange by C, the acceptor. The bill is dishonoured by C. A is liable, not only for the amount of the bill, but also for any interest and charges which may have become due on it.
Rule and business relevance
Read the guaranteed obligation together with the guarantee’s cap, exclusions and other terms. The statutory bill illustration includes interest and charges that have become due as well as principal.
Limits and related provisions
Co-extensive liability is not a rule that every guarantee is unlimited. Nor does this short provision resolve every procedural, limitation or insolvency issue affecting enforcement.
Hypothetical business example
Hypothetical example: A guarantee expressly caps exposure at a stated sum. The creditor must consider that contractual limit rather than assuming every component of the debtor’s larger liability is recoverable from the surety.
Practical decision flow
Establish the principal debtor’s enforceable obligation.
Check the guarantee for an agreed different scope or ceiling.
Calculate the covered principal, interest and charges against those terms.
Check the applicable legal framework
This guide explains the central provision. Applicable State amendments, the agreement, transaction date and other governing laws can affect its application. Check the current legal framework before relying on it for a commercial decision.

Frequently asked questions
Can the guarantee limit liability?
Yes. The statutory default is expressly subject to contrary contractual provision.
Can interest and charges be included?
The illustration includes interest and charges due on the guaranteed bill; the actual instrument and guarantee still matter.
Does section 128 decide all enforcement procedure?
No. Other applicable laws and the transaction’s terms must also be considered.
