A material breach is a failure to perform a contract that is serious enough to give the other party significant remedies, most importantly the right to terminate. It contrasts with a minor breach, which may support a claim for damages or a contractual remedy such as a service credit but usually doesn’t justify ending the contract. In IT and telecom contracts, material breach is the gateway to termination for cause: a buyer who can show it may be able to exit without the termination fees that would otherwise apply. Whether a breach is material depends on the contract wording, the facts and the governing law.
At a glance
- A material breach is serious enough to support major remedies, often including termination.
- Some contracts define specific material breaches; otherwise materiality is judged on the facts.
- Termination for material breach usually requires written notice and a chance to cure.
- An ordinary SLA miss is usually handled through credits, not treated as a material breach.
- Materiality depends on wording, facts and governing law. This is general information, not legal advice.
What problem it solves
Contracts need a threshold for when one party’s failure is bad enough that the other shouldn’t be held to the deal. Without one, a buyer could be stuck paying for a service that fundamentally doesn’t work, and a provider could be forced to keep serving a customer that doesn’t pay. Material breach sets that threshold, usually paired with a cure period so the breaching party has a chance to fix the problem first.
For buyers, the challenge is that “material” is often undefined, so whether a failure qualifies can become a dispute in itself.
How it works
Defined breaches. Some contracts list events that count as material, such as nonpayment after notice, breach of confidentiality or data protection terms, insolvency, or repeated failure to meet critical service levels. Defining them reduces arguments later. Insolvency or bankruptcy triggers may be restricted or unenforceable, including under US bankruptcy law (limits on such clauses and the automatic stay); have counsel review before acting on them.
Undefined materiality. Where the contract simply says “material breach,” a court or arbitrator decides under the governing law. Factors often considered include how much of the expected benefit the injured party lost, whether damages would compensate it, whether the breach can be cured and whether the breaching party acted in good faith. The tests differ between jurisdictions.
Notice and cure. Contracts commonly require written notice describing the breach and a cure period before termination. Some breaches, such as a data leak, may be treated as incurable, depending on the wording.
Remedies. Remedies can include termination for cause, damages subject to the limitation of liability, and, depending on the contract, release from the early termination fee (ETF).
Interaction with the SLA. The service level agreement (SLA) often states that SLA credits are the exclusive remedy for missed targets, which can limit claims that poor performance is a material breach.
Enforceability and interpretation depend on the governing law, the jurisdiction and the exact wording. This is general information, not legal advice; have counsel review the contract before claiming material breach.

When it matters for buyers
- Negotiating. Define the failures that matter most to you as material, so you don’t have to argue about it later.
- A failing provider. Before claiming breach, check the notice, cure and dispute resolution steps, and gather evidence.
- Performance problems. If outages are repeated, a chronic outage clause may give a clearer exit than arguing materiality.
- Your own obligations. Late payment or misuse of a service can be a material breach by the customer, giving the provider the right to suspend or terminate.
Questions to ask vendors
- Which events does the contract treat as a material breach, by either party?
- What notice and cure period applies before either party can terminate?
- Will repeated failure to meet critical service levels be treated as a material breach?
- If we terminate for your material breach, will early termination fees be waived?
- Can you suspend service for our breach, and with how much notice?
- Which breaches, such as security incidents, are treated as incurable?
How it differs from a missed service level
A missed service level is a failure to meet a measured target, such as uptime, and is usually handled by SLA credits under the SLA. A material breach is a failure serious enough to justify ending the contract. A single miss rarely qualifies on its own; contracts that want repeated misses to support termination usually say so explicitly, through a chronic outage clause or a defined material breach.
