How to spot one-sided liability clauses in contracts

27 October 2026 · 3 min read

A liability clause defines who pays when things go wrong. In a balanced contract, each party takes responsibility for their own mistakes or breaches. However, many standard-form agreements contain one-sided liability clauses designed to shift almost all risk onto the smaller party or the service provider. Identifying these imbalances before you sign is essential for protecting your business from disproportionate financial exposure. This guide explains the specific language and structures used to create these one-sided terms.

Look for the absence of reciprocity

The quickest way to spot a one-sided clause is to check if it applies to both parties equally. Often, a contract will state that 'The Client shall indemnify the Provider against all losses,' but will not contain a matching clause where the Provider indemnifies the Client. If the obligations only flow in one direction, the clause is fundamentally biased.

Check for phrases like 'solely responsible' or 'at its own expense.' These are indicators that one party is being singled out to bear the weight of legal costs, damages, or third-party claims, even in situations where both parties might have contributed to the issue.

Identify asymmetric liability caps

A liability cap limits the total amount one party has to pay in damages. One-sidedness often hides in the numbers. You may find that your liability is 'uncapped'—meaning there is no limit to what you might owe—while the other party has capped their liability at a very low figure, such as the total value of the fees paid in the last month.

Compare the following markers to see if the risk is unfairly distributed:

  • Uncapped liability for 'consequential' or 'indirect' losses for one party only.
  • Extremely low financial ceilings for the drafting party (e.g., £100 or 'the price of the goods').
  • One party being required to hold high-value insurance while the other party excludes all liability for their own negligence.
  • Broad definitions of 'losses' that include loss of profit, loss of data, and reputational damage for one side but not the other.

Examine the scope of indemnities

Indemnity clauses are the most dangerous form of liability because they require you to compensate the other party for specific losses on a pound-for-pound basis, often bypassing the usual legal requirements to prove that the loss was foreseeable. A one-sided indemnity is often drafted with 'blanket' language.

Look for words like 'arising out of or in connection with' or 'howsoever caused.' These phrases are designed to catch every possible scenario, regardless of whether you were actually at fault. If you find yourself indemnifying the other party for 'acts or omissions' without the word 'negligent' preceding it, you are likely taking on a one-sided burden of risk.

Reviewing terms with practical tools

Contract review is often time-consuming, and human error can lead to missing subtle shifts in wording that drastically increase your risk profile. While manual review is important, modern services can help flag these issues more efficiently.

For those who need to quickly identify unfair risks, Jittan offers ContractChecker. This service reviews contracts, terms, and agreements for red flags, fairness issues, and practical points to consider, helping you catch one-sided liability clauses before they become a legal reality.

Identifying one-sided liability clauses requires a methodical approach to reading terms and an eye for missing reciprocity. By spotting these red flags early, you can negotiate fairer terms that protect your business from unmanageable financial risk.

Quick answers

Can a one-sided liability clause be challenged in court?
In the UK, the Unfair Contract Terms Act 1977 (UCTA) and the Consumer Rights Act 2015 provide some protection against 'unreasonable' terms. However, in business-to-business (B2B) contracts, courts usually assume both parties are sophisticated enough to negotiate, making it much harder to overturn a signed agreement.
What is the difference between a liability cap and an indemnity?
A liability cap sets a maximum ceiling on the damages you pay. An indemnity is a promise to reimburse the other party for specific losses. A one-sided contract often uses an indemnity to create a high risk and a cap to limit the other party's own exposure.
How can I make a one-sided clause fairer?
The simplest way is to ask for 'mutuality.' If a clause says you will indemnify them, suggest that the clause is amended to say 'Each party shall indemnify the other.' You should also aim to cap your total liability at a sensible multiple of the contract value.
