A contract can look perfectly sound at first glance and still contain errors that completely change how it is read. In international settings, one of the most common — and most expensive — failures is the misuse of false friends. In this article you will see how they really affect contracts drafted in English, what risks they create and how to avoid them before they turn into a legal or financial problem.
What false friends are and why they are a genuine risk
In a business context, false friends are not merely a linguistic curiosity. They are words that look alike in two languages but carry different meanings, which can lead to critical mistakes.
In a contract, where every term has legal implications, that kind of confusion can:
– Alter the obligations between the parties
– Create ambiguity in key clauses
– Trigger disputes over interpretation
For example, a Spanish speaker who writes actual in English instead of current may seem to be splitting hairs, but in a contractual document it can create confusion about deadlines or the conditions in force.
Where they turn up most often in international contracts
False friends tend to slip into the critical parts of a contract, especially where there is no specialist linguistic review.
Financial clauses and commercial terms
Wording covering prices, payments or terms of business can all be affected.
A common example: using eventually in the belief that it means “possibly”, when it actually means “in the end”. That can change how future commitments are understood.
Description of responsibilities
Errors in key words can change who is responsible for what.
Example: assist does not mean “to be present at”, but “to help”. A misreading can create the wrong expectations about one party’s role.
Sensitive legal terms
In legal language, precision is essential.
Example: sensible does not mean “sensitive”, but “prudent” or “reasonable”. In a legal context, that can change how decisions or expected conduct are interpreted.

Real consequences for the company
The impact of these mistakes is not theoretical. It has direct effects on business, relationships and legal certainty.
Legal risk and contractual disputes
A misreading can lead to disagreement over what was actually signed. That can end in renegotiation, delay or even litigation.
Loss of professional credibility
A contract containing language errors signals a lack of rigour. In international settings, that shapes how the company is seen.
Hidden financial costs
Fixing errors after a contract has been signed is far more expensive than preventing them. It can mean extra legal advice, project delays or lost opportunities.
Concrete examples of problematic false friends
To grasp the real impact, it helps to look at cases that come up regularly in business English:
– Actually → does not mean “currently”, but “in fact”
– Library → is not a bookshop, but a lending library
– Fabric → does not mean “factory”, but “cloth”
– Exit → does not mean “success”, but “way out”
In a contract, these errors are not trivia. They can change the meaning of an entire clause.
Picture a technical specification that refers to fabric. Reading that as “factory” rather than “material” can cause problems when the product is delivered.
Why these errors happen in companies
They are rarely a matter of not knowing the language at all, but of overconfidence.
Literal translation
Many companies translate documents in-house without checking them against the context. That raises the risk of false friends.
Reliance on automated tools
Machine translation has improved, but it still fails in legal or technical contexts when there is no human review.
No specialist review
A contract should be reviewed not only from a legal standpoint, but from a linguistic one too.

How to avoid false friends in international contracts
These errors can be prevented if certain processes are built into the company.
Review by language specialists
Working with professionals who master both the language and the business context reduces the risk considerably.
Legal and linguistic teams working together
The legal team should work alongside language experts to make sure the meaning survives in both languages.
Building in-house glossaries
For companies that work across several languages on a regular basis, an approved glossary prevents inconsistency.
Training the team
The aim is not to turn everyone into a linguist, but to make sure they can spot the basic risks.
That matters especially for sales, legal and operations roles.
A worked example: how one false friend changes a contract
A Spanish company signs an agreement with a British partner. One clause states that an action will be carried out “eventually”.
The Spanish team reads that as “possibly, at some future point”. The British partner understands it as “definitely, though later on”.
The result: two different sets of expectations about a key obligation. That leads to conflict and the need to renegotiate.
Situations like this are more common than they appear.
Frequently asked questions
Yes. In legal documents, any ambiguity can create conflict. False friends are a frequent source of error.
Not always. Even people with a strong command of the language can make these mistakes without experience in contractual wording.
Particularly those operating internationally, signing contracts in English or working with foreign suppliers and clients.
False friends are no minor detail in international contracts. They can affect interpretation, create conflict and have a real financial impact.
Avoiding them depends not only on your level of English, but on working with judgement and the right support behind you. At ALOS we help companies improve their professional English, reducing risk and building confidence in international settings.
