Absolutely — and if you already signed one, plain-language rules may still protect you.
Yes — you can always refuse to sign anything, for any reason, including simply not understanding it. No one can force you to enter a contract, and walking away or asking for time, a translation, or a trusted person's help is entirely your right. The harder question is what happens if you've already signed something you couldn't read: ordinary contract law generally still holds you to what you signed, but UK consumer protection law adds an important separate safeguard around how clearly contract terms must be written.
| Legal principle | What it means for you |
|---|---|
| General contract law: signature = agreement | Courts generally hold you to what you signed, even if you didn't read or understand it, in an ordinary contract |
| Consumer Rights Act 2015: transparency requirement | A written consumer contract term must be in plain and intelligible language to be treated as fair |
| Ambiguity rule | Where a term could reasonably mean more than one thing, the meaning most favourable to you as the consumer applies |
These two principles pull in different directions, and that tension is exactly the space where a genuine language barrier becomes legally relevant. A signature doesn't retroactively make dense, inaccessible wording "plain and intelligible" — the transparency requirement is assessed on the document itself, not on whether you happened to sign it anyway.
If you're a consumer (not signing as a business) and a term genuinely wasn't presented in a way you could reasonably understand, you have grounds to argue that specific term isn't binding on you under the Act's fairness and transparency rules — separate from whatever ordinary contract law would otherwise say about signatures. This is strongest where the term in question is a significant one (a fee, a penalty, a restriction on your rights) rather than a routine, boilerplate clause.
