Here is the fear that lands in our inbox most often from unmarried-partner applicants: two years of WhatsApp messages, thousands of them, half in another language, and the dread of paying to translate every single one. You don't have to. UKVI does not want your complete chat archive, and it does not want a word-for-word translation of two years of good-morning texts. It wants a representative, organised selection that shows a genuine, subsisting relationship — and most of what couples send each other never needs translating at all. Knowing what to translate, and what to leave alone, is the difference between a £60 job and a £600 one.
No. UKVI wants a representative selection of communication spread across the relationship, not the entire archive. You curate a sample — typically a handful of exchanges per month or per significant period — and only the non-English portions of that sample need certified translation. Translating thousands of messages in full is unnecessary and is not what caseworkers expect.
The unmarried-partner route asks you to show a genuine relationship that has subsisted for at least two years, usually with evidence of living together. Communication evidence is one strand of that, alongside cohabitation and finances. Caseworkers are looking for a pattern across time, not volume.
The practical approach is to curate before you translate. Choose a manageable selection — many applicants include something from each month, or cluster exchanges around real events (a trip, a birthday, a visa-application period, time spent apart). The goal is to demonstrate continuity and ordinariness over the two years, not to prove you texted constantly.
From that curated selection, only the non-English content actually goes to the translator. A great deal of couple-to-couple messaging is already in English, or in a mix where the meaning is plain. You are paying to translate words, by the page, so the smaller and better-chosen the selection, the lower the cost — and a tight, legible selection reads better to a caseworker than a thousand-page data dump nobody can navigate.
What doesn't help is submitting the raw export of an entire two-year chat in another language and expecting UKVI to wade through it. That invites a request for further information, not a grant.
Only evidence you are relying on that is wholly or partly in a non-English language: foreign-language letters from family, money-transfer and remittance receipts, joint tenancy agreements and utility bills, and official documents recognising the relationship. Anything already in English — including English-language messages, emails and UK bills — needs no translation.
It helps to sort your evidence into what UKVI is assessing rather than by what app it came from. The unmarried-partner relationship is usually evidenced across a few categories, and the translation question is the same for each: is this document in English or not?
Communication evidence: chat logs, call records, emails. Translate only the non-English parts of your curated selection.
Cohabitation evidence: a tenancy agreement, utility bills, bank correspondence, or letters addressed to both of you at the same address. If these were issued in another country in another language, they need certified translation. UK-issued documents in English do not.
Financial interdependence: money transfers between you, remittance receipts, shared expenses. Transfer receipts from services like Western Union, Wise or a foreign bank are often partly in another language and are worth translating because they carry dates, names and amounts that directly support the relationship timeline.
Recognition by others: letters of support from family and friends, and any official acknowledgement of the relationship. A letter written in another language by a parent confirming they know the relationship is useful evidence — but only if it is translated, because a caseworker cannot weigh what they cannot read.
The single rule underneath all of this: a document in a foreign language carries no evidential weight with UKVI until it is accompanied by a certified English translation. Translate what matters; leave the English alone.
The translator works best from a clean text export of the conversation, not from screenshots. They translate the non-English portions, preserve the timestamps and sender labels, and add a certified note explaining how the selection was made and how mixed-language or romanised text (Hinglish, romanised Urdu, Arabizi) was handled. A statement of accuracy makes the whole selection UKVI-compliant.
Start with the export, because it determines everything downstream. WhatsApp's own 'Export chat' function (without media) produces a dated text file that a translator can work through cleanly, keeping every message attributed and time-stamped. That structure matters: UKVI is looking at the pattern over time, so preserving dates and who-said-what is part of the evidence, not decoration.
Screenshots are the harder route. They scatter the conversation across dozens of images, lose easy date ordering, and force the translator to transcribe before translating — which costs more and reads worse. Screenshots are fine for a short, pointed exchange; for anything spanning months, the text export wins.
Mixed and romanised language is the part applicants worry about most, and translators handle it every day. Couples code-switch: a single message might run English, then romanised Urdu, then an emoji. Real relationships are written in Hinglish, in Arabizi (Arabic typed in Latin letters and numbers), in romanised Tagalog or Thai. The translator renders the non-English content into English, notes where transliteration was involved, and flags anything genuinely ambiguous rather than guessing. Emoji are left as they are — they carry across languages and don't need translating.
The certification ties it together. The certified translation includes a statement of accuracy and a translator's note that explains the selection (for example, 'representative exchanges selected across the period March 2024 to March 2026') and the approach to mixed-language text. That note is what turns a pile of messages into evidence a caseworker can rely on, and it's why the translation has to come from an independent qualified translator — not from you or your partner, however fluent. Self-translated evidence carries no independent weight.
A well-curated bundle of relationship evidence is usually 10–30 pages once trimmed to the non-English content, and runs roughly £150–£400 at standard UK certified rates, with bundle pricing bringing the per-page cost down. Turnaround is typically 2–4 working days. Curating before you send is the single biggest lever on price — translating the raw archive can cost ten times as much for weaker evidence.
Certified translation is priced by the page, so the page count after curation is what drives the cost, not the size of your phone's chat history.
A focused communication selection, once the English is stripped out and only the non-English exchanges remain, often comes to 5–15 pages. Add a handful of money-transfer receipts (usually under a page each), a foreign tenancy agreement (2–4 pages), and two or three family letters of support (1–2 pages each), and a typical unmarried-partner evidence bundle lands in the 10–30 page range.
At standard UK certified rates, with the bundle pricing most providers apply to multi-document orders, that's commonly £150–£400 for the translated relationship evidence. Same-week turnaround is normal; 2–4 working days is typical for a bundle of this size, with faster options if your submission date is close.
The expensive mistake is skipping the curation step. Sending a translator the full two-year export of a daily conversation can run to hundreds of pages and many hundreds of pounds — for evidence that is actually weaker, because a caseworker can't find the signal in it. Trim first, translate second. You'll spend less and submit something stronger.
Correct. UKVI assesses whether a relationship is genuine and subsisting, and looks for a representative pattern over time, not a complete transcript. Curate a selection spread across the two years and translate only the non-English parts of it. A full-archive translation is unnecessary and harder for a caseworker to use.
No. UKVI requires translations of foreign-language evidence to come from an independent qualified translator with a statement of accuracy. A translation by you or your partner has no independent weight, however fluent either of you is, because you are not a neutral third party.
Translators handle code-switching routinely. They render the non-English content into English within the message, keep the English as it is, and add a note where transliteration (such as romanised Urdu or Arabizi) was involved. The timestamp and sender stay attached so the exchange still reads in sequence.
Both can be certified, but a text export ('Export chat' without media) is better for anything spanning months: it keeps messages dated and ordered, costs less to translate, and reads more clearly. Screenshots are fine for a short, specific exchange.
Effectively, yes. A document in another language carries no evidential weight until it has a certified English translation. Untranslated chat logs, receipts or letters can't be assessed, so they don't help your case — translate the parts you're relying on.
There's no fixed number. Aim for continuity over volume: a few exchanges per month, or clusters around real events across the two years, are more persuasive than a dense block from a single period. Choose quality and spread over quantity.
