WhatsApp messages in a builder or landlord dispute
Last reviewed 30 October 2026
Short answer: Keep the whole chat, export it early, then pick the few messages that show what was agreed and when. A short, dated record is easier for a scheme, adjudicator or judge to follow than a long chat. Check the rules of whoever will decide your dispute.
Builders and landlords often agree things over WhatsApp: quotes, start dates, repairs, notice. If it goes wrong, those messages can matter. This page is general information, not legal advice.
Why a short record helps
Short answer: People deciding a dispute are usually reading a lot of paperwork. A clear set of dated messages with a short note on each makes your point easy to follow and easy to check.
If a deposit scheme, adjudicator or court is going to decide, read their own guidance on what they ask for and how they want it sent. We have not checked any scheme's rules for this page.
A dump of 3,000 messages makes the reader hunt. A page of eight chosen messages, in date order, with a line saying why each matters, does not.
What to keep
Short answer: Keep the original chat on your phone, an unedited export, and any photos, voice notes, quotes and invoices that go with it. Do this before you delete or change phones.
- The whole chat, not just the good bits. It shows the context.
- The exported file, unchanged.
- Photos of the work or the property, in their original form.
- Voice notes, as the original audio. See turning voice notes into a transcript.
- Quotes, invoices, receipts, tenancy agreements and inventories.
If you have only screenshots, keep them, and also export the chat. See screenshot or WhatsApp export?.
Builder and trades disputes: what to pick
Short answer: Pick messages that show the price, the agreed scope, the dates promised and any change to either. These are what most trade disputes turn on.
Useful moments:
- The quote or price, and any message that changed it.
- What was agreed to be done, and what was left out.
- "Done by Friday" style promises, and the later messages when it was not.
- Photos sent of the problem, and the reply.
- Any request to put it right, and the response.
Put them in date order. One line each: "Agreed price", "Date promised", "Problem reported".
Landlord and tenant disputes: what to pick
Short answer: Pick messages about repairs reported, notice given, rent, move-in or move-out condition, and the deposit. Show when you reported something and what came back.
Useful moments:
- The date you reported a fault, and any reply.
- Arrangements for access or inspections.
- Messages about notice, rent changes or the end of the tenancy.
- Anything said about the condition of the property or the deposit.
Rules and deadlines for deposits and notices vary by place. Look at your scheme's or tenancy body's own pages for what applies to you.
Make one clear record
Short answer: Export the chat, pick the messages that matter, and turn them into a dated PDF with the full chat attached. VaultXT does this on your device, so your messages are not uploaded.
- Export the chat. Steps here.
- Open Make a pack. Tap the first and last message of each moment and add one line.
- VaultXT makes key messages, a timeline and the full chat as dated, numbered pages.
- Run Check a pack to confirm every quote matches the original.
The result is a tidy record. It does not decide what the person reading it will accept, and it does not make a message more genuine. VaultXT is not a law firm and does not give legal advice.
Questions people ask
Can I use WhatsApp messages in a deposit or builder dispute?
They are a record of what was said and when. Whether they are accepted and how much weight they carry is up to whoever decides. Read their guidance first.
Should I send the whole chat or just some messages?
Keep the whole chat. Send what the other side or decider asks for, usually the relevant parts, with the full chat available.
What if the other person deleted their messages?
Your copy still shows what you sent and received. Keep your phone and your export.
What about calls?
Calls are not in the export. Write down the date and what was said soon after, and keep the note.
Do I need a solicitor?
Not always. For a small claim or a scheme decision, many people manage alone. If a lot of money is at stake, consider advice.
