How Wren helps with the FL431
Official forms are written for lawyers. With Wren you do not have to decode this one on your own, and you still follow the court’s procedure.
- Plain questions, one at a timeEach part of the FL431 becomes short questions in everyday words. Answer at your own pace and come back to it.
- Help beside each questionWhat the question is asking and what the official guidance says about it, in plain English.
- The official form, filled inYour answers go into the official FL431. You check it, sign it and send it yourself. Nothing goes to the court for you.
- What comes next, kept with your caseWhat usually happens after you send it, with the dates worked out from the published rules.
Time and money
- On your own
- A day or more
- With Wren
- About an hour for most forms
- Solicitor for this form
- £740 to £1,2403 to 5 hours
A solicitor’s time for the FL431 can run to £1,240. With Wren it is part of £19.99 a month, and it takes about an hour for most forms rather than a day or more.
Times and hours are Wren’s estimates for a typical case, not quotes. Solicitor costs are those hours at £247 an hour, the courts’ guideline rate for a solicitor with over four years’ experience, outside London (GOV.UK, Solicitors' guideline hourly rates (in effect from 1 January 2026)). The guideline runs from £200 to £295 an hour outside London depending on experience, firms set their own rates, and VAT is added on top.
