What the checker looks for
- Laws it names. More than twenty Acts, regulations and schemes that come up in tenant complaints in England, each with a note on what it covers and a link to the source.
- Law that’s often misapplied. A flag when a complaint relies on something that doesn’t apply to a private let in England, or isn’t law at all: Awaab’s Law, Welsh or Scottish housing law, the Renters (Reform) Bill, section 21 after 1 May 2026, and parts of the Renters’ Rights Act that aren’t in force yet.
- Sentences that state a legal rule. Any sentence that says the law requires or entitles something (“by law”, “you are required to”, “I am entitled to”, “under the … Act”), so none gets missed.
- The issues it raises. Repairs, damp, deposits, fees, rent, notices, access, pets and more, each with the records that usually settle it.
- Deadlines, sums and escalation. “Within 7 days”, compensation figures, and mentions of the ombudsman or the courts.
- Dates. To line up against your own records.
What it can’t tell you
This is a quick check that recognises words and phrases. It doesn’t read the legislation, so it can’t tell you whether a legal claim is right, whether a section says what the complaint says, or what you should decide. Treat what it finds as a list of things to check, not as answers.
For the checks themselves, see When an AI complaint quotes the wrong law. For the whole process, see the complete guide to AI-generated complaints.
Your text stays in your browser
The checker is a small script that runs on your own device. What you paste isn’t uploaded, logged or stored, and it’s gone when you leave the page. Even so, it’s good practice to take out names, addresses and phone numbers first. The checker doesn’t need them.
From a quick check to a full answer
Casebriar does the part this checker can’t. It separates the complaint into every issue and point, checks each legal claim against the provision on legislation.gov.uk (the wording, England, and the date), lists the records each issue needs and reads the documents you add. Then, once you’ve decided each issue, it drafts the reply. Open the sample case to see it on a long, heavily worded complaint, or start with a single complaint for £13.
