Form N11 vs Form N11R: Which Defence Form?

Short answer: if a residential possession claim is involved — a landlord recovering a rented property, or a tenant defending that claim — the correct defence form is N11R, not plain N11. Practice Direction 55A (paragraph 1.5) sets out four prescribed defence forms for possession claims: N11, N11B, N11M and N11R. Each covers a different type of possession case, and N11R is the one built for an ordinary claim for possession of rented residential premises. If a possession claim has been issued using Form N5 and Form N119 (particulars of claim for possession), the tenant's defence should be filed on N11R, not on the general N11 form.

The four possession defence forms

Practice Direction 55A, which supplements CPR Part 55 (possession claims), states plainly: "The claimant must use the appropriate claim form and particulars of claim form. The defence must be in form N11, N11B, N11M or N11R, as appropriate." All four are part of the same Part 55 possession framework — the difference is which type of claim each one is designed for:

• N11R — a claim for possession of rented residential premises. This is the form for an ordinary landlord-and-tenant possession claim, brought on Form N5 and Form N119.
• N11B — a claim brought under the accelerated possession procedure for an assured shorthold tenancy (i.e. a claim on Form N5B). We cover N5B separately on our accelerated procedure page.
• N11M — a claim for possession of mortgaged residential premises, brought by a lender rather than a landlord.
• N11 — the residual defence form, used for possession claims that don't fall into any of the three categories above.

So N11 isn't "the wrong court" or "a different track" in some general sense — it's one of the four prescribed possession defence forms, just not the one that applies to an ordinary rented residential tenancy claim. That distinction matters because it's easy to assume any of these four forms will do, when in fact the type of claim decides which one is correct.

What Form N11R is — and why it's the one that matters here

Form N11R is the defence form built specifically for a tenant responding to a residential possession claim brought under the standard procedure — started with Form N5 and supported by Form N119. We cover N11R in full detail, including how to complete it and how it interacts with the possession hearing, on our dedicated page: Form N11R: Defence Form for Rented Residential Possession Claims. If you've just been served with possession papers for a rented home, that page — not this one — is where you'll find the practical, section-by-section guidance.

N11R is structured around the questions specific to a residential tenancy possession claim: whether the tenant accepts they owe rent, whether they dispute the ground(s) relied on, what would happen to them if evicted, and (for discretionary grounds) circumstances relevant to whether it would be reasonable to make a possession order. Plain N11 doesn't ask these questions in the same way, because it's designed to cover a broader, more generic category of possession claim.

When plain N11 is the wrong form

If you are a tenant facing any residential possession claim — rent arrears, another discretionary ground, or a mandatory ground — plain N11 is the wrong form, and N11R is required instead. This applies whether the claim is defended in full, partly admitted, or used to raise a counterclaim (for example, about disrepair).

This trips people up for an understandable reason: all four forms share the "N11" prefix, all are broadly "defence forms" for possession claims, and a quick search for "N11 defence form" doesn't always surface the housing-specific version first. Landlords sometimes assume any defence document a tenant files is equivalent — it isn't, and the form used can affect how smoothly the claim proceeds.

What happens if the wrong form is filed

If a tenant files plain N11 in a claim that should have used N11R, the court is likely to notice the mismatch, since N11 doesn't collect the rented-residential-specific information the case needs. In practice, the court may direct that the correct form (N11R) be filed, causing delay while the tenant resubmits. This is normally a procedural correction, not a defence that automatically fails — under CPR 55.7, a defendant who hasn't responded on the correct form (or at all) can still take part in the hearing, though the court can take the failure into account when deciding costs. Landlords shouldn't assume the wrong form ends the claim in their favour, and tenants who've made this mistake shouldn't assume the case is lost. The sensible step is to file N11R as soon as the error is spotted, rather than waiting.

Time limits

A tenant generally has 14 days from service of the claim to respond. Possession claims work differently here from ordinary civil claims: CPR 55.7 specifically disapplies the usual Part 10 acknowledgment-of-service procedure and Part 12 default judgment. There is no Part 10-based route in a possession claim that extends the response deadline the way it can in an ordinary money claim — check the claim form and any court correspondence for the specific date. See our Form N9 page for what that form is used for where money is also claimed alongside possession.

Quick summary

• N11, N11B, N11M, N11R — the four prescribed defence forms for possession claims under Practice Direction 55A, each covering a different type of case.
• N11R — rented residential premises. This is almost always the form actually needed when a landlord is trying to recover a tenanted property, brought on Form N5 + N119.
• N11B — accelerated procedure (Form N5B) claims. N11M — mortgaged residential premises, used by lenders.
• Plain N11 is the residual form for possession claims outside those three categories — not the one for an ordinary rented residential claim.
• If in doubt, check whether the claim is a rented residential possession claim. If it is, use N11R and see our full N11R guide for how to complete it.

Frequently asked questions

Is N11 the same as N11R?

No. Both are prescribed defence forms for possession claims under Practice Direction 55A, but they cover different cases — N11R is for rented residential premises, while plain N11 is the residual form for possession claims outside that category (and outside the accelerated-procedure and mortgaged-premises categories too).

I've been served with a possession claim for my rented home — which form do I use?

Use Form N11R, not plain N11. Our N11R guide walks through how to complete it.

My tenant filed N11 instead of N11R — does that mean I win the claim?

Not automatically. Filing on the wrong prescribed form doesn't automatically dispose of the case in the landlord's favour — the court may direct the tenant to refile on N11R, which can delay the claim rather than end it.

How long does a tenant have to respond to a possession claim?

Generally 14 days from service of the claim. CPR 55.7 disapplies the ordinary acknowledgment-of-service (Part 10) and default judgment (Part 12) rules for possession claims, so there's no Part 10-based extension route the way there can be in an ordinary civil claim.

Where do I find the official forms?

GOV.UK hosts Form N11 and Form N11R as separate publications, and Practice Direction 55A (paragraph 1.5) sets out which of the four possession defence forms applies to which type of claim.

Does this page cover how to fill in N11R?

No — for step-by-step detail on completing N11R itself, see Form N11R: Defence Form for Rented Residential Possession Claims. This page exists only to clear up which of the four possession defence forms applies to an ordinary rented residential claim.
