Challenging a section 21 notice in court
The law has changed
You can only be evicted with a section 21 notice if your landlord gave you a valid notice before 1 May 2026.
This advice is for private tenants.
When the court can stop your eviction
Your landlord has to apply for an eviction order from a court.
The court can stop your eviction if:
your section 21 notice is not valid
your landlord applies for an eviction order too late
Not valid means there is a problem with the notice.
Check if your notice is valid.
A court should not evict you if the notice is not valid.
Your landlord cannot give you another section 21 notice after 1 May 2026.
Is your landlord too late to go to court?
Your landlord cannot apply for an eviction order after 31 July 2026.
Some landlords have to apply before this date. It depends on when they gave you the notice.

Table: Latest date your landlord can apply for an eviction order
| Date you were given the section 21 | When court action must start by |
|---|---|
| Before 1 February 2026 | Your landlord must start court action within 6 months of giving you notice |
| On or after 1 February 2026 | Your landlord must start court action by 31 July 2026 |
If your landlord does not apply for an eviction order, you become an assured tenant.
That means your landlord needs a reason to evict you. For example, rent arrears.
Check the court forms
Keep all your papers from the court together in a file.
The forms help you work out which eviction process your landlord is using.
It could be either the:
accelerated procedure
standard procedure
The main difference is you may not have a court hearing with the accelerated procedure.
Accelerated procedure
The court sends you these forms:
N5B claim form
It is important to return your defence form if either:
you think the section 21 is not valid
you need a short delay in the eviction process
Return your defence form within 2 weeks
Use the form to tell the judge why your section 21 notice might not be valid. They must arrange a hearing if there's a problem with the notice.
Standard procedure
The court sends you these forms:
N5 claim form
Go to the hearing even if you do not return your defence form.
The date, time and address are on the claim form.
There is always a court hearing with the standard procedure.
If you need an interpreter
You can get a free interpreter for the hearing if either:
you do not understand English
you're Deaf and use British Sign Language (BSL)
You can also ask the judge to let a friend or family member explain what the judge says in your own language.
Free interpreters at court
Contact the court before the hearing to tell them you need this service.
If you cannot find legal help before the hearing
You should still go to your court hearing.
You can usually speak to a court duty adviser before you see the judge.
Free legal help at court
You can get free legal help on the day.
Ask to speak to a court duty adviser as soon as you get there.
Your court hearing
Your hearing is usually at your local county court.
You should:
get there at least 30 minutes early
ask for the court usher
wait to see the judge
A court usher tells you where to go and what to do. Ask them about the court duty adviser.
The hearing itself only takes about 10 minutes.
A judge will usually either:
make an eviction order if the section 21 notice is valid
say you can stay in your home if the section 21 notice is not valid
More on what happens at an eviction hearing.
If the judge says you must be evicted
The judge sets a 'possession date' on the eviction order.
This date is usually 2 weeks from when the order is made.
You can ask for up to 6 weeks if it would cause you 'exceptional hardship' to leave before this.
For example, if you are disabled or have serious health problems and would be homeless.
If you do not leave by the date on the order
Your landlord can ask court bailiffs to evict you.
It may be a few weeks before the bailiffs write to you with an eviction date.
Bailiffs must give you at least 2 weeks' notice of when they will evict you.
Find out what happens on the eviction date.
Who pays the costs of eviction?
If the court makes an eviction order, you usually have to pay:
your landlord's court fees
some or all of their legal costs
You might have to pay at least £666 if there is a hearing and you are evicted by bailiffs.
