Challenging a section 21 notice in court
The law has changed
Private tenants can only be evicted with a section 21 notice if both these things apply:
you got a valid notice before 1 May 2026
your landlord applied for an eviction order before 1 August 2026
Housing associations can still give section 21 notices to some tenants.

Is your private 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 have started by |
|---|---|
| Between 1 February and 30 April 2026 | By 31 July 2026 |
| Before 1 February 2026 | Within 6 months of giving you notice |
If your landlord did not apply for an eviction order in time, you are an assured tenant.
This means your landlord needs a reason to evict you. For example, rent arrears.
Check if your notice is valid
The court can stop your eviction if your section 21 notice is not valid.
Not valid means there is a problem with the notice.
For example, if your landlord:
gave it on or after 1 May 2026
did not use Form 6A
gave you less than 2 months' notice
gave you notice in the first 4 months of your tenancy
A few other things could make your notice not valid.
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.
Prepare for the hearing if there is one
You should take these things with you:
your tenancy agreement
your section 21 notice
court letter and defence form
proof that you paid a deposit if it is not protected
You might also need to:
book time off work
arrange childcare
ask someone to pick up your children from school
think about travel time or parking at the court
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 with the judge only takes about 10 minutes.
Tell the duty adviser and the judge if you think there is a problem with the notice.
The 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
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.
You might have to pay some or all of their legal costs.
This could be several hundred pounds. But you can pay it in instalments if you cannot pay this all at once.
Get free legal advice
Look for help as soon as you get a notice.
Find a legal adviser on GOV.UK.
Tick 'housing loss prevention advice service' on the search tool.
You could get more legal help if you get benefits or have a low income.
Help from the council
You do not need to wait to be evicted to ask for help.
