I am assuming you are the tenant.
I have also assumed its for rent arrears/breach of tenancy.
If you have been served a S.8 notice and in breach then sadly the Court does not have discretion.
If you are more than 8 weeks in arrears the Court will grant possession.
If the Landlord has served a S.21 notice, this is the Landlord just saying they want the property back
In order to do that you must have:
1) deposit protected
2) how to rent guide
3) EPC certificate
4) gas certificate if appropriate.
If you have not been served these, then the notice is not valid and the eviction can not proceed.
If the Court grants possession then the Court can give you 14-28 days to leave.
After that, if you do not leave, then the Landlord can get a warrant of eviction, which mean bailiffs can turn up and evict.
Can I clarify anything for you about this today, please?
If you need anything further I am available for a follow up at no extra cost.
