Tenants and joint renters in Wales sometimes face issues when one household member is accused of prohibited conduct under a tenancy, such as antisocial behaviour, deliberate damage, or illegal activity. This guide explains what 'prohibited conduct' can mean, when you should notify joint holders named on the tenancy, and what actions landlords may take. It covers how to preserve your rights, the official notices and forms involved, and practical steps to raise a dispute with the First-tier Tribunal (Property Chamber). Use this information to respond calmly, collect evidence, and follow official procedures so you protect your home and tenancy record.
What counts as prohibited conduct
Prohibited conduct is behaviour set out in law or in your tenancy agreement that can justify a landlord taking action. Common examples include persistent antisocial behaviour, intentional serious damage to the property, or criminal activity carried out from the home. Landlords use the legal framework in the Housing Act 1988 when deciding on possession grounds and notices.[1]
Notifying joint holders and your practical steps
If you are a joint tenant you are jointly responsible for the tenancy contract but each named holder should be told about allegations that may affect the tenancy. If a landlord alleges prohibited conduct they should notify all named tenants and follow official notice procedures; details and templates for notices are available on GOV.UK.[2] If you disagree with the allegation you can collect evidence, send a written response, and request that the landlord uses mediation or refers the matter to the First-tier Tribunal (Property Chamber).[3]
- Read the allegation carefully and note dates, times and witnesses.
- Save copies of messages, photos and any evidence that supports your side of the story.
- Respond in writing within any stated deadline and ask for clarification if details are unclear.
Official forms you may see
- Section 8 notice (notice seeking possession): used when a landlord relies on specific statutory grounds for possession, for example serious antisocial behaviour; a tenant example: your landlord serves a Section 8 after repeated noise complaints, and you should check the grounds and deadline. See official guidance for the required wording and process.[2]
- Section 21 notice (Form 6A for assured shorthold tenancies): used for no-fault possession in some circumstances; if a joint tenant receives Form 6A, both named holders should check whether the notice is valid and if any conditions (such as deposit protection) were met. Practical example: one joint tenant is leaving but the landlord uses Form 6A to seek possession of the whole property. See GOV.UK for current form requirements.[2]
- Possession claim forms (court forms such as N5): if the landlord applies to the court or tribunal for possession you may see a claim form; respond promptly and consider seeking advice before the hearing. The official process and templates are explained on GOV.UK.[2]
When to contact the tribunal
If you cannot resolve the dispute with your landlord, you may apply to the First-tier Tribunal (Property Chamber) which handles many private residential tenancy disputes for England and Wales. The tribunal can consider evidence from all joint tenants and decide on possession, compensation or conditions attached to a tenancy.[3]
FAQ
- Do I need to tell my co-tenant if the landlord accuses only one name on the tenancy?
- Yes. Both joint holders should be notified because the tenancy agreement names all tenants and actions may affect everyone on the contract.
- Can a landlord evict just one joint tenant for prohibited conduct?
- Landlords usually seek possession of the whole tenancy. In limited circumstances they may apply for replacement of a tenant, but you should get advice and attend any tribunal to explain your situation.
- What evidence helps if I dispute an allegation?
- Written messages, timestamps, photos, CCTV, witness statements and receipts for repairs can all support your case at a tribunal or in negotiations.
- How long do I have to respond to a notice?
- Deadlines vary by notice type; check the notice carefully and act quickly—if in doubt, use the official GOV.UK guidance and seek advice.
How-To
- Read the notice carefully and note any deadlines or hearings.
- Collect and save all relevant evidence such as photos, messages and witness details.
- Send a clear written response to the landlord, copied to any joint holders, and keep a dated copy.
- If unresolved, apply to the First-tier Tribunal (Property Chamber) or attend the hearing with your evidence.
Key Takeaways
- Notify and involve all joint holders named on the tenancy as soon as possible.
- Follow official notice forms and timelines to protect your rights.
