Find out which notice you need
  • Mandatory grounds: If proven, the court must order possession
  • Discretionary grounds: The court considers if it's reasonable to order possession

You can use multiple grounds in the same claim if several apply to your situation.

Mandatory Grounds

With mandatory grounds, if you prove the ground exists at the hearing, the court must order possession. There is no discretion.

Serious Rent Arrears (Ground 1)

This is the most commonly used mandatory ground. Requirements:

  • At least 2 months' rent must be outstanding
  • Arrears must exist at the date of the notice AND at the hearing
  • Only 14 days' notice is required

Arrears Must Persist

If the contract-holder pays down the arrears to below 2 months before the hearing, this ground fails. You would need to rely on discretionary grounds instead.

Other Mandatory Grounds

  • Death of contract-holder: Where there is no successor
  • Prohibited conduct (final warning): After formal warning for serious issues

Discretionary Grounds

With discretionary grounds, the court considers whether it's reasonable to order possession, even if the ground is proven.

Discretionary Grounds Wales
Courts weigh up all circumstances with discretionary grounds

Breach of Contract (Ground 12)

The contract-holder has breached a term of the occupation contract. Examples:

  • Unauthorized subletting
  • Keeping pets contrary to the contract
  • Running a business from the property
  • Causing damage beyond fair wear and tear

Anti-Social Behaviour (Ground 13)

The contract-holder (or their visitors) has engaged in anti-social behaviour. This includes:

  • Noise nuisance affecting neighbours
  • Harassment of neighbours
  • Criminal activity at the property
  • Violence or threats of violence

Evidence is Key

For anti-social behaviour, you'll need strong evidence such as incident logs, witness statements, police reports, or local authority records.

Some Rent Arrears (Section 8 notice guide)

Any rent is outstanding. Unlike the mandatory ground, there's no minimum amount, but the court considers whether it's reasonable to evict.

Estate Management Grounds

These grounds relate to the landlord's plans for the property:

Landlord Wants to Sell (Ground 3)

  • You intend to sell the property
  • Sale would be significantly harder with tenant in situ
  • 6 months' notice required

Landlord Wants to Live There (Ground 4)

  • You or a family member intends to live in the property
  • Must be a genuine intention
  • 6 months' notice required

Major Works Required (Ground 5)

  • Substantial works are needed that require vacant possession
  • Works cannot reasonably be carried out with tenant present
  • 2 months' notice required

Possession Grounds FAQ

Can I use multiple grounds in one claim?

Yes. You can rely on multiple grounds in the same claim. This is often advisable as a backup - for example, claiming serious arrears (mandatory) and some arrears (discretionary) together.

What factors does the court consider for discretionary grounds?

The court considers all circumstances including: the severity of the breach, whether it's ongoing, the tenant's housing needs, any vulnerability, and whether the landlord has contributed to the situation.

Can I evict for a single incident of anti-social behaviour?

Possibly, if it's serious enough. A single serious incident (like violence) could justify eviction. Minor one-off incidents are less likely to succeed as courts want to see a pattern or serious harm.

Do I need to prove I really want to sell/live there?

Yes. For estate management grounds, you must demonstrate a genuine intention. If you claim you want to live there then immediately re-let, the tenant could claim damages for misrepresentation.
