The legal rule
For arrears cases, the key grounds are Ground 8, Ground 10 and Ground 11. The form materials identify Ground 8 where there are serious rent arrears and Grounds 10 and 11 where there are some arrears or a persistent pattern of late payment.
Ground 8 - the real possession ground
Ground 8 is the serious arrears ground. In practical landlord terms this is the ground that usually carries the real possession weight in arrears cases. If you are going to court for arrears possession, this is normally the ground you want to be able to prove cleanly.
Ground 10 - some rent lawfully due
Ground 10 is useful where some rent is unpaid. It helps show there are arrears, but by itself it is discretionary and much weaker than Ground 8.
Ground 11 - persistent delay
Ground 11 helps where the tenant is repeatedly late paying rent. This is valuable in building a pattern of conduct, but again it is discretionary and not the same thing as having the stronger arrears threshold position.
PIMS normal arrears position
PIMS recommends landlords understand that Grounds 10 and 11 can be used before the arrears position becomes serious enough for Ground 8. In that earlier phase they are often better seen as pressure and negotiation grounds rather than the real court-winning possession grounds.
- Ground 8 = possession engine.
- Ground 10 = supporting arrears ground.
- Ground 11 = supporting conduct ground.
Why claims fail here
- Landlord assumes Ground 10 or 11 is strong enough alone for court.
- Landlord does not understand the difference between mandatory and discretionary grounds.
- Arrears figures are weak, unclear or inconsistent.
- The notice is served before the file is truly ready.
What the tenant is told
The tenant guidance tells tenants that mandatory grounds mean the court must make an order if a valid notice and at least one mandatory ground are proven, while discretionary grounds depend on whether the court thinks it is reasonable in the circumstances.
PIMS Tip: For rent arrears, do not confuse a useful pressure ground with a reliable possession ground.
