When a fourth occupant left last year the remaining three offered to pay the rent for the vacant room so there is a precedent
I think as long as the lease says it is one payment you are probably OK.
For example, it is possible to have one tenancy for each room, but that is clearly not what you set up with the lease.
Really, you have to decide what you want to do.
If you want to keep renting out the house, then you can send them a formal notice that they are in arrears, and threaten eviction. They might decide to just pay the rent and you are back to the status quo but with each paying half of the rent.
If you want to evict, then you need a justification. Failure to pay the rent is a valid reason, but they may decide to just pay it.
The valid reasons are as follows. Evict to sell and evict for landlord/family move-in are probably the easiest ones, depending on circumstances.
No fault
- Evict to sell (must sell within 9 months)
- Landlord or family move-in (niece/nephew or closer) (must actually "use" the house)
- Substantial refurbishment
- No longer suitable (e.g. overcrowding)
- Change of use
Tenant Fault
- Failure to pay rent
- Tenant breech of tenancy conditions
No matter what, you need to register the tenancy. You can't issue any official notices without an RTB registration.
There is a fine and also make sure you get the tenancy start date right so it counts as a pre-March tenancy.
It looks like late fees are €10 per month (or part thereof) but any time between 12 November 2022 and 1 March 2024 is excluded.
