Form N121: Particulars of claim (Trespassers)

Form N121 is a UK court form used by landlords to make a claim against trespassers. It is used to claim damages or possession of a property, or both. The form is used when a landlord has attempted to evict a trespasser from their property but has been unsuccessful.

The form is available from the UK government website and must be completed in full. It should be sent to the court with all relevant evidence, such as photographs and witness statements.

When completing the form, the landlord must provide details of the property, the trespasser, and the cause of the trespass. This includes the dates and times of the trespass, the landlord’s attempts to evict the trespasser, and any damage caused to the property.

The form also requires the landlord to specify the type of claim they are making. This can be either a claim for damages, possession of the property, or both. If the landlord is claiming damages, they must specify the amount they are claiming.

Once the form has been completed, it must be sent to the court within 14 days of the date of the trespass. If the form is not sent within this timeframe, the court may reject the claim.

In addition to the form, the landlord must also pay a court fee to cover the cost of processing the claim. The amount of the fee depends on the type of claim being made and the amount of damages being claimed.

The court fees for Form N121 vary depending on the type of claim being made and the amount of damages being claimed. For example, if the landlord is claiming damages of up to £300, the court fee is £25. For claims of more than £300, the court fee is 5% of the amount of damages being claimed. If the landlord is claiming possession of the property, the court fee is £355.
