We have successfully gained a Possession Order following serving a Section 21 notice, and are now in the process of transferring to the High Court to evict the tenant (due to delays enforcing through the County Court). We also now wish to claim for lost rent, and have been advised to complete Form N1. I am just looking for a little help in completing the form, as I'm not sure what information / evidence they need. First of all, what do I complete in the box at the top 'Fee Account Number'? Then in 'Brief details of claim' do I just put something like: 'The claimant wishes to claim for lost rent, for the rental property outlined above, which is payable by the defendant on the 2nd day of each month at a rate of £900 per month. The defendant has not paid rent since June 2014, so is currently 4 months in arrears, owing a total of £3,600'. Court fees have changed in recent months, and I am finding mixed information on what would be the court fee to enclose with this application. Do I need to complete anything in the section entitled 'Particulars of Claim'? Do I need to reference the fact that a Possession Order has been issued and that he has already been ordered to give up the premises and pay costs, or is this not relevant? Does any evidence need to be included, such as a letter from our Letting Agent confirming that he is in rent arrears? Thank you for your help.
