Hi, this is Jim, thank you very much for the question - I will resolve this for you today.
If you are in England & Wales, and the Defendant is in Scotland, you need forms N1 and N510 (the latter you need to go to page 2 and tick the first tick box, then sign the form). You need 3 copies of the N1 / N510 and post to County Court Money Claims Centre, PO Box 527, Salford, M5 0BY. The court then issues the claim and returned the forms to you to serve - you then use form N215 (attached) to serve the pleadings.
For a claim of £7500 the court issue fee is £455. If you pay by cheque, it is made payable to HMCTS. If no cheque is enclosed the court will ring you to take payment over the phone. The £455 is added to your £7500. You can also claim interest of 8% daily from when you were first owed the money to when you issue the claim, so that is £1.64 per day. That is also added to the claim.
Once you obtain a court judgment for the full sum owed, the defendant has 14 days to pay - if they do not pay you can register the judgment with the Scottish courts for enforcement.
For a cease and desist letter, go to the law depot site and type in the search box "cease and desist", you want the general letter, which can be tailored and downloaded. The site is here:
I hope this helps - please feel free to ask me anything else. If you could please click 5 stars at the top of the screen I would be grateful.
Have a good evening.
