Co-op have sent chq for £765 (claim was for £780 - they altered the claim dates - crafty). Anyway I had already issued court proceedings (in which I added interest and the £120 court fee). Co-op reacted too slowly and the court papers would have been issued around the same time as they paid £765 - so I want the other £15 and the interest and the court fees back. I have to let the courts know immediately that I have received some payment. How do I let the courts know that I have received part payment? Is a simple letter ok or is there a special form? Thanks for any help.
