How Do I Instruct You

You can instruct us by email or in writing. We prefer email as it is quicker and cheaper for us to administer.


For an initial discussion about your case please call us on 01904 567 970. We will guide you through what you need to do and how we can help.

Please have ready a brief description of what is in question and what can be taken as reference material. This is all we need to provide you with a quote. Scanned images are also helpful.

If the quote is acceptable you must then email or write to us to the effect that you are instructing us in your case. We cannot accept instructions on the telephone and for LSC work please send us confirmation of your prior authority. If original documents are not available please email us with good quality scanned images as pdf files. Remember to let us know what is in question.

Send any original documents to us by special delivery so that a record of continuity can be obtained. All documents are signed for and are returned to you by special delivery.
