In Brussels we practise through a partnership known as Slaughter and May, whose principal place of business is at One Bunhill Row, London EC1Y 8YY. The partnership is authorised and regulated by the Solicitors Regulation Authority.

All our resident partners and senior counsel in the Brussels office are admitted to practice as lawyers in Belgium under the professional title “advocaat” or “avocat” and are registered on the Tableau (Brussels Bar A List); they are also solicitors of England and Wales, and as such are also regulated by the Solicitors Regulation Authority. In addition, most of our other practicing lawyers established in the Brussels office are registered on the Brussels Bar A List, B List or EU List with either the Nederlandse Orde van Advocaten te Brussel ( "NOAB") or the Ordre français des avocats du barreau de Bruxelles (“OFAB”). 

Copies of the Orde van Vlaamse Balies (Order of Flemish Bars) and the NOAB rules of professional conduct are both available on the NOAB website, The rules of professional ethics applicable to members of the OFAB are available on its website,

A copy of the SRA Standards and Regulations is available on the Solicitors Regulation Authority's website, This includes the SRA Overseas Principles, which embody the key ethical requirements on firms and individuals who are involved in the provision of legal services outside England and Wales.

Client complaints procedure

At all times, we aim to provide our clients with a professional service of the highest quality.

Any client who is unhappy with any aspect of our service is entitled to complain. We treat all complaints seriously and are committed to investigating them promptly, fairly and free of charge.

If you have any complaint, including a complaint about your bill, you should raise it in the first instance with your relationship partner or the partner responsible for the relevant matter. If that is felt to be inappropriate, or if you feel that the response of the relationship partner or the partner responsible for the matter is inadequate, you can write to Julia Adams, our General Counsel, at One Bunhill Row, London EC1Y 8YY or by using the [email protected] email address.

We expect to resolve any problem to your satisfaction.

You may also be able to ask the Legal Ombudsman (“LeO”) to help you to resolve your complaint. Before accepting a complaint for investigation, LeO will check that you have tried to resolve your complaint with us first. If you have, then you must take your complaint to LeO:

  • within six months of receiving a final response to your complaint; and
  • no more than one year from the date of act/omission; or
  • no more than one year from when you should reasonably have known there was cause for complaint.

You can contact LeO by telephone on 0300 555 0333, (and if you are based outside the UK you can telephone on +44 121 245 3050); by email at [email protected]; or by post at Legal Ombudsman, PO Box 6806, Wolverhampton, WV1 9WJ.

LeO will only consider your complaint if, at the time you raised your complaint with Slaughter and May, you were:

  • an individual;
  • a micro-enterprise;
  • a charity that had an annual income net of tax of less than £1,000,000 (one million pounds sterling);
  • a club, association or organisation whose affairs are managed by its members, a committee or a committee of its members that had an annual income of less than £1,000,000 (one million pounds sterling); or
  • a trustee of a trust that had an asset value of less than £1,000,000 (one million pounds sterling).

LeO may also consider complaints made by a personal representative or beneficiary of the estate of an individual who raised a complaint with us, but had not referred it to the LeO, before they died.

If your complaint concerns acts or omissions outside England and Wales, LeO may dismiss your complaint if the circumstances do not have sufficient connection with England and Wales.

If your complaint relates to your bill, you may also be able to apply to court for an assessment of the bill under Part III of the Solicitors Act 1974.

If you do not wish to submit your complaint directly to us, as set out above, you may be able to submit your complaint via the European Commission's ODR platform.

Other complaints

If you are not a client but you nevertheless have a complaint in relation to our provision of legal services, please raise the matter with Julia Adams, our General Counsel. You can do this by writing to her at One Bunhill Row, London EC1Y 8YY or by using the [email protected] email address.

We will deal with any such complaint promptly, fairly and free of charge.

Client account and interest policy

As a general rule, the Brussels office does not hold money on behalf of clients. In the event that any client were to ask that money be held on their behalf, this would be held in a general client account at National Westminster Bank plc in London, on the basis explained in respect of the London office.
