Simpson Thacher & Bartlett LLP is authorized and regulated by the Solicitors Regulation Authority (SRA No. 380782).

Simpson Thacher & Bartlett LLP is registered as a limited liability partnership under the laws of the State of New York. The personal liability of our partners is limited to the extent provided in such laws.   

Information on the regulations of The Solicitors Regulation Authority can be found in the SRA code of Conduct 2011 (“the Code”) on its site at https://www.sra.org.uk/solicitors/handbook/code/. The Code and various other legislative instruments referenced in the Code govern the conduct of the Firm.

We are confident that we provide our clients with a high quality service in all respects. However, in the unlikely event that a client has any concerns with our services, they may take the matter up with the partner supervising the matter in the first instance. If the partner is unable to resolve a client’s concerns, a client  may then take up the matter with the London Office Managing Partner. The Firm has a written complaints procedure that is available upon request.

The Code provides for recourse to a non-judicial means of dispute settlement through the Legal Ombudsman (“the LeO”). The LeO can help if we are unable to resolve a client complaint ourselves. They will look at a complaint independently and it will not affect how we handle a complaint.

Before accepting a complaint for investigation, the Legal Ombudsman will check that a client has tried to resolve the complaint with us first. If so, then a client must take their complaint to the Legal Ombudsman:

  • Within six months of receiving our final response to a complaint, and
  • No more than six years from the date of act/omission; or
  • No more than three years from when a client should reasonably have known there was cause for complaint.

For more information about the Legal Ombudsman, please contact them at:

A client can also raise concerns with the Solicitors Regulation Authority.
