Bayern Info, a periodical for members of the Bavarian section of the BDÜ, supplies information from issue 12/2003 of AWI (Außenwirtschaftsinformationen der Industrie- und Handelskammer für München und Oberbayern). This is apparently not online, but can be obtained by email.
The AWI points out that on some websites of German embassies, there are lists of lawyers and legal information sheets. At the German Embassy in the UK, for example, there is a list of German law firms of Rechtsanwälte in London and ‘Britische Anwaltskanzleien in London, mit denen in deutscher Sprache korrespondiert werden kann /
English firms of solicitors in London with which correspondence can be
conducted in German’. There is also a memorandum (in German) on obtaining legal advice and taking legal action in England, Wales, and Northern Ireland.
