2.    Collection and storage of personal data, purposes of processing and legal principles

Martini · Mogg · Vogt · Lawyers · Public Auditors · Tax Consultants is a partnership firm with limited professional liability. Its corporate purpose is to provide comprehensive judicial and extrajudicial representation and legal guidance to private persons and companies both in Germany and abroad, including public auditing (a so-called “full-service” legal firm). MMV takes the protection of personal data particularly seriously.

If you engage our services, we will use our client questionnaire to collect from you the data required to offer advice and to assert and defend your rights within the scope of the assignment. This especially includes personal data such as surname, first name, postal address, telephone number, fax number and a valid e-mail address.

The processing of client data may also lead to the processing of personal data of other subjects. This may, for example, occur if you notify us of the name and address of your respondent.

On an individual case basis, we process personal data from publicly accessible sources, such as the Internet and telephone directories (e.g. address data). We may also use registers (including the Trade Registry and Registry of Residents) and public announcements. Further to this, we may avail ourselves of the services of external parties to obtain information (e.g. creditworthiness checks).

Data is processed for the purpose of the establishment, proper execution (appropriate legal advice and representation, including in official and legal proceedings), termination and invoicing of the assignment relationship (including the settlement of any liability claims and the enforcement of any claims that may have been asserted against you).

Processing is thus necessary for the performance of a contract to which the data subject is party or in order to take steps at the request of the data subject prior to entering into a contract (Article 6 Paragraph 1 b) GDPR). In the absence of provision of data on your part, establishment and processing of the assignment would not be possible and you would not be identifiable as a client for us.

Additional legal principles for processing are as follows:

  • you have given consent to the processing of your personal data for one or more specific purposes (Article 6 Paragraph 1 a) GDPR, processing procedures for which MMV obtains consent for a certain purpose);
  • processing is necessary for compliance with a legal obligation to which MMV is subject in its capacity as the data controller (Article 6 Paragraph 1 a) GDPR, e.g. for the fulfilment of tax duties);
  • Article 6 Paragraph 1 f) GDPR: processing is necessary for the purposes of the legitimate interests pursued by MMV or by a third party, except where such interests are overridden by your interests or fundamental rights and freedoms. Such a legitimate interest may, for example, exist in cases where you are a client of MMV or where direct advertising is used (including the sending of invitations to attend events at the firm).

Automated individual decision-making does not take place.

3.    Recipients or categories of recipients of the personal data to the extent required for managing the assignment relationship

  • Public bodies insofar as overriding legal provisions apply and then always within the scope of professional duties to maintain confidentiality.
  • Internal departments insofar as such departments require personal data for proper fulfilment of their tasks.
  • Service providers and processors (Article 28 GDPR) who are engaged to ensure the proper transacting of business.
  • External bodies for the purpose of proper fulfilment of the purposes stated above, including partner firms of the GGI (Geneva Group International AG) Network where required whilst maintaining compliance with legal provisions governing cross-border relations.
  • Banks, social insurance providers, tax offices, legal insurance providers, other insurers as necessary.
  • Respondents and their representatives (in particular lawyers), courts and other public authorities for the purpose of correspondence and in order to assert and defend your rights. Third parties may use data passed on for the stated purposes only.
  • In the event that the assignment relationship between you and us leads to a legal dispute, data necessary for the appropriate pursuit of legal claims (assertion and defence of rights) may be passed onto legal representatives or to the relevant courts and government authorities.

The above is without prejudice to attorney-client privilege.

The service providers engaged by MMV include cleaning companies and suppliers of beverages and office materials. No such service providers receive primary access to data.

Your personal data is processed by staff working inside the firm’s premises, at branch offices or at home-based workstations where such employment arrangements apply. The above are internal departments and units which participate in the execution of the respective business process. MMV also engages the services of freelancers, academic research staff, interns and trainee lawyers.

4.    Intended transmission of data to third countries or to international organisations

Individual assignments may involve transmissions of data to third countries and/or to international organisations (e.g. the World Intellectual Property Organisation, WIPO).

To the extent that transmission of data to third countries and/or to international organisations is necessary for fulfilment of the assignment, such transmission only takes place in accordance with statutory provisions relating to permissibility. A declaration of consent will be obtained from you on an individual case basis.

MMV cooperates with other external firms and is also a member of the GGI Geneva Group International AG, Schaffhauserstrasse 550, P.O. Box 286, 8052 Zurich, Switzerland. GGI is a worldwide alliance of established and experienced bookkeeping firms, consultancy companies and legal practices. Within the scope of these cooperation arrangements, data transfer to other countries within and outside Europe may occur on an individual case basis if MMV works in conjunction with foreign (partner) firms in the interests of fulfilling your assignment. This process takes place in accordance with Article 44 GDPR, and additional consent will be obtained from you if necessary. A list of the partner firms of GGI may be found at

5.    Further information

a) Duration of storage

Numerous duties of retention and retention deadlines have been enacted in legislation, and these include provisions which relate to the legal consultancy professions/lawyers. Duties of retention also exist under tax and commercial law. Relevant data is routinely deleted once these deadlines have expired.

Data not affected by these provisions is deleted once the stated purposes no longer apply.

Data may be retained for a longer period for possible reasons of liability or if you have consented to extended storage.

In the event that the statutory prerequisites apply, restriction of processing will take place instead of deletion.

b) Rights

You have the right to require confirmation from MMV as to whether personal data concerning you is being processed. If this is the case, you have a right to obtain access to this personal data and to be provided with information within the scope of the statutory stipulations. For this purpose, you may in particular contact us by e-mail at datenschutz(at) or address any enquiries to the data protection officer at MMV, the lawyer Mr. Thomas Haschert.

Any consent given to MMV may be withdrawn with future effect at any time. Withdrawal of consent is without prejudice to the lawfulness of the processing that has taken place on the basis of consent until such time this consent was withdrawn.

If the legal prerequisites apply, you also have the right to object to data processing (to the extent that your data is being processed on the basis of legitimate interests pursuant to Article 6 Paragraph 1 f) GDPR) and further have a right to erasure, rectification and restriction of processing of data concerning you and the right of data portability. The right of the client to data portability means personal data concerning you which you have provided to MMV must be received in a structured, commonly used and machine-readable format and that you have the right to transmit such data to another controller without hindrance from MMV.

Where personal data is processed for the purpose of direct marketing, you have the right to object at any time to the processing of personal data concerning you for such marketing. Personal data will then no longer be processed for such purposes.

The above rights may be asserted against MMV in any appropriate manner, in particular by post or e-mail. You may use the contact details included in the Legal Notice for this purpose or send an e-mail to
