Testimonials
‘A strong and experienced group of partners and senior lawyers that will give clients the senior attention needed. Strong commercial sense and fair prices.’
‘The partners have a strong entrepreneurial approach to everything they do. They are highly committed and innovative.’
‘I think and feel that they have a human environment where employees are given a free space to be skilled professionally but are also flesh and blood people. All things being equal, this results in a different type of person who has increased knowledge, vision and energy to understand what is central and what may be less important in a case. Strong valuable attribute.’
‘Thomas Donatzky is outstanding. Serious, sympathetic and exceptionally large work capacity and ability to get to grips with a situation and get it resolved.’
‘High professional level, lawyers always available, including over the summer, a broadly composed team that could take care of different areas of expertise, a high degree of friendliness and hospitality.’
‘Our experience with competitors is not extensive. But what was important in our case was an approachability despite our lack of knowledge about business acquisitions and sales, and patience to repeatedly explain and elaborate for us. As well as understanding that other professional expertise than law was essential in specific areas for the preparation of a good agreement. The sale of our company was a success with few serious obstacles along the way. Donatzky & Partners successfully navigated the deal in a well-balanced manner.’

Real Estate
Donatzky & Partnere has the resources and capabilities to handle any real estate transaction on equal footing with other top-tier law firms in the field.
With strong market knowledge across Denmark—especially in the Greater Copenhagen area —we provide effective and commercial advice on potential opportunities of buying or leasing a property.
We advise on all aspects of real estate, including acquisitions and sales of properties and property companies, investment strategy, valuations, pricing, and negotiations.
Our expertise covers:
- Real estate transactions
- Project development
- Commercial lease law / landlord and tenant matters
- Owner-occupied apartments and cooperative housing associations
- Construction and development
- Planning and environmental law
We assist both private and commercial clients with contracts, project development, tenancy matters, corporate structuring, and compliance with legal and regulatory requirements.
We also advise landlords and tenants on commercial lease agreements, rent regulation, financing, restructuring, and the formation of owner and tenant associations.
In the construction space, we provide legal support for construction and consultancy agreements, project financing, insurance, environmental considerations, and liability issues.
Thanks to our strong local insight and legal expertise, we provide practical, commercial, and holistic advice—from initial assessment to final transaction.

We advise in all types of business transfers—from strategy and negotiations to due diligence and closing.
We assist with company formation and choice of corporate structure, mergers, demergers, capital changes, general meetings, and corporate registrations.
We also provide guidance on management liability, restructuring, and GDPR/data protection—both in day-to-day operations and in connection with transactions.
