Achim Walter Greiner

Lawyer | Certified Specialist for Tenancy and Residential Property Law | Notary

Achim Walter Greiner founded the law firm Greiner and Herrmann together with Hans Joachim Herrmann in 1993. Since appointment as a notary in 2000 and admission as a specialist lawyer for tenancy and residential property law in 2007, related activities have been the focus of his work.

Residential property problems are no longer a legal standard, but are associated with various pitfalls in detail. Residential tenancy law is characterized by an enormous wealth of statutory provisions as well as case law in the sense of social tenancy law, e.g. to protect the tenant from losing the apartment. For the landlord, this often results in drastic restrictions on the free availability of his property. In commercial tenancy law, faulty contractual arrangements often have serous financial disadvantages for the contracting parties.
As a notary, Achim Grainer provides impartial legal advice in matters of purchase, corporate, family and inheritance law as well as the fiscal evaluation of the will of the contracting parties to be notarized. In the case of more complicated transactions, cooperation with your tax advisor is a building block for optimal contract drafting.
Achim Grainer is voluntarily engaged in the association Haus und Grund in Stormarn e.V. and has been advising this association for more than 20 years.
