What is the difference between a notary and a solicitor?
The notary is an impartial holder of a public office. He certifies contracts and declarations in a legally secure manner for all parties involved and provides neutral advice. A solicitor, on the other hand, represents the interests of their client alone. Prof. Dr. Frank Martin performs both functions – but always separately and with clear role distinction.
What is a specialist solicitor and what advantage does this offer me?
The title "Fachanwalt" (Specialist Lawyer) is only awarded by the Bar Association after proof of special theoretical knowledge and extensive practical experience in the respective area of law. Prof. Dr. Frank Martin is a Specialist Lawyer for Inheritance Law, Employment Law and Family Law – so you receive a threefold proven specialisation.
What does an initial consultation cost?
Fees for legal services are governed by the Rechtsanwaltsvergütungsgesetz (RVG) or an individual agreement. Notarial fees are set by statute in the Gerichts- und Notarkostengesetz (GNotKG) and are therefore uniform throughout the country. We will inform you transparently in advance of the costs you can expect.
At which locations can I attend an appointment?
You can reach us at our main office in Limburg an der Lahn (Parkstraße 33) as well as at our branch office in Montabaur (Bahnallee 11–13). You can arrange appointments by phone on 06431 - 2 88 88 88 or via our contact form.
How do I prepare for a notarial appointment?
For most certifications, we require in advance the personal details of all parties involved as well as the relevant documents (for example, land register data for a property purchase). Once we have received your information, we will prepare a draft for you to review at your leisure. At the appointment itself, the deed will be read out in full and explained.
Let's talk about your matter.
A brief conversation often brings clarity. Arrange an appointment – we will take the time for you.
