Dr. iur. Marko Oldenburger

Attorney, certified family law attorney, certified medical law attorney

European family law, inheritance law and medical law

artvocati supports clients with individual and dedicated legal advice and representation. Dr. iur. Marko Oldenburger, a certified family law and medical law attorney based in Hannover, has successfully advised and assisted clients for many years with his extensive expertise in both national and international legal matters.

The owner of the firm, Dr. Oldenburger has been an independent attorney since 1998. His law office was initially located at the seat of the Higher Regional Court in Celle. In 2010, the firm was relocated to the state capital Hannover. Since he was admitted to the bar in 1998 his main focuses have been medical law and entire area of family law and inheritance law. He has particular expertise, accumulated over a period of many years, in the area of doctors’ separations and divorces, at the intersection of medical and family law. For both of these areas, Dr. Oldenburger was granted the title of certified attorney due to his extensive theoretical knowledge and practical experience.

Divorce law for doctors

Doctors in private practice are in a special situation in a separation or divorce case, because company shares, including the monetary value of the practice, usually have to be included in the legal negotiations. Dr. iur. Marko Oldenburger supports, advises and represents his clients with his excellent knowledge of both perspectives – the legal form of medical practices and companies on the one hand and marital rights and obligations in the context of separation or divorce on the other.

In the area of marital property law, separation/divorce (which is often unexpected) involves issues relating to accrued gains. The preparation and implementation of asset negotiations are also increasingly significant. Furthermore, in the area of maintenance law, generally an area of conflict, doctors are positioned in such a way that as a rule instead of “ratio maintenance” a concrete amount of alimony and post-marital maintenance must be calculated. Dr. Marko Oldenburger, a certified medical law and family law attorney in Hannover, supports medical professionals with his detailed knowledge of specific maintenance calculations (particularly at the important intersection of medical and family law where doctors separate/divorce) both locally and across Germany.

Family law and inheritance law with European and international references

Dr. iur. Marko Oldenburger also supports his clients with special expert assessments in the area of European family law and inheritance law, i.e. in cases where, for example, marriages between spouses with different nationalities are concluded or fail. Thanks to his detailed knowledge of proceedings and disputes with a multinational character, Dr. Oldenburger can provide you with sound advice. He will competently represent your interests in court proceedings in Germany, including according to the separation/divorce laws of other countries (e.g. England, Ireland, Wales, Spain, Italy, Poland, Serbia, Croatia, as well as Canada and the USA etc.), as well as in cases involving international child abductions or maintenance arrangements. Both issues concerning the international competence of German courts, for example pursuant to the Brussels II Regulation, the EU Maintenance Regulation or the Hague Maintenance Protocol, and issues arising under the applicable substantive laws will be effectively clarified.

Family and inheritance law matters are an emotional process and every client handles this situation in their own way. I support my clients by dealing with their concerns objectively and arriving at the best practicable legal solution for them.

Medical law

Joining or leaving corporations of practising doctors (BAG) and their establishment are, alongside medical liability claims, the focal points of Dr. Oldenburger’s work in the area of medical law.
