According to German law an heir can declare the renouncement of succession to the competent German Probate Court within six weeks - if the heirs are outside of Germany within six months - after receiving knowledge about the inheritance.
If you cannot personally declare the renouncement at the competent German Probate Court, the certification of your signature can also be carried out by the legalisation desk of the Embassy. After certification of your signature you will have to send the renouncement form to the German court.
A draft renouncement declaration is available for download below.
Attention! The draft declaration is a template only; it must be amended/changed by the person renouncing according to the individual case as necessary. The German Embassy explicitly reminds you that the draft is provided as a non-binding service without accepting any liability. Please refer to a member of the legal profession should you require advice concerning your individual case.
Please get in touch with the legalisation desk before coming to the Embassy.
