Legal Question in International Law in Germany

Re: International validity of last will

In principle, a will can be drawn up anywhere; the validity is not depending on the location where it was made, but merely subject to the relevant provisions as to the form of a will (cf. sections 2231, 2232, 2247 German Civil Code).

With regard to the content of the will, it might, however, still be sensible to draw up a new one in front of a German notary, in particular if the original one includes references to US state or federal legal provisions, which might be difficult to understand for a German executor. However, please note that this is not a question of validity but rather practicability.
