It is well known that for all recursively enumerable sets $X_1, X_2$ there are disjoint recursively enumerable sets $Y_1, Y_2$ such that $Y_1 \subseteq X_1, Y_2 \subseteq X_2$ and $Y_1 \cup Y_2 = X_1 \cup X_2$. Alistair Lachlan called distributive lattices satisfying this property separated. He proved that the first-order theory of finite separated distributive lattices is decidable. We prove here that the first-order theory of all separated distributive lattices is undecidable.
