  We provide a natural characterisation for the sets of elliptic and hyperbolic
hyperplanes of the parabolic quadric Q(2n,q) when q is even. This
characterisation is based on the number of elements of these sets through
points and codimension 2 spaces and generalises [S. Barwick, A. Hui, and W-A.
Jackson. Characterising elliptic solids of Q(4,q), q even. Discrete Math., 343
(6) (2020), 111857] and [S. Barwick, A. Hui, W-A. Jackson, and J. Schillewaert.
