Starting from arbitrary Hilbert spaces, we reduce the problem to verify entanglement of any bipartite quantum state to finite-dimensional subspaces. Entanglement can be fully characterized as a finite-dimensional property, even though in general the truncation of the Hilbert space may cause fake nonclassicality. A generalization for multipartite quantum states is also given.
