It is trivial in many states and jurisdictions to get a temporary order. One was obtained against David Lettermen just by a woman in a different state claiming he was sending her secret messages through the TV.
The final order is more difficult, but quite often (i.e. in divorce / custody court) the only goal was to evict them from the home and disrupt custody to get the upper hand in hearings, so temporary is all that's needed to do the job and then no need to actually defend the claim made 14+ days later when they're already homeless and with the baseline of out of the kid's life.
