I need a little legal advise, mean neighbor...?

my husband has been accepted into the police accademy here in california, it starts in july, and now our neighbor whom we have had probloms with since we lived here ( 1 and 1/2 years) is filing a restraining order against him, for false accusations. i need to know who do we go to to get the order lifted, and what kind of documentations do we need. he is saying we filed false claims against him with cps, (wich we did call them, because he was filming our son running around naked in our house), we called the sherrifs office first and they never came out to talk to him. and he is also saying we filed a false report with animal control even though we brought the animal control evidence that his dog was in fact in our yard many times, and we have witnesses. what can i do so my husband doesn't have to throw away his dreams of being a cop??
