Ditto Legal...do you have order in place now?
Ditto GrandmaB....police will not assist,even if order does state 1,3rd wkds...police have no clue if you 2 verbally agreeded to switch,etc...
If you have order,
Spend the $, send certified letter stating intent to use visit on _ date, from _ time to _ time. Be sure to include in letter body restatement of what your order says & fact time is your scheduled time. Gives you head start should visit be denied...request any reply to be written. Even if cp calls, says no visit...show up whereever u supposed to get child...daycare,school,cp's...especially if cp's home.....have a witness with you if possible, better if not spouse/partner. Get documentation from whereever that u showed up, have your cert.letter & order...and that child not available. If p/u at cp's...go to door w/ witness, express desire to pick up, if no...just leave, do not fight. Document facts. Continue to do same as long as issues/problems may be encountered....need to prove pattern w/ more than just your word/cp's word.
Court can be expensive, personal choice but, u can file a motion,represent self...only costs court fees & motion...if this is the only issue
One time or wait for a few....well who suffers here...child & NCP...not to mention that once you (ncp) allow cp to interfere with visits, you reinforce cp's assumed power to delegate visitation. If onetime, chances are will happen again. Letter from lawyer or NCP stating reprecussions or intent to prosecute cp if visit withheld may do trick, worth try. 1 time, 1 time too many,just as 1 support payment missed...seems quite unforgivable. I would nip in bud 1st time. If file order (visit is denied) talk to clerk or lawyer....there are ways to get case in court within week or 2 when issue has time factor.....I have gotten in in 2 days before, infront of diff judge due to time...Good Luck
