Applying to Court for an Interim Contact Order is the easy part.
The form is a C100 form which is a form for all applications under section 8 of the Children Act (1989). "section 8" orders include - residence (sole and shared residence), contact order, prohibitive steps order, specific issue order.
If there has been a shared care parenting arrangement in operation for a reasonable amount of time (6 months or more) then I see no reason why your partner should not apply for a Shared Residence Order.

If your partner does not have Parental Responsibility (PR) then he will need to apply for this too on a C1 form. He will have PR if he was married to the ex or is named as father on the birth certificate and the birth was registered after Dec 1 2003.
The cost for the application is £175. You will need to file 4 copies of the forms to Court (one for you, one for the ex, one for the Court and one for CAFCASS).
It's a bit premature at first because there is some further information I would be grateful for;
- How old is the child
- What is the normal parenting schedule week-to-week (you said 50:50)
- What happens for holidays
- How long has the parenting schedule been in existence.
- How far away does the ex live
- Are the CSA involved at all. Does dad pay child maintenance and if so does he keep a record of it (i.e. cheque/standing order).
Re. the abusive calls texts - keep a log of these. Keep all texts, consider starting to record any telephone calls (or even better ignore them!).
Get along to your local family liaison officer at the police station and get this recorded. It is domestic abuse. At least get it logged and recorded.
Keep a diary of EVERYTHING that happens from now on. Start thinking about producing a chronology of events - because the ex will try and change the parenting schedule and bring out all sorts of nonsense.
Before making an application to Court you should consider Family Mediation - it's an essential step and the Courts will expect you to explore this first. Look up the local family mediation services and get the ball rolling on that first.
Get along to your local FNF branch and GET ADVICE.
You should consider joining FNF as there is a really good bulletin board full of advice and support.
Consider using a solicitor as a last resort - they are very expensive and usually mess things up! Hopefully there will be an available McKenzie friend via your local FNF branch.
