How can I insist on no contact?

[crackcrackcrak]

I have a non mol currently against my very EA and sometimes violent ex partner. I knew I would need it post split.
We have 2 dc.
We have contact only through solicitors but even this is getting out of hand. Exp is doing everything he can to circumvent the non mol and get at me without actually physically doing so. I get reams of sol letters accusing me of everything under the sun. He has also now targeted my nursery as a method of arguing with me indirectly. He often approaches close friends of mine though they all refuse to discuss me with him.
He is not being threatening but very antagonistic. What can I do to make no contact mean no contact! Obviously I I ow I can't avoid divorce proceedings which are Ongoing. Someone suggested a handover book for contact which my sol has jumped on thinking it will solve loads - I don't and regret mentioning it - he will just use it to attack me.
Any ideas?

How old are dc? At least a contact book is there for all to see/read!

Under 3. The contact book is really bothering me

I would look at it as proof, or perhaps as evidence? And make sure he knows it too! Could he have a family members number in case of emergency? Someone to act as 'third' party?

We already have that - it's 3rd party hand overs for contact. I wouldn't invite him to contact my family - he will just harass them.
There is a contact order and I thought he might settle down after that but he's actually worse! Feel like he will never leave me alone or respect my privacy or stop constantly antagonising.
I would chat to him openly about parenting stuff if he could be adult and diplomatic about it but he has proved without doubt he cannot

I have a non mol out on my ex. He sometimes does silly little things to get round it. I report anything to the police most of the time it just gets noted down. They nicked him once. It was over something little. They done him for it.

You need to instruct your solicitor NOT to forward any letters to you unless they relate directly to the children/financial issues which need actioning (There are currently over 400 pages of 'crap' from my ex on file in my solicitors office)
You go back to the police and tell them that he is breaking the Non Mol - if you take the letters with you, you may be able to get him cautioned for harrassment. With regards your friends, they can also call the police. My solicitor wrote to Ex to specifically ask him not to contact a family member - he continued to harrass her and she rang the police who warned him that if he did it again, they would arrest him. They advised her to take a Non Mol out against him.

Thanks all
Sassy - that was v helpful I shall instruct my sol as you have done - I think that might help a lot.
The non mol was through sol only do unsure if I can go to the police.
