^A non-molestation order is aimed at preventing your partner or ex-partner from using or threatening violence against you or your child, or intimidating, harassing or pestering you, in order to ensure the health, safety and well-being of yourself and your children.
An occupation order regulates who can live in the family home, and can also restrict your abuser from entering the surrounding area. If you do not feel safe continuing to live with your partner, or if you have left home because of violence, but want to return and exclude your abuser, you may want to apply for an occupation order.^
Under new legislation, a breach of a non-molestation order is now a criminal offence; however, you should still be able to take your abuser back to the civil court for breaking the order, if you prefer this.
If you already have an injunction, you may have a power of arrest attached, and you can also have powers of arrest attached to an occupation order. These powers come into effect if your abuser breaks the order
SS will be notified and you can ask SS for help and support keeping him away.
Please contact your family and tell them you need their support.
Please also call 0808 2000 247 - Women's Aid - to ask for their help too. Leave a message. They will get back to you.

Wishing you strength and courage. Hug your children. They won't be taken away from you. Stay strong.
