You need to urgently seek help. We can guide you through the process to make an application to the Court for your protection.
Court Orders can be made which are legally binding, these can be made without the other person being given notice until after the Court Order has been made and served on the other person.
These orders are called Non Molestation Orders and these prohibit the other person from threatening violence, harassing, pestering or being abusive towards you.
The Court has the power to make another order which defines and limits the occupation of your home even if the other person is a joint owner of the home.
Please take legal advice immediately to go through your options if you are a victim of domestic violence or harassment.
