A person who believes that they are being bullied or who has been a victim of domestic violence or coercive controlling behaviour, can apply to court for a non-molestation order to prevent the other person coming within 100 m of them and an occupation order for the alleged perpetrator to move out of the house.
Here are the government webpages on exactly this subject. https://www.gov.uk/injunction-domestic-violence.
A range of people can apply to the court: spouses, cohabitants and ex-cohabitants, people living in the same household (but not employees), tenants, lodgers, boarders, and certain relatives such as parents grandparents, in-laws, brothers sisters, and engaged couples. So basically people who are in a close relationship either physically or family or living together whether that’s in a relationship or just the same house.
There doesn't actually have to be physical violence per se because there can be coercive behaviour for example as you will read in this excellent article:
If living arrangements are involved, it is very often impractical to live in the same house and it would very often be allied to an occupation order which defines or regulates the rights of occupation of property by the parties involved.
Many landlords will not change the name of the tenancy agreement for example without an Occupation Order.
It always helps if a report was made to the police recently because that is good evidence that this actually happened. The reason is that to report something to the police which hasn’t happened is a serious offence of wasting police time and/or attempting to pervert the course of justice which potentially carries a short jail sentence. So the civil court will take more notice if it has been reported to the police.
Having said that, the civil court will normally err on the side of caution and grant the order. However if the order is applied for based upon fabricated facts and that comes out in the wash, that is also perverting the course of justice and contempt of court and also potentially carries a jail sentence.
As there is usually some urgency with these kind of applications, it can be done on an emergency basis and there is the option on the form to as for an urgent hearing. An applicant can also attach a Certificate of Urgency (a letter with that heading) explaining why this should be in court on an emergency basis, usually within a day or so.
These applications are usually made “ex parte” which means that the other side doesn’t get notice until the order has actually been made.
The first they know about it is when they are served with a copy of the order.

The effect of the order is exactly the same as a restraining order. A restraining order is something applied for by the police/CPS through the magistrates court whereas a non-molestation order is through the family/civil court.
Section 1 of the Domestic Violence, Crime & Victims Act 2004 makes the breach of a non-molestation order a criminal offence. It’s serious stuff, and the non-molestation order carries a power of arrest as a result. It applies from the moment that the recipient of the order is served with it.
There will be an opportunity for them to present their case to the court in due course, after the initial order is made. But it effectively remains in place (normally for a year) unless they can prove to the court that it is not necessary.
