Applying against a relative, adult child or housemate

Reviewed 19 October 2026 · Information for England and Wales

It's a common misunderstanding that non-molestation orders are only for abusive partners. The law reaches parents, grown-up children, brothers and sisters, in-laws, step-relatives and people you have shared a home with. The deciding question is whether you are "associated" with the person.

The eight ways to be "associated"

Section 62(3) of the Family Law Act 1996 says you are associated with someone if you:

  1. are or were married or in a civil partnership
  2. are or were cohabitants – living together as a couple
  3. live or lived in the same household, other than simply as employee, tenant, lodger or boarder
  4. are relatives
  5. agreed to marry or form a civil partnership, even if it was called off (within three years of it ending)
  6. have or had an intimate personal relationship of significant duration
  7. are both parents of a child, or both have parental responsibility for one
  8. are both parties to the same family proceedings

Who is a "relative"?

Section 63 gives a broad definition covering your own, or your spouse's or partner's:

  • parents and step-parents
  • children and step-children
  • grandparents and grandchildren
  • brothers and sisters
  • aunts, uncles, nieces and nephews
  • first cousins

Half-blood relatives and relatives by marriage or civil partnership are included, as are the relatives of a former spouse or partner, or of someone you lived with as a couple.

When the abuser is your adult child

Abuse of parents by grown-up children is more widespread than people think, and often very hard to talk about. A non-molestation order can stop an adult child using or threatening violence, harassing you or coming to your home. If they live with you and need to leave, an occupation order may also help – the court will consider their needs too, including where they would go.

Wider family, forced marriage and "honour"-based abuse

Abuse from in-laws or extended family, including forced marriage and so-called "honour"-based abuse, can be covered. If you fear being forced into marriage there is a dedicated Forced Marriage Protection Order. Contact the Forced Marriage Unit on 020 7008 0151, or 999 in an emergency.

Former housemates

People who shared a household are associated even if they weren't a couple or related – friends sharing a flat, for example. But someone who was only your lodger, tenant, boarder or employee isn't. The court looks at how you actually lived.

"Significant duration" relationships

This category covers partners who never moved in together. There is no fixed minimum; the court looks at the relationship as a whole. Several months of regular contact is often enough – a couple of dates usually isn't.

Not associated? Other options

You can't get a non-molestation order, but you still have routes to protection:

  • A harassment injunction under the Protection from Harassment Act 1997, from the County Court (normally with a court fee).
  • A Stalking Protection Order, applied for by the police.
  • Report to the police – harassment, stalking, threats and assault are all crimes, and a criminal court can make a restraining order.
  • A Domestic Abuse Protection Order, if you're "personally connected" and live in a DAPO area. See DAPO or non-molestation order.

Children applying

Under-16s can apply, but only with the court's permission. If you're worried about a child, contact the police, the council's children's services, or the NSPCC on 0808 800 5000.

How we help

Tell us on the form how you are connected to the person. If you're not sure whether you're associated, choose "Other / not sure" and explain – we'll check before drafting anything. Get started.

Can I apply against my own mother or father?

Yes. Parents are relatives, so you are associated and can apply if their behaviour justifies an order.

What about my ex's new partner?

Usually not through a non-molestation order, as you're not associated with them. A harassment injunction or a police report is more likely to be the route.

Let us draft your court papers – free
