Key takeaways
  • Under New Brunswick's intestacy rules, an unmarried partner has no automatic share when there is no will.
  • A dependant's support claim may still be possible, but it must generally be brought within four months of the death.
  • Whether you qualify depends on the facts of your relationship, so get advice early.

Losing a partner is hard enough without learning that the law may treat you differently from a married spouse. If your common-law partner died without a will, you may be wondering whether you inherit the home, the savings, or anything at all.

The short answer in New Brunswick is that you generally do not inherit automatically. There is, however, a route that some partners can use, and it comes with a short deadline. This article explains both so you know what to look at first.

This article covers the law of New Brunswick.

What happens when there is no will

When someone dies without a will, the estate is divided under the Devolution of Estates Act. Its intestacy rules refer only to a widow or widower and do not mention common-law partners, so an unmarried partner has no intestate share.

Instead, the estate goes to the relatives the Act lists. A surviving spouse with no children takes everything, but where there is no spouse or issue the estate goes to the father and mother equally, then brothers and sisters, then nephews and nieces, then next of kin of equal degree. Because a common-law partner is not a spouse for this purpose, the estate can pass to relatives even if you lived with the deceased for many years.

There has been talk of reforming intestacy rules to include common-law partners, but we have not confirmed that any such change has been enacted. Check the current law with a lawyer before relying on it.

Why married spouses are treated differently

Married spouses have an extra tool. Under the Marital Property Act, a surviving spouse may apply to the Court to have marital property divided in equal shares as against the deceased's estate, generally within four months of death. That time can be extended if the spouse did not know of the death or was prevented by circumstances beyond their control.

That claim is available to married spouses only. The Act defines a spouse as a married person, so it does not help a common-law partner.

Married spouseCommon-law partner
Intestate shareYes, under the Devolution of Estates ActNo
Marital property division claimYes, within four months of deathNo
Dependant's support claimYes, as spousePossibly, if the Family Law Act test is met

The realistic route: a dependant's support claim

The Provision for Dependants Act lets a Court of King's Bench judge order maintenance and support out of the estate where a dependant's resources are insufficient, even against a will, and the judge may suspend administration of the estate. A dependant includes anyone who was a dependant of the deceased under the Family Law Act.

The Family Law Act applies the spousal support obligation to common-law partners in two situations:

If you fit one of these, you may be able to apply to the Court of King's Bench. Whether a particular partner qualifies is fact-specific, and a judge may refuse an order if the applicant's character or conduct disentitles them. An application is made by notice of application.

The four-month deadline

No application under the Provision for Dependants Act may be made later than four months after the death. The clock runs from the date of death, not from the date probate or letters of administration are granted, so waiting for the estate to be opened can use up your time.

A judge may allow a later application for any part of the estate that is still undistributed, if that is just. Do not count on this. It is an exception, and it only reaches property that has not yet been distributed.

Practical steps to take now

You may not control the estate. Where a person dies wholly intestate, administration may be granted to the spouse, next of kin, or the next of kin's spouse as the Court considers proper. That is usually a relative, not an unmarried partner.

One way to stay informed is to lodge a caveat against a grant, which can be filed with the Registrar or a probate office clerk. No proceedings may be taken on the application without notice to the caveator. A caveat generally stays in force six months unless withdrawn, vacated or a notice of intent to contest is filed.

Frequently asked questions

Does a common-law partner get the house if there is no will?

Not automatically. The intestacy rules do not give an unmarried partner a share, so the estate goes to the listed relatives. Ownership of the home may also depend on how title is held, which is worth confirming with a lawyer.

Can I still claim if the four months have passed?

A judge may allow a later application for any part of the estate still undistributed, if just. Once property has been distributed, that option is narrower, so act quickly and get advice.

Does the deadline start when probate is granted?

No. The four-month limit runs from the death, not from probate. The Marital Property Act deadline for married spouses is also four months from death.

Is it certain I qualify as a dependant?

No. A common-law partner must meet the Family Law Act test of three years of continuous cohabitation with substantial dependency, or a relationship of some permanence with a child born to you both. It is fact-specific, so a lawyer can assess your situation.
