When A Common Law Spouse Dies Without a Will- Death of Spouse

Common-law spouses are not treated the same as married spouses under the law and do not automatically have the same property rights. In Ontario, if a common-law spouse dies intestate (dying without a will), the surviving spouse will not inherit any part of the estate. They are completely omitted. However, depending on the facts and circumstances, a surviving common-law spouse can file a claim against the estate in two ways: filing a dependency claim or filing a claim for unjust enrichment.

Dependency Claim

If a common-law spouse was dependent on the deceased and the deceased did not adequately provide for them in a will, the common law spouse could be entitled to file a dependency claim. This would be done by filing an Application against the estate in court. A judge can award a lump sum, a periodic payment, or a transfer of a specific asset to a surviving common-law spouse.

The Succession Law Reform Act (Ontario) broadly defines “spouse” and includes those couples who cohabited for at least three years or couples who are in a relationship with some permanence and have a child together. Section 57 of the SLRA includes a spouse in the definition of “dependant”. Section 62(1) of the SLRA lists many factors that the court should consider in determining the amount and duration of support, including the moral obligations of the deceased. A calculation of dependency must be supported with an Affidavit and documentation by the surviving spouse.

While this may be a successful way for your surviving common-law spouse to obtain adequate support, it is a long and costly process both financially and emotionally. Also, be aware that this type of Application must be filed within six months of the Certificate of Appointment of an Estate Trustee / executor being granted.

Unjust Enrichment Claim

Unjust enrichment is an equitable principle that one person should not receive a financial gain at the other’s expense. Examples are when one spouse takes care of the home or provides services without compensation from the other spouse. A common-law spouse can make a claim against the estate on this basis. There must be some kind of valuable gain to the deceased, at the expense of the survivor, without a legal reason for that gain. Meaning, there is no contract or legal obligation for that spouse to provide a gain to the spouse that died.

This unjust enrichment claim can be remedied by the court in two ways:

  1. by using a constructive trust
  2. by a quantum meruit award

A constructive trust awards property, equal to the surviving spouse’s contribution. Quantum meruit is a monetary award based on the promise of a future award from the spouse who died. Courts generally prefer this relief over a constructive trust if it is available. Although the Supreme Court of Canada case law supports these awards for unjust enrichment, it is a long and costly road to travel. It should also be noted that the Court of Appeal of Ontario recently ruled that claims for unjust enrichment for real property falls under the 10 year limitations period s. 4 of the Real Property Limitations Act.

    How can we change this? How can we get the gov’t to recognize common-law partners as “legal” spouses without a marriage certificate? In the 21st century, there are probably more common-law couples than married couples. Many people do not believe in marriage, or are not religious, or do not feel they need to pay for a piece of paper to prove their bond or love. It’s a cash grab by the government. My common-law and I have been together for over 16 years now and have 3 children. I have legally taken his last name. We don’t feel the need to get a piece of paper for the government (only) to see use as husband and wife because, to each other, we ARE husband and wife. We take care of each other and if, after so many years, one of us should pass and the government says “No! everything you two built together in your relationship is no longer yours unless you can PROVE it!!” is extremely unfair and unjust to the person who just spent the majority of their life with that person. I think, when a couple of co-habitates for 10 years or more, the government should recognize them as legally “married”. I actually think they should do away with “legal” marriages, but again it’s a cash grab all the way around so I know it will never go anywhere.
    Who can I contact to petition to have this changed?

      Hi Julie, I hear you!

      You need the legislature to change the definition of “Spouse” under the Succession Law Reform Act.
      That would resolve the issue.

      Hello and thank you for your question.
      Your own personal belongings or your children’s, are yours to keep.
      Only things that were his, are part of the estate.
      While he may not have included you in the Will, it is possible that you may still have a legal claim against his estate.
      You should seek legal advice as soon as possible to ensure that you know what your possible entitlements are.
      Please email me directly if you would like to arrange a consultation.

    If a common-law spouse is palliative and has no will and may not be deemed to have capacity, could the POA who has fore-knowledge of their wishes draw up a will for her/him? Could it stand up in Court?

      Hello. Unfortunately, no. Only the testator can write their own will.

      Hello and thank you for your question.
      Please let me know with what rules you are referring to?
      Tenants in common versus joint with survivorship are very different.
      The best course of action is to have a consultation with an estates lawyer who can review all your questions with you and provide you with the best recommendations.
      You can email me at amy@hummingbirdlaw.com if you would like to set something up.

    My parents passed years ago leaving the family house and cottage to my siblings and I. My brother passed late 2019, and his common law (on and off for 10 years) believes she has a claim to the family property. Is this true? He passed without a will, and they were both married (just not to each other). How can we protect the family assets? She collected his life insurance, his CPP and his pension and now wants more. Please advise.

    My daughter passed away. She was living common law with a man who was legally separated but not divorced from his first wife. There was no will and no beneficiary of her insurance. As her Mother do I inherit as there are no children.

      Hello Mary, please accept our condolences.
      If there is no named beneficiary, then the insurance will be made payable to her estate.
      If you are the next of kin, then under the Succession Law Reform Act, you will be the beneficiary.
      Common-law spouses have no automatic property rights.
