Why Where You Live Matters for Estates Law

The Importance of Where You Are Domiciled

When someone dies, one of the first questions that may need to be answered is: Where was this person legally considered to live? In legal terms, this is called a person's domicile.

 

A domicile is more than just where someone happens to be living. It is the place that is considered their true, permanent home.  It’s common for a person to own homes in different places, spend time in several provinces or countries, and even have residences in more than one jurisdiction. However, at any given time, they can have only one domicile.

 

Many estate administrators assume a person's domicile is obvious and move on without giving it much thought. However, in today's world, people often divide their time between multiple locations, making the issue more complicated than it once was. Determining a person's domicile at the time of death can be very important. For example, it may determine:

 

  • Whether a will is legally valid
  • Which province's or country's estate laws apply
  • How assets are distributed if the person died without a will

 

Ontario's Succession Law Reform Act uses the concept of domicile in several situations, but it does not define the term. As a result, courts rely on legal principles that have developed over time.

 

Types of Domicile

 

There are two main types of domicile that arise in estate matters:

 

1.   Domicile of Origin. Every person receives a domicile of origin at birth. This is usually based on their parents' domicile.

 

2.   Domicile of Choice. Later in life, a person may establish a domicile of choice by making a new place their permanent home. 

 

How Does Someone Change Their Domicile?

 

The law assumes that a person's domicile of origin continues unless there is clear evidence that it has been replaced. To establish a new domicile of choice, two things must be shown: (1) Actually living in the location, and (2) A settled and fixed intention to make the location their permanent home - see Taylor v. Taylor, 1929 CanLII 65 (SCC).

 

The first requirement is usually straightforward. The second is often much harder to prove. Courts look at the person's overall circumstances to determine whether they genuinely intended to settle permanently in the new location. No single factor decides the issue. Evidence may include:

 

  • Statements the person made about where they considered home;
  • How long they lived in the new location;
  • Whether they kept or sold property in their former home jurisdiction;
  • Whether they bought or rented a residence in the new location;
  • Their immigration or residency status;
  • The reasons they moved.

 

Someone who relocates for a temporary work assignment may not necessarily have changed their domicile. Or moving a loved one to a care facility in a different county or province could be a move dictated by circumstance. What if there is an intention to return? Compare those situations to someone who moves, establishes connections to the new community and their stay in the new location is indefinite with no plans to leave – they may have acquired a new domicile even where they continue to own a property in the place they just left. Maintaining ties to a former domicile does not automatically prevent a change of domicile.

 

Can a Domicile Be Abandoned?

 

Yes. A person can abandon a domicile of choice, but changing their mind is not enough. They must actually leave the jurisdiction where that domicile exists. If a domicile of choice is abandoned and no new domicile of choice has been established, the person's original domicile generally comes back into effect.

 

Why Does This Matter?

 

For estate planners, understanding a client's domicile can be important when preparing wills that involve assets in multiple provinces or countries. For estate trustees and lawyers handling estates, determining domicile may be essential to ensuring the correct laws are applied and that the estate is administered properly. As people increasingly live, work, retire, and own property in multiple jurisdictions, questions about domicile are becoming more common—and more important—in estate administration.

In Ontario, ODSP recipients are generally not permitted to hold more than $40,000 in non-exempt assets without risking their benefit qualification. As a result, receiving an inheritance—especially an unexpected one—can be stressful and confusing. Many recipients are left wondering whether the inheritance will reduce or interrupt their ODSP support. When families don’t know whether their intended-beneficiary collects ODSP or not, it can lead to the preparation of a Will that includes no planning to structure the gift properly-to protect the recipient's qualification for ODSP benefits. When that happens, the recipient (or, if they are incapable, their legally appointed representative) must consider whether there are ways to protect the intended beneficiary’s qualification. The ODSP $40,000 asset limit applies to non-exempt property and funds. However, certain exempt assets are not counted when determining ODSP eligibility. If an inheritance is not planned properly, a recipient who wants to remain eligible can consider whether enough of the inheritance can be transferred into exempt assets. This would mean that their non-exempt total stays within the allowable $40,000 limit. Examples of exempt assets under ODSP include: An interest in a principal residence One motor vehicle Funds held in a Registered Disability Savings Plan (RDSP) A trust created by the ODSP recipient using inherited funds, provided the trust capital does not exceed $100,000 A pre-paid funeral Household goods and furnishings required for the reasonable enjoyment of a home There are a number of planning tools available to skillful Wills practitioners to assist in protecting a beneficiary’s entitlement to ODSP - a prime example is a Henson Trust. If you are preparing your Will and you have a family member collecting ODSP benefits, getting good advice early is crucial. - Ian Keay

Ontario’s Will validation rules are meant to prevent unfair outcomes where a person clearly intended a document to be their final Will, but the signing formalities weren’t perfect. However, there are limits — especially when the only “Will” is an unsigned draft that exists as a digital document only. A recent Ontario case, Madhani v. Fast, 2025 ONSC 4100, is a reminder that an unsigned electronic draft generally cannot be validated under Ontario law. The common scenario: lawyer takes instructions to draft a Will for Client lawyer prepares draft Will a signing appointment is booked the client dies before the Will is signed Will was not printed out - it exists in digital form only In Madhani , the draft Will was never printed and never executed. The draft existed only as an electronic file. Can the Court “validate” the draft anyway? Ontario’s validating provision is found at Section 21.1 of the Succession Law Reform Act (“ SLRA ”). Section 21.1 allows the Court to validate a document that does not comply with execution formalities provided it reflects the deceased’s testamentary intentions. In Madhani , the Court held Section 21.1 cannot be used to validate a Will that exists only in electronic form. Why not? Another piece of Ontario legislation, the Electronic Commerce Act, 2000 (“ ECA ”) explicitly limits the Court’s validating power. Section 31 of the ECA excludes Wills from electronic recognition. Section 21.1(2) of the SLRA explicitly makes Will validation subject to the exclusion under Section 31 of the ECA. In short: Ontario law still requires a physical testamentary document for validation to even be possible. Testamentary intention still matters Nevermind the “electronic draft” problem, which is significant on its own. There must also be evidence before the Court that supports that the digital draft was a valid reflection of the deceased Client’s fixed and final intention. Did the Client read the final draft? Did the Client sign the final draft? What evidence can be produced that shows what was drafted is an accurate reflection of the Client's "fixed and final intention"? Ontario courts often use the “deliberate, fixed and final intention” test drawn from George v. Daily, 1997 CanLII 17825 (MB CA). In Madhani , the draft Will was to be reviewed and confirmed at the signing meeting — only the signing meeting never happened – which means no evidence could be produced to decide whether the draft Will reflected the deceased Client’s fixed and final intention. The Court was not reasonably satisfied in Madhani . How this differs from other validation cases Ontario courts have validated Wills with execution defects where the document was physical and clearly authentic, for example: Cruz v. Public Guardian and Trustee , 2023 ONSC 3629 Vojska v. Ostrowski , 2023 ONSC 3894 But those cases involved paper documents that were physically present and clearly connected to the deceased’s fixed and final intention. Practical takeaways The Madhani case is a caution for both lawyers and families: print important drafts (especially when a signing meeting is imminent) try to obtain direct confirmation from the client (not only through intermediaries) digital drafts on devices may not be legally usable as Wills in Ontario Bottom line Madhani confirms that Ontario’s Will validation paradigm under Section 21.1 SLRA is helpful — but it is not a workaround for electronic-only drafts. Until legislation changes, a Will must exist in physical form before Ontario’s courts can consider validating the unsigned draft under SLRA s. 21.1.
