About half of Canadians die without a valid will, the country is in the middle of a roughly one trillion dollar wealth transfer, and lawyers report estate litigation climbing year after year. Together those facts make inheritance disputes one of the most predictable, and most preventable, family crises in Canada.
This page gathers the most important data on inheritance and estate disputes in Canada: how common they are, what causes them, how much they cost, and how a clear, valid will heads them off. Each figure links to a source listed at the bottom of the page. Updated June 2026.
How common are estate disputes?
Canada does not publish a single national count of contested estates, so the picture is built from court frameworks, surveys, and litigation practice. The signals all point the same way: disputes are common and rising.
1. Around 326,571 Canadians died in 2023
Statistics Canada recorded 326,571 deaths in 2023. With roughly half of adults lacking a valid will, a very large share of those estates entered succession with no clear instructions, which is the single biggest risk factor for a family dispute.1
2. Most contested estates settle before trial
Canadian estate-litigation firms estimate that the large majority of contested estates settle out of court rather than going to a full trial. That means court-judgment counts badly understate how often families actually fight, because most conflicts are resolved privately after lawyers are already involved.2
3. Six legal grounds to challenge a will
A Canadian will can be challenged on six recognized grounds: lack of testamentary capacity, improper execution, lack of knowledge and approval, failure to provide for dependants, undue influence, and fraud or forgery. Lack of capacity and undue influence are the most frequently litigated, and both are far easier to raise when a will is homemade, vague, or made late in life.3
4. British Columbia lets courts rewrite an unfair will
Under section 60 of British Columbia's Wills, Estates and Succession Act, a court can vary a will that fails to make "adequate, just and equitable" provision for a spouse or child, even if the will is otherwise valid. Claims must be filed within 180 days of probate. BC is the only province where a court can override a parent's clear wishes on fairness grounds, which makes it a national hotspot for estate litigation.4
The will gap that drives conflict
Most inheritance disputes trace back to one root cause: no will, or an old and unclear one. The numbers on that gap are stark.
5. About half of Canadians have no will
A 2023 Angus Reid Institute survey found that 50 percent of Canadians have no will, 37 percent have an up-to-date will, and 13 percent have one that is outdated. Dying without a will (intestacy) hands distribution to a rigid provincial formula that often satisfies no one in the family.5
6. Four in five younger adults have nothing in place
The same survey found that roughly 80 percent of Canadians under 35 have no will, and even 20 percent of those aged 55 and over still have none. For more detail on who does and does not have one, see our companion article on how many Canadians have a will.6
7. Only about 30 percent have a full estate plan
An RBC Royal Trust study (Ipsos) found 74 percent of Canadians aged 55 and over have a will, but only about 30 percent of all Canadians have a complete estate plan that also covers powers of attorney and beneficiary designations. Partial planning leaves exactly the gaps that fuel later disputes.7
8. Most Canadians feel lost on probate
CPA Canada has reported that 61 percent of Canadians do not feel knowledgeable about probate or how a will's validity is established. That confusion makes families more likely to challenge, and more likely to be challenged, when an estate is settled.8
The $1 trillion wealth transfer
The stakes are rising because more wealth is changing hands than ever before, much of it locked in real estate.
9. About $1 trillion is passing between generations
CPA Canada describes a wealth transfer of roughly one trillion dollars moving from Canadian baby boomers to their Gen X and millennial heirs, the largest in the country's history. Bigger estates, more blended families, and high-value homes all raise the odds and the cost of a fight.9
10. Inheritances are increasingly tied up in property
As home values rose, more of the average estate sits in a single illiquid asset, the family home, that cannot easily be split among children. Industry analyses of Canadian estate litigation point to rising property values and debt as a growing source of conflict, because heirs argue over selling, keeping, or buying out the house.10
What families actually fight about
Disputes cluster around a handful of recurring triggers. Blended families and unspoken expectations top the list.
11. Over 500,000 stepfamilies in Canada
The census counts more than half a million stepfamilies in Canada, and roughly one in eight couple families with children is "blended." Second marriages and children from prior relationships are repeatedly cited by estate lawyers as the single biggest driver of inheritance disputes, because the interests of a surviving spouse and the deceased's own children can directly conflict.11
12. Many families have already argued about money
A 2025 Money Wise Institute study found 19 percent of younger Canadians had already had a disagreement with a sibling about financial fairness, and 18 percent of parents feared their wealth distribution would cause family conflict. The disagreements often start long before anyone has died.12
13. Older Canadians avoid the conversation
An estate-planning study by Willful found that 21 percent of Canadians aged 55 and over believe talking to family about their finances would cause infighting, and 38 percent consider their affairs too private to discuss at all. That silence is precisely what leaves heirs to guess, and to dispute, after the fact.13
14. Avoiding conflict is a top planning goal
An Edward Jones Canada study found 34 percent of Canadians name "ensuring the inheritance is distributed without conflict" as a key factor in their wealth-transfer decisions. People know the risk. The gap is between knowing it and writing a clear will.14
What a dispute costs and how long it takes
Litigation is slow and expensive, and the money usually comes out of the estate the family is fighting over.
| Item | Typical figure (CAD) |
|---|---|
| Estate-litigation counsel, hourly | $350 to $700+ |
| Taking a case to trial | $10,000 to $25,000+ |
| Costs recovered by a winner (partial indemnity) | about 20% to 40% of actual fees |
| BC wills variation filing window | within 180 days of probate |
| General limitation period (e.g. Ontario) | about 2 years |
15. Trials run well into five figures
Taking an estate or civil dispute through to trial in Canada commonly costs between roughly $10,000 and $25,000 or more, with experienced estate-litigation lawyers often billing $350 to $700 an hour. Even a winning party who recovers "partial indemnity" costs usually recoups only about 20 to 40 percent of what they actually paid.15
16. The clock is short, especially in BC
Timing rules shape every dispute. In British Columbia, a spouse or child seeking to vary a will must file within 180 days of probate. Most other will challenges fall under a general limitation period of about two years. Miss the window and the claim is gone, which adds pressure and cost early in the grieving period.16
17. Legal fees keep climbing
A 2024 review of the Canadian legal-fee landscape found 64 percent of firms planned to raise fees, with wills and estates work among the areas seeing the steepest increases. The cost of fighting over an estate is rising faster than inflation.17
How a clear will prevents most disputes
Almost every trigger above, intestacy, ambiguity, blended-family tension, unequal treatment of children, points back to the same fix: a valid will that says clearly what you want and why.
18. A valid will closes the easiest grounds to challenge
A will that is properly made, signed, and (where needed) witnessed, with a named executor and clear gifts, removes the two most common grounds of attack, intestacy and ambiguity, and makes capacity and undue-influence claims much harder to sustain. To understand what happens when there is no will, see dying without a will in Canada. To reduce the risk of a forced-share claim, read how dependants' relief works and how to provide for a spouse and dependent children. For the writing itself, see how to write a will and the will template.
19. Government data confirms wills are a real source of stress
In the federal Canadian Legal Problems Survey, 8.7 percent of Canadians who reported a serious, hard-to-resolve legal problem cited taking care of a will or related financial and health matters for someone, rising to about 13 percent among those aged 55 and over. Planning ahead is the cheapest way to keep your own estate off that list.18
The lesson behind these numbers is simple. Inheritance disputes are rarely about greed alone. They grow out of silence, missing documents, and unclear wishes, all of which a will fixes.

Frequently asked questions
How common are inheritance disputes in Canada?
There is no single national count, but the drivers are widespread: about half of Canadians have no will, deaths exceed 326,000 a year, and a roughly $1 trillion wealth transfer is under way. Estate lawyers report rising caseloads, and most disputes settle privately, so the true number is higher than court records suggest.
What causes most inheritance fights?
The recurring triggers are dying without a will, vague or homemade wills, blended families and second marriages, unequal treatment of children, and disputes over a family home that cannot be easily divided.
Can a will really prevent a dispute?
It removes the most common grounds. A clear, valid will with a named executor, specific gifts, and reasonable provision for a spouse and dependent children eliminates intestacy and ambiguity and makes other challenges far harder to win.
The clearest takeaway: most inheritance disputes are foreseeable, and a properly written will is the cheapest insurance against them. To begin, use our will generator or read how to write a will.
