Conflicting Wills in Canada — Which Will Wins

Last updated July 4, 2026 · 4 min read
Quick answer
When multiple Canadian Wills exist after death, the most recent valid Will generally governs. The most recent Will typically includes an explicit revocation clause ('I revoke all prior Wills and codicils') which makes earlier Wills void. Without explicit revocation, conflicts are resolved by — implied revocation where new Will substantially contradicts prior; coexistence where Wills can be read together (e.g., one for Canadian assets, one for foreign assets, or a Will plus codicil amending it); and court interpretation where ambiguity exists. Common scenario — testator made multiple Wills over years; finding the most recent is the executor's first task. Older Wills should be destroyed when replaced; if found, marked 'REVOKED' to prevent confusion.

When multiple Canadian Wills exist after death, sorting them out is the executor's first task. The general rule is simple — most recent valid Will wins — but specific situations create complexity.

The general rule

Most recent valid Will governs. Standard Will practice includes a revocation clause:

"I revoke all prior Wills and codicils made by me."

This explicitly wipes out earlier Wills, making the new Will the sole authority.

How conflicts arise

Multiple Wills over years. Testator made Wills in 1995, 2005, 2015, 2020. Each likely revokes the prior, but they may all be physically found at death.

No revocation clause. Some Wills (especially DIY or older) lack the revocation clause. Multiple Wills may then coexist or conflict.

Codicils amending Wills. A codicil amends specific provisions of an existing Will. Multiple codicils may exist over time.

Wills in multiple jurisdictions. Canadian Will for Canadian assets; foreign Will for foreign assets. Both valid, covering different territories.

Lost/destroyed earlier Will plus new one. Most recent governs.

Identifying the most recent

Executor's first task:

  1. Search testator's records, lawyer's office, safety deposit box, home safe
  2. Identify all Wills found
  3. Note dates of each
  4. Note signatures and witnessing
  5. Determine which is most recent valid

Where Wills might be:

  • Lawyer's office (if lawyer-drafted)
  • Home safe
  • Safety deposit box (note: bank may freeze on death)
  • Specific Will registry (BC, Manitoba, Saskatchewan have registries)
  • Specific online service account (if online Will)

Revocation clause

Standard wording in modern Wills:

"I, [Name], of [City, Province], hereby revoke all prior Wills and testamentary dispositions made by me at any time."

This explicit revocation makes the new Will the sole governing document. Older Wills are void.

Without explicit revocation:

  • Older Will may still operate to the extent it doesn't conflict
  • Implied revocation through contradiction is possible but harder to establish
  • Specific to interpretation

Codicils

A codicil amends specific provisions of an existing Will rather than replacing it.

Example:

  • 2015 Will leaves $50,000 to nephew
  • 2020 Codicil changes that to $25,000 to nephew

Read together — 2015 Will governs with the $50,000 amount changed to $25,000 per the codicil.

Multiple codicils:

  • Each can amend prior provisions
  • Most recent codicil prevails to extent of conflict

Codicils are valid but increasingly out of favour:

  • Modern practice prefers full Will replacement for clarity
  • Multiple codicils complicate interpretation

Wills in multiple jurisdictions

Common scenario — Canadian + foreign Will:

"I leave my Canadian assets per my Canadian Will dated [date], and my US assets per my US Will dated [date]."

Both Wills can coexist, each governing specific assets. Coordination critical to:

  • Avoid overlap (which Will covers a specific asset)
  • Avoid conflicting provisions
  • Ensure both executors aware

Multiple wills strategy in Ontario — primary Will for assets requiring probate; secondary Will for assets that don't (private company shares, specific arrangements). Both coexist for tax/fee optimization.

What if there's no clear most recent

Dating problems:

  • Will not dated
  • Date ambiguous
  • Specific to interpretation

Resolution:

  • Witness signatures with dates may help
  • Lawyer records (if any) help
  • Specific contextual evidence
  • Court interpretation if needed

Court determination

If executor cannot determine which Will governs:

  • Application to court
  • Affidavits from parties
  • Specific evidence presented
  • Court orders which Will to be probated

Costs:

  • Legal fees can be significant
  • Estate pays
  • Delays administration

Prevention through clear documentation, dated Wills, and explicit revocation clauses.

After probate

If probate has been granted on what was believed to be the most recent Will, and a newer Will is later found:

Possible outcomes:

  • Probate revoked and re-granted on newer Will
  • Specific provincial procedures apply
  • Court application required
  • Specific to time elapsed and what's been distributed

Time-sensitive — earlier discovery is easier to resolve.

Best practices to prevent conflicts

For testators:

  • Include explicit revocation clause in every new Will
  • Destroy or mark "REVOKED" on old Wills when replaced
  • Register Will (in provinces with registries)
  • Tell executor where current Will is located
  • Update consistently rather than accumulating multiple

For multiple jurisdictions:

  • Clear scope in each Will
  • Both executors aware of both Wills
  • Coordinate provisions

For codicils:

  • Limit use; full Will replacement preferred
  • If using, reference original Will clearly

What we focus on at It's Simple Will

The Will Creator produces Wills with standard explicit revocation clauses. Updating through the platform replaces the prior Will cleanly rather than creating multiple documents to coordinate.

Frequently asked questions

What if multiple Wills are found?

The most recent valid Will generally governs. Earlier Wills are typically revoked by the new Will (either explicitly through a revocation clause or implicitly by contradicting provisions). Executor needs to identify the most recent and confirm it's valid.

What if the Wills don't have dates?

Problematic. Specific to circumstances — handwriting analysis, signatures of witnesses with dates, contextual clues, lawyer records may help establish sequence. Court may need to determine. Generally, the Will that appears more recent based on available evidence governs.

What's a revocation clause?

Standard provision in new Wills — 'I revoke all prior Wills and codicils made by me.' Wipes out earlier Wills. Should be included in every new Will. Without explicit revocation, older Wills may still operate to the extent they don't conflict with new Will.

Can I have separate Wills for different countries?

Yes — multiple Wills can coexist if they cover different assets. Common — Canadian Will for Canadian assets; US Will for US assets. Each governs its specific territory. Coordination essential to ensure no conflict on shared assets.

What about a Will and a codicil?

They coexist — codicil amends specific provisions of the Will but doesn't replace it. Read together. If they conflict, codicil (later document) typically prevails to the extent of conflict.

What if a new Will is found after probate has been granted?

Probate can potentially be revoked or revised if a more recent valid Will is found. Specific provincial procedures apply. Court application typically required. Time-sensitive — earlier the better.
