How to Contest a Will in British Columbia: Legal Grounds and Court Procedure

To contest a will in British Columbia, a challenger must formally dispute its validity in the Supreme Court of British Columbia on recognized legal grounds—such as lack of testamentary capacity, failure to adhere to statutory execution formalities, lack of knowledge and approval, suspicious circumstances, fraud, or undue influence—or bring a distinct statutory claim under the Wills, Estates and Succession Act (WESA) to vary its terms or rectify an error. Pax Law Corporation assists executors, beneficiaries, and disinherited family members through the exact procedural frameworks required to navigate estate litigation across the province.

Summary: Legal Grounds to Contest a Will in BC

The legal mechanism and evidentiary burden depend on the exact relief sought. The table below outlines how BC law approaches will challenges:

Legal Grounds to Challenge the Validity of a Will

1. Testamentary Capacity

In British Columbia, individuals aged 16 or older may make a will, provided they possess the requisite mental capacity under section 36(1) of the Wills, Estates and Succession Act (WESA). As confirmed by the British Columbia Court of Appeal in Conner Estate v Worthing, 2021 BCCA 231 (at paragraph 45):

“To have testamentary capacity, the testator must be aware of her assets, appreciate who the beneficiaries are, and understand the effect of making a Will. The test does not require the testator to view the Will with the ‘eye of a lawyer.'”

The court does not evaluate whether the testamentary disposition was fair or whether the will-maker grasped complex legal technicalities. Paragraph 52 of Conner clarifies that identifying clerical or drafting errors is not an element of capacity. If the deceased understood their assets, potential claims on their estate, and the legal consequences of the distribution, the test is satisfied.

2. Formal Execution Requirements

Under WESA section 37(1), a valid will must be in writing, signed at its end by the will-maker (or acknowledged as their signature) in the presence of two or more witnesses present at the same time, and signed by two or more of those witnesses in the presence of the will-maker. Pursuant to section 40(1), witnesses must be at least 19 years of age. Sections 35.1 to 35.3 accommodate electronic wills, allowing electronic signatures and remote witnessing via electronic communication technology under strict statutory safeguards.

Section 38 provides specific exceptions for active members of the Canadian Armed Forces, while section 80 governs the formal validity of wills executed outside the province.

3. Beneficiary as Witness

If an individual signs a will as a witness, or is the spouse of a witness, or signs at the direction of the will-maker, any testamentary gift made to that individual or their spouse is typically void pursuant to WESA section 43(1). Under section 43(4), this does not void the entire will. Furthermore, under section 43(3), the Supreme Court of British Columbia has discretion to declare the disposition valid if satisfied that the will-maker intended to make the gift.

4. Knowledge, Approval, and Suspicious Circumstances

The party seeking to establish the will (the propounder) must prove three core elements on a balance of probabilities: compliance with statutory execution requirements, knowledge and approval of the will’s contents, and testamentary capacity (Leung v Chang, 2013 BCSC 976, at paragraph 26). Where a will is formally executed and read to or by the will-maker who appears to understand it, a rebuttable common-law presumption arises that the will-maker knew and approved of its contents.

This presumption can be displaced by evidence establishing “suspicious circumstances,” defined in Leung (at paragraphs 29–30) as circumstances surrounding the preparation of the will, calling capacity into question, or showing that free will was overborne by coercion or fraud. Paragraph 32 confirms that mere conjecture does not suffice; there must be actual evidence that casts genuine doubt on capacity or approval. Once established, the initial presumption is spent, and the propounder must affirmatively establish knowledge, approval, and testamentary capacity.

5. Undue Influence and Fraud (WESA Section 52)

Under common law, undue influence requires coercion that overpowers the will-maker’s autonomy, turning the document into something other than their genuine act. Persuasion, argument, or advice alone does not constitute undue influence if free agency remains intact (Leung, at paragraph 35).

WESA modified the evidentiary rules for estates through section 52. If a challenger establishes that a beneficiary was in a position where the potential for dependence or domination of the will-maker existed, the statutory burden shifts: the party defending the will or gift must prove that undue influence was not exercised. Suspicious circumstances alone do not trigger this statutory shift under section 52; the relationship of potential dependence or domination must be established by evidence (Leung, at paragraph 34).

6. Revocation, Separation, and Curative Powers (Section 58)

A will cannot be revoked merely by an informal change of circumstances. Under WESA section 55, revocation requires a subsequent valid will, a formal written declaration of revocation, physical destruction with intention to revoke, or an order under section 58. Where spouses separate, section 56(2) revokes any appointment of the former spouse as executor/trustee and cancels gifts made to them, but preserves the remainder of the will.

Under WESA section 58, the Supreme Court of British Columbia holds broad curative authority to declare a non-compliant document, record, or writing effective as a will, revocation, or alteration. As noted in Paige v Noel, 2025 BCCA 358, the court must determine on a balance of probabilities whether the document embodies the deceased’s fixed and final testamentary intention at the material time. Preliminary notes or instructions for a future will do not satisfy this standard unless the document itself was intended to effect testamentary disposition.

Court Procedure: Step-by-Step in the BC Supreme Court

Estate challenges are governed by Part 25 of the Supreme Court Civil Rules (B.C. Reg. 168/2009).

1. Pre-Grant: Filing Form P29 (Notice of Dispute)

Before an estate grant (probate or administration) or foreign resealing is issued, an interested person or someone claiming under a prior or subsequent will can halt the process by filing a Notice of Dispute under Rule 25-10(1) in Form P29. This document must set out the precise grounds of dispute.

• Filing Deadline: Must be filed before an estate grant or authorization to obtain estate information is issued.
• Effect: Prevents the probate registry from issuing the grant while valid.
• Duration: Remains in effect for one year unless renewed by court order, removed by the court under Rule 25-10(10), or terminated by proof in solemn form under Rule 25-10(12).
• Limitation: A Notice of Dispute does not determine invalidity; it is an interim procedural hold requiring substantive court proceedings to adjudicate the will.

2. Proof of Will in Solemn Form

To obtain a final judicial determination on validity, an application for proof of will in solemn form is required under Rule 25-14(4):

• If an existing proceeding is already underway where the order can properly be sought, the applicant files a notice of application within that action.
• If no proceeding exists, the applicant must initiate a new proceeding by petition under Rule 16-1.

Under Rule 25-14(8), the court possesses broad case-management authority to frame the issues, direct the manner of evidence, add parties, and order a trial if necessary.

3. Post-Grant: Revocation of an Estate Grant

If an estate grant has already been issued by the court registry, filing a Notice of Dispute is no longer available. A challenger must apply under Rule 25-14(1)(c) to revoke the grant. Pursuant to Rules 25-14(5)–(6), this application must be made under Part 8 and served personally on the personal representative, along with all interested parties.

4. Critical Distinctions in Deadlines

It is vital not to conflate procedural notice periods with litigation limitation periods:

• The 21-Day Rule: Under Rule 25-2, an applicant for a grant must deliver notice to interested parties at least 21 days before submitting their application materials (Gill v Gill, 2024 BCSC 526, at para 87). This is a statutory notice period, not an expiration deadline for a challenger’s substantive rights.
• The 1-Year Rule: This governs the operational life of a Form P29 Notice of Dispute, not the overarching time limit to dispute will validity.

Alternative Statutory Remedies: Variation vs. Rectification

Wills Variation Under WESA Section 60

A wills variation claim does not dispute validity. Rather, it assumes the will is legally valid but challenges its fairness. Section 60 permits a surviving spouse (married or common-law for at least two years pursuant to section 2(1)) or child of the deceased to petition the court if the will fails to make “adequate provision for the proper maintenance and support.” Under section 61(1), this claim must be commenced within 180 days from the issuance of the representation grant, and pleadings must be served on the executor and, where required, the Public Guardian and Trustee.

Rectification Under WESA Section 59

If a will is validly executed but fails to reflect the will-maker’s true instructions because of an accidental slip, omission, or misunderstanding, section 59 permits the court to order rectification. A section 59 application must also be brought within 180 days from the date the representation grant is issued, unless the court grants leave for an extension.

Costs and Strategic Practicalities

Under Rule 25-15(4) of the Supreme Court Civil Rules, a respondent who simply requires that a will be proved in solemn form for the limited purpose of cross-examining witnesses will generally not be penalized with court costs, provided the court finds there was reasonable ground for the request. Strategic decisions must be calibrated to whether the estate grant has issued and whether the underlying cause of action concerns execution defects, lack of capacity, undue influence, or a variation claim.
