How to Write a Will in Alberta 2026: Requirements & Best Options

Alberta is in many ways one of the most estate-planning-friendly provinces in Canada. Its probate fees are capped at just $525 for most estates — eliminating one of the main incentives for complex probate avoidance strategies. The province's unique Adult Interdependent Partner framework also gives significant rights to long-term common-law couples.

This guide covers everything you need to know about writing a valid will in Alberta in 2026 under the Wills and Succession Act, SA 2010, c W-12.2, including practical steps, executor duties, and the best options for Alberta residents.

Alberta's Wills and Succession Act: The Legal Framework

The Wills and Succession Act (WSA), which came into force on February 1, 2012, consolidated and modernised Alberta's succession law. Key features include:

• Two witnesses required for a formal will
• Holographic (handwritten) wills accepted without witnesses
• Court discretion to cure defective wills (like BC's WESA)
• Marriage does NOT revoke a pre-existing will
• Adult Interdependent Partners recognised for intestacy
• Domestic partners can waive intestacy rights through an Adult Interdependent Partner Agreement

Formal Will Requirements in Alberta

Under WSA section 14, a formal will must be:

1. In writing (typed or handwritten)
2. Signed at the end by the testator
3. Signed by two witnesses in the presence of the testator
4. The testator must be at least 18 years of age (or be or have been married)

Unlike some other provinces, Alberta's WSA explicitly provides that a gift to a witness or their spouse is void under WSA section 15, but the will itself remains valid.

Alberta's Remarkable Probate Fee Structure

Alberta's probate fees are capped at a maximum of $525 for all estates over $125,000 — making Alberta one of the most cost-efficient provinces for estate administration in Canada:

• Estate value up to $10,000: $35
• $10,001–$25,000: $135
• $25,001–$125,000: $275
• Over $125,000: $525 (maximum)

Contrast this with Ontario's 1.5% on values over $50,000 — on a $1 million estate, Ontario charges approximately $14,250 in probate fees versus Alberta's flat $525. This removes much of the incentive for complex probate avoidance strategies that are popular in Ontario.

However, Alberta still applies an "Estate Administration Fee" in addition to probate fees — this is charged by the Public Trustee when it is involved in the estate, not a general fee on all estates.

The Adult Interdependent Partner: Alberta's Unique Framework

Alberta has a distinctive concept called the Adult Interdependent Partner (AIP), defined in the Adult Interdependent Relationships Act, SA 2002, c A-4.5. A person is an AIP of another if they have lived with them in a relationship of interdependence for:

• At least 3 continuous years, OR
• Any period if the relationship is of "some permanence" and they have a child together
• OR they have entered into an Adult Interdependent Partner Agreement

Under Alberta's intestacy rules, AIPs have similar inheritance rights to married spouses. This is more generous than Ontario (where common-law partners have no automatic intestacy rights) but requires the 3-year threshold (vs BC's 2 years).

An AIP can also enter into an Adult Interdependent Partner Agreement — a formal contract that provides legal certainty about the relationship's nature, which can affect inheritance rights if the parties later separate.

Holographic Wills in Alberta

Under WSA section 15(2), a holographic will that is entirely in the handwriting of the testator and signed by them (but requiring no witnesses) is valid in Alberta. Holographic wills are accepted in cases where:

• The testator was unable to obtain witnesses (emergency situations)
• The testator chose simplicity over formality

However, holographic wills have significant disadvantages:

• More easily contested on grounds of authenticity
• Often lack precise legal language, leading to ambiguity
• May not address all necessary matters (executor, trusts, guardianship)
• Handwriting changes with age/illness, making authentication difficult

Use a formal witnessed will or an online will service. Reserve holographic wills for genuine emergencies only.

Alberta Intestacy Rules: What Happens Without a Will

Under the WSA, if you die without a will in Alberta, your estate is distributed as follows:

With a spouse and/or AIP and children:

If the spouse/AIP is also the parent of all your children:

• If estate is $150,000 or less: entire estate to spouse/AIP
• If estate exceeds $150,000: $150,000 preferential share to spouse/AIP + half of remainder; children share other half

If the children are not all from the current spouse/AIP:

• $150,000 preferential share to spouse/AIP + one-third of remainder; children share two-thirds

With an AIP (no children):

Entire estate to AIP (same as married spouse without children)

Children only (no spouse/AIP):

Children share equally

Executor Duties in Alberta

An Alberta executor (called "personal representative" under the WSA) is responsible for:

• Applying for a Grant of Probate from the Alberta Court of King's Bench
• Locating and valuing estate assets
• Paying debts and expenses
• Filing terminal income tax return (and estate returns if needed)
• Distributing assets to beneficiaries
• Providing a formal accounting to beneficiaries

Personal representative fees in Alberta are guided by case law — typically around 2–5% of the estate value. Many family personal representatives waive this fee.

Enduring Power of Attorney in Alberta

Alberta's Enduring Power of Attorney is governed by the Powers of Attorney Act, RSA 2000, c P-20. An EPA must:

• Be in writing
• Be signed by the grantor and witnessed by one adult witness (not a spouse, adult interdependent partner, or beneficiary)
• Contain language making it enduring despite incapacity

Alberta also has the Personal Directives Act, RSA 2000, c P-6 for healthcare directives.
