Do I Need a Lawyer to Make a Will in Ontario?

If you're putting off writing your will because you're not sure whether you actually need a lawyer, you're not alone. It's one of the most common questions Ontario residents ask before starting their estate plan — and the honest answer is: it depends on your situation.

The short version: you are not legally required to hire a lawyer to make a valid will in Ontario. The law only cares that your will meets certain formal requirements. But whether you should use a lawyer is a different question — and for most people, the answer is yes, especially once you understand what can go wrong with a DIY will and how those mistakes are usually only discovered after the will-maker has passed away, when it's too late to fix them.

This guide walks through exactly what Ontario law requires, when a self-made will can work, when it's genuinely risky, and what it typically costs to have a lawyer prepare one.

The Short Answer

No, Ontario law does not require you to use a lawyer to make a legally valid will. Under the Succession Law Reform Act (SLRA), a will is valid as long as it meets specific formal requirements around how it's written, signed, and witnessed. A carefully completed DIY will or will kit can satisfy those requirements.

However, "legally valid" and "does what you actually want it to do" are not the same thing. A lawyer's value isn't just making sure your signature is in the right place — it's making sure your estate is distributed the way you intend, minimizing tax and probate costs, and avoiding the kind of ambiguous wording that leads to family disputes and court challenges after you're gone.

What Makes a Will Legally Valid in Ontario?

To be valid, a formal (typed) will in Ontario generally must:

• Be in writing — typed or printed documents are standard, though handwritten wills have their own rules (see below)

• Be signed by the testator (the person making the will), or by someone else in their presence and at their direction, at the end of the document

• Be signed in the presence of two witnesses, both present at the same time

• Be signed by both witnesses, in the presence of the testator

• Be made by someone at least 18 years old, with limited exceptions (for example, minors who are married or serving in the military)

• Be made with testamentary capacity — the person must understand what a will is, what they own, and who might reasonably expect to benefit

Since a 2021 amendment to the SLRA, Ontario also permits virtual witnessing using audio-visual technology (like a video call), provided at least one witness is a licensed lawyer or paralegal when the will is signed in counterpart. This flexibility was introduced during the pandemic and has since been made permanent.

Ontario law also includes a curative provision: if a will doesn't perfectly meet the formal signing and witnessing requirements, a court now has the discretion to declare it valid anyway, if there's clear evidence it reflects the deceased's genuine intentions. This is a helpful safety net, but it involves a court application — it's not something you want to rely on by design.

Holograph Wills: The Handwritten Exception

Ontario also recognizes holograph wills — a will that is entirely in the testator's own handwriting and signed by them. Holograph wills don't require any witnesses. They're legally valid, but they're also one of the most commonly challenged types of will, because they're often written quickly, informally, and without legal guidance — leaving room for missing clauses, unclear language, or questions about capacity and intent.

When a DIY Will Might Be Enough

A self-drafted will or an online will kit can be a reasonable option if:

• Your estate is simple and modest in value

• You have no minor children requiring guardianship provisions

• You're leaving everything to one person or splitting it evenly among a small number of people with no complications

• You don't own a business, foreign property, or complex investments

• You don't need trust planning for beneficiaries with disabilities, addiction concerns, or creditor issues

• You're comfortable following the execution (signing and witnessing) rules precisely

Even in these cases, it's worth having at least one conversation with a lawyer or having the document reviewed before signing — many law firms offer this at a modest flat fee.

When You Should Hire a Wills Lawyer

A lawyer becomes far more valuable — and arguably necessary — if any of the following apply to you:

• You have minor children. A lawyer can properly draft guardianship provisions and set up trusts to manage their inheritance until they're old enough to receive it directly.

• You're in a blended family. Second marriages, stepchildren, and children from previous relationships create a real risk of disputes without carefully drafted language.

• You own a business. Succession planning, shareholder agreements, and business valuation issues need to be coordinated with your will.

• You have significant or complex assets, including multiple properties, investments, or assets outside Ontario or Canada.

• You want to minimize probate fees (Estate Administration Tax) through proper structuring, such as multiple wills for business owners.

• You have a beneficiary with a disability, where an improperly drafted inheritance could disqualify them from government support programs like ODSP.

• You're worried about a family member contesting the will, or you want to reduce someone's inheritance — situations that require careful, defensible drafting.

• You want powers of attorney for property and personal care done at the same time, which most lawyers bundle with wills as part of a complete estate plan.

In short: the simpler your life and assets, the more realistic a DIY approach becomes. The more moving parts, the more a lawyer's judgment protects both you and the people you're leaving behind.

The Real Risk of DIY Wills

The problem with DIY wills isn't that they're always invalid — it's that mistakes are often invisible until it's too late to correct them. Common issues Ontario courts and estate lawyers see include:

• Improper execution — missing a witness, a witness who is also a beneficiary (which can void that beneficiary's gift), or documents signed in the wrong order

• Ambiguous language that leaves the court to interpret what you "probably meant"

• Outdated wills that weren't updated after a marriage, separation, divorce, or the birth of a child

• No residue clause, leaving out how to handle assets not specifically listed

• Failing to account for jointly held assets or named beneficiaries (like RRSPs or life insurance), which don't pass through a will at all and can create unintended results

• No alternate executor or beneficiaries named if the first choice cannot act or predeceases you

Because the person who made the mistake is no longer alive to clarify their intentions, these errors often end up being resolved by a court — at a cost, in time, and in family relationships, that far outweighs what a lawyer would have charged to draft the will properly in the first place.

How Much Does It Cost to Hire a Wills Lawyer in Ontario?

Costs vary by firm, region, and complexity, but as a general guide:

• A simple, single will for an individual with a straightforward estate is often a flat fee in the low hundreds of dollars.

• Mirror wills for couples (where spouses leave mirrored provisions to each other) typically cost somewhat more than a single will, but less than two individual wills purchased separately.

• Complex estates — involving business succession, trusts, blended families, or multiple wills for probate planning — are usually billed at a higher flat fee or hourly rate, reflecting the additional drafting and planning involved.

Many Ontario firms also bundle a will with powers of attorney for property and personal care as a package, which is usually more cost-effective than purchasing each document separately.

When comparing cost, it's worth weighing the one-time fee for professional drafting against the potential cost of a legal challenge, a probate delay, or an unintended tax result — expenses that can run into the thousands of dollars and take years to resolve.

Do I Need a Lawyer to Make a Will in Ontario? Bottom Line

You're not legally required to hire a lawyer to make a valid will in Ontario, and for very simple estates, a properly executed DIY will can hold up. But a lawyer brings something a template can't: judgment about your specific family, assets, and risks — and a document built to withstand scrutiny after you're no longer here to explain what you meant.

If your situation involves children, a business, blended family dynamics, or any assets outside the ordinary, speaking with a wills and estate lawyer is one of the most protective (and often surprisingly affordable) steps you can take for the people you love.
