How to write a will in Ontario without a lawyer

First, the two kinds of valid Ontario will — and which one to pick

Ontario recognizes two kinds of will, and the choice between them is the first decision you make. A formal will (sometimes called an attested will) is a typed or printed document signed by you at the end, in the presence of two witnesses present at the same time, who then sign in your presence. A holograph will is a will written entirely in your own handwriting and signed by you, with no witnesses and no other formality required. Both are fully valid if done correctly — but they are not equally safe.

For most people, the formal witnessed will is the better choice. It is easier for your executor to prove after your death: the witnesses can confirm the signing happened, and the court does not need to verify your handwriting. A holograph will saves the trouble of finding witnesses, but it shifts the proof problem to your estate — after your death, someone will need to prove the handwriting is yours, usually through an affidavit from a person who knew your writing, which adds delay and cost to probate. A holograph will is a good emergency option (written tonight, replaced soon with a formal will) and a poor permanent plan. If you can gather two witnesses, make a formal will.

One more distinction that confuses people: an 'online will' you prepare on a screen and print is not an electronic will. A will prepared digitally and printed on paper, then signed in ink in front of two witnesses, sits comfortably inside Ontario's rules. A will signed purely on a screen, with electronic signatures and no paper original, does not — Ontario does not currently recognize a will signed only electronically. Whatever tool you use to draft, the signing itself must be on paper, in ink, in a room with two witnesses.

The legal requirements: age, capacity, writing, signature

Under the Succession Law Reform Act, R.S.O. 1990, c. S.26, a will must be in writing (section 3). Beyond that, four requirements decide validity. First, age: you must generally be at least 18, with narrow exceptions for married persons and members of the Canadian Forces on active service. Second, testamentary capacity: you must understand the nature of a will, the extent of your property, and the claims of the people who might expect to benefit — if capacity is ever questioned, it is judged at the time you signed. Third, voluntariness: the will must be made freely, without undue influence or coercion from anyone who benefits. Fourth, proper execution: the signing formalities for your chosen kind of will, described below, followed exactly.

Capacity deserves a plain-English note because it is where family disputes start. You do not need to be in perfect health, and a diagnosis alone does not remove capacity — the question is whether, when you signed, you understood what the document does, roughly what you own, and who your natural beneficiaries are. If capacity could be questioned — advanced age, illness, a recent change that disinherits someone — that is a strong reason to have a lawyer involved, or at minimum to have the signing witnessed by people who can later describe your state of mind. A will made without a lawyer is not a will made without evidence; the witnesses are your evidence.

The formal will, step by step (Succession Law Reform Act, section 4)

Section 4 sets the formalities, and Ontario courts enforce them strictly. Follow this sequence in one sitting, in one room, with everyone present together:

• Prepare the complete will in writing and read it through before anyone signs. Nothing should be added after the signature — anything written after your signature is not part of the will, so the document must be finished first.
• Sign at the end of the will, using your usual signature, in the presence of two attesting witnesses who are present at the same time. You may also acknowledge a signature you already made, but signing in front of them is cleaner and leaves no doubt.
• Both witnesses then sign the will in your presence. No special attestation wording is required by the Act, but a short attestation clause (stating that you signed in their presence and they signed in yours) is standard practice and makes probate smoother.
• Initial and number every page. The Act does not require it, but it prevents any later allegation that a page was substituted — a cheap precaution that costs nothing at signing time.
• Do not let anyone sign early, sign later, or sign a separate copy. Counterpart signing — people signing different copies at different times — does not satisfy the 'present at the same time' rule, and a will signed by only one witness is not a valid formal will at all.

The witness rule: two witnesses, neither a beneficiary

This is the rule that ruins more homemade wills than any other, so it gets its own section. Your two witnesses must be adults who are present together, who watch you sign (or acknowledge your signature), and who then sign themselves in your presence. And neither witness — nor the witness's spouse — may be a beneficiary under the will.

The reason is section 12(1) of the Act: where a will is attested by a person to whom, or to whose then spouse, a beneficial gift is given under the will, that gift is void so far as it concerns the witness, the spouse, or anyone claiming under them. The will itself survives — but the very person you intended to provide for gets nothing. Section 12(3) lets a court save the gift if it is satisfied no improper or undue influence was exercised, but that requires a court application after your death, with legal costs, delay, and no guaranteed outcome. Never rely on it.

The practical checklist for witnesses: two adults with no interest in your estate; not beneficiaries, not spouses of beneficiaries; present at the same time, in the same room; signing in your presence after you sign. Neighbours, colleagues, and friends with no stake in the will are ideal. Your executor can witness — section 14 confirms that being an executor does not make someone incompetent as a witness — but as a matter of prudence, choose witnesses who are neither beneficiaries nor executors if you can, so nobody's role can be questioned later. And choose witnesses who are likely to be findable years from now: the executor may need one of them to swear an affidavit confirming the signing during probate.

The holograph will (section 6): entirely handwritten, no witnesses

Section 6 provides that you may make a valid will wholly by your own handwriting and signature, without formality and without the presence, attestation, or signature of a witness. The key word is 'wholly': every word of the will must be in your handwriting. A typed document with a handwritten signature is not a holograph will, and a printed form with handwritten blanks filled in is not one either — if any material part is not in your hand, the document must satisfy the formal witnessed-will rules instead, and without witnesses it will fail.

A holograph will must still show testamentary intent — it must read as a document meant to be your will, not a letter musing about one day making a will. Date it, title it as your last will, name your executor, state your gifts clearly, sign it at the end, and keep it as a single clean document without crossings-out. Alterations on the face of a will are governed by section 18: an alteration must be signed by you beside it to be effective, and an unsigned alteration will be ignored at best and invite a dispute at worst. If you need to change a holograph will, the safer course is to write a new one that revokes the old one.

The trade-off, repeated because it matters: a holograph will is valid without witnesses, but probate will take longer, because your executor must prove the handwriting is yours. For a simple estate with cooperative beneficiaries, that is manageable. For a larger estate, real property, or any situation where someone might challenge the will, the formal witnessed will is worth the small extra effort.

What your will should actually say

A valid will is not just a valid signature — it must also do the jobs you need it to do. Work through these decisions before you draft, because a will that is formally perfect but silent on the important points still leaves your family with problems:

• Revocation clause: state that this will revokes all earlier wills and codicils, so there is no argument about which document governs.
• Executor (estate trustee): name the person who will administer your estate, and name an alternate in case the first cannot or will not act. Choose someone organized, trustworthy, and willing — and tell them you have chosen them before you die, not after.
• Specific gifts: particular items or sums to particular people, described precisely enough that the executor can identify them (account numbers and addresses help; nicknames do not).
• Residue clause: whoever gets 'the rest' of your estate after debts, taxes, and specific gifts are paid. A will without a residue clause leaves part of your estate to intestacy rules — the most common drafting gap in homemade wills.
• Guardians for minor children: a will is where Ontario parents name the person they want to raise their children if both parents die. Name a guardian and an alternate, discuss it with them first, and consider naming a separate trustee to manage any money left for the children.
• Debts, taxes, and funeral wishes: direct that debts and taxes be paid from the estate, and state funeral or burial wishes so your family is not guessing. Note that funeral wishes in a will are guidance to the executor, not a binding order — if a particular wish matters deeply, tell your executor directly as well.
• What happens if a beneficiary dies first: state whether their share passes to their children, to another named person, or back into residue. Without this, a lapsed gift can fall into residue in ways you did not intend.

Changing, revoking, and updating your will

A will is revoked only in the ways section 15 allows: by making a new will that complies with the Act, by a revoking writing made with the same formalities as a will, or by physically destroying it (burning, tearing, or otherwise destroying it) by you, or by someone in your presence and at your direction, with the intention of revoking it. Crossing out a will, telling someone you have changed your mind, or writing a note that is not executed as a will does not revoke it.

Two life events deserve special attention because people get them wrong. First, marriage: since January 1, 2022, marriage no longer revokes a will in Ontario — section 16, the old marriage-revocation rule, was repealed. A will you made before marrying still stands after the wedding, so review it rather than assuming it is gone. Second, divorce and separation: under section 17, if your marriage ends by divorce or nullity (and, since 2022, in defined separation circumstances), gifts to your former spouse and their appointment as executor are treated as revoked, and the will is read as if your former spouse had predeceased you — unless a contrary intention appears in the will. Separation and divorce change what your will does even when you do nothing, so review the will after either event rather than trusting it to still say what you meant.

As a rule, review your will after every major life change — marriage, separation, divorce, the birth or adoption of a child, the death of a beneficiary or executor, a move to another province or country, or a major change in assets — and at least every few years regardless. A small change can be made by codicil (an amendment executed with the same formalities as a will), but if the changes are extensive, a clean new will that revokes the old one is less likely to be misread.

Storing the original — and telling your executor where it is

Probate in Ontario requires the original will, or a court process to prove a copy if the original is lost. A copy alone will not do without that extra process, with its costs and delays — so storage is part of making a valid will, not an afterthought. Keep the original in a safe, dry place: a fireproof box at home, or with a lawyer or trust company if you prefer. Tell your executor exactly where it is, in writing, and keep a copy (clearly marked 'copy') somewhere separate for reference. Do not store the only original in a safety deposit box that your executor cannot access without probate — that circular problem is a classic estate-administration headache.

Also tell your executor the practical facts they will need: where your accounts, property documents, and passwords list are kept, and who your key contacts are (accountant, insurer, financial institution). The will disposes of your estate; the executor's job is far easier when they can find it. And remember that probate — a Certificate of Appointment of Estate Trustee — is commonly required where the estate includes real property or institutional accounts, and Ontario levies an estate administration tax on the value of the estate when probate is granted. Your executor, not your will, handles that process, but a clear, findable original is what lets it start.

When a lawyer IS worth it: honest limits of the DIY route

Writing your own will is legitimate and, for a straightforward estate, entirely sensible. But there are situations where the cost of a lawyer is small compared with the cost of getting it wrong, and honesty requires naming them:

• Blended families or second marriages, where children from different relationships have competing expectations and the risk of a challenge is real.
• A business, a farm, or property in another province or country — different jurisdictions have different succession rules, and an Ontario will may not do what you expect elsewhere.
• A dependant with a disability, where the structure of the gift (for example, a trust) affects their benefits and needs specialist drafting.
• Significant tax exposure, complex investments, or a large estate, where the will interacts with tax planning that a template cannot address.
• Any doubt about capacity, or any beneficiary who may allege undue influence — a lawyer's file notes and independent advice are powerful evidence that the will was yours.
• An unusual wish: disinheriting a spouse or dependant, unequal treatment of children, or conditions on a gift — these invite claims (including dependant-support claims) that a lawyer can help you navigate or document against.

Common DIY mistakes — the checklist before you sign

Run through this list in the room, before anyone picks up a pen. Every item here is a real reason an Ontario will has failed or been delayed:

• Only one witness signed, or the witnesses signed at different times or in different places — the formal will fails outright.
• A beneficiary (or their spouse) witnessed — their gift is void under section 12(1), and saving it needs a court application.
• Something was written after the signature — it is not part of the will, however important it seemed.
• The will was signed electronically only, with no paper original — Ontario does not recognize a purely electronic will.
• No residue clause — part of the estate falls to intestacy and is distributed by statute, not by your wishes.
• No alternate executor or guardian named — if your first choice cannot act, the court or the family must fill the gap.
• The original was lost and only a copy survives — probate becomes a court application to prove the copy.
• The will was never updated after divorce, separation, or a new child — and the Act's automatic rules, not your memory of the will, decide what happens.
