Do you need a lawyer to probate a will in Ontario?

Updated 2026-08-17 · 4 minute read · checked against official Ontario sources

After a death, one question comes up fast: do I need to hire a lawyer for probate? We will not answer that for you. For some estates, a lawyer truly is the right help. For others, people handle the paperwork themselves. What we can do is show what Ontario’s own pages say — and lay out the honest choices.

Who the government’s instructions speak to

Ontario’s official probate page talks straight to the reader. It says if you need to apply for probate, you can apply to the Ontario Superior Court of Justice. You can ask for a Certificate of Appointment of Estate Trustee — the court paper most people call probate — or a Small Estate Certificate. The steps that follow are written the same way. You complete the court forms. You gather the documents. You pay the estate tax when you file. Every step is addressed to you.

The small-estate page goes further. It plans for applicants who have no lawyer. It says court staff will let you or your lawyer know if there is a problem. To check on your application, you can contact your lawyer — or the estates court office yourself.

One honest note. We looked for an official sentence that says, in plain words, that you may apply without a lawyer. We did not find one on Ontario’s pages. What we found is what you just read: instructions written to you, and pages that expect some applicants to have no lawyer.

What the same pages say about lawyers

The probate page has a section called Speaking to a lawyer. It says probate takes time and work. It says estate matters can be complicated. And it says, in its own words, “you may want to speak with a legal professional.”

It also tells you to contact a lawyer if you want the lawyer to apply for probate on your behalf. And it suggests talking to a lawyer if you think someone may challenge your application, or make a claim against the estate.

Read those words again. May want to. If you want. The page describes hiring a lawyer as a choice you make.

Court staff cannot help with the forms

Here is the fact that matters most if you go without a lawyer. Ontario’s page says court staff cannot give you advice about your case — not even advice about filling in the forms. The same passage notes that a lawyer can help you complete the forms.

So there is no help desk at the courthouse. Nobody there will check your forms before you file. Staff look at your application only after you file it — and applications with mistakes get sent back. Our guide on why probate applications get sent back lists the common reasons. Without a lawyer, careful preparation is everything.

Many estates really do need a lawyer

Now the other side, just as honest. Some estates should go to a lawyer.

The government’s page gives one example: someone may fight the application or make a claim against the estate. There are more. We publish our own list — the 28 kinds of estates we send to a lawyer. No will. A will changed by hand. A person under 18 inheriting. Situations that need real judgment, not forms.

Our software asks about these situations first, for free, before any payment. If your estate is one of them, we say so and stop.

Free help finding a lawyer

Talking to a lawyer does not have to cost anything at the start. The Law Society of Ontario runs the Law Society Referral Service. You send a request online. They give you the name of a lawyer or licensed paralegal. That person gives you a free meeting of up to 30 minutes, to help you understand your rights and choices. The request, the referral, and the first meeting are all free. The service is for people who live in Ontario. You can start any time at findlegalhelp.ca.

A simpler path for smaller estates

One more thing worth knowing. Ontario has a simpler probate process for smaller estates. The official page says you can use it when the estate is worth $150,000 or less. That number is set in law — a rule called O. Reg. 110/21. Our small estate guide explains how it works.

Three honest ways to get probate done

  • Do it yourself with the government’s pages. The official court forms are free to download. Our forms guide lists every one, and our guide on how to probate a will walks through the steps. You fill in the forms, you check them, you file. Just remember: court staff cannot check your work.
  • Use self-help software. This is what we make. It asks plain questions, fills the official court forms from your answers, and you review and confirm every answer. It is a middle path: less money than hiring a lawyer, more help than doing it alone.
  • Hire a lawyer. The lawyer applies for probate on your behalf and takes on the paperwork. For the estates on that list — and any estate where a fight looks likely — this is the right path. The free half-hour above is a good first step.

All three doors are honest. Pick the one that fits the estate. If you are not sure, spend the free 30 minutes first.
