These short answers explain the general rule. Each subject will also have its own detailed Ontario guide, with sources, a review date and links to related services.
Understand the planning process, what to confirm before a home-signing visit, and why mobile attendance does not replace legal advice or execution requirements.
Read the mobile-signing guide →Use a short initial-call brief and a practical planning worksheet for people, documents, decisions and open questions.
Open the appointment checklist →Separate financial authority from treatment decisions and identify assumptions worth reviewing before a problem arises.
Read the spouse and POA guide →Work through caregiving, management of a child's inheritance and parents' lifetime decision-making as separate planning questions.
Open the new-parent planning checklist →Learn how an Ontario estate administration lawyer helps estate trustees with probate, assets, debts, taxes, beneficiary communication and distribution.
Read the estate-administration guide →Learn how mirror wills work for Ontario couples, what they can and cannot guarantee, and when a more tailored estate plan may be needed.
Read the mirror wills guide →A practical guide to credentials, estate-planning experience, fees, signing support and the questions worth asking before you hire a lawyer.
Read the Mississauga guide →Learn how an Ontario estate planning lawyer helps with Wills, Powers of Attorney, asset review, signing and a plan that fits your family.
Read the estate-planning guide →Learn what affects the timeline, what can cause delays and how to keep the planning, review and signing process moving.
Read the timeline guide →Compare what each document covers, when authority begins and why many Ontario adults need both forms of Power of Attorney.
Compare the two Powers of Attorney →Ontario law does not require a lawyer, but legal advice can help with capacity, wording, witnesses and whether the document will work when needed.
Read when legal advice helps →Learn when a court may validate a defective Will and why Ontario law on electronic-only testamentary documents remains unsettled.
Read the Ontario law guide →Your estate is distributed under Ontario’s intestacy rules, not according to unwritten wishes. Someone may need to apply to the court for authority to administer the estate, and a common-law spouse does not automatically inherit under those rules.
Read the detailed guide →A Power of Attorney is a legal document that lets you name someone to make certain decisions for you. Ontario has separate documents for property and for personal care.
Learn about Powers of Attorney →Not always. The result can depend on whether there is a valid Will, whether the deceased had children, the value and ownership of assets, and other legal rights that may apply.
Plan for your family →Ontario’s intestacy rules do not give a common-law spouse the same automatic inheritance rights as a married spouse. Other claims may be possible, but they are different from automatic inheritance.
Why a Will matters →Probate may be required when a bank, land registry or another institution needs court confirmation of an estate trustee’s authority. Whether it is needed depends on the Will and the assets involved.
Learn about probate →The role can include locating the Will, protecting assets, identifying debts and taxes, keeping records, communicating with beneficiaries and distributing the estate properly.
See estate administration services →Ontario calls it Estate Administration Tax. The amount is based on the value of the estate covered by the application. Rates and filing requirements should be checked before relying on a calculation.
See Ontario’s current information →Some assets may pass outside an estate or may not require probate, but there is no one method that fits every family. Planning must also consider taxes, control, creditor issues and possible disputes.
Discuss coordinated planning →No. A Power of Attorney ends when the person who gave it dies. After death, authority comes from the Will and, when required, the court appointment of an estate trustee.
Understand the two roles →No. A person acting under a Power of Attorney cannot make or change the grantor’s Will. The attorney must act within the authority and duties created by Ontario law and the document.
Learn about an attorney’s authority →Review it after major changes such as marriage, separation, a new child, a death, a move, a business change or a significant change in assets. A regular review also helps catch outdated choices.
Review your estate plan →A document is not reliable merely because it was generated online. A lawyer can identify legal, family, tax and execution issues that a questionnaire or template may not address.
Explore the Family Protection Plan →Compare the documents, lawyer involvement, review process, signing support and additional planning that may affect the scope and price.
Compare Ontario Will and POA packages →Our publishing standard
Our new guides will answer a focused Ontario legal question in plain language, identify the responsible author or reviewer, show when the information was last reviewed and link to primary legal or government sources where useful.
The goal is simple: help readers understand the issue without pretending that a general article replaces legal advice. Technology supports our lawyers. It does not replace them.
