Does Marriage Revoke a Will in Ontario? Succession Law Reform Act

21 Jun 2026 7 min read No comments Wills & Estate Planning Ontario
📜

Under the updated Succession Law Reform Act, getting married no longer automatically revokes an existing will in Ontario. However, if you finalize a divorce, sign a formal separation agreement, or live separate and apart for at least three years (provided the separation began on or after January 1, 2022), the law now generally treats your ex-spouse as if they passed away, automatically cancelling any gifts or executor roles you left for them.

Life is full of major milestones, and tying the knot or going through a separation are some of the most emotionally significant moments you can experience. For decades, many Ontarians were completely unaware of a hidden legal trap: simply saying “I do” used to instantly cancel their entire estate plan. Because of this old rule, many grieving families were shocked to discover their loved one actually died without a valid document. Thankfully, the provincial government recently modernized these estate laws, leading many people to ask: does marriage revoke a will in Ontario today? Under the current rules of the Succession Law Reform Act, a new marriage safely leaves your existing documents entirely intact. 💍

While protecting your will during a new marriage is a huge relief, the laws surrounding a relationship breakdown have also completely changed. A finalized divorce, or even a long-term legal separation, now severely impacts who inherits your hard-earned assets. Navigating these major life changes can feel incredibly overwhelming, but understanding how the law views your relationship status is vital to protecting your family’s financial future. Most residents choose to work with an experienced estate lawyer from our directory to safely update their documents after a major life event, ensuring their final wishes are properly respected by the Superior Court of Justice. 📝

Step-by-Step Process in Ontario: Updating Your Will After Marriage or Divorce

Because estate laws are governed provincially, the exact rules found in the Succession Law Reform Act apply equally whether you live in Toronto, Ottawa, or Thunder Bay. When your marital status changes, taking a proactive approach to your estate plan is generally the safest way to avoid future family disputes and expensive court battles. 📍

Step 1: Reviewing the Date of Your Last Will

The very first step is checking exactly when your current will was signed. The major changes to Ontario law officially took effect on January 1, 2022. If you were married before this specific date, the old rules might still apply to you, meaning your old will could already be legally void. If you were married after this date, your document remains perfectly valid. Gathering your paperwork and checking the dates with a legal professional can provide incredible peace of mind. 📅

Step 2: Understanding the Impact of Separation

If your relationship ends, you need to understand how the new separation rules affect your estate. Under the Succession Law Reform Act (SLRA), your ex-spouse is automatically treated as if they passed away before you—cancelling any gifts or executor designations—if you are officially divorced or if you are legally “separated” at the time of your death. Crucially, the law recognizes you as separated immediately if there is a signed separation agreement, a court order, or an arbitral award, meaning you do not have to wait to revoke their rights. 💔

If you do not have these formal documents, you must live separate and apart due to marriage breakdown for a period of at least three years immediately preceding your death. However, under the SLRA transition provisions, this automatic 3-year separation rule only applies if your separation began on or after January 1, 2022. If you separated before 2022 and have no agreement, court order, or divorce, your ex-spouse’s rights in your will remain fully active and will not be automatically revoked by the passage of time.

Step 3: Drafting a Brand New Estate Plan

Even though a new marriage no longer throws your old will in the garbage, it is highly recommended to write a brand new one anyway. A new spouse brings new financial responsibilities, and you likely want to ensure they are properly taken care of if something unexpected happens. Creating a new Last Will and Testament allows you to clearly outline exactly what your new partner will receive, while potentially protecting separate inheritances for children from a previous relationship. ✍️

Step 4: Updating Direct Beneficiary Designations

Many people completely forget that their formal will does not usually control their registered investments. Things like a Tax-Free Savings Account (TFSA), a Registered Retirement Savings Plan (RRSP), or a private life insurance policy have their own direct beneficiary forms. You must contact your bank or insurance provider directly to update these names; otherwise, your ex-spouse might still receive a massive cheque outside of the probate process. 💳

How Much Does it Cost?

Managing the financial costs of updating your estate plan is a very common concern. While you might be tempted to save money by doing nothing, an outdated will can cost your surviving family tens of thousands of dollars in legal fights and excess probate fees. 💵

  • Basic Will Package: Hiring a professional lawyer to draft a standard will and power of attorney documents generally costs between $800 and $1,500 for a single person.
  • Couples Estate Package: If you and your new spouse do your estate planning together, most law firms offer a bundled package ranging from $1,200 to $2,500.
  • Separation Agreements: If you are separating and need a formal legal agreement to protect your estate early, family lawyers typically charge $2,500 to $5,000+ depending on negotiations.
  • Ontario Probate Fees: A clear, updated will helps streamline the court process, but the estate will still owe the Estate Administration Tax, which is roughly 1.5% on probatable assets over $50,000.

How Long Does the Process Take?

Updating your life after a marriage or divorce requires patience, but securing your estate plan is usually a surprisingly fast process once you decide to take action. ⏱️

  • Drafting a New Will: Once you meet with an estate lawyer, having your new documents fully drafted, reviewed, and legally signed generally takes just 2 to 4 weeks.
  • Finalizing a Divorce: The legal process to officially end a marriage through the court system usually takes 4 to 6 months for a simple, uncontested joint application.
  • Applying Separation Rules: For an informal separation to automatically cancel an ex-spouse’s inheritance, you must live separate and apart for a period of at least 3 years immediately preceding your death (and the separation must have begun on or after January 1, 2022). If you sign a formal separation agreement or get a court order, the cancellation of their rights is immediate.
  • Updating Beneficiaries: Changing the named beneficiary on a life insurance policy or RRSP is incredibly quick, usually taking just a few days after submitting the correct form to your financial institution.

Frequently Asked Questions (FAQ)

Does a common-law relationship automatically revoke my will?

No, it absolutely does not. Moving in with a partner and becoming common-law has never automatically cancelled an existing will in Ontario. However, common-law spouses do not have the same automatic inheritance rights as legally married couples, making it incredibly important to proactively write a new will to ensure your partner is financially protected.

What happens if I was legally married before January 1, 2022?

This is a highly critical timeline. If you signed a will and then got married before January 1, 2022, the old laws likely apply to you. Under the old rules, your marriage completely cancelled your existing will (unless the document explicitly stated it was made in contemplation of that specific marriage). You should urgently speak with a legal professional to verify if you currently have a valid will.

Will a divorce cancel the beneficiaries on my life insurance?

Generally, no. The recent updates to the Succession Law Reform Act only automatically remove an ex-spouse from your formal Last Will and Testament. These provincial rules do not automatically apply to direct beneficiary designations on life insurance policies, RRSPs, or TFSAs. You must manually contact your insurance company or bank to completely remove your ex-partner’s name.

Do I need to go to court to officially update my will?

No, updating your personal estate plan is a private matter between you and your lawyer. You do not need to register your new will with the Superior Court of Justice or ask a judge for permission. The court only gets involved much later, during the formal probate process, after you have passed away.

Does getting married cancel my Power of Attorney?

No, marriage does not cancel or revoke an existing Power of Attorney for Property or Personal Care. If you previously named your parents or a sibling to make medical decisions for you, they remain in total control even after you get married. If you want your new spouse to handle your health and finances during an emergency, you must draft brand new Power of Attorney documents.
