Creating a will is one of the most important steps you can take to protect your assets and provide for your loved ones after you're gone. But with the rise of DIY will kits and online templates, many Canadians are attempting to draft their own wills—often without fully understanding the legal complexities involved.
While it may seem convenient or cost-effective to do it yourself, drafting a will without legal guidance can lead to serious and sometimes irreversible mistakes. These errors can result in confusion, family disputes, delays in the probate process, or even an invalid will.
In this article, we’ll explore the most common mistakes people make when drafting a will without a lawyer and why it’s often in your best interest to consult a qualified Wills and Estates Lawyer to ensure your wishes are legally sound and enforceable.
1. Using Incorrect or Incomplete Legal Language
One of the most common problems with DIY wills is the use of vague, unclear, or incorrect legal language. Estate planning is not just about stating who gets what—it's about making sure your instructions are understood and legally enforceable.
Phrases like “I leave everything to my family” might sound straightforward but can be legally ambiguous. Who qualifies as "family"? Does that include stepchildren? Siblings? Cousins? Without clear definitions, your will may be contested or interpreted in ways you never intended.
A Wills and Estates Lawyer understands how to use precise legal terminology that stands up in court. They can also help you clearly define:
- Beneficiaries
- Asset distribution
- Alternate scenarios (e.g., if a beneficiary dies before you)
- Executor duties and powers
Ambiguity in a will can lead to costly legal battles and stress for your family. Precision matters.
2. Failing to Follow Proper Signing and Witnessing Procedures
Each province in Canada has specific rules for signing and witnessing a will. If you don’t follow these rules exactly, your will could be declared invalid—regardless of your intentions.
For example, most provinces require:
- The will to be signed in ink by the testator (you)
- Two witnesses to be present at the same time when you sign
- Witnesses who are not beneficiaries or spouses of beneficiaries
- Witnesses to also sign the will in your presence
Failure to comply with any of these rules can cause your will to be rejected by the probate court. In some cases, it may result in your estate being distributed as if you had died intestate (without a will), which can significantly disrupt your wishes.
A Wills and Estates Lawyer will ensure that all procedural requirements are met so your will is legally valid and cannot be easily challenged.
3. Forgetting to Appoint an Executor (or Choosing the Wrong One)
An executor is the person responsible for managing and distributing your estate after you die. This includes filing taxes, paying off debts, and distributing assets according to your will.
Many DIY wills either forget to name an executor or choose someone who is not well-suited for the role. Worse, some people name multiple executors without thinking through how decisions will be made jointly, leading to conflicts and delays.
A Wills and Estates Lawyer will help you:
- Choose a capable and trustworthy executor
- Name alternate executors in case your first choice is unable or unwilling to serve
- Clearly outline the executor’s powers and responsibilities
- Choosing the wrong executor can delay probate, create disputes, and even expose your estate to financial mismanagement.
4. Overlooking Digital Assets and Online Accounts
In today’s digital world, many people forget to include online accounts, digital assets, and electronic files in their estate plans. This might include:
- Email and social media accounts
- Online banking and investment accounts
- Cryptocurrency wallets
- Cloud storage and digital photos
- Domain names or online businesses
If not addressed, these digital assets can be lost forever or fall into the wrong hands. DIY wills often fail to provide access instructions or designate who should manage these assets.
A Wills and Estates Lawyer can help you inventory your digital assets and include appropriate language in your will or a separate digital asset memorandum. This ensures a smooth and secure transition of your online presence and assets.
5. Not Updating Your Will After Major Life Changes
Life changes—sometimes rapidly—and your will should change with it. Common triggers for updating your will include:
- Marriage or divorce
- Birth or adoption of a child
- Death of a beneficiary or executor
- Major changes in assets (like buying or selling a home)
- Relocation to a different province or country
DIY wills often get written once and then forgotten. The result? Outdated documents that no longer reflect your wishes or current legal circumstances.
By working with a Wills and Estates Lawyer, you can review your estate plan regularly and ensure it stays aligned with your life situation. Most lawyers recommend revisiting your will every 3 to 5 years or after any major life event.
6. Ignoring Tax Implications and Probate Fees
Many people are unaware of the potential tax burdens and probate fees that can arise after death. For example:
- Capital gains tax may be triggered on certain assets
- RRSPs and RRIFs may be taxed as income
- Probate fees can be significant in provinces like Ontario and British Columbia
- DIY wills rarely account for tax planning. They also may not take advantage of tools like:
- Joint ownership (with right of survivorship)
- Named beneficiaries for insurance or registered accounts
- Testamentary or inter vivos trusts
- Donations or charitable gifts to reduce taxable estate value
A Wills and Estates Lawyer can help you create a tax-efficient estate plan that minimizes losses and maximizes the inheritance left for your loved ones.
7. Leaving Out Guardianship Instructions for Minor Children
If you have children under the age of 18, one of the most important parts of your will is naming a guardian. This is the person who will take legal responsibility for your children if you and the other parent pass away.
DIY wills often omit guardianship instructions altogether—or include vague language that doesn't meet legal requirements. Without clear instructions, the decision may be left to the courts, and your children may end up in a home or care situation you never would have chosen.
A Wills and Estates Lawyer can help you:
- Formally name a guardian
- Include backup guardians in case your first choice is unavailable
- Address financial support for your children through a trust or other mechanisms
This ensures that your children are cared for by someone you trust—and that their needs are financially supported in your absence.
8. Assuming One Will Covers Everything
Many people believe that a simple will is all they need. In reality, a comprehensive estate plan may include several legal documents and strategies, such as:
- Power of Attorney for Property
- Power of Attorney for Personal Care
- Advance Healthcare Directives
- Trusts (testamentary or inter vivos)
- Business succession plans
A basic will may not provide instructions for what happens if you become incapacitated, which can leave your family scrambling for legal authority to manage your finances or make medical decisions.
A affordable wills and estates lawyer takes a holistic approach, ensuring your entire estate and personal care wishes are covered—not just who gets your assets when you die.
Conclusion:
While the idea of drafting your own will may seem like a quick, affordable solution, the potential risks and complications can far outweigh the savings. The smallest error in wording, procedure, or planning can lead to big problems down the line—problems that often surface when it's too late to fix them.
