Can You Disinherit a Child from Your Estate in Prince Edward Island?

🚫

In Prince Edward Island, you can generally disinherit an independent adult child. However, under the Dependants of a Deceased Person Relief Act, you cannot legally disinherit a child who is financially dependent on you, such as a minor or a severely disabled adult, as they can successfully challenge your will in court.

Drafting a last will and testament gives you the freedom to choose exactly who will benefit from your life’s work. In most cases, parents wish to leave their estate equally to their children. However, family dynamics can be complicated. Estrangement, past financial gifts, or severe behavioural issues sometimes lead a parent to consider disinheriting a child. If you live in Prince Edward Island, it is vital to understand that testamentary freedom-the right to leave your money to whoever you want-is not absolute. The law places clear boundaries on who you can legally cut out of your estate.

The central piece of legislation governing this issue in the province is the Dependants of a Deceased Person Relief Act. This law ensures that individuals who relied on the deceased for daily financial support are not left destitute. Whether you reside in Cornwall, Charlottetown, or Stratford, the Supreme Court of PEI has the authority to completely rewrite your will if it deems you have failed to make adequate provisions for your legal dependants. Navigating this emotional and complex area of law requires immense care and professional guidance.

Step-by-Step Process in Prince Edward Island

If you have made the difficult decision to exclude a child from your estate, you must take proactive, legally sound steps. A simple verbal statement or a badly written note will only guarantee a massive family lawsuit after you pass away.

Step 1: Determine if the Child is a “Dependant”

The very first step is to assess the legal status of the child you wish to disinherit. In PEI, a dependant is generally defined as a child under the age of 18, or an adult child who cannot earn a living due to a severe mental or physical disability. If the child falls into either of these categories, you have a legal obligation to support them, and any attempt to disinherit them will likely be overturned by a judge. Conversely, an able-bodied, financially independent 35-year-old is not a dependant and can generally be excluded from your will.

Step 2: Draft a Clear and Explicit Will

If the child is independent, you must work with a local law firm to draft a rock-solid will . You should not simply “forget” to mention the child in the document, as they could argue it was an oversight. Instead, your lawyer will help you include a specific exclusion clause. This clause acknowledges the child’s existence but explicitly states your intention to leave them nothing. Sometimes, lawyers also advise drafting a separate private memorandum detailing the exact, objective reasons for the disinheritance (such as a total lack of contact for ten years).

Step 3: Consider Alternative Estate Planning Tools

To further protect your estate from a potential court challenge, consider transferring assets outside of your will. Assets held in joint tenancy with right of survivorship, or accounts with designated beneficiaries like life insurance policies, TFSA, and RRSP, bypass the estate entirely. By moving significant wealth into these vehicles, or by utilizing an inter vivos family trust, you minimize the pool of assets that a disgruntled child could potentially claim during probate.

How Much Does it Cost in Prince Edward Island?

Preventing an estate dispute costs a fraction of what your family would pay to fight a lawsuit in the Supreme Court of PEI. Investing in proper legal counsel is essential when dealing with disinheritance.

Service / ExpenseEstimated Cost (CAD)
Complex Will Drafting & Consultation$800 – $1,500+
Setting Up Alternative Trusts$2,500 – $5,000
Estate Litigation (If challenged)$10,000 – $50,000+ per party

How Long Does the Process Take?

Drafting a specialized will that excludes a family member typically takes 2 to 4 weeks, as it requires deeper discussion and careful wording. However, if your estate plan is eventually challenged by the disinherited child after your death under the Dependants of a Deceased Person Relief Act, the ensuing litigation process in the Supreme Court of PEI can drag on for 2 to 5 years, freezing the distribution of your assets to your intended beneficiaries during that entire time.

Frequently Asked Questions (FAQ)

Can an independent adult child successfully challenge my will in PEI?

While they can theoretically attempt to challenge the will based on lack of mental capacity or undue influence, independent adult children generally do not have the right to claim dependant relief. If the will is drafted correctly, their chances of success are very low.

Does leaving a child $1 prevent them from suing the estate?

No, this is a very common legal myth. Leaving a token amount like $1 CAD does not prevent a dependant child from filing a claim for adequate support, nor does it stop an independent child from challenging the overall validity of the document.

Can I disinherit my legally married spouse in Prince Edward Island?

Generally, no. Under provincial family law and the Dependants Relief Act, a surviving spouse has significant legal rights to property and ongoing support. Attempts to completely disinherit a spouse almost always result in successful court intervention.

Are stepchildren considered dependants under PEI law?

A stepchild can be considered a dependant if the deceased parent actively acted as their parent (stood in the place of a parent) and provided them with ongoing financial support immediately prior to death.

Should I explain why I am disinheriting the child in the will?

Lawyers often advise against putting long, emotional grievances directly into the public will. Instead, you can state the exclusion plainly and keep a separate, private statutory declaration with your lawyer detailing the objective reasons for your decision.
