When an aging parent forms a new relationship and begins changing their will or financial plans, adult children face a difficult legal situation. Here's what BC law says and what you can do.
It's a scenario that family lawyers see: a widowed or divorced parent meets a new partner later in life, and within months — sometimes weeks — they're making changes to their will, transferring assets, or signing new powers of attorney. For adult children, this can feel alarming. In some cases, it is alarming. In others, the parent is simply exercising their right to make their own choices.
Telling the difference — and knowing what you can do — is what this guide is about.
The Legal Right to Change a Will
Let's start with the hard truth: as long as your parent has capacity and is not being unduly influenced, they have the absolute right to change their will, give away their assets, and choose whoever they want as their power of attorney — including a new partner. Adult children have no legal entitlement to inherit, and a parent is not required to treat children equally or explain their decisions.
This is a feature, not a flaw, of BC's estate law. It protects the autonomy of older adults to make their own choices.
When It Becomes a Legal Problem: Undue Influence
The line is crossed when the new partner uses pressure, manipulation, isolation, or deception to influence your parent's decisions. This is called undue influence, and it can make legal documents — including wills and powers of attorney — voidable in BC courts.
Undue influence doesn't require shouting or threats. It can be subtle: controlling access to family members, making a parent financially dependent, persuading them that children "don't care," or simply being ever-present while gradually reshaping a parent's views. Courts look at the totality of the relationship and circumstances.
Signs That May Indicate a Problem
- Your parent is increasingly isolated from family and longtime friends
- The new partner is always present, even at medical or legal appointments
- Your parent seems confused, fearful, or reluctant to speak freely
- Documents were changed very quickly after the relationship began
- Changes benefit the new partner exclusively, at the expense of family who was previously included
- Your parent can't clearly explain why they made the changes when asked in private
None of these signs is conclusive on its own — but a pattern is worth taking seriously.
Steps You Can Take
*Try to speak with your parent privately.* If possible, find a time when the new partner isn't present. Ask open-ended questions about how they're doing, whether they feel happy with the decisions they've been making, and whether anyone has been pressuring them. Don't lead or accuse — just listen.
*Contact their doctor.* If you have concerns about capacity — whether your parent fully understands the implications of the changes they've made — you can contact their GP and share your observations. The doctor cannot share medical information with you without consent, but they can receive information from you and factor it into their assessments.
*Consult a lawyer.* A lawyer with estate litigation experience can review the circumstances, advise you on whether there are grounds to challenge documents, and send a letter to the new partner or their lawyer if appropriate. Sometimes, early legal involvement changes behaviour without requiring litigation.
*Gather evidence.* Document your observations — dates, what was said, who was present. Save any communications from your parent that seem unusual. If other family members share your concerns, coordinate and document their observations too. This evidence matters if litigation becomes necessary.
Challenging a Will or Power of Attorney in BC
If your parent changes their will under undue influence and then dies, you can challenge the will in BC court. The burden of proof shifts in some circumstances — particularly where a relationship of trust and dependency existed. A successful challenge can restore an earlier will or result in the estate being distributed under intestacy rules.
You can also challenge a power of attorney if you believe it was granted under undue influence or without proper capacity.
WESA also allows spouses and children to bring a claim against a will that fails to make adequate provision for them — regardless of undue influence — which provides an additional avenue in some cases.
Acting Early Matters
Courts have overturned wills and powers of attorney based on undue influence, but the process is expensive and emotionally exhausting. Acting early — while your parent is still alive and changes can potentially be addressed — is almost always better than litigation after they're gone.
If you're concerned, a consultation with an estate lawyer sooner rather than later is the right move.
Not if your parent has capacity and is acting freely. Adults have the right to change their will at any time for any reason. However, if you believe the change was made under undue influence or without proper capacity, you may be able to challenge it in court — either while your parent is alive or after they die.
Undue influence occurs when someone uses pressure, manipulation, deception, or control to override a person's free will in making legal decisions — like a will or power of attorney. It doesn't require threats; subtle isolation and emotional manipulation can qualify. Courts look at the full picture of the relationship.
Yes. If you have evidence of undue influence or lack of capacity, you can bring an estate litigation claim in BC Supreme Court after your parent's death. Time limits apply, so consulting a lawyer promptly after the death is important.
BC's Wills, Estates and Succession Act allows spouses and children to apply to court to vary a will that fails to make adequate provision for their proper maintenance and support. This is separate from undue influence and provides an additional legal avenue for family members left out of a will.
