Estate planning after separation

Your will still says
their name.

Separation is one of the most important times to update your estate plan. Whether you are in Canada or the US, your will, beneficiaries, and powers of attorney need to reflect your new reality.

Why this matters

Beneficiary designations
override your will.

A will only controls what is in your estate. Financial accounts with named beneficiaries pass directly to that person, outside your estate entirely. If your former spouse is still named, they may receive those assets regardless of what your will says.

⚠️

This is not theoretical

Courts in both Canada and the US have upheld beneficiary designations in favor of former spouses when the account holder failed to update them after separation. Even a completed, signed separation agreement is not enough. Each financial institution requires its own written change of beneficiary form.

🏦

RRSPs, RRIFs, 401(k)s and IRAs

A named beneficiary on any registered or tax-advantaged account bypasses your will and your estate entirely. The funds transfer directly. Updating your will does nothing here.

Must be changed directly with your financial institution.
πŸ’°

TFSAs and Roth IRAs

In Canada, a TFSA successor holder or beneficiary designation transfers the account outside your estate. In the US, Roth IRA beneficiary designations work the same way. Both require updating separately with the financial institution.

Check all tax-advantaged accounts, not just the obvious ones.
πŸ›‘οΈ

Life insurance

Group life through your employer and personal policies each have beneficiary designations. If your former spouse is named, they receive the payout. Your HR department and your insurer both need a written change request.

Check employer group plans separately from personal policies.
What needs updating

The full list.
In order of urgency.

Start with beneficiary designations, because those are the ones that bypass your will. Then update your will, then your powers of attorney.

1

RRSP, RRIF, and TFSA beneficiaries (Canada) / 401(k), IRA, and Roth IRA beneficiaries (US)

Contact each financial institution directly. You will need to complete a Change of Beneficiary form. Some institutions require it notarised or witnessed.

2

Life insurance policies

Personal policies through your broker or insurer, and group benefits through your employer. Two separate processes, often two separate forms.

3

Your will

Update the distribution of your estate, named executor, and any specific bequests. If you have children, guardianship designations need particular care.

4

Power of attorney for property (Canada) / Durable power of attorney (US)

Who makes financial decisions if you are incapacitated? If your former spouse is named, that needs to change. The document name varies by province or state, but the function is the same.

5

Power of attorney for personal care (Canada) / Healthcare proxy or medical power of attorney (US)

Who makes medical decisions on your behalf? This is separate from property and equally important to update. The name differs by province or state, but the purpose is the same.

6

Guardianship designations for children

If both parents die, who would care for your children? This designation in your will matters, particularly when the co-parenting relationship is complex.

Quebec: different rules apply

Quebec operates under civil law. Wills in Quebec must be notarial (prepared and authenticated by a notary) to be automatically searchable in the Registre des testaments. Holograph wills and wills made in the presence of witnesses are valid but must be probated.

Separation and divorce in Quebec also affect testamentary dispositions differently. If you were married in Quebec, divorce revokes legacy provisions in favor of a former spouse under Article 764 of the Civil Code. Separation without divorce does not have the same automatic effect.

Quebec residents: work with a notary for will preparation. Online will tools can be a starting point, but for a notarial will you will need a Quebec notary. Use FairWell's directory to find one.

When should you do this?

As soon as possible after separating. You do not need to wait for a divorce order. Many people update estate documents at the same time as they finalise their separation agreement. Some people do it earlier, which is entirely reasonable.

If you die without a will, or with an outdated one, your province or state's intestacy rules apply. In most Canadian provinces and many US states, a separated but not yet divorced spouse still has inheritance rights.

Common questions

Estate planning
after separation.

For most people with straightforward estates, no. Online platforms can produce legally valid wills in most provinces and states. You typically need two witnesses to sign (who are not beneficiaries), which you arrange yourself. If your estate is complex, particularly if you own a business, have significant assets, or have children from multiple relationships, working with an estate lawyer is the better choice.
Then your province or state's intestacy laws determine who receives your estate and who cares for your children. In many places, a separated but not yet divorced spouse may still have a claim on your estate. Your children would typically receive the remainder in equal shares, held in trust if they are minors. The court appoints an administrator. This process is slower, more expensive, and gives you no control over the outcome. Making a will now is one of the most important things you can do for your children.
No. In most Canadian provinces and US states, a separation agreement has no automatic effect on a previously made will. Divorce does revoke gifts and executor appointments in favor of a former spouse under many succession laws, but separation without divorce typically does not. You need to make a new will, or a formal codicil amending your existing one.
As soon as practicable. There is no legal deadline, but the risk is real from the day you separate. If something happened to you tomorrow with an outdated will and unchanged beneficiary designations, your former spouse could receive significant assets intended for your children or other family members. Most people prioritise this in the first month after separation, alongside or just after their separation agreement.
You can, but if your children are minors, the funds generally cannot be paid to them directly. They would be held by a court-appointed guardian until the children reach adulthood, which varies by province or state. A better approach for most parents is to name your estate as the beneficiary and direct those funds through your will into a testamentary trust for your children's benefit. Speak to an estate lawyer or financial planner if you want to structure this properly.
A power of attorney (or, in many US states, a durable power of attorney or healthcare proxy) authorises someone to act on your behalf. One document covers financial decisions if you become incapacitated; another covers medical and lifestyle decisions. If you do not have either, a court would need to appoint a guardian, which is expensive and slow. If your former spouse is currently named, that needs updating immediately.
