Eliza PerronPrincess Margriet of the Netherlands is trending in Canada this week — and with good reason. The Dutch royal, now 82, holds a unique distinction: she is the only member of the Dutch royal family born on Canadian soil, delivered at the Ottawa Civic Hospital on January 19, 1943, while her mother Queen Juliana was in exile during the Second World War. The Canadian government, in a gesture of diplomatic solidarity, temporarily declared the maternity ward extraterritorial so that the princess would be born on Dutch soil and retain her royal succession rights.
That 83-year-old legal manoeuvre is a striking reminder that nationality, inheritance, and succession law can intersect in ways that require careful planning — and that moment is now drawing renewed attention as Canadians with international family ties examine their own estate situations.
The Ottawa Civic Hospital Manoeuvre: A Legal Precedent Still Relevant Today
The 1943 arrangement — in which Canadian Parliament passed a special resolution declaring the maternity ward outside Canadian jurisdiction — was not just royal ceremony. It was a substantive legal act designed to protect Princess Margriet's place in the Dutch line of succession. Under Dutch constitutional law at the time, a prince or princess born on foreign soil risked complications in their standing.
Canadian estate lawyers flag this story regularly when clients ask about children born abroad, assets held in multiple jurisdictions, or the inheritance rights of family members living in different countries.
"Most Canadians don't realise that succession law varies significantly across provinces and between countries," says a Toronto-based wills and estates lawyer. "If you have family in the Netherlands, the UK, or elsewhere — or assets there — the rules are different, and a single Canadian will may not be sufficient."
What Cross-Border Estate Planning Actually Involves
Canada does not have a federal inheritance tax, but Canadians with assets or beneficiaries in other jurisdictions often discover that the destination country has estate or inheritance taxes of its own. The Netherlands, for example, applies inheritance tax (erfbelasting) on assets received from Dutch residents, with rates ranging from 10% to 40% depending on the relationship and the asset value. The Dutch Tax and Customs Administration publishes current rates and thresholds at belastingdienst.nl.
For Canadians with Dutch family members, real estate in Europe, or accounts in jurisdictions with active inheritance tax regimes, this matters directly.
Key areas where cross-border estate planning applies:
1. Wills and their international recognition
A Canadian will may or may not be automatically recognised in a foreign jurisdiction. Many countries require that a will comply with their own formal requirements (notarization, witnesses, specific language) to take effect on locally-held assets. Some European countries, under the EU Succession Regulation (Brussels IV), allow citizens to elect the law of their nationality or habitual residence to govern their estate — a choice that must be made explicitly and documented carefully.
2. Jointly held property and survivorship rights
In Canada, spouses often hold property as joint tenants, meaning the surviving spouse automatically inherits the property regardless of what the will says. This automatic transfer is not universal. In many civil law countries (France, Belgium, the Netherlands, Quebec), the rules differ — surviving rights may be limited, and forced heirship rules may require a share to pass to children whether or not the deceased wished it.
3. Beneficiaries with dual citizenship or foreign residency
If you name a beneficiary who lives in another country, their receipt of your estate may trigger tax obligations in their country of residence. A lump-sum inheritance from a Canadian parent can generate significant tax liabilities for a child living in a jurisdiction with active inheritance taxes.
4. Life insurance and registered accounts (RRSP/TFSA)
Canadian registered accounts do not exist in most other countries' tax frameworks. A designated beneficiary receiving RRSP funds from a Canadian parent may face unexpected tax treatment in their country of residence on what Canadians consider a tax-deferred vehicle.
The Princess Margriet Parallel for Ordinary Families
Princess Margriet's story is extraordinary — a temporary legislative act to protect a royal's succession rights. But the underlying legal challenge it solved is ordinary: people move across borders, marry across borders, hold assets across borders, and raise families across borders. The succession question — who inherits what, under which law, taxed by whom — doesn't resolve itself.
For the estimated 1.2 million Canadians who were born in the Netherlands, or who have immediate family members currently residing there (Canada-Netherlands migration has historically been among the strongest European immigration flows to Canada), this is not an academic question.
It applies equally to Canadian families with ties to Germany, France, Italy, the UK, or any other jurisdiction with distinct inheritance rules.
When to Seek Expert Advice
Estate planning with international dimensions is a specialised field that sits at the intersection of tax law, family law, and international private law. Generalist lawyers, however skilled, may not have the cross-border fluency required.
Expert Zoom connects you with wills and estates lawyers experienced in cross-border estate planning who can advise on multi-jurisdiction will structures, international tax exposure, and the coordination of estate documents across legal systems.
If you have assets outside Canada, a beneficiary living abroad, dual citizenship, or family ties to a country with inheritance tax — the time to plan is before a succession event, not during one. A 1943 act of Parliament helped Princess Margriet inherit her crown. For most Canadians, a well-drafted will and a qualified estate lawyer will do the job.
