The short answer: The estate of a relative who died in Ukraine can be administered while you stay in Canada. The first hard fact is the six-month window from the date of death for accepting the inheritance, and acceptance can be filed by a representative under a power of attorney. The main caveat: nearly every later step — property, accounts, sale, transfer — flows from the notarial case opened in that window, so starting early is what keeps options open.
In practice this begins as logistics under grief, from another continent: the death certificate, the inheritance case at a notary, relatives informing each other, and decisions about funeral and property matters that cannot all wait. Structured early — representative appointed, documents moving, deadline protected — the estate proceeds in order. Left loose, it turns into the court route and lost accounts.
