The short answer: Property documents from Ukrainian registers and notarial archives can be obtained while you stay in Canada. Fresh extracts from the State Register of Property Rights, duplicate title documents, and notarized copies are pulled by a representative acting under your authority. The main caveat: some documents are issued only to the owner personally, so the representative's authority has to be documented first.
This usually comes up when a Canadian bank, a lawyer, an estate file, or a buyer asks for proof of what you own in Ukraine. The documents themselves are straightforward once the request is correct; the chain around them — the power of attorney, the apostille if the document travels to Canada, the translation — is where the planning sits.
