Can a Russian owner sell and receive the proceeds?

The sale itself runs like for any owner, through notary and register — including by power of attorney without travelling. The real question is receiving the proceeds: whether and to which account a bank pays out depends on the origin of funds, the account country and the applicable EU payment rules, and is examined case by case. Plan the payment route BEFORE notarisation — Svetlana aligns it with bank and notary before any costs arise.
