Can I sell without travelling to Bulgaria?

Yes. The usual route is a notarised power of attorney to a trusted person or lawyer: you execute it either at the Bulgarian mission in your country or before a local notary with apostille and certified translation. The notary in Bulgaria verifies the power of attorney before the deed. Svetlana organises the chain of power of attorney, documents and payment route — especially for owners who can no longer or do not wish to travel.
