Property still registered in a dead person's name
Immovable property in Cyprus is recorded in a register kept by the Department of Lands and Surveys (Τμήμα Κτηματολογίου και Χωρομετρίας). The register records the person in whose name each parcel stands. It is that entry, and not a will, a family understanding or a payment of tax, which determines what the state treats as ownership.
A death does not alter the register by itself. Until something is done, the entry continues to name the person who died, sometimes for decades. Families abroad frequently discover this only when they try to do something with the property: sell it, mortgage it, allow a relative to build on it, or divide it among themselves. Nothing can be done with it in that state, and the first honest answer to "can we sell it" is usually "not yet".
The work involved is not, in most cases, a dispute. It is a sequence of steps, in a fixed order, most of which produce a document. The difficulty for a family in London or Melbourne is that each step involves a Cypriot institution, in Greek, in a district they may never have visited.
What to send us in a first enquiry
The name of the person who died, as it appears on Cypriot documents, the date and place of death, the village or district, the names of the surviving family, and anything you hold in writing. If all you have is a village name and a memory of a field, that is a starting point we work from regularly.
