The vendor must be able to prove they have "clean" title in order to sell the property. This means that anyone with an interest in the property under Greek inheritance laws, must also agree to sell. A typical situation is where a rich brother says "No", when the other brothers and sisters have agreed - in which case the property cannot be sold until negotiations change the situation.

The vendor may or may not have a formal title deed. Often with older properties, it is legally deemed that the vendor has title after using the property for a number of years. The vendor will need to provide documents to confirm this.

The property, vendor and the purchaser must be free of any tax debts, such as tax arrears due to previous under-declaration of property size. The vendor and the purchaser must be registered for Greek taxes before the purchase can proceed.
