Can a Cousin Sell Inherited Property in Greece Without My Permission?

No. Under Greek inheritance law, when multiple heirs inherit a property together, each holds an undivided share of the whole. No single co-owner can sell, rent, or make major decisions about the property without the agreement of all co-owners. Your cousin cannot legally sell the entire property without your consent, and any attempt to do so is not a valid transfer.

How Co-Ownership Works in Greek Inheritance

When a property passes to multiple heirs, whether through a will or intestate succession, each heir becomes a co-owner of an undivided percentage of the whole property. This is not ownership of a specific room or floor. It is a fractional legal interest in the entire property. Every major decision about that property, including selling, mortgaging, renting, or renovating, requires the agreement of all co-owners. No heir can make major decisions such as selling without the consent of the others.

What a Cousin Can Do Without Your Permission

While your cousin cannot sell the whole property, they can legally sell or transfer their own individual share to a third party without your consent. This is an important distinction. If your cousin sells their share to an outside buyer, you now have a new co-owner you did not choose and may have never met. That buyer holds your cousin's percentage of the property and has the same co-ownership rights your cousin had. This is legal under Greek law and is one of the most unsettling outcomes in co-ownership disputes.

What Cannot Happen to Your Share

Your share of the property cannot be sold, transferred, or encumbered by anyone other than you. It belongs to you as a legal heir and cannot be disposed of without your involvement. However if you have never formally registered your share in the Greek land registry, your legal interest exists but is not visible in the official records. This creates practical risk even if your legal right is technically intact.

What Happens When Co-Owners Disagree

Co-ownership disputes are one of the most common and most difficult situations in Greek inheritance law. If your cousin wants to sell and you do not, or vice versa, neither of you can force the other to sign a sale contract. The property can become paralyzed for years with nobody able to make decisions about it.

There are two ways out of this deadlock under Greek law. The first is mediation, where the co-owners reach a negotiated agreement about what to do with the property, whether that means one heir buying out the other, agreeing to sell to a third party, or dividing the property if it can physically be divided. The second is a court partition action, known in Greek as agogi dianomis, where a co-owner asks the court to force a division or sale of the property and distribute the proceeds according to each heir's share. This is a legitimate but slow and costly process that can take years to resolve.

Why Acting Now Matters

The longer a co-ownership dispute sits unresolved, the more complicated and expensive it becomes. ENFIA accumulates on the property every year regardless of who is managing it or whether anyone is using it. Under Greece's new orphaned estate framework, properties with unclear or inactive ownership records are increasingly at risk of being flagged. And under the 2026 inheritance law reform, the rules around co-ownership and forced heirship have changed in ways that affect how disputes are resolved going forward.
