A contractual prohibition on encumbrance and sale is a restriction created by agreement. The owner undertakes not to sell or encumber the property without the consent of a beneficiary. It often serves to secure interests within the family, for example when parents transfer a property and reserve control over later dispositions.
The statutory basis is found in section 364c of the Austrian Civil Code. Such a prohibition operates against third parties, and is therefore effective in rem, only if it is registered in the land register and was created between close relatives. The law names a specific circle, for example spouses, registered partners, parents and children. Outside this circle, an agreed prohibition only operates between the contracting parties and does not block the sale against third parties.
If the prohibition is effectively registered, the owner cannot validly sell the property alone. The buyer only acquires ownership once the beneficiary consents or the prohibition is deleted. We explain the individual terms in the entry on the prohibition on encumbrance and sale.
