Kinnisasja

Kinnisasja is a Finnish legal term referring to immovable property under Finnish property law. It denotes land and buildings, together with any fixtures permanently attached to the land, treated as a single legal unit. A kinnisasja is a unit in the real estate register and is identified by a cadastral number and a legal description. Rights in a kinnisasja—such as ownership, usufructs, easements, and mortgages—are attached to the property itself rather than to a person. Because of this, transfers of ownership involve updating the register entry for the kinnisasja.

In the Finnish system, a mortgage or other encumbrance is recorded against the kinnisasja, creating a lien on the property that may have priority over other claims. This structure ensures that creditors may claim the value of the kinnisasja if the debtor defaults, subject to statutory priorities and protections. The term is used in land and property transactions, urban planning, and tax administration, and it plays a central role in determining who can use or develop a parcel of land.

Kinnisasja is distinguished from movable property, which can be transported and is not registered in the real estate register. The management and registration of kinnisasja rights are handled within Finland by the land survey authority (Maanmittauslaitos) and the real estate register (Kiinteistörekisteri).
