Köpekontrakt
Köpekontrakt is the binding purchase agreement used when a fastighet (a Swedish property unit) is sold in Sweden. It is the document that sets the purchase price, the takeover date and any conditions, and that the seller and the buyer sign at the contract meeting, usually together with the mäklaren (the estate agent).
The rules for what makes a property purchase valid are set out in jordabalken 4 kap. 1 § (the Swedish land code). The contract must be in writing, signed by both the seller and the buyer, state which fastighet the sale concerns, give the purchase price, and contain the seller's declaration that the property is transferred to the buyer. If one of these five elements is missing, the agreement is invalid, not merely incomplete, and an oral side agreement about the same purchase has no legal effect alongside the written one.
The Swedish system uses two documents where Norway uses one. The köpekontrakt is the binding agreement entered into first, often with handpenning (the deposit) paid at the same time. The köpebrev comes later, once the buyer has paid the full purchase price, and works as a receipt confirming that payment is complete. It is the köpebrev, not the köpekontrakt, that is the fångeshandling (the document of acquisition) the buyer encloses with the application for lagfart at Lantmäteriet. The reason is that the köpekontrakt often contains conditions and details the parties do not want made public, while documents sent to Lantmäteriet become publicly available through the fastighetsregistret.
The contract often contains a svävarvillkor, a suspensive condition that makes the sale dependent on something not yet settled, most often that the buyer is granted a loan within an agreed deadline. Under jordabalken 4 kap. 4 §, such a condition cannot run for longer than two years from the contract date. If a longer deadline is agreed, the entire purchase falls away, not just the condition. If the condition is not met within the deadline, the sale is reversed: the seller keeps the fastighet, and the buyer gets the handpenning back.
The Norwegian counterpart is the kjøpekontrakt combined with the skjøte (the deed), but the comparison breaks down on one point. A Norwegian kjøpekontrakt is a private agreement between the parties and is never registered; it is the skjøte alone that transfers hjemmel (legal title) and is registered in Grunnboken, usually at the same time as settlement is completed through the estate agent's client account. Sweden instead uses two documents one after the other, where the second, the köpebrev, both confirms completed settlement and opens the way for the lagfart application. Norway has no equivalent two-step process between the contract and the transfer of title.
A bostadsrätt is not sold with a köpekontrakt in this sense. The transfer follows bostadsrättslagen, not jordabalken, and never gives lagfart, because it is the share in the association that changes owner, not a fastighet.
If a mäklare is involved, they must draw up and go through the contract documents with both parties at a personal meeting, unless the parties have agreed otherwise. In a private sale without a mäklare, the same formal requirements in jordabalken apply, only without this quality check. For now, the köpekontrakt cannot be signed electronically either: jordabalken 4 kap. 1 § requires a signature on paper, unlike the Norwegian skjøte, which has been registered electronically for professional users since 2017.
