Fellesgjeld
Fellesgjeld (shared debt) is the part of a borettslag (housing cooperative) or housing joint-stock company's total borrowing that finances common assets: the buildings, the site, parking facilities and communal areas. As a share owner you do not own the flat itself, but a share in the cooperative, and you service your part of the fellesgjeld through the monthly felleskostnader (common charges). In practice the fellesgjeld is therefore a personal payment obligation, even though the loan legally sits with the cooperative.
The legal basis is burettslagslova (the Housing Cooperatives Act), in particular section 5-19 on felleskostnader and section 5-20 on legalpant (statutory lien) for unpaid claims. The loan is secured by a charge over the borettslag's property, not over the individual share. This means the share owner can pay down their part through the common charges, but cannot demand that it be discharged or refinanced individually; refinancing must happen at cooperative level, following a resolution by the general meeting.
The share of fellesgjeld and the monthly repayment are stated in the sales prospectus and in the adkomstdokumenter (share transfer documents). The total purchase price consists of two components: the deposit (what you pay in cash or with your own loan) and the share of fellesgjeld. These two add up to the total price, which is the real purchase amount for the home. A flat advertised at 3 million in deposit with 2 million in share of fellesgjeld therefore costs 5 million as a total price. The difference is not cosmetic: interest on fellesgjeld cannot be deducted on the share owner's tax return, because the cooperative is the borrower. The tax deduction goes to the cooperative, and the effect comes indirectly through lower felleskostnader. This is a recurring misunderstanding when buying an andelsleilighet (cooperative flat).
Many borettslag have an interest-only period on the fellesgjeld, typically five to ten years, before repayments start. When the interest-only period ends, the common charges rise noticeably. This is often called the "fellesgjeld bomb" and is a well-known risk for buyers of newer cooperative flats. Check the loan terms in the prospectus: repayment period, interest-only period, interest terms (fixed or floating), and whether the cooperative has entered into an interest rate swap. A cooperative with 30 yr repayment and a fixed rate for 10 yr gives very different future felleskostnader than a cooperative with a floating rate and a short horizon.
Borettslag have a special security for unpaid felleskostnader: a legalpant of up to 2 G on the individual share under burettslagslova section 5-20, without registration. That lets the cooperative petition for a forced sale of a defaulting share relatively quickly. The fellesgjeld itself is secured by a charge over the cooperative's property, and the individual share owner is not normally personally liable for other share owners' debt. The exception is joint and several liability in smaller boligbyggelag (housing construction cooperatives) and borettslag formed before 2005, where older articles of association may apply. In modern cooperatives the liability follows the share and ends on sale.
In Placepoint you can see registered charges on the borettslag's property in the property panel. The individual share's part of the fellesgjeld and the monthly felleskostnader are usually taken from the prospectus and the managing agent's key figures, not from Grunnboken.

Frequently asked questions
What is the difference between the deposit and the fellesgjeld?
The deposit is the part the buyer pays themselves (in cash or with their own bank loan) when buying a borettslag share. Fellesgjeld is the share's part of the borettslag's total borrowing, which is serviced through the felleskostnader. Together they make up the total price.
Do I get a tax deduction for the interest on the fellesgjeld?
No. The loan sits with the borettslag as a legal person, and the interest deduction goes to the cooperative. The effect comes indirectly through lower felleskostnader. Interest on your own deposit loan can, however, be deducted on your tax return as normal.
What is a "fellesgjeld bomb"?
Many borettslag have an interest-only period on the fellesgjeld of 5 to 10 years. When the interest-only period ends, the monthly felleskostnader rise substantially. This is popularly called a fellesgjeld bomb and is a well-known risk when buying newer cooperative flats.
Where do I find the share of fellesgjeld for a specific flat?
In the prospectus, the adkomstdokumenter and with the managing agent. For a resale purchase, the estate agent must state the share of fellesgjeld, the monthly servicing amount and the loan terms in the sales particulars.
What happens to the fellesgjeld when the share is sold?
It follows the share to the new owner. The seller is released from their part of the fellesgjeld on transfer, and the buyer takes over the servicing through the common charges. The change of ownership is registered in Borettsregisteret at Kartverket.
