When a secured property loan defaults, the investor's claim leaves the world of negotiation and enters a procedure. In Switzerland that procedure lives in the Debt Enforcement and Bankruptcy Act, the DEBA (in German, the SchKG): the holder of a registered mortgage petitions for the pledged property to be realised, the sale runs under official supervision, normally as a public auction, and the proceeds are distributed to creditors in the order their security sits in the land register. Everything that decides recovery on that day, the rank, the paperwork, the cushion of value, was fixed years earlier when the loan was made. This piece walks through the machinery, and what it rewards.
Default is defined before it happens
A loan doesn't default by atmosphere; it defaults against a list. The facility agreement names the events, a missed payment, a breached covenant, an insolvency filing, and names what the investor may do when one occurs. Well-run lending pairs that list with monitoring, so a deteriorating file is noticed early; in our own nine-step process, ongoing monitoring with defined enforcement triggers is the final step and runs for the life of the loan.
The statute behind all of this is live, maintained machinery. A revision of the SchKG took effect on 1 January 2025: among the changes, creditors now have 20 days rather than 10 to request the continuation of a bankruptcy that would otherwise halt for lack of assets, and unpaid public claims such as taxes can now lead directly to bankruptcy rather than only to attachment. The revision changes little in an investor's day-to-day position, though it shows that enforcement law keeps moving and has to be read again from time to time.
The sale runs through an office, never through self-help
Swiss law does not let an investor collect the keys. Realisation of pledged real estate runs through official proceedings, and the default route ends in a public auction conducted under the DEBA. Parties can in principle agree private realisation in advance, which tends to be faster, yet for real estate the option is largely theoretical: as Bär & Karrer note in the 2026 ICLG lending chapter for Switzerland, a private-sale right would have to sit in a notarised security agreement, a step rarely taken in practice.
Bankruptcy narrows the road further. Once proceedings open, pledged assets fall into the estate and are realised by the bankruptcy administrator; private enforcement of estate assets is not permitted at all. The secured creditor keeps a strong position inside the process rather than outside it: secured claims are paid from the collateral's proceeds with preference, interest accruing up to realisation is honoured where the proceeds suffice, and claims secured by a mortgage on real estate are the standing exception to the rule that bankruptcy accelerates every debt.
The register sets the payout order
Distribution follows a fixed sequence. The costs of the enforcement come out first. Secured creditors are then paid in the order of their registered rank, which is why the two words "first rank" carry the weight they do; we set out how that queue forms in the first-rank explainer. Whatever remains flows to unsecured creditors, who in practice often recover little.
Auctions are honest but unsentimental. A forced sale can clear below what a willing seller would achieve, and the gap between the loan and the property's value is what absorbs that discount, together with the costs and the accrued interest. This is the day the loan-to-value ratio was underwritten for, a point we take further in the loan-to-value explainer.
Where the proceeds still fall short, the claim survives. The unpaid remainder continues against the borrower as an unsecured debt, and where a personal guarantee stands behind the loan the investor can pursue the guarantor's estate for the gap, the mechanism covered in the personal-guarantee explainer.
Where Watson AM fits
Enforcement is the part of a security package everyone hopes never to use, and we prepare files to that standard regardless, because what security is worth is decided by how it would perform inside the procedure described above. On each of our twelve published case files, a first-rank mortgage was entered at notarial registration, step six of our nine-step diligence, as a condition of the investors' funding, so the queue position existed from the first day; a personal guarantee stands behind it; and monitoring with defined enforcement triggers runs for the life of the facility.
Seen that way, an explainer about auctions is also an explainer about origination. Rank, valuation and paperwork are all settled when a loan is made, and a file assessed as though the auction might one day happen is one whose investors already know what they would recover if it did. Investor and borrower material is available on request.
Common questions
Can an investor simply take the property when a borrower defaults?
No. Swiss law channels the realisation of pledged real estate through official debt-enforcement proceedings, normally ending in a supervised public auction. Private realisation of real estate is generally unavailable in practice because the security agreement would need to be notarised, a step rarely taken, and once bankruptcy is opened, private enforcement of pledged assets in the estate is not permitted at all.
Who is paid first when a mortgaged property is sold in enforcement?
The costs of the enforcement come out of the proceeds first. Secured creditors are then paid in the order of their registered rank, so a first-rank mortgage holder stands ahead of every junior charge. Whatever remains after the secured claims flows to unsecured creditors.
What happens if the sale does not cover the loan?
The shortfall survives as an unsecured claim against the borrower. Where a personal guarantee stands behind the loan, the investor can also pursue the guarantor for the gap, which is one of the reasons investors take a guarantee alongside a registered mortgage.
