You are launching a business, signing a lease or hiring your first employee. Alongside future sales and expenses, ask one question before committing: if the business cannot pay, could creditors claim the money from you personally?
In Switzerland, the answer starts with your legal structure. A sole proprietor is directly liable, while an LLC (Sàrl/GmbH) or company limited by shares (SA/AG) owns its own assets. Yet forming a company does not protect your private property against every risk: a personal guarantee or a breach of your duties as a director can still expose you.
This guide distinguishes those situations, with examples showing what is at stake and what to check before signing.
Key points
- As a sole proprietor, business debts are personal debts. Your attachable private assets may be at risk.
- In a general partnership, partners have personal, joint and several liability once the legal conditions for pursuing them are met.
- In an LLC or SA, the company is liable with all its assets. Registered share capital does not cap its liability.
- Ownership, management and guaranteeing a debt are three separate roles. You may lose your investment without owing the company’s debts, or become liable under a separate undertaking.
Who is liable for business debts in Switzerland?
Start by checking who entered into the obligation. If your LLC contracts with a supplier and you validly sign on its behalf, the debt belongs to the company. Signing as its representative does not, by itself, mean you personally guarantee payment. A surety clause or signature as a co-debtor can change that position.
The table summarises the starting rule. Personal guarantees and directors’ liability, discussed below, require separate consideration.
| Legal structure | Which assets are liable? | What to watch |
|---|---|---|
| Sole proprietorship | The owner’s attachable business and private assets. | A separate bank account creates no legal protection. |
| General partnership (SNC/Kollektivgesellschaft) | Partnership assets and, subsidiarily, partners’ assets. | Joint and several liability can expose one partner to the entire debt. |
| LLC (Sàrl/GmbH) | Company assets, generally without recourse against a member merely because they own interests. | Check additional contributions required by the articles. |
| Company limited by shares (SA/AG) | Company assets, generally without recourse against a shareholder merely because they own shares. | Subscribed but unpaid share capital remains payable. |
Share capital and company assets are different figures
Share capital is the amount recorded in the articles and commercial register. Assets are what the company actually owns: cash, receivables, equipment, inventory or property. They change as the business trades.
An LLC with CHF 20,000 share capital may therefore own CHF 150,000 of assets. It is liable with all those assets, not just CHF 20,000. Equally, registered capital does not guarantee that the amount remains available in the bank.

Sole proprietorships and partnerships: when private assets are exposed
Sole proprietorship: the owner is personally liable
A Swiss sole proprietorship is not legally separate from its owner. You trade in your own name. An unpaid business invoice can therefore lead a creditor to pursue your attachable private assets, even if you carefully separate expenditure into a business bank account.
Suppose the business owes a supplier CHF 35,000 but has only CHF 4,000 in its account. The remaining CHF 31,000 does not disappear because business cash has run out. Other assets owned by the entrepreneur may be affected by debt enforcement.
This does not mean everything can be seized without limits. Debt enforcement law protects certain essential property and a subsistence minimum when income is attached, particularly under Articles 92 and 93 of the Debt Enforcement and Bankruptcy Act (in French). However, private savings or property do not become untouchable merely because they are not used for business.
Risk therefore depends as much on commitments as on turnover. Even a small operation may have a long lease, credit purchases or substantial potential liability for damage at a customer’s premises. Compare sole proprietorships and LLCs against your actual activities.
General partnership: one partner may owe more than their “share”
Partners in a general partnership have personal, joint and several, subsidiary liability. Joint and several means a creditor may claim the whole amount from one partner, not just the percentage agreed between partners. Subsidiary means the conditions in Article 568 of the Code of Obligations (CO) must be met, notably dissolution of the partnership or unsuccessful enforcement against it.
Imagine two partners sharing costs equally. Once the legal conditions are met, the full CHF 40,000 debt may be claimed from either partner. The person who pays may seek recovery from the other under their internal arrangements, but that offers little comfort if the other cannot repay.
A partnership agreement remains valuable for allocating roles and rights of recourse. It cannot impose a liability limit on creditors who have not agreed to it.
LLCs and limited companies: what separate legal personality protects
Losing an investment is different from owing company debts
LLCs and SAs are legal entities: they own their assets and incur their own debts. This principle appears in Article 620 CO for the SA and Article 772 CO for the LLC. An owner may lose their interest without automatically having to cover the shortfall owed to creditors.
A simple example. Your LLC owes CHF 50,000 but has only CHF 15,000 of realisable assets. The CHF 35,000 shortfall does not automatically become your personal debt. A separate legal basis is needed, such as a valid guarantee or established managing-director liability. This illustrates the separation of assets; actual distributions depend on the procedure and creditors’ rights.
Your loss can nevertheless exceed initial capital. If you invested CHF 20,000 and later lent the company CHF 60,000, you may also fail to recover that loan. Buying interests for CHF 100,000 exposes you to losing that purchase price even if their nominal value is lower.
Amounts the owner may still have to contribute
In an SA with partly paid shares, the unpaid subscription remains due. For example, shares subscribed at their CHF 100,000 nominal value with only CHF 50,000 paid leave CHF 50,000 still payable. Shareholder protection does not remove this obligation.
An LLC’s capital is fully paid on formation. Its articles may nevertheless require additional contributions under Articles 795 and 795a CO. The statutory maximum is twice the nominal value of the interests concerned. An interest of CHF 10,000 may therefore carry an additional obligation of up to CHF 20,000. This is not automatic: read the articles and check when payment can be required.
Does an SA provide more protection than an LLC?
For ordinary business debts, both structures separate company and private assets. An SA does not cancel a personal guarantee or relieve directors of their duties. Financing, new investors and share transfers also matter, as our Swiss LLC versus SA comparison explains.
When can a director be personally liable?
In a small business, one person may own the shares, manage the company and do the daily work. Those roles remain legally distinct. Protection as a member or shareholder does not remove your obligations as a managing director or board member.
A breach of management duties need not involve fraud
Article 754 CO provides for liability for intentional or negligent breaches of duty. Article 827 CO extends it to LLCs. Gross negligence is therefore not required for this civil liability.
However, bankruptcy or an unsuccessful investment does not alone make the director personally liable. Loss, breach of duty, fault and a causal link between the breach and the loss must be established. A project can fail despite diligent decisions.
Problems arise, for example, where management lets finances deteriorate without monitoring them, makes unlawful payments to owners or fails to supervise delegated tasks. Outsourcing bookkeeping to an accountant supports reliable reporting but does not transfer the director’s role.
Cash shortages and overindebtedness: recognise the warning signs
These situations can overlap but are different. A company may own valuable machinery and receivables while lacking cash for this week’s wages. Conversely, a positive bank balance does not prove that all debts are covered.
| Situation | Meaning | What to review |
|---|---|---|
| Imminent insolvency | The company risks being unable to pay debts when due. | Expected receipts, upcoming payments and measures to ensure solvency (Art. 725 CO). |
| Capital loss | Losses have reduced equity beyond the statutory threshold. | The calculation under Article 725a CO and required restructuring measures. |
| Overindebtedness | Assets no longer cover debts using the legally required valuations. | Interim accounts, their audit and whether the court must be notified (Art. 725b CO). |
For the last case, imagine CHF 80,000 of assets against CHF 110,000 of debt: a CHF 30,000 shortfall. In practice, verify valuations and follow the legal procedure; simply subtracting figures on an old balance sheet is insufficient.
Articles 725 to 725b CO require prompt action; Article 820 CO extends these rules to LLCs. Where there are serious grounds to suspect overindebtedness, interim accounts must be prepared and audited. Confirmed overindebtedness generally requires court notification, subject to statutory exceptions. Do not wait for the next annual accounts to act.
A cash flow forecast helps identify difficult payment dates. If the situation is already critical, read our guide to business bankruptcy in Switzerland and promptly obtain advice on the necessary action.
Unpaid AHV/AVS contributions: a specific liability regime
Social insurance contributions require particular attention. Under Article 52 of the Federal Act on Old-Age and Survivors’ Insurance (OASIA), officers of an incorporated employer may be subsidiarily liable for loss caused by intentional breaches or gross negligence. The compensation office must establish those conditions; a late payment does not automatically trigger liability.
Distinguish this gross-negligence threshold from the general rule in Article 754 CO. Part 8 of the Federal Social Insurance Office’s guidelines (in French) explains the regime. Monitor social insurance filings and payments as closely as wages, and address arrears promptly with your accountant and compensation office.
Personal guarantees: the contract matters as much as the structure
A bank agrees to finance your LLC but asks for your personal surety. A landlord offers your SA premises if you also commit personally. The company still has its own assets, but you add a personal obligation alongside its debt.
A suretyship, independent guarantee, co-debtor commitment and pledge of property have different effects. Their validity may also depend on specific formalities. Read the entire clause, not just its heading or the signature page.
Example. You contribute CHF 20,000 to an LLC and personally guarantee a loan up to CHF 50,000. If the undertaking’s conditions are met, you may lose your investment and also have to pay under the guarantee. Its limit and any covered interest or fees depend on the signed document.
Check five points before signing:
- Debt covered: one specific loan, or future commitments too?
- Maximum amount: does it include interest and costs?
- Duration: is there an expiry date or renewal?
- Conditions for a claim: when can the creditor demand payment?
- Release: what happens if you sell your shares or leave management?
Leaving does not automatically release you. On a company sale, obtain the creditor’s written confirmation of any agreed release. An agreement with the buyer does not necessarily remove the bank’s or landlord’s rights against you.
Five ways to limit your exposure
1. Check each signatory’s identity and capacity
Review major contracts: who is the tenant, borrower or purchaser, and in what capacity are you signing? Use the exact company name and respect representation powers. Pre-incorporation contracts need special attention because the future company does not yet exist and its assumption of the contract must be properly arranged.
2. Keep business and personal finances separate
In an LLC or SA, every transfer to your personal account needs a basis: salary, expense reimbursement, a loan or a properly approved dividend. Keep supporting documents and record advances. Our guide to Swiss business accounting explains the fundamentals.
3. Monitor payment dates before they become urgent
Track overdue receivables, wages, social insurance contributions and major upcoming bills. When cash tightens, review more frequently and update forecasts. Record decisions and their rationale to manage the business and document how difficulties were addressed.
4. Insure the actual risks of your work
Professional indemnity or business liability insurance may cover certain damage to third parties. Directors’ and officers’ insurance, often called D&O, may cover certain management liability claims. These serve different purposes and include limits, deductibles and exclusions. Discuss your precise activities with the insurer; our Swiss business insurance guide helps prepare that conversation.
5. Document commitments between owners
Specify who can bind the business, who contributes funding and how departures will be handled. A shareholders’ agreement (in French) helps organise those relationships. Add a register of sureties, loans and pledged property: monitor these obligations throughout the business’s life.
Swiss legal structures explained on video
Sarah and Romain explain how the different structures work and compare. These French-language videos complement the liability distinctions in this guide.
Choose a structure that fits your commitments
Assess risk through three questions: what debts could the activity create, what obligations will you sign personally, and who will manage the company? An LLC or SA can protect private assets against ordinary company debts. That protection works best when contracts, guarantees and financial monitoring are consistent with your chosen structure.
Before launching, gather draft leases, financing agreements, major contracts and your funding requirements. This provides a practical basis for choosing, rather than relying only on the amount of capital.

Swiss business liability: frequently asked questions
Does a Swiss LLC limit every loss to CHF 20,000?
No. CHF 20,000 is the minimum share capital, not a cap on debts or losses. The company is liable with all its assets. Members may also lose loans or other investments and, depending on the circumstances, owe money under a personal guarantee or management liability.
Does an SA protect private assets more than an LLC?
Both separate company and private assets for ordinary company debts. Neither removes personal undertakings or management responsibilities. Also check unpaid SA share capital and any additional contribution obligations in an LLC’s articles.
Am I personally liable when I sign for my company?
Not merely by signing, if you validly represent the company and sign in that capacity. But check the contract: signing as a surety or co-debtor can create personal obligations. The parties’ identities and representation powers must be clear.
Is gross negligence required for directors’ liability?
Not always. Article 754 CO also covers negligence, subject to the other liability conditions: loss, breach of duty and causation. Gross negligence, alongside intentional violation, is the threshold under the specific Article 52 AHV/AVS regime.
Does leaving management or selling shares release a personal guarantee?
Not automatically. A guarantee may continue after a director’s departure or a share sale. Check its terms and obtain the creditor’s written confirmation of any agreed release. An agreement with the buyer may not release you towards that creditor.
Does D&O insurance cover every risk?
No. It may cover certain management liability claims according to the policy, which includes conditions, limits, deductibles and exclusions. It replaces neither directors’ duties nor a review of personal guarantees.
