When a Lease Guarantee Gets Called

Posted April 01, 2026 in Uncategorized

A commercial lease gets signed. The business entity is the tenant. But somewhere in the document stack, often attached as an exhibit, there is a personal guarantee. Founders sign it without much pushback. Developers sign it to close the deal. And then, when the business hits a rough patch or a project stalls, the landlord calls the guarantor. That is when the exposure becomes real.

Volpe Law LLC works with founders, operators, and developers across Colorado who are dealing with the downstream consequences of guarantee language that was negotiated quickly and documented loosely.

What a Lease Guarantee Actually Does

A personal guarantee makes an individual, not just the business entity, liable for the obligations under a commercial lease. In practice, that means:

• Unpaid rent through the end of the lease term
• Restoration costs, operating expense reconciliations, and CAM charges
• Attorney fees if the landlord prevails
• Holdover liability if the tenant stays past expiration

For a five-year lease on 3,000 square feet of commercial space, the exposure on a full guarantee can run into six figures quickly. For a developer leasing anchor space in a retail or mixed-use project, it can be substantially more.

Bad-Boy Guarantees and Fraud Carveouts

In commercial real estate lending and structured leases, “bad-boy” guarantees are a specific category worth understanding. These are guarantees that are non-recourse by default, meaning the individual is not personally liable for the debt unless a specific triggering act occurs. Common bad-boy triggers include:

• Fraud or intentional misrepresentation
• Misappropriation of rent, insurance proceeds, or security deposits
• Filing for bankruptcy without lender consent
• Transferring assets in violation of the loan agreement
• Environmental violations

The fraud carveout is particularly litigated. Lenders and landlords sometimes argue that a misrepresentation in a rent roll, operating statement, or lease application constitutes fraud, which collapses the non-recourse shield entirely.

Founders and developers should not assume that “non-recourse” means no personal exposure. If the transaction involved any representations about revenue, occupancy, or financial condition, the fraud carveout is a live risk.

Trigger Events: When the guarantee  Becomes Active

Not every guarantee is callable on day one of default. Many commercial guarantees have specific trigger conditions. Understanding those conditions and the notice requirements attached to them is where litigation posture begins to take shape. Common trigger events include:

• Tenant default beyond a cure period, often 30 days for monetary defaults
• Tenant insolvency or bankruptcy filing
• Assignment or sublease without landlord consent
• Failure to maintain required insurance
• Lease termination by the landlord following default

Notice timing matters. If the landlord fails to provide proper notice before calling the guarantee, or pursues remedies in the wrong sequence under the lease, those procedural defects can become meaningful bargaining chips for the guarantor. A Denver business dispute lawyer evaluating a guarantee call will examine whether the landlord followed the notice and cure provisions before triggering personal liability.

Negotiating Position During Default

Once a guarantee is triggered, the negotiation is not over. The guarantor’s position depends on several factors.

The Landlord’s Mitigation Obligations

Colorado recognizes a landlord’s duty to mitigate damages following a tenant default. A landlord cannot simply let a space sit vacant and continue accruing rent obligations against the guarantor indefinitely. If the landlord made no reasonable effort to relet the property, that failure limits what can be collected, and it is a defense worth documenting early.

The Scope of the Guarantee

Was it a full lease guarantee or a capped guarantee? Many sophisticated tenants negotiate a cap, typically 12 to 18 months of base rent, rather than exposure for the full remaining term. If the guarantee is ambiguous on this point, that ambiguity tends to get litigated.

The Landlord’s Conduct

Did the landlord contribute to the default? Were there material misrepresentations in the lease negotiation about build-out obligations, co-tenancy requirements, or exclusivity provisions? These can give rise to affirmative defenses and counterclaims that change the settlement calculus.

Bankruptcy Timing

If the tenant entity files for bankruptcy, the automatic stay does not protect the guarantor. But how the landlord responds to the bankruptcy estate can affect what remains collectible under the guarantee.

In professional service environments, particularly medical practices and dental groups where real estate is tied to licensure, patient continuity, and regulatory compliance, a guarantee dispute can escalate into an operational disruption in addition to a financial one. That context should inform how quickly and strategically the dispute gets handled.

When to Contest, When to Settle

Not every guarantee call warrants full litigation. The analysis should be driven by the exposure amount, the strength of available defenses, the landlord’s mitigation conduct, and the cost of a protracted fight.

A Denver business dispute lawyer can assess whether the landlord’s position holds up, identify where the gaps in their claim are, and establish a realistic settlement range before any demand is answered. If you are facing a guaranteed call or anticipate one, the time to evaluate your options is before the landlord files suit.
