Not every personal guaranty puts the full lease or loan balance on the guarantor for the entire term. Two of the most common limited forms — the rolling guaranty and the burn-off guaranty— cap exposure in different ways, and the difference between them changes what a guarantor actually stands to lose in year one versus year five.
This is an observational explainer: what each structure is, how they differ, and the terms that determine how much protection each one actually provides. It is general information, not advice about your guaranty. The legal judgment about what to do with that information is yours.
A rolling guaranty caps the guarantor's exposure at a moving window of obligations rather than the full remaining balance of the lease or loan. The most common form in commercial leases caps exposure at a set number of months of rent — often described as "the next twelve months" or "a rolling twelve months" — measured from the date of default. As the lease runs on without a default, the window rolls forward with it: the guarantor is never exposed to more than that fixed slice of the term, no matter how many years remain.
So when a guaranty says exposure is limited to a "rolling 12 months," it generally means: if the tenant defaults, the guarantor is responsible for up to twelve months of rent and related charges from that point — not the entire balance of a ten-year lease. What counts inside the window (base rent only, or also pass-throughs, fees, and costs of collection) is defined by the document, and that definition is where otherwise similar rolling guaranties diverge.
A burn-off guaranty (sometimes called a burn-down or reducing guaranty) starts at a higher exposure and steps down over time as the tenant or borrower builds payment history. A common pattern: the guaranty covers the full obligation in the early years, then reduces by a stated amount or percentage at each anniversary, and eventually extinguishes entirely — it "burns off."
The burn-off is almost always conditional. Negotiated versions of this provision commonly tie each step-down to conditions such as no uncured defaults, on-time payment through the period, or the business hitting a stated financial test. A default part-way through often freezes the burn-off at its current level — or, under some drafts, springs the guaranty back to its full original amount. That spring-back distinction is one of the highest-leverage details in the document.
Both forms appear most often in commercial leases, where a landlord-form guaranty starts as an unlimited, full-term obligation and negotiated versions commonly compress it into a rolling or burn-off structure. They also appear in loan guaranties and franchise agreements. They sit alongside other limited forms — the good-guy guaranty, dollar caps, and letter-of-credit substitutes — covered in our guaranty alternatives breakdown.
The label — rolling, burn-off, limited — describes the shape, but the definitions clause and the default section set the actual number. Contracts at this exposure level are commonly reviewed by counsel, and the questions above are the ones that determine whether a "limited" guaranty is genuinely limited. What you do with that information is your call.
