Commercial Lease Personal Guarantees: What Louisiana Business Owners Are Actually Signing
By Sebastian Uzcategui · Last reviewed: October 2026
The LLC signs the lease. You sign the page after it. That second signature puts your house, savings, and personal accounts behind every dollar the business owes the landlord, and Louisiana law gives you fewer escape routes than most owners assume.
A Guarantee Is a Suretyship
Louisiana does not have a separate body of “guaranty” law. A personal guarantee is a suretyship under Title XVI of the Civil Code, and courts treat the two terms as equivalent.
- Definition (C.C. art. 3035). Suretyship is an accessory contract in which you bind yourself to the landlord to perform the tenant’s obligation if the tenant fails to.
- Form (C.C. art. 3038). It must be express and in writing. A guarantee can’t be implied from conduct or a handshake.
- No acceptance needed (C.C. art. 3039). It takes effect once the landlord receives the signed writing. The landlord’s acceptance is presumed.
- Future obligations covered (C.C. art. 3036). The guaranteed obligation can already exist or can arise in the future, which is how one signature reaches rent that won’t come due for years.
- No head start for the tenant (C.C. art. 3045). You are liable for full performance without benefit of division or discussion. The landlord does not have to sue the LLC first, and with several guarantors it can pursue any one of them for the whole amount.
Why “Commercial Suretyship” Matters to Owners
The Civil Code recognizes three kinds of suretyship (art. 3041), and the classification changes how a court reads your guarantee.
C.C. art. 3042 makes a suretyship commercial if any one of four conditions applies, including when the principal obligor is a business entity or the obligation arises from the obligor’s commercial transaction. An owner guaranteeing an LLC’s commercial lease almost always fits.
That classification costs you two protections:
- No strict construction. Only an ordinary suretyship must be strictly construed in favor of the surety (C.C. art. 3044). A commercial guarantee is read like any other contract.
- No automatic release on lease changes. Under C.C. art. 3062, a material modification of the principal obligation without the surety’s consent extinguishes an ordinary suretyship. A commercial suretyship is extinguished only to the extent the surety is prejudiced, and the creditor has the burden of proving there was no prejudice or that it was smaller than the full obligation. Most lease guarantees also include advance consent to amendments, which removes even that argument.
Drafting rule: Read the guarantee as if a court will enforce every word as written, because for a commercial surety it will.
What the Courts Do With the Words
In Everest Stone LLC v. Louisiana Southern Stone, 54,437 (La. App. 2 Cir. 4/13/22), a surety argued he had guaranteed only cash-on-delivery purchases. The signature line he signed read that he personally guaranteed “all indebtedness.” The Second Circuit held that suretyship contracts follow the general rules of contract interpretation, read “all indebtedness” by its plain meaning, and affirmed judgment against him.
The court also noted in a footnote that if he had been a commercial surety, a material modification would extinguish his obligation only to the extent he was prejudiced. That is the same art. 3062 line that applies to most owners guaranteeing a business lease.
The takeaway for a lease guarantee: broad phrases such as “all obligations under the Lease,” “any renewal or extension,” and “solidarily with Tenant” will be applied as written.
Guarantee Terms: Landlord Form vs. Negotiated
| Term | Typical Landlord Form | Negotiated Alternative |
|---|---|---|
| Scope | All tenant obligations, including CAM, taxes, repairs, attorney fees | Base rent only, or a fixed dollar cap |
| Duration | Full term plus all renewals and extensions | Burn-off after a set number of on-time years |
| Amendments | Guarantor consents in advance to any lease change | Consent required for rent increases or term extensions |
| Exit on sale | Guarantee survives an assignment of the lease | Release when a creditworthy assignee or new guarantor steps in |
| Surrender | No release if the tenant vacates early | Liability limited to rent through a surrender date plus a set notice period |
| Multiple guarantors | Each liable for the full amount | Several (proportional) liability, stated expressly |
C.C. art. 3040 allows suretyship to be qualified, conditioned, or limited in any lawful manner. Every alternative in the right-hand column is enforceable if it is written into the guarantee.
A Five-Point Playbook Before You Sign
- Cap the dollars. Tie the guarantee to base rent, or to a fixed number of months of rent, rather than “all obligations.” Uncapped exposure includes build-out reimbursement, taxes, insurance, and the landlord’s attorney fees.
- Put an end date on it. Negotiate a burn-off: after a stated period of timely payments, the guarantee ends or steps down. Without one, it runs through every renewal.
- Strike blanket consent to amendments. Advance consent to “any modification” waives the protection art. 3062 would otherwise give you. Limit consent to administrative changes, and require your signature for rent increases, expansions, and extensions.
- Plan the exit before you need it. C.C. art. 3061 lets a surety terminate by notice to the creditor. But termination doesn’t affect obligations already incurred or obligations the creditor is bound to let the principal obligor incur when the notice arrives. For a lease, the landlord’s obligation to give the tenant the full term points to rent for the rest of that term. Negotiate a release tied to an assignment or a sale of your interest instead.
- Remember the privilege runs alongside you. Under C.C. art. 2707, the landlord also has a privilege on the tenant’s movables located on the premises. Equipment and inventory may be seized for the same debt you guaranteed, so a default can hit the business and you at the same time.
These points apply whether the LLC was formed last month or ten years ago. The entity shield under La. R.S. 12:1320 doesn’t reach obligations a member has personally guaranteed.

Frequently Asked Questions
Does my LLC protect me from a lease I personally guaranteed?
No. The guarantee is your own contract with the landlord. Limited liability protects members from the company’s debts, not from obligations they personally signed.
Can the landlord come after me before suing the business?
Yes. Article 3045 abolishes the benefit of discussion, so the landlord does not have to pursue the tenant first.
If the landlord and my company amend the lease, am I released?
Usually not. Owners guaranteeing a business lease are typically commercial sureties, released only to the extent the change prejudiced them, and most guarantees contain advance consent to amendments.
Can I cancel my guarantee if I sell my interest in the business?
You can send notice of termination, but it generally won’t cut off obligations the landlord was already bound to allow, which for a lease can mean the remaining term. A negotiated release is the reliable route.
Is a verbal promise to guarantee rent enforceable?
No. Suretyship must be express and in writing.
