What counts as a default
The lease itself defines default, and commercial leases tend to define it broadly. Missing rent is the obvious example, but it is far from the only one. Typical events of default include:
- Unpaid base rent or additional rent, such as common area maintenance (CAM) charges, real estate tax pass-throughs and insurance contributions
- Using the premises for something outside the permitted-use clause
- Letting required insurance lapse or failing to deliver certificates
- Assigning the lease or subletting without the landlord's consent
- Failing to maintain or repair what the lease makes the tenant's responsibility
- Going dark or abandoning the space where the lease requires continuous operation
- Insolvency events, liens filed against the premises, or a guarantor's default
Some leases also contain cross-default language tying this lease to another lease or loan with the same landlord. Read the default article as a whole rather than only the rent clause.
Notice and cure: the step both sides get wrong
Most commercial leases require the landlord to give written notice of default and allow a cure period before it can exercise remedies. Monetary defaults often carry a short cure window; non-monetary defaults usually carry a longer one, sometimes extended if the tenant is diligently working on the fix.
Delivery details matter. The notice clause may require certified mail, overnight courier or delivery to a specific address or attorney. A landlord who sends notice the wrong way may have to start over. A tenant who changes its address without telling the landlord may find that a notice was effective even though nobody read it. Both sides should keep proof of what was sent, when and how.
The landlord's toolkit
Depending on the lease and New Jersey law, a landlord facing a default may be able to:
- Collect unpaid rent, additional charges and late fees the lease allows
- Apply the security deposit and require the tenant to restore it
- Terminate the lease or the tenant's right to possession
- Bring a court proceeding to recover possession
- Enforce a personal guarantee
- Re-let the premises and pursue the shortfall, subject to the lease and applicable rules on mitigation
What a landlord generally should not do is resort to self-help, such as changing the locks or removing the tenant's property, without following lawful procedures. New Jersey law restricts forcible entry, and a lockout can expose the landlord to claims. New Jersey courts have also generally expected landlords to make reasonable efforts to re-let space rather than simply let damages accumulate, though how that applies to a particular commercial lease depends on its terms and the facts.
A tenant's practical options
If your business has fallen behind or received a default notice, speed matters more than anything else. Options narrow every week you wait.
- Read the lease and the notice the same day. Identify the alleged default, the cure deadline and the remedies the landlord is threatening.
- Talk to the landlord early. Many landlords would rather keep a paying tenant than search for a new one. Payment plans, short-term rent deferrals or a reduced footprint are often on the table if you propose them before the relationship sours.
- Cure if you can, and get it in writing. Pay the arrears or fix the problem within the cure period, then ask for written confirmation that the default is resolved.
- Consider assignment or subletting. If the lease permits a transfer with consent, finding a qualified replacement tenant may solve the problem for everyone. The firm's page on assigning a commercial lease explains the consent process.
- Check the landlord's own obligations. Unmade repairs, failed services or co-tenancy problems may affect your position, though withholding rent without a clear lease right is risky.
- Document everything. Keep every notice, payment record, photograph and email.
Putting the resolution in writing
Most lease defaults end with a written agreement rather than a judgment. Common forms are a forbearance agreement (the landlord holds off while the tenant follows a payment schedule), a lease modification (new rent, term or space), and a surrender agreement (the tenant leaves early on agreed terms).
Whatever the form, the document should state the exact amount owed, the payment schedule and what happens if a payment is missed, the condition in which space must be returned, how the security deposit is handled, which claims are released by each side, and, critically, whether any personal guarantee is released, reduced or left in force. Our article on commercial lease personal guarantees explains why that last point deserves careful drafting.
Prevention
Lease terms to fix before anything goes wrong
The best time to handle a default is when the lease is negotiated. Before signing or renewing, aim for:
- Reasonable notice and cure periods for both monetary and non-monetary defaults
- A capped or burn-off personal guarantee
- Clear allocation of repairs, utilities, CAM and tax increases
- Assignment and subletting rights that let you exit by finding a replacement
- Notice addresses that will still be monitored years from now
The firm's commercial lease review and negotiation service focuses on exactly these terms. For a broader overview for tenants and landlords, see commercial lease services in New Jersey.
Questions & answers
Lease default questions
Can a commercial landlord in New Jersey change the locks for unpaid rent?
Generally, a landlord should not use self-help such as a lockout without following lawful procedures, and doing so can create liability. The landlord's proper route is usually notice under the lease followed by a court process to recover possession. Your specific lease and facts matter, so get advice before either side acts.
Does ending the lease early release my personal guarantee?
Not automatically. Whether a guarantee survives an early termination or surrender depends on its wording and on what the surrender agreement says. If you negotiate an exit, ask for an express written release of the guarantor, or at least a defined cap on what remains.
What if the landlord is also in breach?
Landlord failures, such as ignored roof leaks or loss of promised services, can strengthen a tenant's position in negotiations and may support claims. But many commercial leases make rent payable without set-off. Stopping rent payments without a clear lease right often weakens the tenant's case, so document the landlord's breach and raise it formally instead.
