The Five Eviction Mistakes New Jersey Landlords Make — and How Each One Costs Them.

New Jersey's Anti-Eviction Act is one of the most tenant-protective statutes in the country. It limits the grounds on which a landlord can evict a tenant, requires specific procedural steps, and creates significant liability for landlords who get it wrong.

I have represented landlords in hundreds of eviction matters — and I have represented tenants challenging evictions that were improperly filed. The same mistakes come up again and again. Here are the five I see most often, and what each one costs.

Mistake #1: Self-Help Eviction

The most expensive mistake a landlord can make is attempting a self-help eviction — changing the locks, removing the tenant's belongings, shutting off utilities, or otherwise trying to force a tenant out without going through the court process.

Self-help eviction is illegal in New Jersey. Full stop. A landlord who engages in self-help eviction can face civil liability for damages, attorneys' fees, and — in some cases — punitive damages. I have seen landlords pay tens of thousands of dollars in damages for changing a lock.

Mistake #2: Improper Notice

Before filing an eviction complaint, a landlord must provide the tenant with proper written notice. The type of notice required — and the timing — depends on the ground for eviction.

• Non-payment of rent: a written demand for rent before filing
• Lease violations: a notice to cease and a notice to quit (in most cases)
• Disorderly conduct: a notice to cease
• Holdover tenancy: a notice to quit with the appropriate notice period

Landlords who skip the notice requirement, use the wrong form of notice, or serve notice incorrectly will have their eviction complaint dismissed — and will have to start the process over. That can add weeks or months to the timeline.

Mistake #3: Filing on Improper Grounds

New Jersey's Anti-Eviction Act limits the grounds on which a landlord can evict a tenant. You cannot evict a tenant simply because you want them out, because the lease has expired, or because you want to renovate the unit. You must have one of the statutory grounds.

Landlords who file eviction complaints on improper grounds — or who cannot prove the stated ground — will lose in court. Worse, if the eviction was retaliatory (filed because the tenant complained about conditions or exercised a legal right), the landlord can face significant liability.

Mistake #4: Accepting Rent After Filing

This is the mistake that surprises landlords most. Once an eviction complaint has been filed for non-payment of rent, accepting any rent payment from the tenant — even a partial payment — can waive the right to proceed with the eviction.

Do not accept rent after filing an eviction complaint without consulting an attorney. The rules on this are technical and the consequences of getting it wrong are significant.

Mistake #5: Appearing in Court Without Preparation

Landlord-Tenant Court moves quickly. Judges expect landlords to have their documentation in order — the lease, the notice, the rent ledger, the complaint. Landlords who appear without proper documentation, who cannot prove the amount owed, or who are unfamiliar with the procedural requirements often lose cases they should win.

I have seen landlords with legitimate claims lose in Landlord-Tenant Court because they were unprepared. I have also seen tenants with weak defenses succeed because the landlord made procedural errors. Preparation is not optional — it is the difference between winning and losing.
