How Breaking a Lease Works in New Jersey
New Jersey is one of the most tenant-favorable states for early lease breaks. The duty to mitigate was established by the landmark New Jersey Supreme Court decision Sommer v. Kridel, 74 N.J. 446 (1977), which held that landlords must make reasonable efforts to re-rent a vacated unit rather than leaving it empty and holding the departing tenant liable for the full remaining rent.
What makes New Jersey exceptional is where the burden of proof falls. Under Sommer v. Kridel, the burden is on the landlord to prove they made reasonable mitigation efforts — not on the tenant to prove the landlord didn't. This is the reverse of most states, where the tenant typically bears the burden. If your landlord sues you for unpaid rent after a lease break, they must demonstrate they took reasonable steps to re-rent. If they can't, the court will reduce or deny the claim.
New Jersey also provides protection for domestic violence survivors under the Safe Housing Act (N.J.S.A. § 46:8-9.12). DV survivors may terminate their lease with 30 days' written notice. Notably, the landlord must return the security deposit within 15 business days (shorter than the standard 30-day return period) — a recognition that survivors often need funds quickly to secure safe housing.
Example: What You Actually Owe When Breaking a Lease in NJ
Your rent is $2,500/month and you break your lease with 6 months remaining. Your landlord lists the unit and re-rents it after 45 days at the same rent.
You owe approximately $3,750 for the 45-day vacancy — not $15,000. Under Sommer v. Kridel, the landlord bears the burden of proving they made reasonable efforts to mitigate. If the landlord can't demonstrate they listed the unit, showed it to prospective tenants, and didn't unreasonably reject applicants, the court will reduce or deny their claim. If the unit re-rents at a lower rate ($2,200/month), you may also owe the $300/month difference for the remaining lease term.
Frequently Asked Questions
What is duty to mitigate in New Jersey? ▼
Duty to mitigate means your landlord must make reasonable efforts to re-rent the unit after you break your lease. In New Jersey, this duty was established by the Supreme Court in Sommer v. Kridel, 74 N.J. 446 (1977). If the landlord re-rents, your liability is limited to the vacancy period and any rent shortfall. If the landlord makes no effort, a court will likely reduce or eliminate your liability entirely.
How much will I actually owe if I break my lease in New Jersey? ▼
You owe rent for the vacancy period until a new tenant is found. With 6 months remaining at $2,500/month and a 45-day re-rental, your liability is approximately $3,750 — not $15,000. If the new tenant pays less ($2,200/month), you may also owe the $300/month difference for the remaining months. The key NJ advantage is that the burden of proof falls on the landlord, not you.
What if my New Jersey landlord doesn't try to re-rent the unit? ▼
This is where New Jersey law is especially powerful for tenants. Under Sommer v. Kridel, the burden is on the landlord to prove they made reasonable efforts to re-rent. If the landlord sues you and cannot demonstrate they listed the unit, conducted showings, or considered qualified applicants, the court will reduce or deny the claim. You do not need to prove the landlord failed — they need to prove they tried.
Does breaking a lease hurt my credit in New Jersey? ▼
A broken lease does not appear on your credit report directly. However, if your landlord sends unpaid rent to a collection agency, that collection account will appear and can significantly damage your score. Future landlords also use tenant screening services that may flag a broken lease. Communicate with your landlord, document mitigation efforts, and negotiate a written agreement on your final liability whenever possible.
Why is the burden of proof on the landlord in New Jersey? ▼
This comes from Sommer v. Kridel, 74 N.J. 446 (1977), in which the New Jersey Supreme Court ruled that because the landlord has control over the property and the re-renting process, they are in the best position to prove what efforts were made. This tenant-favorable burden allocation means that if your landlord sues for remaining rent, they must affirmatively demonstrate they took reasonable steps to re-rent. If they cannot, the court will reduce or deny the claim — you don't need to prove a negative.
