Find the right office for your rental address

Use the municipality where the property sits. The clerk, rental registry and rent board can hold different records. They do not replace a court filing for your deposit.

Edison housing records and fair-rental questions have different routes.

Edison lists a Health Department housing section and a Fair Rental Housing Board. Use the record descriptions to choose the office, then distinguish those municipal inquiries from a deposit filing at the county court in New Brunswick.

Which registration should I request?

For covered one- and two-unit dwellings, the landlord identity form is filed with the municipal clerk; the two-unit owner-occupied exception matters. Larger buildings use DCA registration. Local rental licensing may add another record. A registration is a lead: verify the correct defendant and a permitted service address before filing.

Preparing to file yourself?

Use this optional worksheet to calculate your disputed amount, find the matching NJ court forms, and save a timeline and checklist. You can start the free analysis above without filling it out.

How much of your deposit are you disputing?

Subtract refunds and deductions you accept to see your disputed balance.

Enter 0 if nothing was returned. Accepted deductions are optional.

What counts as a deduction I accept?

Only include charges you agree the landlord may keep. Leave this blank if you are unsure; you can review individual charges in the analysis.

Accepting deductions reduces the refund you dispute. It does not waive separate statutory remedies or confirm that the landlord provided a complete statement.

Your disputed amount will appear here after you enter your deposit and refund.

Forms, timeline & checklist

Find the court forms for your entered amount, add costs and a timeline, and download or print your worksheet. These steps are optional before the free analysis.

Additional damages and court costs (optional)

Additional damages are an extra amount, not a total multiplier that already includes the refund. Use the New Jersey remedy rules to avoid counting the deposit twice. Court fees are listed separately; check which amounts your court includes in its limit.

Enter the deposit and amount returned, using non-negative dollar amounts with at most two decimal places.

See a sample calculation

Example only: $1,200 paid, $300 returned, and $100 in deductions accepted leaves $800 disputed. With no additional damages requested, the claim is $800. Example $35 filing and $10 service costs are recorded separately. These are illustrative amounts, not a fee quote. Check the current New Jersey court fee schedule.

Build your timeline (optional)

Record what happened, when, and the exhibit that supports it. Leave events that have not happened blank.

Check the ordinary NJ return deadline

Estimate timing from your move-out date, then check the tenancy-end date and exceptions in the NJ rules. This check does not add damages or change your form selection.

Have you confirmed that the deposit protections described below apply to your rental?

New Jersey's deposit law does not automatically cover you if your landlord lives in the building and rents out no more than two units. You can still bring yourself under the law by giving your landlord 30 days written notice that you are invoking the Rent Security Deposit Act - after that, its protections, including the deposit cap and the double-damages return rule, apply to your tenancy (N.J.S.A. 46:8-26). If unsure, leave this unanswered; the disputed refund can still be analyzed without assuming these statutory remedies.

One state law, local offices

Middlesex County uses New Jersey’s Rent Security Deposit Act. Municipal rent-control rules address separate questions.

30 days
The ordinary return and itemization period after tenancy termination.
2x moneys due
Recovery when the court finds for the tenant under N.J.S.A. 46:8-21.1.
1.5 months
The deposit cap for tenancies covered by the Act.

Start with what remains due after refunds and lawful deductions. An expired deadline alone does not establish that the entire deposit must be doubled. Owner-occupied properties with no more than two rental units have a coverage exception, with a tenant notice route to invoke the Act; seasonal rentals and displacement can change the applicable rules.

03 / From the generated demand letter

I demand payment of $900.00, the amount improperly withheld from my deposit.

A landlord may still pursue an unpaid accepted charge in a separate claim or counterclaim, so net recovery can be lower. Money already paid or retained toward that charge must be credited. The $200 rent balance retained in this sample is already excluded from the demand.

File through the Middlesex County Special Civil office

First confirm venue and your requested amount. The same NJ Courts kits apply across counties.

  1. 1. Put your demand in writing. List the disputed charges, subtract refunds and deductions you accept, and explain any additional damages separately. Send the landlord your demand and keep proof of delivery. See a prepared example.
  2. 2. Complete the official complaint. Use your calculation to choose the kit below. Confirm the defendant’s legal name and service address, and follow the kit’s signing and copy instructions. Above $20,000, review the Civil Part procedure.
  3. 3. File and check delivery. Follow the kit through JEDS, or confirm mail and in-person intake at 56 Paterson Street, New Brunswick, NJ 08903. The court arranges initial mail service. Check its status and contact the office if service fails.
  4. 4. Prepare for the hearing. Gather the lease, payment records, deductions, photos, messages and proof of your demand. Match each disputed amount to its evidence, and follow your hearing notice for submission deadlines and attendance.
Filing fees, waivers and the court’s full instructions

Small Claims: $35, plus $5 for each additional defendant and $10 mail service per defendant. Special Civil: $50 for a claim up to $5,000 or $75 above $5,000; $5 per additional defendant and $10 mail service per defendant. Ask about a fee waiver if you cannot afford filing. Check the current kits for payment and service details.

Plan for the next step

What if the landlord claims I owe money?

A counterclaim, including charges you accept, can reduce your net recovery. Check response deadlines and costs.

Could filing affect me as a renter?

A deposit lawsuit differs from eviction, but records may be public. Still renting or facing threats? Ask local legal aid.

What happens after I win?

A judgment does not automatically collect the money. Follow the NJ collection steps if unpaid.
