Mendham borough records its held sale inside its redemption resolutions. Resolution 089-2026 and Resolution 068-2026 each recite that a tax sale certificate was sold to the same lien fund on December 15, 2025, on two lots on Galway Drive, and an older resolution recites a sale held on November 21, 2019 for delinquent 2018 sewer charges. A November 2025 resolution authorises the Tax Collector to hold an online lien sale through the state approved contractor; that authorisation date is not a sale date, and the December date here rests on the redemption recitals alone. Mendham borough is tied at 4,981 with Demarest borough; the tie stands as a tie. Plain Mendham in this set is Mendham Township, a separate municipality. Its 2020 census population is 4,981 (Census QuickFacts).
Selling office: Borough of Mendham Tax Collector, Mendham
Next sale: Monday, December 15, 2025 (most recent dated sale published). Two borough redemption resolutions give that December day in held words for certificates sold at the sale.
Read the Mendham borough redemption resolutions for this borough, and ask the tax office for the next sale day, because the borough papers its held sale in its resolutions and no sale notice of its own.
| The dated sale | Monday, December 15, 2025, recited in two borough resolutions of 2026: Resolution 089-2026 states that Tax Sale Certificate 25-00004 was sold to the lien fund named in the resolution on that day, on Block 1201, Lot 5, 26 Galway Drive, with a refund of $20,251.08 including a $15,200.00 premium, and Resolution 068-2026 states that Certificate 25-00003 was sold on the same day on Block 1201, Lot 3, 30 Galway Drive, with a refund of $3,334.07. The certificate numbers are identifiers, not dates. The date rests on these recitals; it is not a sale notice and not an audit sale line, and its sourcing is stated no more strongly than that. |
| Supporting sale | Thursday, November 21, 2019, recited in Resolution 098-2020, which states that the property at 1 Hampshire Drive was subject to tax sale on that day for delinquent 2018 sewer charges, under Certificate 2019-002. The two money figures for that redemption in the resolution's rendering do not agree with each other, and neither is printed here. |
| The authorisation | Resolution 161-2025 of November 5, 2025 authorises the Tax Collector to hold an online tax lien sale for 2024 amounts due, using the state approved contractor named in the resolution. November 5, 2025 is the meeting and authorisation date, not a sale date. Resolution 008-2025 authorises a tax lien sale in calendar year 2025 under N.J.S.A. 54:5-19, and the borough guidance states that all properties with a tax or sewer delinquency from the prior year are required by state statute to be placed on the tax sale list. |
| The collector's name | Not carried. A borough resolutions packet of January 2025 names a Tax Collector, but a borough resolution of May 2026 describes the current holder only as a temporary employee, unnamed, training a newly hired Deputy Tax Collector. With the current holder unnamed in borough sources, no name is printed on this page. |
| Next sale | Not published as a specific date beyond the December 2025 sale above. |
| Sale track | Not published as a label. The borough authorisation describes its online lien sale for prior year amounts due. |
| Registration | Not published in the sources read beyond the authorisation above. |
| Deposit | Not published in the sources read. |
| Bidding and payment | Not published beyond the authorisation terms above in the sources read. The state frame governs a borough sale itself, with the rate bid down from 18 percent and premium bidding below 1 percent, as set out below. |
| Redemption | Through the Tax Collector until a Superior Court judgment bars the right. The money side, interest at the bid rate, subsequent payments and the tiered penalty, is set out in the terms table below, on the state frame. |
| Struck off certificates | Nothing published in the sources read. Under the state frame a lien with no purchaser is struck off to the municipality at 18 percent and may later be assigned under 54:5-113 or sold at public sale under 54:5-114.1 and 54:5-114.2. |
| Format | Online through the state approved contractor, per the borough authorisation of November 2025. |

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Mendham borough, searchable by address, owner, or county, including parcels that never reach a sale list.

Mendham borough preparation starts with the redemption resolutions and the online authorisation. Two certificates on one street, sold on one December day to one fund, show how this borough's sale runs; the platform registration the authorisation names is the step to settle before the next sale opens.
| Deposit, Mendham borough | Not published. No borough sale notice carrying a deposit figure was found among the borough sources behind this page. |
| Payment, Mendham borough | Not published in the sources read beyond the authorisation terms above. The borough tax office governs payment for a Mendham borough sale. |
| What is sold | A tax sale certificate: a lien on the property for the taxes and municipal charges sold, recorded against the property. The property itself is not sold, the owner is not evicted, and the certificate holder's road to the property runs through redemption failing and a Superior Court foreclosure. |
| The interest ceiling | 18 percent per year, the maximum in 54:5-32. Bidding opens at 18 percent and the rate is bid down. The rate the winner takes is the rate the owner pays on redemption, and on contested liens in the publishing towns the rate is routinely bid to zero, which is where the premium takes over. |
| The premium | When a bidder offers less than 1 percent or no interest, the lien is struck off to whoever pays the amount due plus the highest premium. The premium is paid to the municipality and held by it: it earns the buyer no interest, it is returned if the owner redeems, and it escheats to the municipality if the certificate is neither redeemed nor foreclosed within five years. Model every premium dollar at zero percent, because that is what it earns. |
| Redemption money | The sum paid at the sale with interest from the sale date at the rate bid; after the certificate issues, plus the holder's expenses and subsequent municipal liens paid under 54:5-59 and 54:5-60; plus the tiered penalty in 54:5-61, 2 percent where the certificate exceeds 200 dollars, 4 percent above 5,000 dollars and 6 percent above 10,000 dollars. A municipality may separately fix a year end penalty up to 6 percent on delinquencies over 10,000 dollars under 54:4-67. |
| How long redemption really lasts | Until a Superior Court judgment bars it. There is no self expiring redemption date: the operative clocks are the foreclosure filing clocks, two years from the sale for a private holder, six months for a municipality or its assignee, plus the life of the court case. An owner facing a private holder has at least two years; an owner facing a municipal assignee may have far less. |
| The deed path | Foreclosure of the right of redemption in Superior Court, Chancery Division, or a municipal in rem action under 54:5-104.32 where its conditions are met. Since P.L.2024, c.39 (July 10, 2024) the process protects the owner's remaining equity, so the pre-2024 outcome, foreclosure simply transferring all equity to the holder, is not current law and no 2026 page should describe it as such. |
For Mendham borough the borough sources behind this page publish nothing about struck off certificates or assignment sales beyond the resolutions above. Under the state frame a borough lien with no purchaser is struck off to the borough at 18 percent and may later be sold by private assignment under 54:5-113, for not less than the liens by governing body resolution, or at public sale under 54:5-114.1 and 54:5-114.2, the second permitting sales below the amount due. The assignee of a municipal certificate inherits the municipality's six month foreclosure clock under 54:5-86, measured from the original sale date.
