The official Sheriff Sale filing packet decoded for investors. Understand what documents are required, key deadlines, filing rules, and what happens behind the scenes before every auction.
Every property that appears on the Allegheny County Sheriff Sale list had to go through a formal legal filing process months before auction day. Understanding what that process looks like — the documents, the deadlines, the rules — gives you a massive edge as a buyer.
When you see a status flag on AlleghenySheriffSales.com like "NSM" (No Service Made) or "Paperwork Deficiency," you'll now understand exactly what went wrong in the plaintiff's filing — and why that property is likely to be postponed.
The Big Picture
Before any property reaches the auction block, the plaintiff (the county, bank, or lien holder) must assemble a complete filing packet and submit it to the Allegheny County Sheriff's Office. If anything is missing, incorrect, or late — the sale gets postponed. That's why 30–50% of listed properties never actually sell on the scheduled date.
Here's every document the plaintiff must submit to schedule a property for sheriff sale, decoded into plain English:
This is the court order that authorizes the Sheriff to sell the property. The plaintiff gets this from the Allegheny County Sheriff's Office after the court enters judgment. No writ = no sale. As an investor, a case with writ issues is a red flag for postponement.
These are the hard rules from the Sheriff's Office — effective October 2023. Understanding them helps you predict which properties might get pulled from the list at the last minute.
11:00 AM Cutoff on Final Filing Day
No new real estate filings are accepted after Wednesday 11:00 AM on the last day to file. The Sheriff's Office is strict — no exceptions. Miss this deadline and you're waiting until the next month's sale cycle.
→ Investor note: When you see a property suddenly added to the list very late in the cycle, it either slipped in just before the cutoff or is a re-filed case from a prior postponement.
2:00 PM Daily Cutoff for All Filings
No real estate paperwork is accepted after 2:00 PM on any regular business day. This was implemented due to the high volume of filings and the need to enter everything into the computer system.
→ Investor note: This gives you a window — if you're watching the list the day before the sale, anything posted after 2 PM was from prior processing. Same-day last-minute filings are essentially impossible.
All Documents Must Be Typed & Original
No photocopies. No faxes. All documents must be legible, complete, typed originals. Signatures must be notarized in the state and county where the document was authored.
→ Investor note: Sloppy or incomplete paperwork gets rejected and the attorney must return the following day with corrections — causing delays that ripple through to the sale date.
$2,000 Deposit — Paid Immediately
The $2,000 Treasurer's Office deposit must be paid at the moment of filing. If you walk in without the check, your filing is rejected on the spot.
→ Investor note: This is why plaintiff attorneys come prepared. It also explains why properties are rarely filed and then immediately withdrawn — there's real money at stake.
No New Filings on Sale Day
No new real estate is accepted or processed on the day of the Sheriff Sale itself. The focus is entirely on running the auction.
→ Investor note: Sale day is locked. Whatever's on the list that morning is final for new additions. Postponements and stays can still happen, but no new properties are added.
Once a property is filed, the plaintiff (the county or bank's attorney) has ongoing responsibilities to serve (officially notify) the defendant and all lienholders. Failure here is the #1 cause of last-minute postponements.
Serve the defendant by Certified Mail
If the Sheriff's Office doesn't perform personal service on the defendant, the plaintiff's attorney must send the Notice of Sale by Certified Mail. They must file proof of this.
Serve all lienholders by Certificate of Mailing
Every other party with a recorded interest in the property must receive a Notice of Sheriff's Sale by Certificate of Mailing. Miss one — and the sale can be challenged.
File proof of service TWO Fridays before the sale
The plaintiff must file an original affidavit of service with the Allegheny County Department of Court Records AND a copy with the Sheriff's Office by the second Friday before the auction.
Upload documents to Attorney Portal within 48 hours
The ALL CAPS (short) and Long (legal) property descriptions must be uploaded to the ACSO Attorney Portal within 48 hours of the sheriff's package being accepted.
What "NSM" means on a listing
NSM = "No Service Made." The Sheriff's deputy attempted to personally serve the defendant at the property and no one was home — or the address was wrong. This triggers the plaintiff to serve by Certified Mail instead. If the mail is also returned undeliverable, the sale faces serious postponement risk. AlleghenySheriffSales.com flags these properties automatically.
