There is no set number of days for how long police can hold your property for evidence. The rule courts apply is reasonableness: officers can keep your belongings as long as the items have genuine evidentiary value and the government is moving the case forward with reasonable diligence. In practice that means a few weeks if no charges are filed, months while a case is pending, and sometimes years when a prosecution runs through trial and appeals.
What “Reasonable” Actually Means
No federal statute and no universal state law imposes a hard deadline. Instead, judges look at the totality of the circumstances when someone challenges a hold. A handful of factors come up again and again:
- How much the seizure disrupts your life. Losing your only car hits harder than losing a box of old receipts, and the greater the interference with your use of the property, the harder the government has to work to justify the delay.
- How long the hold has run. A two-week hold for lab testing is easy to justify. A two-year hold with no charges filed is not.
- Whether you pushed back. Courts look at whether you asked for the property, checked on its status, or otherwise asserted your possessory interest. Sitting quietly for a year makes it easier for the government to argue the delay was harmless.
- Government diligence. Were investigators actively working the case, or did your property sit in an evidence room while nothing happened?
- Complexity. Multi-agency investigations, forensic analysis, and co-defendants all justify longer holds.
The longer police hold your belongings without a clear investigative reason, the more vulnerable the seizure becomes to challenge.
Typical Timelines
If the investigation fizzles and no charges are filed, your property should come back within weeks to a couple of months, though bureaucratic delays often stretch that. If charges are filed, expect the hold to last until the case reaches final disposition, including any appeals. Complex cases involving multiple defendants or organized crime can easily mean years. Courts give prosecutors wide latitude while a case is genuinely active.
The method of seizure matters if you want your property back faster. If the seizure itself was unlawful — no warrant and no recognized exception — that becomes your strongest argument for immediate return.
Phones, Computers, and Other Digital Devices
Digital devices sit in evidence rooms longer than most physical items. Forensic analysis of phones and computers routinely takes months, and in some jurisdictions over a year. Even routine forensic testing like toxicology averages more than 30 days, and digital analysis is typically far more involved.
There’s a wrinkle that catches most people off guard. Even after police return the physical device, they almost certainly kept a forensic copy of what was on it. Law enforcement agencies routinely image phones and hard drives at intake, and those digital copies stay on agency servers under their own retention schedules, often for years after the case ends. For serious felonies, some agencies keep forensic copies for a decade or more. Capital cases can push retention to 100 years.
If the data itself concerns you more than the hardware, ask the detective whether a forensic image was made and under what retention schedule it falls. Deleting that data usually requires a separate court order, and success is not guaranteed.
Property That Won’t Come Back
Two categories fall outside the ordinary return process. Contraband — items that are illegal to possess, like certain drugs or unregistered weapons — will be destroyed after the case concludes.
Property the government classifies as an “instrumentality” of a crime, like a vehicle used to transport drugs or a computer used to commit fraud, can be pulled into civil asset forfeiture. Forfeiture is a separate legal proceeding from the criminal case, with its own timeline. In a federal forfeiture action, the government must send you written notice within 60 days of the seizure. If state or local officers seized the property and turned it over to a federal agency, that deadline extends to 90 days.1Office of the Law Revision Counsel. 18 USC 983 – General Rules for Civil Forfeiture Proceedings
Once you receive a forfeiture notice, you have a limited window to respond. The exact deadline depends on whether the proceeding is judicial or administrative and which agency is involved. Missing the window can mean permanent loss of the property. Treat a forfeiture notice with the same urgency as a lawsuit.
Ask the Case Detective First
Start with an informal request. Contact the detective or officer assigned to the case and ask whether the property can be released. This works more often than people expect, especially when the case is closed or the specific item isn’t central to the prosecution. The detective has to authorize the release before the evidence division will hand anything over, so going straight to the property room without that authorization is a wasted trip.
Before you call, pull together:
- The property voucher or receipt police gave you at the time of seizure. It lists what was taken and includes a reference number the property room uses to track your belongings.
- The case or police report number.
- Proof of ownership: sales receipts, vehicle titles, serial number records, insurance documentation, or photographs of the items in your possession. Some jurisdictions accept a sworn affidavit of ownership signed under penalty of perjury.2Forfeiture.gov. Petition Information
- Valid government-issued photo ID matching the name on the property records.
If someone else needs to pick the property up for you, many departments require a notarized authorization letter. Call the property room ahead of time to confirm what they need.
Filing a Motion for Return of Property
When the informal route fails, the formal option is a Motion for Return of Property. Under Federal Rule of Criminal Procedure 41(g), any person “aggrieved by an unlawful search and seizure of property or by the deprivation of property” can file this motion in the federal district where the seizure occurred. If the court grants it, the judge orders the property returned, though the court may impose conditions to preserve access to the evidence for later proceedings.3LII / Legal Information Institute. Federal Rules of Criminal Procedure, Rule 41 – Search and Seizure
Every state has an equivalent procedure, usually modeled on Rule 41(g) or codified in the state’s own criminal procedure rules. The motion typically requires you to identify the property, establish that you’re the lawful owner, and argue that the government no longer has a legitimate need to hold it. The government then gets to explain why it still does, and the court decides.
A few practical points. Courts are more sympathetic when the case is closed, charges were dropped, or you were acquitted. Filing during an active prosecution is possible but harder to win, because judges defer to the prosecution’s judgment about what evidence it needs. If the seizure itself was illegal, that strengthens the motion considerably. You don’t need a lawyer to file a 41(g) motion, but when significant property value is at stake, hiring one is worth the cost.
Deadlines That Run Against You
Two clocks can cost you your property or your right to recover for it, and both start running without any court action.
The first is the disposal clock. After a case concludes and the evidence is no longer needed, most agencies hold the property for a waiting period, commonly 90 to 180 days depending on the jurisdiction, before disposing of it through auction or destruction. Agencies generally have to make some effort to notify you first, but that effort can mean a single letter to your last known address or a published notice in a local newspaper. If you moved after the seizure and didn’t update your contact information with the department, you may never see the notice. Check in periodically after your case ends rather than assuming someone will track you down.
Biological evidence follows different rules. Most states require automatic preservation of biological evidence in serious criminal cases. In federal cases, the government must preserve biological evidence as long as a defendant remains imprisoned, and can only destroy it after giving the defendant 180 days’ notice and an opportunity to object.1Office of the Law Revision Counsel. 18 USC 983 – General Rules for Civil Forfeiture Proceedings Several states mandate permanent retention in death penalty cases.
The second clock applies when property is returned damaged, or never returned at all. For federal agencies, the Federal Tort Claims Act allows an administrative claim for monetary damages, and the deadline is two years from the date of the loss or damage. You submit a written claim to the agency, including a specific dollar amount and supporting documentation like repair estimates or proof of value. State and local agencies have their own tort claims procedures, often with shorter deadlines. A separate federal option is a suit under 42 U.S.C. § 1983 for excessive or unnecessary destruction during a search, though qualified immunity shields officers unless their conduct violated “clearly established” constitutional rights a reasonable person would have known about, and courts generally treat incidental damage during a lawful search as protected.4FBI Law Enforcement Bulletin.

They are strict and usually non-negotiable.
