Quick answer

An evidence loan contract usually refers to a written agreement or form documenting the temporary transfer of physical or digital evidence between authorized custodians. It can identify the item, record its condition, document each transfer, and set rules for storage, access, handling, testing, and return.

The word "loan" describes custody, not necessarily money or ownership. This type of document generally isn't a personal or financial loan agreement: it usually doesn't involve interest, repayment installments, or a borrower receiving title to the item.

A custody agreement also doesn't, by itself:

If police or another government agency took your property, find out how the item is classified before asking for it back. It may be held as:

That classification determines the request, deadline, and possible court process. The information below covers general U.S. procedures; state, local, and federal rules can differ.

Evidence loan contract versus property seizure

An evidence loan contract concerns custody: who has the item, what they may do with it, and how the transfer is recorded. A seizure concerns the government's authority to take or retain property.

For example, a police department might transfer a phone to a forensic laboratory under an internal evidence-transfer agreement. The agreement could list the phone's serial number, seal, condition, transfer date, and authorized testing. That record helps document who handled the phone and when.

The agreement doesn't determine whether the original seizure was lawful or whether the agency must return the phone. A complete custody record can support the item's handling history, but the applicable court decides questions about authentication and admissibility.

Identify what is holding your property

Evidence in a pending case

An agency may retain evidence while an investigation or court case is pending. Local policies often distinguish evidence from ordinary property. For example, the Metropolitan Police Department's Evidence Control page says evidence is generally held until pending court action ends.

Ask the agency whether the item is still needed for an investigation, trial, appeal, or another authorized purpose. Don't assume that an arrest, dismissal, or scheduled trial date means the property is immediately available.

A preservation order

A court may require an agency or another custodian to preserve property or records. The U.S. Department of Justice identifies a judicial preservation order as an exception to its federal process for disposing of certain seized evidence.

Read the order carefully. Check which property it covers, who must preserve it, and how long the requirement lasts. A return request should not be treated as permission to disregard the order.

Forfeiture

Forfeiture is different from an ordinary evidence hold. The FBI's asset forfeiture overview describes forfeiture as an in rem action against property rather than a person.

If you received a forfeiture notice, follow the instructions in that notice instead of relying only on a general evidence-return request. Federal forfeiture may be administrative or judicial, and the Justice Department's forfeiture guidance explains that different procedures can apply. State and local agencies use their own rules.

Treat the notice as a formal legal document, not as a routine property-room receipt. Missing the stated claim or court deadline can affect your options. A general email to the evidence unit may not preserve a forfeiture claim.

Safekeeping or another property hold

Some property is held for safekeeping or an administrative reason rather than as trial evidence. Check the receipt, inventory, or notice for the category assigned to the item.

If the category isn't clear, ask the agency in writing to identify it and tell you which office handles release. The ordinary return process may not apply if the item is alleged to be contraband, belongs to someone else, is subject to a court order, or has entered forfeiture proceedings.

Steps to request seized property back

1. Gather your records

Keep copies of:

Send copies rather than original documents unless the agency specifically requires an original. Keep a separate record of when each document was sent.

2. Find the current custodian

Start with the evidence unit, property room, or agency named on your receipt. If the item was transferred under an evidence loan contract, ask for the current custodian and the date of the transfer.

Request written answers to these questions:

  1. What is the property's current status?
  2. Where is it being held?
  3. Is it still needed as evidence?
  4. Has it been transferred to another agency, laboratory, or court?
  5. What event or approval permits its release?
  6. Does a preservation order or forfeiture case apply?
  7. What form, hearing, or court filing is required?
  8. Is there a deadline for making the request?

An agency may not disclose every investigative detail. Even so, a written request gives you a clearer record of the status and instructions than a phone conversation alone.

3. Send a focused return request

Identify the item precisely and ask for both its status and the procedure for seeking its return. Include proof that you own or are entitled to possess it, but avoid making unsupported claims about the investigation.

You can adapt this format:

Subject: Request for status and return procedure for seized property

I am requesting written confirmation of the status of [item and identifying number], taken on [date] in connection with case or incident number [number].

Please confirm the current custodian, whether the item remains necessary for an investigation or proceeding, whether any preservation or forfeiture process applies, and the steps and deadline for requesting its return.

I have attached copies of [receipt and proof of ownership]. Please send the response to [mailing address and email].

If a formal notice provides a claim form, mailing address, court, or response deadline, use that process as well. Don't assume that sending a general request extends or preserves the deadline in the notice.

4. Keep a communication and condition log

Save the receipt, request, attachments, delivery confirmation, replies, and names of people you contacted. Record the dates and the exact instructions you received.

When property is released, inspect it before signing a receipt. Note missing parts, damage, changed seals, or differences from the original inventory. Ask for a copy of the release document and any condition report.

5. Escalate through the proper channel

If the evidence office doesn't resolve the issue, ask for the agency supervisor or the office responsible for evidence control. Depending on the case, the next step may involve the prosecutor's office, court clerk, forfeiture unit, or a court filing.

For a federal criminal matter, Federal Rule of Criminal Procedure 41 provides a procedure under Rule 41(g). A person aggrieved by an unlawful search and seizure or by the deprivation of property may move for the property's return. The motion must be filed in the federal district where the property was seized.

Rule 41(g) doesn't automatically apply to state or local cases. Filing a motion can also have procedural consequences, so a local attorney or qualified legal-aid organization can help identify the correct state or federal procedure. This is general information, not legal advice.

What an evidence loan contract should cover

If an agency, laboratory, museum, or other custodian asks you to review or sign an evidence loan contract, check whether the document clearly addresses:

A private form shouldn't be assumed to control every agency or jurisdiction in the United States. It also shouldn't be described as a guarantee that a court will admit the item.

Digital devices and electronic records

Federal Rule 41 recognizes that a warrant may authorize the seizure of electronic storage media or the seizure or copying of electronically stored information. Depending on the warrant and case, an agency may retain the physical device, create a forensic copy, or use both approaches.

If your phone, computer, or storage device was seized:

A digital hash, timestamp, or blockchain entry may help document handling, but it doesn't automatically establish ownership or admissibility in every court. Those questions depend on the applicable law and the judge's rulings.

What happens after a case ends?

Case closure doesn't always mean automatic return, and it doesn't always mean immediate destruction. The item may still be covered by a separate order, forfeiture process, or agency disposition rule.

For certain closed federal criminal cases involving evidence seized and retained by a Department agency, the Justice Department's disposal procedure states that there is a presumption favoring disposal after required notice and other criteria are met. The procedure describes beginning the disposal process at the expiration of the thirtieth day after notice, while recognizing exceptions such as a court preservation order.

That is a federal Department policy, not a universal 30-day deadline for every state or local agency. Local procedures can set different transfer, notice, and disposal rules. Ask for the agency's written disposition policy and confirm whether your item is covered by a court order or forfeiture case.

If you learn that disposal is being considered, respond using the notice's stated method and deadline. Keep proof of delivery, and ask for confirmation that the agency has recorded any claimed hold or preservation request.

Common mistakes to avoid

Start by identifying the item's current custodian and legal status in writing. Then follow the specific return, forfeiture, preservation, or court procedure that applies to that status.
