Diligent Search and Inquiry Services for Witnesses Not Served with a Subpoena | ServiceSubpoena.com

When a subpoena cannot be served because the witness moved, provided an incorrect address, cannot be found at known locations, or their current whereabouts are unknown, repeated service attempts may only create additional delays and expenses. Our professional Diligent Search and Inquiry services are specifically designed to locate witnesses who have not been served, develop new address information, identify potential locations, confirm current whereabouts whenever possible, and help create new opportunities for successful subpoena service. Attorneys, law firms, paralegals, litigation support professionals, and Process Servers rely on our experience when ordinary service attempts and basic skip tracing efforts have failed to locate an important witness.

When a Witness Cannot Be Located or Served with a Subpoena, We Take the Search Further

A failed subpoena service attempt, incorrect address, outdated forwarding information, or inconclusive skip trace does not necessarily mean the witness cannot be found. Our Diligent Search and Inquiry services go beyond ordinary database searches by carefully analyzing known information, prior service attempts, address histories, public records, investigative resources, property information, employment indicators, relatives, associates, and other available connections that may reveal the witness’s current location. Our objective is to develop reliable information, identify stronger service locations, and help your attorney, law firm, or litigation professional move forward with another informed attempt to serve the subpoena.

Locate Witnesses Who Have Not Been Served with a Subpoena

Finding a witness whose current whereabouts are unknown requires experience, persistence, investigative resources, and the ability to recognize meaningful connections within large amounts of available information. We assist with locating witnesses who have moved without leaving forwarding information, cannot be found at their last known address, are no longer associated with a known employer, have provided inaccurate contact information, or may be intentionally avoiding service of a subpoena. Every assignment is individually reviewed and strategically handled according to the information available, previous service attempts, known addresses, identifying information, case circumstances, and the specific objectives of the client.

Diligent Search and Inquiry After Failed Subpoena Service Attempts

When a Process Server has made repeated attempts to serve a subpoena and the witness cannot be found, continuing to return to the same address or sending another Process Server to an unverified location may accomplish little more than increasing costs and delaying the case. Our Diligent Search and Inquiry services examine previous service attempts, Process Server notes, questionable addresses, address histories, available identifying information, public records, investigative databases, relatives, associates, employment indicators, property records, and other relevant leads to determine whether additional locations and opportunities for subpoena service may exist.

Unsuccessful Skip Trace? A More Comprehensive Witness Search May Be Necessary

Basic skip tracing services and automated database reports frequently return outdated addresses, historical information, possible locations, and unverified data that may not establish where a witness currently resides or can actually be found. When a skip trace fails to produce a reliable address for subpoena service, our Diligent Search and Inquiry services provide a more comprehensive investigative approach. We analyze available information, compare multiple records and investigative resources, develop additional leads, and work to identify and confirm the strongest available locations before another subpoena service attempt is authorized whenever possible.

Locate and Confirm a Witness Before Attempting Subpoena Service Again

Sending a Process Server to another unconfirmed address can result in additional failed attempts, unnecessary expenses, missed deadlines, and valuable time lost. Our Diligent Search and Inquiry services are designed to identify, analyze, and verify potential address information before another subpoena service attempt is made whenever possible. By developing stronger leads, evaluating current information, and identifying locations with a greater likelihood of success, we help attorneys, law firms, and litigation professionals make better-informed decisions about where and when to attempt service of the subpoena again.

Finding Witnesses Who May Be Avoiding Service of a Subpoena

Some witnesses are difficult to serve because they have relocated, maintain multiple residences, frequently change addresses, stay with relatives or associates, work irregular schedules, or deliberately avoid contact with Process Servers. These assignments often require more than repeatedly visiting known addresses. Our Diligent Search and Inquiry services focus on identifying current connections, developing new leads, evaluating address activity, researching available employment and property information, examining relatives and associates, and identifying potential locations where the witness may currently reside, work, receive mail, or otherwise be lawfully located for subpoena service.

Develop New Addresses and Actionable Leads for Subpoena Service

The purpose of a Diligent Search and Inquiry is not simply to produce another list of possible addresses. Our objective is to develop meaningful information that can help create a realistic opportunity for successful subpoena service. We research available records, analyze address histories, examine connections between people and locations, identify potential employers and business affiliations, evaluate property and occupancy information when available, and pursue relevant leads that may help determine where the witness can currently be found. The results can help your Process Server concentrate service efforts on locations supported by stronger and more current information.

Diligent Search Services for Time-Sensitive Subpoena Assignments

Subpoena service frequently involves deposition dates, hearings, trials, document production deadlines, and other time-sensitive legal proceedings. When an important witness cannot be found, delays in developing a reliable service location can jeopardize valuable preparation time and create additional complications. Our Diligent Search and Inquiry services are handled with an understanding of litigation deadlines and the importance of promptly developing useful information. We work to provide responsive communication, meaningful investigative results, and actionable information that can help move the subpoena service assignment forward.

Documented Diligent Search Efforts When the Witness Cannot Be Found

Not every witness can be successfully located or served. When comprehensive and documented search efforts have been completed and the witness remains not found, we can provide a professionally organized report detailing the investigative efforts performed, records and resources reviewed, addresses researched, leads developed, information analyzed, and results obtained. This documentation provides attorneys, law firms, and litigation professionals with a clear record of the additional efforts undertaken to locate the witness after ordinary subpoena service attempts were unsuccessful.

Affidavit of Diligent Search and Inquiry for a Witness Who Remains Not Found

When appropriate to the circumstances of the assignment, a professionally prepared Affidavit of Diligent Search and Inquiry can document the extensive efforts undertaken to locate a witness whose whereabouts remain unknown. The affidavit can identify records and investigative resources reviewed, addresses researched, prior service information considered, relatives and associates identified, leads developed, available information analyzed, and the results of the investigation. Our objective is to provide clear, credible, and well-organized documentation of the search efforts performed so the attorney, law firm, or litigation professional can evaluate the appropriate next step in the legal proceeding.
