Diligent Search and Inquiry Services for Defendants, Heirs, Witnesses, and Missing Persons | GreatProcessServers.com

When repeated service attempts fail, skip tracing produces outdated information, or a defendant, heir, witness, debtor, or other important subject cannot be located, our Great Process Servers are ready to help. We provide professional Diligent Search and Inquiry services designed to locate difficult-to-find individuals, identify new addresses and actionable leads, confirm current whereabouts whenever possible, and document meaningful search efforts when the subject remains not found. Law firms, attorneys, paralegals, process servers, and case professionals rely on our experience to help overcome failed service attempts, resolve questionable addresses, and move cases toward successful service of process, alternate service, service by publication, or the preparation of an Affidavit of Diligent Search and Inquiry.

Failed Service Attempts and Skip Tracing Should Not Bring Your Case to a Standstill

An unsuccessful service attempt, bad address, or inconclusive skip trace does not necessarily mean there are no additional opportunities to locate and serve the subject. Our Diligent Search and Inquiry services go beyond basic database searches by carefully reviewing known information, analyzing address histories, researching public and investigative records, identifying relatives and associates, examining available employment and property information, and developing additional leads that may reveal the subject’s current whereabouts. Our objective is simple: locate the subject whenever possible and provide the information necessary to help you move forward with confidence.

Experienced Great Process Servers Who Locate Defendants, Heirs, Witnesses, Debtors, and Missing Persons

Finding a difficult-to-locate person requires persistence, experience, and the ability to recognize meaningful connections within large amounts of available information. Our Great Process Servers assist with locating defendants who have moved or are avoiding service, missing heirs in probate matters, witnesses with unknown whereabouts, debtors who can no longer be found at their last known address, and other individuals whose location must be determined. Every assignment is individually reviewed and strategically handled according to the facts of the case, the information available, previous service attempts, known addresses, and the specific objectives of our client.

Diligent Search Services After Failed Process Serving Attempts and Unsuccessful Skip Tracing

When ordinary process serving efforts have been exhausted and skip tracing has failed to produce a reliable address, a more comprehensive Diligent Search and Inquiry may be the appropriate next step. We evaluate prior service attempts, questionable addresses, available identifying information, address histories, public records, investigative resources, and other relevant leads to determine whether additional locations or service opportunities may exist. Our services help law firms and case professionals make informed decisions before investing additional time and money in repeated service attempts or proceeding with alternate service remedies.

Locate and Confirm Current Addresses Before Attempting Service of Process Again

Sending a Process Server to another unconfirmed address can result in additional delays, unnecessary expenses, and lost time. Our Diligent Search and Inquiry services are designed to develop, analyze, and verify potential address information before another service attempt is authorized whenever possible. By identifying stronger leads and evaluating the available information, we help clients concentrate their resources on locations with a greater likelihood of producing meaningful results and successful service of process.

Professional Diligent Search Services for Alternate Service and Service by Publication Matters

Cases involving alternate service or service by publication often require organized, credible, and well-documented search efforts demonstrating the steps taken to locate the missing or unavailable subject. Our Diligent Search and Inquiry services provide law firms, attorneys, paralegals, and case professionals with a structured investigative process designed to identify potential leads, pursue available information, document search efforts, and clearly report the results obtained. When the subject cannot be found, the work performed can provide valuable support when determining whether additional service attempts are appropriate or whether the matter should proceed toward an available alternate service remedy.

Affidavit of Diligent Search and Inquiry When the Subject Cannot Be Located or Served

Not every defendant, heir, witness, debtor, or missing person can be successfully located. When reasonable and documented search efforts have been completed and the subject remains not found or cannot be served, we can prepare a professionally organized Affidavit of Diligent Search and Inquiry. The affidavit clearly outlines the investigative efforts performed, records and resources reviewed, addresses researched, leads developed, service-related information considered, and results obtained. Our objective is to provide clear, credible, and well-organized documentation that helps demonstrate the diligence performed and supports your attorney, law firm, or case professional in determining and pursuing the appropriate next step.
