Adjusters - investigate claims by conducting interviews, reviewing records, and performing inspections. Independent adjusters are independent contractors working for various insurers, especially in response to large events such as hurricanes or floods. Independent adjusters throughout the south and southwest worked for months on the Gulf coast following Hurricane Katrina. Public adjusters work for claimants to evaluate a claim and negotiate a settlement with an insurer.

Arbitrators - along with mediation, arbitration is a form of alternate dispute resolution. As opposed to mediators, in which a resolution must be agreed upon by all parties, arbitrators act as judges and are presented with evidence in a hearing, then issue a ruling that is binding on the parties.

Conflict coaching - is a relatively new tool in alternative dispute resolution. This one-on-one process is used to coach individuals to address and change destructive behaviors and attitudes that might hinder mediation or litigation.

Copy services - provide commercial copying service, whether print or digital. Most have the capability of copying voluminous or oversized documents, duplicating CDs, photographs, DVDs, tapes, and other media, and producing special jobs such as enlargements and mounting.

Couriers - more than simple delivery, couriers can also handle hand-filing documents at courts. Many couriers who work in litigation are also notary publics and so are very useful in getting affidavits signed.

Court records/abstract retrieval – as opposed to record retrieval, which usually concerns obtaining medical or employment records and can be done remotely, these vendors physically go to courthouses and other public buildings to obtain copies of public documents, including lawsuit pleadings, criminal records, and the variety of records maintained by county clerks. They also obtain documents used in real estate transactions and compile an abstract of title, which records all the documents that describe the history of ownership of a piece of property.

Court reporters - transcribe verbatim statements, speeches, depositions, and court proceedings. In addition to the steno machine used by virtually all reporters, court reporters also use audio recorders and laptops to create transcripts. Most can also create digital transcripts in ascii or e-transcript formats.

Courtroom playback - as the use of multimedia has grown, so too has the need for specialists to assist in the use of audio/video equipment. Playback technicians typically are versed in setting up equipment and integrating it into a court's system, then operating DVD players, PowerPoint projectors, overhead projectors, and Elmo machines.

Document coding - from Bates numbering or labeling (named for the Bates Automatic Numbering Machine) to the digital organization of documents, coding covers various methods of organizing and identifying documents. Coding can range from simple page numbers to time/date labels and copyright protection to creating digital document libraries.

Document scanning - many copying and litigation-support firms scan massive quantities of documents digital formats, allowing them to be transferred onto CDs, DVDs, or online document systems. Particularly useful in instances with large numbers of documents, scanning can make thousands or millions of pages securely accessible via the Internet and can make those pages much easier to produce to opposing parties.

eDiscovery - these vendors deal with a relatively new branch of discovery dealing specifically with the production of electronic data such as e-mails, instant messages, documents, databases, and CAD/CAM files. This rapidly-growing area necessitated amendments to the Federal Rules of Civil Procedure in 2006, and competent eDiscovery vendors are well versed in those rules.

Graphics/presentations - multimedia presentations can make a dramatic impact, and the range of trial aids has grown significantly. What began with trial boards to display timelines, enlarged illustrations, and deposition testimony now encompasses PowerPoint presentations, exhibit databases, and animated recreations of incidents.

Interpreters/Translators - interpreters allow legal professionals to communicate with non-English-speaking persons, especially in depositions, statements, and trial testimony. Translators, on the other hand, convert documents from one language to another. Most language specialists perform both interpreting and translating.

Jury consultants - assist in juror research, voir dire preparation, and jury selection. They also conduct mock trials and evaluate juror body language and behavior during trial. Many have backgrounds in the law and behavioral science.

Mediators - like an arbitrator, a mediator is a neutral party. But as opposed to an arbitrator, who serves as a judge, a mediator assists in negotiations and attempts to direct parties to resolution. While there is no requirement for mediators to be attorneys, most are either practicing or retired attorneys and/or judges.

Polygraph examiners - operate a polygraph or lie detector machine, which measures and records physiological responses while the subject is asked questions.

Private investigators - the mainstay of investigation remains field work: talking to people, gathering information and evidence, and performing surveillance. Modern investigators also provide a wide range of services, including background checks of criminal records, driving records, and financial records, locating individuals and non-published telephone numbers, asset searches, computer forensics, debugging and surveillance countermeasures, and transporting witnesses to and from trial.

Process service - perform service of legal documents, such as subpoenas or citations, on individuals or business entities. Process servers are authorized by courts to perform service.

Real-time court reporters - used in closed captioning of live events through keyboard or stenography equipment to transcribe speech into written text. Known as CART, for either Communication Access Real-Time Translation or Computer Assisted Real-Time Transcription, this is an extremely specialized skill and most court reporters do not provide the service.

Record retrieval - specialists in obtaining records from businesses or governmental agencies. Especially used in obtaining medical records, good record-retrieval professionals are skilled in dealing with various authorizations and requirements, acting as intermediaries with records custodians, issuing record requests, overseeing the completion of any documentation such as deposition on written questions, and obtaining copies of the requested records.

Vehicle appraisers - perform examinations and evaluations of vehicles, usually those involved in accidents. The evaluation determines the costs of repairs and the value of the vehicle.

Video production/editing - in addition to videography services, these vendors provide post-production services, including creating day-in-the-life videos, editing designations of deposition testimony and synchronizing them with the transcript for side-by-side display at trial or mediation, and converting footage into various digital formats.

Videographers - primarily used to videotape depositions and statements, but also used to visually document an accident scene, property damage, and personal injuries, or chronicle an expert's site inspection.
