Investigative Consulting in South Dakota for Attorneys, Companies and Individuals

01Why consult first

Why a Consultation Should Come Before Field Work in South Dakota

Field work in South Dakota is expensive mostly because of distance. A single surveillance day in the Black Hills for a client in Sioux Falls can involve roughly 349 miles of I-90 each way, a time zone change and, in winter, the chance of a closure. Spending that money on the wrong question is the most common mistake we see. A few hours of consulting can confirm whether the fact you want is obtainable, whether it matters legally and whether a cheaper source exists. That discipline runs through how Delator works across South Dakota.

A consultation also protects you from evidence that cannot be used. People often arrive having already recorded calls, followed someone or downloaded messages from a shared account. Some of that may be fine and some may create exposure. We sort it out, explain the risks plainly and suggest what to stop doing. If field work is the right next step, you leave with a written plan and price, matched against our published South Dakota pricing, so there are no surprises.

02For attorneys

Litigation Consulting Matched to South Dakota's Court System

South Dakota's Unified Judicial System runs trial courts through seven judicial circuits that cover all 66 counties, with magistrate courts handling civil claims of $12,000 or less, small claims, misdemeanors and many protection orders. Federal cases go to the District of South Dakota in Sioux Falls, Rapid City, Pierre or Aberdeen. We help counsel decide which facts to develop, in what order and with what budget, given the forum and the discovery calendar. That planning feeds directly into our broader investigative support for South Dakota law firms.

Typical consulting work includes reviewing pleadings and discovery to find factual gaps, ranking witnesses by value and difficulty, identifying public records worth requesting and flagging evidence that may be challenged. Under SDCL 1-27-37, a public records officer generally has 10 business days to respond to a written request after an informal denial, which affects timing. We often recommend background research on key witnesses first and, before trial, juror background research within ethical limits, depending on counsel's needs.

03Criminal defense

Consulting on South Dakota Criminal Defense Investigations

Defense investigations succeed when they test the State's theory rather than simply retracing it. We review police reports, discovery and timelines, then recommend interviews, scene work and records requests that answer specific questions. Our criminal defense investigators then carry out whatever counsel approves. Pricing for defense work follows case-based minimums: misdemeanor defense from $750, a single felony from $1,000 and multiple charges from $1,500, which our felony defense investigation page explains in more detail.

Appointed counsel face a different budget reality. Each South Dakota county funds and runs trial-level indigent defense through a public defender office, contract attorneys or court-appointed private lawyers, and in 2024 the Legislature created the Office of Indigent Legal Services to handle felony and abuse-and-neglect appeals. Requests for investigator funding generally go through the court and county process, which varies, so we help appointed lawyers write a focused, defensible request. Our support for appointed counsel describes how that collaboration usually works.

04For individuals

Consulting for Individuals, Families and Self-Represented Parties

People without lawyers need clear guidance more than anyone. In custody matters, SDCL 25-4-45 directs courts to the child's best interests, and South Dakota courts may, but are not required to, consider the Fuerstenberg factors, including parental fitness, stability, primary caretaker and harmful parental misconduct. Not every unflattering fact counts, because misconduct generally matters only if it specifically harms the child. Our guide to custody investigations in South Dakota explains which lawful evidence tends to help.

We also consult on safety and relationship questions. Someone receiving repeated unwanted messages may be dealing with stalking under SDCL 22-19A-1, which covers harassment through electronic and digital communication, and protection order petitions under SDCL 22-19A-8 need a sworn affidavit of specific facts. We help organize those facts, explain what an investigator can add and point you to the right court. For harassment concerns, see our stalking investigations, and for relationship questions outside marriage, our non-married infidelity investigations.

05For employers

Consulting for South Dakota Employers and Business Owners

Employers usually call after a complaint, a loss or a rumor and before they know what to do. Under the South Dakota Human Relations Act, SDCL 20-13-10, discrimination based on race, color, creed, religion, sex, ancestry, disability or national origin is prohibited in employment, and charges generally must be filed within 180 days under SDCL 20-13-31. A fair internal investigation protects both the employee and the company. We help design one, and complaints of harassment move into our workplace harassment investigation service.

Other consulting work for businesses includes planning a response to suspected theft, preparing for a sensitive termination and screening finalists for senior positions. Employment in South Dakota is generally at will under SDCL 60-4-4, but statutes and contract terms can limit it, so counsel should review any decision built on investigative findings. We recommend the least intrusive step that answers the question. When a leadership hire is at stake, an executive candidate background check is often the most cost-effective first move.

06Second opinions

Reviewing Another Investigator's Work in a No-License State

South Dakota has never adopted a statewide private investigator license. A 1995 licensing bill, HB 1301, failed, and HB 1182 in 2013 was deferred 13 to 0 in committee. That means anyone can advertise as an investigator, and clients sometimes discover the problem only after paying for a report that cannot be used. We review existing work for method, documentation, legality and completeness, then tell you plainly what holds up. Our checklist for vetting South Dakota investigators covers the same points.

Common problems include surveillance video with no time stamps or vantage notes, gaps in the chain of custody, conclusions not supported by observations and evidence gathered by trespass or by recording conversations the investigator was not part of. Delator Group is a licensed Tennessee private investigation firm and holds its own work to that standard in every state where it operates. If repairs are possible, we explain how, and if new surveillance documentation is needed, we scope it.

07Evidence

Preparing Investigative Evidence for South Dakota Courtrooms

Evidence has to survive a challenge. Recordings must comply with SDCL 23A-35A-20, which generally requires the consent of a party to the conversation, and our explainer on recording someone legally in South Dakota explains how that plays out. Photographs and video need dates, times, locations and the investigator's vantage point. Witness statements should separate what a witness saw from what they heard. We review evidence with those standards in mind and recommend fixes before a hearing rather than after an objection.

Service records matter too. Under SDCL 15-6-4(g), proof of service must state the time, place and manner of service, and a defective return can undo weeks of work. Our South Dakota process serving team prepares affidavits to that standard. For appellate or state-agency matters centered in the capital, our investigators near Pierre can retrieve records in person. The Supreme Court sits at the State Capitol, and a proposed administrative merger of the Fourth and Seventh Circuits is under review.

How it works

How Investigative Consulting Works

1. 01

   Initial conversation

   You describe the situation and send what you have. We confirm there is no conflict of interest and agree on how many consulting hours the review is likely to need.

2. 02

   Review and analysis

   A senior investigator reviews your documents, identifies gaps and risks and checks what South Dakota law and local court practice mean for each possible next step.

3. 03

   Written recommendations

   You receive a short written plan that ranks options by value and cost, explains what each would produce and states what we would not recommend doing at all.

4. 04

   Your decision

   You decide what happens next. You can stop there, hire another firm, do some tasks yourself or approve a written scope and price for Delator to carry out.
