Clients across Memphis, Bartlett, Germantown, Collierville, Millington, Jackson, and communities throughout Shelby, Fayette, Tipton, Madison, and the surrounding West Tennessee counties come to Granite for one reason: the truth, documented in a way that holds up — whether that’s in a family law proceeding, an insurance claim, a corporate personnel matter, or a private family decision that was never meant to become public.

Private investigator services in Memphis & West Tennessee.

Granite provides licensed, discreet investigative services to individuals, families, attorneys, and businesses throughout Shelby County and West Tennessee.

Surveillance

Discreet, well-documented surveillance for infidelity, insurance, and workers’ comp matters — timestamped video, GPS-corroborated logs, and reports built to hold up under cross-examination.

Infidelity Investigations

Confidential surveillance and evidence-gathering built around discretion first. Every case is handled by a single investigator you can reach directly, never a rotating team.

Criminal Defense Support

Witness re-interviews, alibi verification, and scene review conducted under attorney direction — giving defense counsel the same investigative rigor the state brings to a case.

Skip Tracing & Locates

Locating individuals for legal service, asset recovery, and family matters using lawful public and proprietary records — not guesswork.

Fraud Investigations

Insurance, workers’ comp, and corporate fraud investigations documented with the chain-of-custody standards claims and litigation require.

Child Custody & Family

Sensitive, court-ready documentation for custody disputes, parental fitness concerns, and family law matters — handled with discretion and care.

Corporate Investigations

Internal theft, employee misconduct, due diligence, and vendor integrity investigations for Memphis and West Tennessee businesses.

Asset Investigations

Locating and documenting assets for judgment recovery, divorce proceedings, and business disputes across financial and property records.

Background Checks

Pre-employment, tenant, and personal background investigations built on verified primary-source records, not aggregator databases.

What sets a Delator Group investigation apart.

Corporate Structure, Not a Freelancer

Every investigator works inside Delator Group’s corporate structure — not as an independent contractor you’ve never vetted. Your case sits inside a licensed company, not a one-person operation.

Single Point of Contact

You work with one senior investigator from intake to final report — never a rotating queue of unfamiliar names or a call center reading your case number back to you.

Zero Subcontracting

Granite never hands your case to a third-party investigator outside the firm. The person who takes your call is the person doing the work.

Licensed & Chain-of-Custody Disciplined

Every investigator holds active Tennessee PI licensure and follows Delator Group’s internal documentation and evidence-handling standards on every engagement.

Real surveillance. Real documentation. No shortcuts.

Every Granite investigation is grounded in hands-on fieldwork — discreet observation, verified locates, and organized case files — carried out by licensed investigators who show up in person, not a subcontracted name pulled from a national directory.

Memphis-based. West Tennessee, covered.

Headquartered in Shelby County, Granite Investigative Group serves clients throughout all twenty-one counties of the West Tennessee grand division.
