Criminal Background Checks

LA Undercover private investigators logo

We are just as eager as you in getting the peace of mind you so desire...

Our licensed private investigators have a wide variety of skills and diverse backgrounds. With 25+ years of experience, we have an excellent track record of providing high quality investigation services. From start to finish, our knowledgeable, discreet, and detail oriented staff goes above and beyond to manage your expectations, remain 100% confidential and update you daily as events unfold on your case. 

We rely on the best investigative technology and techniques, and comply with the industry’s leading standards for surveillance, locating, record search, and process services. 

Need to know whether someone has a criminal past? Online “instant” record sites miss a great deal. Many county court records aren’t in those databases at all, names get mixed up, and results are often outdated or attached to the wrong person. LA Undercover’s licensed investigators conduct thorough criminal background checks the right way: by confirming identity first and then searching the courts and records where criminal history actually lives.

When Clients Hire Us

  • Before getting serious with someone you met online or through friends
  • Before marriage, moving in together or introducing a partner to your children
  • When a co-parent’s new partner will be around your kids
  • Before going into business with someone or letting them handle your money
  • When an attorney needs a verified criminal history on a party or witness
  • When someone in your life has given you reason to worry about your safety

What We Search

  • Identity verification first: confirming full name, date of birth, aliases and address history so records are matched to the right person
  • County criminal courts where the person has lived, worked and spent time, not just a national database
  • Federal court records for federal criminal cases
  • Other states where the person has lived, through our nationwide network
  • Sex offender registries
  • Restraining orders and protective orders where available
  • Civil litigation, judgments and bankruptcies that round out the picture

Why Not Just Use a Website?

People-search websites compile whatever data they can buy. They often can’t distinguish between two people with the same name, may show records that were dismissed or sealed, and frequently miss county-level cases entirely. A licensed investigator verifies identity, checks the actual court records, and tells you what the records do and don’t show.

Done Lawfully and Confidentially

We follow California and federal law on how criminal history may be obtained and used. The person we’re checking is never contacted and never knows. For employment and tenant screening, see our Background Checks page.
