Investigating in Seattle

The Space Needle is one of the most identifiable landmarks in Seattle and a 1962 World’s Fair legacy. However, Seattle is more than one landmark. It is Washington State’s largest city and home to Microsoft and Amazon headquarters.  Being surrounded by water and parks make it an enviable place to live and work.

Each city and metropolitan area has a set of complications that make private investigative work a challenge. Seattle is no different, with a dense population and highly congested traffic. Our private investigators know the challenges and have experience navigating surveillance in the area.

A few items to note about investigating in Seattle:

  • Very obstructed sight lines due to proximity of large buildings, vehicles and even foot traffic
  • Large downtown area
  • Heavy traffic, busy intersections and closely spaced intersections and many freeway on ramps
  • Heavy pedestrian traffic, buses, increased use of public transportation
  • Difficult to find parking

Commonly requested investigations and services in Seattle

Marital Issues

Is your husband cheating? Do you need evidence?  A private investigator may be able to provide you with the evidence of infidelity, drug use, gambling, or other illegal/immoral activities. These findings can be utilized to help a court case or initiate action from the Seattle police.

Child Custody/Support

Are you seeking information that can help with your custodial arrangement? Our private investigators perform surveillance to ensure that neglect or abuse is not taking place while the child is in the care of the other parent or caretaker. Custodial investigations may also involve ensuring that the terms and conditions of the arrangement are being strictly adhered to.


Concerned about your loved ones and how well they are being cared for? Our Seattle private investigators are able to perform thorough background checks and conduct surveillance on caregivers for children, seniors, and even pets.
