Do private detectives need a license in Massachusetts?

Does it matter that Lexington is a town?

Only for knowing where to look. The town keeps some local records; deeds go to the county or district registry of deeds; court records are at the county. Investigators plan searches around that structure.

The person I'm concerned about works outside Lexington. Can surveillance follow them?

Yes, within the law. Mobile surveillance can follow a routine into Boston and back, from public places. Plans account for travel time, and work in another state is handled by a detective licensed there.

What should I know before hiring a private detective in Middlesex County?

Most records that matter in Middlesex County are kept at the county level: court files with the clerk, and deeds with the county or district registry of deeds. A good detective searches those originals rather than relying on online summaries, and confirms identity so records aren't attributed to the wrong person.

Often. Locate work combines records research with field verification, wherever the trail leads. Moves along Interstate 95 and connecting highways are common, and investigations are coordinated across state lines with appropriately licensed detectives.

Yes. People rarely stay inside municipal lines. Work that starts in Lexington can continue in nearby communities such as Arlington, Waltham, Burlington, planned as one engagement and carried out by detectives licensed for each place the work goes.
