About Us
Experience You Can Rely On. Service You Can Trust.
Since 1992, Day and Night Process Service has been committed to one thing — getting the job done right.
With over 75 years of combined legal experience and more than 300,000 legal papers successfully served throughout Wyoming and Montana, we understand what’s at stake every time a document is placed in our hands. Deadlines matter. Accuracy matters. Compliance matters.
And we treat it that way.
Professional Service Rooted in Experience and Responsibility.
A large portion of our work comes from repeat clients and referrals — attorneys, landlords, and businesses who rely on us because they know we deliver legal papers with professionalism and accountability.
Some serves are straightforward. Others require persistence and investigative support.
We provide subject location and private investigation services tailored to completing the service successfully. With strong access to nationwide records, we’re often able to find those who have fallen off the grid or are actively avoiding service.
We don’t just serve papers. We help move cases forward.
Serving Wyoming. Expanding Across Montana.
We provide statewide coverage across Wyoming and now serve major Montana cities, including:
