Family-related Maryland background check resources are limited as all vital records are kept confidential for 100 years unless you happen to be a closely related family member. You can order copies of birth, death, marriage or divorce records for someone else if that is the case. There is a fee for each search you do, and you have to contact the Vital Records office in Baltimore.
A criminal background check is also a difficult process for the average person. As a Maryland background check resource, it can only be utilized this if you are an authorized employer looking to do a check on a potential employee. These records are accessed through the Department of Public Safety and Correctional Services, and each search will cost around $20. You may have better luck with court records that are available online via the Maryland Court Records website.
