A DUI/DWI conviction will appear on a criminal background check requested by a prospective employer, landlord, or licensing authority, for example. Generally, the only way to remove a DUI/DWI conviction from appearing in some or all of such background checks is to have it expunged or sealed—which is only possible in limited circumstances.

In New Hampshire, a DUI/DWI (Driving Under the Influence/Driving While Intoxicated) conviction is a criminal offense and will appear on a criminal background check. This can affect an individual's opportunities when it comes to employment, housing, or obtaining certain licenses. New Hampshire law does allow for the annulment (expungement) of certain criminal records, including DUI/DWI convictions, under specific conditions. To be eligible for annulment, a certain period must have elapsed since the completion of the sentence, which varies depending on the severity of the offense. For a DUI/DWI, this period is generally a minimum of two years for a first offense. However, not all DUI/DWI convictions are eligible for annulment, and the process involves petitioning the court and demonstrating that the individual has been rehabilitated and that the public's interest in having access to the record is not greater than the individual's right to privacy. If the court grants the annulment, the conviction would not appear on most background checks, although it may still be accessible in certain situations, such as for law enforcement or criminal justice purposes.
