New Hampshire has ten counties, each responsible for designated government services and administrative functions. County officials perform responsibilities established under state law, including managing certain public institutions, maintaining records, and carrying out law enforcement and legal duties.



County government operates separately from municipal and state government. Cities and towns manage many local services, while counties administer responsibilities assigned to them through New Hampshire statutes.



The principal elected county offices include:



<ul class="wp-block-list">
<li>County sheriff: Performs law enforcement and court-related duties.</li>



<li>County attorney: Handles criminal prosecution and related legal responsibilities.</li>



<li>County commissioners: Oversee county administration and designated services.</li>



<li>County treasurer: Manages assigned county financial responsibilities.</li>



<li>Register of deeds: Maintains official property and land transaction records.</li>



<li>Register of probate: An elected office with limited responsibilities following court restructuring.</li>
</ul>



These offices have different legal authorities and administrative functions. Understanding their differences helps explain how county government operates.
