Running for office in Foster County, North Dakota.

The short version.

A plain-language guide to how county ballot access works in every one of North Dakota's 53 counties. Candidate filing for the 2026 cycle already closed (petitions were due by 4 p.m. on April 6, 2026) and the June 9, 2026 primary already happened, but North Dakota's county races carry something no other state in this series does: a write-in candidate does not have to file anything at all for the vote to count on November 3, 2026. This guide covers that standing write-in rule, the general election itself, and the next regular filing window most county offices will use in 2028. It also carries your county's Auditor, the office that runs the election and accepts every candidate filing.

North Dakota is the only state in the country with no voter registration at all -- residents show up with valid ID and vote. What the state does keep is a central voter file built from driver's license, court and health records rather than registration forms, and a County Auditor in every county who runs elections, generates the pollbook, and accepts every county candidate's filing. Six county offices are elected directly: County Commissioner, County Auditor, County Treasurer, County Recorder, County Sheriff and State's Attorney, though many counties combine two or three of them -- Auditor/Treasurer, Treasurer/Recorder/Clerk of District Court, and similar pairings all exist somewhere in the state -- depending on that county's own structure. Every county-level contest is non-partisan.

This page covers that for Foster County and points you at your local election office for anything specific to your county. It is not legal advice; the official rules live with your election office and the North Dakota Secretary of State.

North Dakota election calendar (2026).

North Dakota runs one statewide primary and general election calendar for every county. The dates below cover the 2026 cycle -- already closed except for the general election and the county write-in door, which never closes -- plus the next regular filing window most county offices are expected to use ahead of the 2028 primary.

Status as of October 18, 2026. Dates that have already passed are greyed out and marked CLOSED.

• Fri Jan 2 - Mon Apr 6, 2026CLOSED. Candidate filing window for 2026 county offices -- already closed. Petitions could not be circulated before Jan 1, 2026; the completed Petition/Certificate of Nomination was due at the County Auditor's office by 4 p.m. on the 64th day before the primary (N.D.C.C. Sec. 16.1-11-06 and 40-21-07).
• Tue Jun 9, 2026CLOSED. North Dakota's 2026 primary election -- already held. County races are non-partisan; the top two vote-getters for each seat advanced to the general.
• Tue Nov 3, 2026North Dakota's 2026 general election -- still ahead. Write-in votes for county office count with no certificate ever required (N.D.C.C. Sec. 16.1-12-02.2).
• Expected early Jan - early Apr 2028Best estimate for the next county-office filing window, based on the standing 64-days-before-the-primary formula against North Dakota's 2028 primary (2nd Tuesday in June, expected June 13, 2028). The Secretary of State has not yet published the official 2028 calendar; confirm the exact date with your County Auditor closer to the cycle.

These filing rules are set statewide by the North Dakota Century Code, but the exact offices on your county's ballot, and whether any are combined into one office, varies by county -- confirm both with your County Auditor before relying on any date here.

Offices on the ballot in Foster County.

North Dakota's counties elect their own slate of non-partisan officers: a Board of County Commissioners plus, depending on the county's structure, an Auditor, Treasurer, Recorder, Sheriff and State's Attorney. The County Auditor, listed for every county below, is the filing officer for every county and multi-county race and administers the county's elections.

• County Commissioner -- governs the county; a 4-year term beginning the first Monday in December after the election. Confirm which seat (if any) is up in a given year with your County Auditor.
• County Auditor -- the filing officer for every county and multi-county office; 4-year term beginning April 1 following the election. Several counties combine this office with Treasurer, or with Treasurer and Tax Director.
• County Treasurer -- 4-year term beginning May 1 following the election. Some counties combine this office with Auditor, or with Recorder, or with Recorder and Clerk of District Court.
• County Recorder -- 4-year term beginning January 1 following the election. Some counties combine this office with Clerk of District Court, or with Treasurer.
• County Sheriff -- 4-year term beginning January 1 following the election.
• State's Attorney -- the county's prosecutor; 4-year term beginning January 1 following the election.
• Clerk of District Court -- in many counties this office is combined with Recorder or Treasurer rather than elected on its own; confirm with your County Auditor whether your county fills it separately.

Exactly which of these offices your county elects on their own, and which are combined -- Auditor/Treasurer, Treasurer/Recorder/Clerk of District Court, and similar pairings all exist somewhere in North Dakota -- depends on that county's own structure. All county-level contests are non-partisan. The County Auditor is the filing officer for every county and multi-county office and the right first call for anything this page does not answer.

How to get on the ballot.

North Dakota offers one route onto the county primary ballot -- a Petition/Certificate of Nomination, with no monetary filing fee -- plus a write-in option for the general election that, unlike a run for Congress or the Legislature, requires no filing whatsoever. The 2026 petition window has closed, but the write-in door for the November 3, 2026 general election has never been closed and never will be.

Petition/Certificate of Nomination -- no filing fee, already closed for 2026.

North Dakota county offices carry no monetary filing fee. Instead, a candidate files a Petition/Certificate of Nomination signed by at least 2% of the electors who voted for that office at the last election (no more than 300 signatures required), plus an Affidavit of Candidacy and a Statement of Interests, with the County Auditor (N.D.C.C. Sec. 16.1-11-11). Petitions could not be circulated before January 1, 2026, and the completed filing was due at the County Auditor's office by 4 p.m. on Monday, April 6, 2026 -- the 64th day before the June 9 primary. That window has closed.

Write-in candidates -- the door that never closes for county office.

Unlike a run for Congress, the Legislature or a judgeship, a write-in candidate for a county, multi-county, city or school-district office in North Dakota is not required to file anything at all for the vote to count (N.D.C.C. Sec. 16.1-12-02.2; N.D.C.C. ch. 16.1-12). There is no certificate, no deadline and no fee -- if enough voters write your name in on November 3, 2026, it counts.

Statutory references: N.D.C.C. Sec. 16.1-11-11 (Petition/Certificate of Nomination for county office needs signatures equal to 2% of the votes cast for that office at the last election, capped at 300 signatures -- no monetary filing fee) · N.D.C.C. Sec. 16.1-11-06, 16.1-11-15, and 40-21-07 (candidate filing opens Jan. 2 and closes 4 p.m. on the 64th day before the primary election) · N.D.C.C. ch. 16.1-12, Sec. 16.1-12-02.2 (a write-in candidate for county, multi-county, city, or school-district office need not file anything for the votes to be counted) · N.D.C.C.

Sec. 11-10-04 (qualifications for county office) and ch. 16.1-11 (county office nominations) · N.D.C.C. Sec. 16.1-02-15 (a voter list or report generated from the central voter file may be made available to a candidate, political party, or political committee for election-related purposes; it may not be sold or redistributed for a purpose that is not election-related). Fees and signature counts change; confirm before you file.

The Foster County Auditor.

North Dakota's county ballot access runs through a petition, not this office -- but the County Auditor below actually administers the election, accepts every candidate filing and petition, and generates your precinct's pollbook from the state's central voter file.

Common questions.

After you qualify: the field operation.

North Dakota's mix of dense river-valley cities like Fargo and Grand Forks and vast, thinly populated prairie counties means turf looks very different county to county -- some races are won door to door in a compact county seat, others cover many miles between farmsteads where a phone call reaches a supporter faster than a knock ever could.

That is the part Motion51 was built for. You scope your district, cut turf, and send volunteers out with a phone instead of a clipboard. It works offline, so canvassing does not stop where the cell signal does, and every door is logged with a timestamp for your records. Our For Candidates page walks through what that looks like.
