Battleground states' recount rules vary widely, here's a look at how they work

Michigan: Michigan law allows candidates to request a recount on the grounds of "suspected fraud or error" within a precinct. The law requires candidates to submit their request - as well as a deposit - for each precinct where they are seeking a recount within six days of the conclusion of the canvassing process.

The recount also must begin within five days of the Nevada Secretary of State's office receiving the request.

North Carolina: Candidates may submit a written recount request if the margin of victory is "less than or equal to half of 1% of the vote, or fewer than 10,000 votes," according to the North Carolina General Assembly. The request must be made by noon on the second business day after the county canvas process concludes.

An automatic recount occurs if a candidate's margin of victory is no more than 0.5% of total votes cast. In this case, a recount submission must be submitted to the Pennsylvania Secretary of State's office no later than 5 p.m. on the second Thursday after Election Day.

Wisconsin: Wisconsin law allows candidates to file a sworn recount petition with the state clerk or local officer, stating both the areas they are seeking a recount in and their basis for requesting a recount. Candidates must indicate belief of mistake or fraud.
