Clinton lawyer Mark Elias said in a post on Medium on Saturday that the campaign will participate in the Wisconsin recount which was initiated by Green Party nominee Stein on Friday.
Elias said the campaign will follow the same approach in Michigan and Pennsylvania if Stein pursues recounts in those states.
Results would need to be overturned in all three of the states to change the outcome of the election. Stein has tweeted that she will do a recount in any state in which the deadline to do so has not passed.
Elias said the Clinton camp had not sought a recount because they "had not uncovered any actionable evidence of hacking or outside attempts to alter the voting technology," however now that a recount has been initiated they will take part "in order to ensure the process proceeds in a manner that is fair to all sides."
The Wisconsin Election Commission said on Friday that the recount will begin late next week after Dr Stein pays the recount fee.
The commission's statement noted that 2,975,313 votes were cast in Wisconsin with 1,404,000 of those going to Trump and 1,381,823 cast for Clinton. The remaining 189,490 votes went to a host of third party candidates.

Elias went to great lengths to note that recounts are extremely unlikely to change the outcome of the election as the number of votes separating Trump and Clinton in Michigan, the closest of the three statesโ, "well exceeds the largest margin ever overcome in a recount," he said.
However, he said the campaign would be involved as a point of principle.
"Regardless of the potential to change the outcome in any of the states, we feel it is important, on principle, to ensure our campaign is legally represented in any court proceedings and represented on the ground in order to monitor the recount process itself," Elias wrote.
President elect Trump released a statement savaging the recount and attacking Jill Stein.
"The people have spoken and the election is over, and as Hillary Clinton said on election night, in addition to her conceding by congratulating me, 'we must accept this result and then look to the future.'"
Trump said the recount is "just a way for Jill Stein to fill her coffers with money, most of which she'll never even spend on this ridiculous recount."
"This is a scam by the Green Party for an election that has already been conceded, and the results of this election should be respected instead of being challenged and abused."
And there is another question, who is Jill Stein? Is she the person she says she is, her political affiliations, her beliefs?
Is she just a sore loser, that all of a sudden can muster millions of dollars for a recount? She got such a small margin of votes, and now she is asking for a recount. Smells vey fishy to me
Enquiring minds want to know. Guess we will have to wait and see
