As part of those negotiations with prosecutors, the court may also agree to grant him a private entrance to the court, instead of the more typical "perp walk" in front of the assembled media.
Once inside, however, Mr Trump will be fingerprinted and have his mug shot taken like all defendants in criminal cases. He will also be read his "Miranda" rights, reminding him of his constitutionally-protected right to a lawyer and to decline to talk to police.
Defendants charged with a felony are typically handcuffed temporarily, although Mr Trump's lawyers will try to avoid that for their client. Throughout the booking process, he will be accompanied by Secret Service agents.
Mr Trump would then wait in a holding area or cell until his appearance before a judge. The arraignment - the moment where a defendant enters their plea before a judge - is open to the public.
Once the case is booked and a judge is selected, other details will fall into place, such as the timing of the trial and possible travel restrictions and bail requirements for the defendant.
A conviction on a misdemeanour would result in a fine. If Mr Trump were convicted on the felony charge, he would face a maximum sentence of four years in prison, although some legal experts predict a fine is more probable, and that any time behind bars is highly unlikely.Can he still run for president?
An indictment or even a criminal conviction would not prevent Mr Trump from continuing his presidential campaign if he so chooses - and he has given every indication that he will keep pushing ahead regardless of what happens.
In fact, there is nothing in US law that prevents a candidate who is found guilty of a crime from campaigning for, and serving as, president - even from prison.
Mr Trump's arrest would certainly complicate his presidential campaign, however.
While it might cause some Republican voters to rally around their embattled champion, it could be a significant distraction for a candidate on the campaign trail, trying to stump for votes and participate in debates.
It would also deepen and enflame already sharp divides within the American political system.
Conservatives believe the former president is being held to a different standard of justice, while liberals view this as an issue of holding law-breakers - even those in the highest positions of power - accountable.
