He will be fingerprinted. He will be photographed. He may even be handcuffed.
In the days ahead, Donald J. Trump is expected to walk through the routine steps of felony arrest processing in New York, now that a grand jury has voted to indict him in connection with his role in a hush-money payment to a porn star. But the unprecedented arrest of a former commander in chief will be anything but routine.
Accommodations may be made for Mr. Trump. While it is standard for defendants arrested on felony charges to be handcuffed, it is unclear whether an exception will be made for the former president because of his status. Most defendants have their hands cuffed behind their backs, but some white-collar defendants who are deemed to pose less of a danger have their hands secured in front of them.
Mr. Trump will almost certainly be accompanied at every step of the process — from the moment he is taken into custody until his appearance before a judge in Lower Manhattan’s imposing Criminal Courts Building — by armed agents of the United States Secret Service, who are required by law to protect him at all times.
Security in the courthouse is provided by state court officers, with whom the Secret Service has worked in the past. But the chief spokesman for the agency, Anthony J. Guglielmi, said he could not comment on any specific measures that would be put in place for Mr. Trump.
It may take several days for Mr. Trump to appear at the courthouse. Now that the grand jury, composed of members of the public who heard from witnesses and debated privately, has voted to indict him — meaning to charge him with one or more crimes — the indictment must be handed up to prosecutors.
Then prosecutors would typically contact his defense lawyers to negotiate the terms of his surrender, a common practice in white-collar investigations when the district attorney’s office has been in touch with defense attorneys.
