On Tuesday, for the second time in a little over two months, former President Donald J. Trump will turn himself in for arrest. But it is unclear how many of the rituals of a normal arrest he will be subject to.

He is expected to be advised of his rights, and a judge will assess whether he has legal representation. Mr. Trump is expected to plead not guilty.

Normally, defendants in criminal cases are fingerprinted and photographed to help identify them. But when Mr. Trump was arraigned on unrelated state charges in New York in April, officials felt a mug shot was unnecessary given the former president's level of fame. They did take his fingerprints, though.

It is possible that either or both steps could happen in Miami on Tuesday, but there has been no confirmation. Mr. Trump also could have to surrender his passport.
