Melania Trump, the former and incoming first lady, will not accompany President-elect Donald J. Trump to the White House on Wednesday, a person briefed on the plans said.

Mrs. Trump had been invited by the current first lady, Jill Biden, for a traditional meeting between the incoming and outgoing presidential spouses as President Biden hosts Mr. Trump at the White House.

But Mrs. Trump is declining the invitation, the person said, rebuffing a tradition that’s part of the transition of power.

An aide to Mrs. Trump did not respond to a message about her plans.

Mrs. Trump sometimes eschewed tradition in her first stint in the White House. She has not yet outlined how she plans to go about the role in the next administration.

She has frequently been in New York as the president-elect’s youngest son, Barron, attends college there. In 2017, she didn’t move to Washington for several months while his school year was going on.
