Harry and Meghan have appointed Sara Latham to be their new Communications Secretary once they split from Kensington Palace in the Spring.
The breakup of the royal household has received the support of Harry and William's father Prince Charles as well.
The news that the royal couples were planning to break up their joint "court" at Kensington Palace was first reported late a year ago.
Earlier on Thursday, it was revealed that the Duke and Duchess of Sussex would be splitting "households" with the Duke and Duchess of Cambridge.
In a statement, the Palace said the changes for the Sussexes "will ensure that permanent support arrangements for The Duke and Duchess' work are in place as they start their family and move to their official residence at Frogmore Cottage".
The Duke and Duchess of Sussex are to have their own household to take forward their growing roles as senior members of the royal family.
What also remains top secret is just how long Meghan will remain on maternity leave.
Latham, the new head of their communications team, has an impressive track record, having previously worked for Bill and Hillary Clinton.
But there has been some speculation that Meghan could decide to have her child at the NHS-run Frimley Park Hospital in Camberley, Surrey, which is much closer to their new home when they move to Frogmore Cottage in Windsor.
But one thing we know for sure is that Prince Harry will be by her side every step of the way and is even planning on taking a few weeks off himself to spend with baby Sussex once he or she arrives. "They have a very clear idea of what they want to do and the instructions from the top and, of course, that comes from Prince William at Kensington Palace, they don't want others treading".
