The lawyer will continue to work on the £100 million inquiry until the end of November, which is two months after he officially quit.
Chairwoman of the inquiry, Professor Alexis Jay said: “He was continuing to be instructed for a short period to conclude the work. I believe it was two months.”
It is thought that Mr Emmerson has received £700,000 in two years as the leader of the inquiry.
The inquiry has had three chairmen quit and is yet to hear any evidence into abuse.
When he quit the inquiry in September, victims said that they were “saddened” by his resignation and some survivors were losing faith in the inquiry.
The inquiry was set up to examine whether public organisations, including the police, had failed in their duty to protect children from sexual abuse.
When he resigned, he said that he was no longer the “right person” for the role.
The MP who sits on the Home Affairs Select Committee, David Burrowes, said: “The impression that comes out of it is that things are are being covered up rather than there being greater transparency.”
Veteran barrister Michael Mansfield has urged the Prime Minister to give the expensive investigation a major overhaul.
