Prince Harry and Meghan Markle's Archewell Foundation has been deemed "delinquent" and has been ordered to stop spending and soliciting money.
The California Registry of Charities and Fundraisers sent a delinquency notice on May 3 to the Foundation.
US publication People reports the document said the organisation was "listed as delinquent with the Registry of Charities and Fundraisers for failing to submit required annual report(s) and/or renewal fees."
"An organization that is listed as delinquent is not in good standing and is prohibited from engaging in conduct for which registration is required, including soliciting or disbursing charitable funds," it said.
"The organization may also be subject to penalties and its registration may be suspended or revoked by the Registry. Once you submit the delinquent record(s), you will be notified of the amount of any late fees that are owed."
A source told People the Archewell Foundation had filed on time, but a cheque that was sent to the Registry was never received.
It is believed a new cheque has been sent via mail and those behind the Archewell Foundation expected the issue to be quickly resolved and reflected in the records within the next seven business days.
The Foundation was set up as a not-for-profit after they stepped back from their royal roles in 2020.
"Archewell Foundation believes that compassion is the defining cultural force of the 21st century and, through its work, Archewell Foundation supports a growing community of partner organizations fuelling systematic cultural change," says a mission statement on the Foundation's website.
"Archewell Foundation listens to people and their communities, helps them to tell their stories, puts real action behind its words, and spotlights a new generation of leadership."
Neither Harry nor Meghan, who are currently on a tour of Nigeria, have commented publicly on the Registry's notice.
