Margot Robbie Name Change: Ackerley Adopted After Nearly a Decade

The Margot Robbie name change is now official on paper. Corporate documents published this week by Companies House, the agency that keeps the United Kingdom's public business records, list the Barbie star as "Margot Ackerley" in filings for LuckyChap Entertainment, the production company she co-founded with her husband, film producer Tom Ackerley. The filing, which the agency received on Monday, updates her listed name from "Margot Elise Robbie" to "Margot Elise Ackerley," according to Page Six, which first reported the Margot Robbie name change on Friday.

The timing is easy to understand once the calendar is checked. Robbie married Ackerley in an intimate ceremony in Byron Bay, Australia, in December 2016, so the paperwork lands just short of their tenth anniversary. The filings note that she has carried the Robbie surname on LuckyChap's corporate records since she was appointed a director of the company in May 2015, a full year before the wedding. In other words, the Margot Robbie name change took nearly a decade to make its way into the official register.

Nearly a decade after the wedding

The couple's history goes back further than the marriage. Robbie and Ackerley met in 2013 while working on the World War II drama "Suite Française," in which Robbie starred and Ackerley worked as an assistant director. They became friends first, then roommates, before the relationship turned romantic. In a 2016 interview with Vogue, Robbie said she had not expected to fall in love with him at all, describing herself at the time as uninterested in relationships until he changed her mind.

The following year, in 2014, the pair co-founded LuckyChap Entertainment with their friends Josey McNamara and Sophia Kerr. The company has since backed some of the biggest films of the past decade, including I, Tonya, "Birds of Prey," "Barbie" and "Saltburn." Robbie and Ackerley welcomed their first child, a son, in October 2024, rounding out a decade in which both their family and their company grew steadily. Against that backdrop, the Margot Robbie name change is simply paperwork catching up with life.

Fans should not expect any change at the movies. Robbie is expected to continue using her maiden name professionally, so the name on posters and credits will stay the same. The quiet way the Margot Robbie name change surfaced, through a routine corporate filing rather than any announcement from her representatives, fits the couple’s low-profile style. The updated surname appears only in the corporate filings, where legal accuracy matters more than star recognition. For readers keeping score, the Margot Robbie name change is a legal formality rather than a public one.

The couple has stayed famously private through all of it. They rarely discuss their relationship in interviews, and when they do, the details tend to be small and domestic. The Times of London reported in 2024 that the one thing they argue about at home is whether Tim Tams or Penguins are better, the Australian and British chocolate biscuits from their respective home countries. That kind of ordinary detail is about as much public access as the pair ever gives.

What LuckyChap has coming next

The company at the center of the Margot Robbie name change filing has a busy slate ahead. LuckyChap is developing a live-action version of "The Sims," an "Ocean's Eleven" prequel directed by Bradley Cooper, and a "Sleepy Hollow" adaptation starring Sydney Sweeney, according to Page Six. Any of those projects would extend the company's run of splashy, filmmaker-driven productions that started with I, Tonya and peaked with "Barbie."

Put together, the story is simple. A decade after a quiet Byron Bay wedding, the Margot Robbie name change finally reached the paperwork. The actress will keep the name the public knows on screen while the filings reflect the name she shares with her husband. After nearly ten years of marriage, one child and a production company built together, the update feels overdue rather than surprising. Even so, the Margot Robbie name change gives fans one more detail about a couple that keeps almost everything else to itself.
