The legality of Fmovies' operations has been a subject of debate since its inception. While it provided a convenient and free way for users to watch movies and TV shows, it did so without obtaining proper licensing agreements. Copyright holders argued that Fmovies was facilitating copyright infringement on a massive scale, leading to lawsuits and legal actions against the platform.

In 2018, the U.S. Government included Fmovies in its list of "notorious markets" for piracy, further increasing the pressure on the platform. Over the years, multiple domain seizures and legal actions have resulted in the shutdown of various Fmovies-associated websites. However, the platform's ability to quickly adapt and reemerge under new domains has made it a resilient player in the online streaming world.
