Anne Heche died without a will, and her son has filed court papers to control her estate.
Homer Laffoon, 20, Heche's son with ex-husband Coleman Laffoon, filed a petition in Los Angeles Superior Court on Wednesday requesting that he be allowed to administer his mother's estate.
The petition lists Homer and Atlas Tupper, 13, Heche's son with former partner James Tupper, as her only heirs.
The document says the value of the actress's estate is unknown. That is often the case on such initial filings, before anyone has the legal authority to assess the dead person's assets.
Homer also filed a petition asking that someone be appointed to represent his brother's interests in court.
Heche's representative declined to comment on the filing.
On August 5, a car the actress was driving jumped a curb, crashing into a Los Angeles home and bursting into flames. She was declared brain dead on August 11, and was kept alive on life support for three more days so her organs could be donated.
Heche, 53, was among the biggest film stars of the late 1990s, starring opposite actors including Johnny Depp and Harrison Ford, and had worked consistently in movies and television for more than three decades.
She was married to Coleman, a television camera operator, from 2001 to 2009, and was in a relationship with James, an actor, from 2007 to 2018.
