The children and widow of the late Hugh Hefner have some strict rules to follow in order to earn the estate he left behind.

According to PEOPLE, the media mogul made it very clear in the trust to his estate that his children, Christie A. Hefner, David Hefner, Marston Hefner and Cooper Hefner, and his widow, Crystal Harris, are forbidden from abusing drugs or alcohol. If they fail to follow that rule, they may be banned or suspended from inheriting his fortune.

Some of the legal documents in the estate, obtained and published by The Blast, laid it out in black and white:

If the Trustees reasonably believe that a beneficiary of any trust routinely or frequently uses or consumes any illegal substance so as to be physically or psychologically dependent upon that substance, or is clinically dependent upon the use or consumption of alcohol or any other legal drug or chemical substance that is not prescribed by a board certified medical doctor or psychiatrist in a current program of treatment supervised by such a doctor or psychiatrist, and if the Trustees reasonably believe that as a result the beneficiary is unable to care for himself or herself, or is unable to manage his or her financial affairs, all mandatory distributions (including distributions upon termination of the trust) to the beneficiary, all of the beneficiary’s withdrawal rights, and all of the beneficiary’s rights to participate in decisions concerning the removal and appointment of Trustees will be suspended.

Should one of the trustees fail a drug test, they may be suspended from the estate, but their status could be restored “in the case of use or consumption of an illegal substance, examinations indicate no such use for 12 months and, in all cases, when the Trustees in their discretion determine that the beneficiary is able to care for himself or herself and is able to manage his or her financial affairs.”

Hefner reportedly also had a clause in his trust in case a person attempted to claim he or she was one of his children following his death. If Hefner didn’t confirm they were his child when he was alive, they’re not getting any cash.

It was previously reported that Harris would not inherit any of her late husband’s fortune due to an “ironclad” pre-nup. Most of his money was promised to “his children, the University of Southern California film school and a variety of charities,” according to Us Weekly, though Harris wasn’t left empty-handed. Hefner reportedly left her the deed to a 5,900-square-foot Hollywood Hills home and close to $5 million, which was agreed on in the prenuptial agreement ahead of their 2012 wedding.
