Whitney Houston and Bobby Brown had a prenuptial agreement drawn up before they got married.

The late singer - who passed away last month at the age of just 48 - signed the document on July 17, 1992, and as well as banning him from accessing her will, it stated the income both parties earned during their marriage would remain separate property.

"Houston shall have the right to dispose of her Separate Property by Last Will and Testament in such manner as she may, in her own uncontrolled discretion deem proper. All future earnings, income, and accumulations resulting from each of the party's respective personal activities, skills, efforts and work (including but not limited to each party's respective earnings, income and accumulations derived from recording contracts, movie contracts, other media contracts, concert tours, endorsements, personal appearances....shall remain separate," the agreement read, obtained by RadarOnline.com.

The couple - who had a daughter, Bobbi Kristina, together - filed for divorce in 2006 after 14 years of marriage, but the prenuptial agreement stated the "I Will Always Love You" singer had "no obligation" to support her former spouse.

"Brown agrees that Houston shall have no legal obligation to support him, and that he shall have no right to require the payment of any alimony, support (including temporary support), or other maintenance, and no right to receive any rights, interests, or claims to Houston's property, and Brown hereby waives releases, and forever renounces any and all such rights to the fullest extent permitted by law," it stipulated.

Bobby - who was believed to have introduced Whitney to illegal substances - was banned from attending the star's funeral last month.
