ATLANTA, USA (AP) — A lawyer for Whitney Houston said yesterday that her will is a "straightforward" case and expects no complications with the administration of her estate.

Kenny Meisalas said in a phone interview that "things with the family have been very smooth, no problems". He said things are proceeding normally, and he doesn't expect any challenges to the will.

Fulton County Probate Court Judge Pinkie T Toomer in Atlanta on Wednesday approved the will. It revealed the late superstar left all her assets to her only child, 19-year-old Bobbi Kristina. Her sister-in-law and manager, Pat Houston, was named as the administrator of the estate.

Meisalas declined to talk about Houston's assets or possible debts.

Since her death, Houston's albums have been top sellers. This week, she has four albums in the top 20 positions on the Billboard Top 200 albums chart, including her Greatest Hits, which sits at number two and sold 112,000 copies, according to Nielsen SoundScan.
