United Kingdom, June 17 -- Nicholas Brendon left everything he owned to his twin brother Kelton Schultz, according to a handwritten will filed in court.

The Buffy the Vampire Slayer star died in March at the age of 54 following a battle with pneumonia and cardiovascular disease - and now documents have been filed in court suggesting the actor left his entire estate to his sibling.

As part of probate proceedings, Kelton submitted a handwritten note to the court which is to have been scrawled by Nicholas prior to his death. It reads: "My will. Sarah gets nothing. Kel gets everything. He can figure it out."

The note suggests he wanted everything he owned to be given to his brother rather than his ex-girlfriend Sarah Marker.
