Fans will be able to pay their personal tributes to the RDB singer on the memorial page and will be invited to make donations to the Brain Tumour UK charity in his memory.
Speaking about Ral, his brother Manj said: "Kuly was the most creative person I had ever known. I was privileged and honoured to learn everything I know today from him. He was my mentor as well as my older brother and I will always follow the example he set and keep making him proud of me."
Brother Surj added: "He always encouraged people around him to work harder, achieve more and as he would always say… keep breaking the boundaries. His incredible work ethic and legacy will continue to motivate us to move forward and help achieve the dreams he had for RDB and Three Records.
"We thank family, friends and most importantly our fans for helping us get through this tough time. Thank you."
Fellow group member and sister-in-law Nindy Kaur said: "Although Kuly was my brother-in-law I always looked at him as my own brother. He was always fair and never took sides with anyone, he looked at logic and people's feelings and that was the one thing I loved the most about him.
"I'm going to miss Kuly, my biggest fan in the studio, my brother and my decision-making partner."
The eldest of the three brothers who formed the British-Asian bhangra group RDB, Kuly lost his battle with brain cancer on 22 May 2012 in Houston, USA, where he had been undergoing specialist treatment. He was 35.
