Arran McManus, 36, was involved in a crash near Lenham on the morning of November 25.
His partner Ashleigh Devlin said Arran was their “best friend and whole life” and a pillar of the local community.
They said: “I am heartbroken to share that on Tuesday morning, Arran, my partner, my soulmate, and best friend was sadly taken too soon from us.
“Arran was our whole life and more. He was the most wonderful dad to our two incredible children, and he was so proud of them both and loved them both so deeply.
“Arran will be sorely missed by his entire family circle. He was a pillar of our local community football club Kennington, as a coach and a member of the executive team where he brought joy to so many.”
The emergency services were called to the crash between a white Mercedes lorry, a black Nissan Qashqai, and a white Scania articulated lorry on the westbound M20 between junctions 9 and 8 at around 8.30am.
