He returns to Sports, initially on loan, just weeks after taking on a coaching role at Nyewood Lane.
The 32-year-old played for Eastbourne in the 2011/12 season after joining from Horsham.
He returned to the Hornets and then had his first spell with Bognor in January 2015.
A short spell with Lewes and a second stint with the Rocks preceded a couple of years as player/assistant-manager back at Horsham.
Charman`s experience, coupled with his versatility will be an asset to the club over the coming weeks.
Charman goes straight into the squad for tomorrow`s fixture at Hampton & Richmond Borough.
