Newly crowned Player-of-the-Year Matt Holland is one of seven Charlton players waiting to learn whether they will be offered new contracts.
The 34-year-old long-serving club captain is joined by Chris Powell, Ben Thatcher, Kelly Youga, Cory Gibbs, Osei Sankofa and Svetoslav Todorov whose existing deals expire in July.
Charlton have offered contracts to Medway based goalkeeper Rob Elliot and left-back Grant Basey while Maidstone's Scott Wagstaff and Chris Solly from Medway have become the club's newest professionals.
Meanwhile, Charlton could name Peter Varney's successor as chief executive by the end of the week.
