He will join other representatives from organisations in the capital in signing the London Compact.
The London Compact, which is the mutual fair play agreement outlining how the public and voluntary sectors should behave towards each other, was created in 2003.
Livingstone was among the original signatories. All of those who signed four years ago, plus representatives from organisations that did not, have been invited to a re-signing event at City Hall.
The Government Office for London, the Learning & Skills Council, London Councils, the Metropolitan Police and the London Fire and Emergency Planning Authority are expected to sign for the first time.
