At the same time, the AG warned the 11 counties that have passed people’s assembly motion, saying they committed illegalities.
Such devolved Houses, he said, may be surcharged for misusing taxpayers’ money.
He said the national government retains the right to review the funds allocated to the concerned counties.
The AG's warning came hours after Mr Odinga told off the US and other western powers that have advised against the oath plan.
The US, Mr Odinga said, should not talk about violation of the constitution as far as his swearing-in is concerned yet Washington DC has been "loudly silent" on killing of innocent protesters by police since August.
Kenya Police stand accused of shooting and killing dozens in violent protests that followed August 8 General Election and October 26 repeat presidential poll.
"We thought we had friends but we were wrong and now we know they are enemies. Up to today, no single ambassador has condemned the killing of people by police," he said.
"The western countries should, therefore, keep off the affairs of the country as Kenyan problems will only be solved by Kenyans themselves."
He spoke at the City Mortuary in the capital Nairobi when he met and condoled with families that lost their loved ones during the post-poll chaos.
