The Administrative office is functioning in the new Sreepadmam building from 1997. In the present set-up there is no yogam. The ancient families all except Mallisseri have become extinct. On 9th March 1971, the Government of Kerala introduced an Act , known as the Guruvayur Devaswom Act, replacing the Trusteeship by a Managing Committee, nominated by the Hindu Ministers in the State Cabinet. The day-to-day administration is to be looked after by an Administrator appointed by the Government.
