Besides the Sheriff and the two Registers of Deeds, the Middlesex District Attorney, the Middlesex Register of Probate and the Middlesex Clerk of Courts (which were already part of state government before the abolition of Middlesex County government) are all elected countywide to six-year terms.
Even after the abolition of county government in Middlesex, communities are now granted the right to form their own regional compacts for sharing services.
