Kenneth Jackson and Alice Waterman pleaded not guilty to arson charges in the Yosemite Lakes Park area.
The pair went before a Madera County judge on Tuesday.
Both are accused of starting dozens of fires in the foothill community.
Their attorneys are now seeking a change of venue, requesting the pair be tried in Bass Lake, but that's something the prosecution is trying to avoid.
Jackson had been previously arraigned on prior charges, but Tuesday's hearing was for new counts filed against him.
