The man and the woman have previously had a relationship.
Among other things, they are accused of being behind a fire in Tångaberg, north of Varberg in May, where a holiday home was completely destroyed.
The accused woman's ex-husband lived in the house next door.
According to the indictment, the suspected perpetrators set fire to the wrong home.
13 different criminal suspicions
At the end of August, the couple is said to have started a car fire in Skällinge and a few hours later set fire to a villa in Älvsered in Falkenberg municipality.
It burned to the ground.
A couple who were awakened from their sleep had to flee the home.
The indictment against the man and the woman contains a total of 13 charges, including attempted murder and attempted aggravated arson.
Both deny the crime.
An eight-day trial begins on May 4.
