The young woman was killed on November 18, five days after the attacks, in a raid on an apartment in Saint-Denis, north of Paris.
The apartment was where Abaaoud and fellow Belgian-Moroccan Chakib Akrouh, who blew himself up, went to ground after the November 13 attacks.
Aitboulahcen, 26, had found and negotiated rental of the safe house for the two jihadists.
Her mother, sister and brother filed a complaint against persons unknown for terrorism and murder on January 13 with Paris anti-terrorist judge Christophe Teissier.
"I consider that Hasna Aitboulahcen is a victim," the family's lawyer Fabien Ndoumou said yesterday.
"She was under pressure from her cousin who threatened her family and the families of her friends," he said.
Investigators initially mistakenly believed there had been a woman suicide bomber at the Saint-Denis apartment.
However, Aitboulahcen's body was found almost intact in the rubble a day-and-a-half after the police assault, according to a source close to the case.
The lawyer also called for a burial permit for Aitboulahcen, whose body, according to him, is still at the forensic institute in Paris.
"This goes against Muslim rites," he said.
Aitboulahcen played a central role after the Paris attacks that killed 130 people, finding and paying for the hideout in Saint-Denis and leading her cousin to it.
