8:29 AM PT -- Drew Findling, the attorney representing Takeoff's mother, tells TMZ ... "Along with Atlanta attorneys Pete Law and Mike Moran (as Georgia attorneys we will be filing the requisite paperwork to be admitted pro hac vice in this case) and Houston attorney Ron Estefan, it is our honor to represent Ms. Titania Davenport in bringing this necessary lawsuit."
"With great specifics, the petition lays out the reasons for the filing of this lawsuit. Kirshnik was a gentle soul, whose loving nature and incredible musical talents made him not only beloved by his family and friends, but by his fans throughout the world. He is sorely missed, and we are committed to vigorously fighting on behalf of his memory and his loving mother."
Takeoff's mother Titania Davenport has filed a wrongful death lawsuit against the Houston venue where the Migos rapper was shot and killed on November 1.
According to the court docs, obtained by TMZ Hip Hop, Davenport claims the companies behind 810 Billiards & Bowling failed to take appropriate security measures to protect guests at the venue ... including her son, Takeoff.
The suit, filed Wednesday in Harris County, Texas also cites the lack of security prechecks while knowing Takeoff's celebrity would draw a huge crowd.
Patrick Xavier Clark, the man police say fired the fatal shot that killed the 28-year-old, isn't named in the suit ... but Davenport alleges 810 should have known there was a risk of violence based on past incidents on the premises and the crime in the surrounding area.
Takeoff had a huge memorial service inside State Farm Arena in his hometown Atlanta and the suit is seeking over a million dollars in damages to cover his funeral expenses, mental anguish, and more.
