Once-powerful legal scion Alex Murdaugh was formally disbarred in South Carolina on Tuesday — the same day he learned he was going to be charged with murdering his wife and son.

The Supreme Court of South Carolina issued its decision while noting that the disgraced member of one of the state’s most powerful legal families had already admitted a slew of serious crimes, including stealing millions and faking his own murder.

“Based on his admitted reprehensible misconduct, we hereby disbar Respondent Richard Alexander Murdaugh from the practice of law in South Carolina,” the order stated, noting his “myriad criminal charges.”

After first suspending Murdaugh in September, the court summoned him to a hearing last month — one that was canceled when the jailed scion stated that “he did not contest the Court’s ‘authority and decision’ to disbar him from the practice of law,” the order said.

Murdaugh “concedes that disbarment is warranted in light of his admitted professional misconduct,” noted the five justices who signed the order.

Still, the decision was not based on that but the “duty to protect the public from attorneys who are not fit to practice law,” the court stressed.

“Disbarment is among the most serious sanctions this Court can impose for unethical conduct committed by members of the legal profession,” the order stated.

Tuesday’s decision came on the same day that Murdaugh and his family were told that he would be charged with murdering his wife and 22-year-old son.

His lawyer, Jim Griffin, confirmed that the South Carolina Law Enforcement Division told Murdaugh family members it plans to seek indictments from a grand jury later this week. Murdaugh was personally told about the impending charges, sources told NBC News’ “Today” show.

“We won’t have any comment until charges are actually brought against Alex,” said Griffin, who previously admitted his client had always been viewed as the prime suspect for the double slaying.

Murdaugh had been the one to call 911 on June 7 last year, saying he stumbled across the murdered bodies of his wife, Maggie, 52, and their 22-year-old son, Paul, near their sprawling hunting lodge in Islandton.

The pair were shot several times with at least two separate guns — a rifle and a shotgun — but authorities immediately assured the public it was not in danger and never hinted at seeking other suspects.

Through it all, Murdaugh claimed to have a rock-solid alibi, saying he’d been visiting his dying father in the hospital and checking on his mother when the killings happened.

However, two sources told NBC News that investigators have cellphone video that puts him close to the murder scene at the time, contradicting his claimed alibi.

While Murdaugh long denied the murders, the focus led to his downfall with investigations and dozens of charges over his finances — as well as a madcap plot to hire someone to kill him so his surviving son, Buster, could collect $10 million.

Investigators also focused on the mysterious 2018 death at his home of his longtime housekeeper Gloria Satterfield, 57, which was never investigated at the time.

It emerged he’d collected $4.3 million in insurance over that death, which he’d kept secret from her family.

A lawyer for the Satterfields, Eric Bland, told NBC News that he was not surprised that Murdaugh was to be charged with his wife and son’s murders.

“He’s just an extremely dark individual — evil, just raw, basic evil,” Bland said of Murdaugh, who has been behind bars since October.
