A few months after the Battle of Hogwarts:
Narcissa Malfoy strode into her husbands study, her heels clicking.
"Lucius, may I have a word?" she asked her spouse. Lucius gestured to a chair in front of his desk.
"Of course, Narcissa dear. How may I be of service?" he drawled.
"I want out," she said bluntly. Lucius raised a questioning eyebrow. "Of our marriage," Narcissa explained. She stood up and started pacing.
"The war is over. We're safe, and our son is alive and well. Pure-blood society as we know it is being demolished, thankfully. Our parents are dead and buried. There is no reason for us to stay together anymore Lucius."
"What about love Narcissa?" he asked softly. "Do you love me?"
She looked at him tenderly. "Yes Lucius, I do love you, but as a sister loves her brother not as a wife to her husband. We were raised together like siblings and forced into a dynastic marriage we both protested against." Narcissa walked over to Lucius and stroked his hair. "This is our chance to finally be happy," she whispered into his ear.
"What about Draco?" Lucius asked.
"I've already discussed this with him. He's okay with it, and he'll accept our separation if this is what we wish for."
He rested his forehead against her smooth cheek. "Do you really want this?" She nodded. "Then I'll make the arrangements with the solicitor and the Ministry first thing tomorrow morning. Anything that you would particularly like to see in your part of the settlement?"
"The house in Hogsmeade and one of the empty shops in the village, preferably with a large storeroom." Lucius raised his eyebrow again. "I wish to own and operate my own potions store." Narcissa explained as she sat back down. Lucius leaned forward and steepled his fingers together.
"You do realise that Hogsmeade already has an apothecary, quite a successful one if I recall?"
Narcissa curled her lip. "Yes Lucius, you are correct. However, my store will focus on household potions; cleaners, perfumes, soaps, teas, cooking. There is nothing out in the market for the average housewitch. Most potioneers spend their time creating healing potions for St Mungo's or military potions for the Ministry." She crossed her legs and leaned back in her seat.
"I'm good at what I do Lucius. I've been creating lotions and potions for this household for 20 years, including your favourite aftershave and bath oils," Narcissa pointed out.
"I always knew my bathing products were exclusive, but not this exclusive!" he smirked at her. She smirked back.
"I'm going to go pack, I'm leaving tomorrow morning. You will inform me when all the paperwork is ready?" Lucius nodded as she rose to leave. Narcissa gave him a peck on the cheek as she left the room.
"Thank you," she whispered.
The next afternoon saw Narcissa back in her husbands study. Accompanying them were Philbus Derby, the Malfoy family attorney, and Percy Weasley, the representative from the Ministry of Magic who would be dissolving their marriage.
Derby rifled through his briefcase, looking for the correct documents. He gave a triumphant grunt when he found the right folder.
"Okay Mr and Mrs Malfoy, we can start the proceedings," Derby said as he placed a pair of small rounded spectacles on his nose. "Upon the dissolution of the marriage between Narcissa Cygna Malfoy nee Black and Lucius Abraxas Malfoy, the assets belonging to both parties will be divided thusly: To Narcissa Malfoy goes the homestead in Hogsmeade Village, an empty shop belonging to the Malfoys of her choosing, the holiday villa in France, the 2 house-elves known as Flora and Fauna, one-fifth of the contents of the Malfoy family vault which is approximately 1 million Galleons, and her dowry of 2 million Galleons. She also retains any shares she may have in Malfoy Industries. To Lucius Malfoy goes the ancestral Manor, Malfoy Industries, two-fifths of the contents of the family vault which is approximately 2 million Galleons, the apartment in New York City, and the 3 house-elves known as Curly, Frizzy, and Fro. Lucius Malfoy also receives back the 3 drops of his blood given to Narcissa Malfoy on the day of their wedding. Lucius Abraxas Malfoy will hold the final two-fifths of the Malfoy family vault in trust for Draco Lucius Malfoy until his 21st birthday. Mr and Mrs Malfoy, please peruse these documents and discuss the details amongst yourselves." Slightly red-faced, Derby handed the documents to Lucius then promptly sat down and began a discussion with Percy about the legal ramifications of having a cauldron of standard thickness exploding upon a person.
"You have been most generous with me Lucius," Narcissa murmured as she glanced over the paperwork.
Lucius met her eyes. "Are you sure it is enough Cissy?"
She smiled at him. "It is more than enough, I assure you." Narcissa turned to the attorney. "Mr Derby, I'm satisfied with this settlement. Where do I sign?"
Derby pointed at the relevant spots, and she signed her marriage away. Lucius did the same, then gestured for Percy to come forward.
"Mrs Malfoy, if I may have your hand?" Percy asked loftily. Narcissa extended her hand, barely flinching when Percy made a small incision in her palm. He muttered an incantation and 3 drops of blood rose out of her wound. Percy then sliced Lucius's palm, muttered again, and then directed the 3 drops into his wound. He healed their wounds, then handed them a ribbon and a pair of scissors. Narcissa cut the ribbon, and threw the halves into the fireplace.
"Congratulations, you are no longer husband and wife. Ms Black and Mr Malfoy, the Ministry wishes you both happiness in your divorce," Percy intoned, "Have a pleasant day." He shook hands with the newly divorced couple, then made his way to the Floo. Derby also made his farewells with promises of having copies of the divorce sent to the both of them the following day.
Lucius leaned over and gave his former wife a large hug. "Be happy Cissy, and come to me if you ever need anything. We may not be married, but we're still friends."
Narcissa hugged him back. "Of course Lucius, thank you."
She walked to the Floo and grabbed a handful of powder. "See you around Lucius," she grinned at him. He grinned back. She threw the powder and walked into the fireplace.
With a flash, she was gone.
