Michael Mone, 46, wanted an interim interdict to keep the lingerie tycoon out of the mansion they jointly own.
They had agreed to each live in the house at Thorntonhall, near Glasgow, in alternate weeks and, it is understood, to cause as little disruption as possible for their three children, either of them could collect clothes while the other was there.
But a visit by Mrs Mone, 42, prompted her ex-husband's legal action.
The move had earlier been rejected and yesterday Sheriff John Millar formally closed the case.
A lawyer representing both Mones told the court they were happy for the matter to be officially dismissed.
Mrs Mone celebrated her birthday yesterday by thanking wellwishers for messages of congratulation.
She said: "Thanks for all your birthday messages, really appreciate it."
The Mones - who were together for 20 years - set up lingerie firm Ultimo and turned it into a multimillion-pound business. But they divorced earlier this year and Mr Mone has now set up another company.
The former couple were not at Hamilton Sheriff Court yesterday.
Mrs Mone recently dropped the asking price on her mansion in Thortonhall by £150,000. But buyers will still have to pay £1.5 million to own the 12-room home the couple shared.
