A divorce coach who charges $2,500 a session to advise women how to leave their husbands has insisted she is not a “marriage wrecker.”

Single Emma Heptonstall ditched her high-flying job as a lawyer and set herself up as a self-proclaimed “divorce alchemist” — teaching mainly women, but occasionally men, how to have “happy splits.”

The 44-year-old said: “I’m the divorce alchemist for ladies who leave. I know some people think I am not in a position to advise, having never been married, but I think that makes me objective.”

“I’m not going to compare my situation with other people’s because I haven’t been in it.”

Heptonstall, who currently lives in York but will soon be moving to West Sussex, admitted most of the women she helped — a staggering 90 percent — were having affairs.

But she says she doesn’t judge her clients.

She added: “The reason that people cheat is because they are unhappy. I don’t sit in judgment. That’s not my job. My job is to coach people through their divorces.”

“While most of the women who are leaving their husbands, about 90 percent are doing so because they have had or are intending to have an extramarital affair, it is not the only reason.”

Heptonstall, who launched her business in January 2015, has seen it go from strength to strength.

A one-day session with her, with a written action plan, costs $2,500, while a three-month action plan costs double that — and some clients have stayed for as long as 12 months.

Her business has proved so successful, she has even written a book.

Called “How To Be A Lady Who Leaves,” it advises people how to have happy divorces and charts her experiences helping up to 30 people — including, on one memorable occasion, a couple, who were seeing her separately.

“I made sure they didn’t discuss what we’d said in sessions to each other,” she explained. “It was confidential, as it is with all my clients.”

University of Keele graduate Heptonstall initially started her career as a magistrates’ clerk before focusing on family law.

She believes her time spent unraveling complex issues — like custody of children — helped prepare her for coaching.

She said: “Lawyers resolved practical issues where people were, understandably, emotional. But lawyers weren’t equipped to deal with the emotional issues.”

She added: “Once I started coaching training and looking at people’s issues emotionally as well as practically, it made for happier divorces. It made me realize there was a market for what I do. That there was something in it.”

Most of her clients end up leaving their spouse — however, a “minuscule” amount have decided against divorce, instead staying together.

She said sessions help people understand whether their problems stem from them or their marriages.

“If they are unhappy with themselves, they will still be unhappy once leaving a marriage,” she said.

Now, Heptonstall is particularly interested in women who have been disempowered during the course of a marriage.

She explained: “So many women I talk to have been disenfranchised during a marriage. They don’t know what their mortgage payments are, how much money they have — things like that.”

“They earn ‘housekeeping money.’ It’s bonkers. It’s 2017. I help them learn about things like that.”

Despite her background and training, Heptonstall said she no longer describes herself as a lawyer — but doesn’t identify as a counselor either.

“I would describe myself as a coach,” she said.

“What I do is very future-focused. It’s about moving on and ensuring happy divorces. I’m not a marriage-wrecker.”
