There's a review I see under almost every historical romance with a bad marriage in it. It goes something like this: Why doesn't she just leave?
It's a fair question to ask in 2026. It was not a question most nineteenth-century women could answer the way we would. When Joanna Shupe's The Gilded Rose comes out on October 13, a lot of readers will meet Caroline, a woman married to a man who is charming in public and cruel at home, and some of them will ask it again.
So here's the short version of the answer, with dates. I write romance set in a harbor town where the law is usually the villain's best friend, and I spend a lot of time reading about this. The rules were stranger and harsher than most people expect, and once you know them, a lot of historical romance makes more sense.
A note before we start: I'm a novelist, not a legal historian. The dates below are the well-documented ones, and the law varied a great deal by place and class. Treat this as a reader's map, not a legal textbook.
What coverture meant
Under English common law, and in the American states that inherited it, a married woman was a feme covert: a woman "covered" by her husband. William Blackstone's Commentaries, published in the 1760s and quoted in courtrooms for a century afterwards, put it bluntly. On marriage, the wife's legal existence was suspended, or folded into her husband's.
In practice that meant a married woman generally couldn't sign contracts in her own name, sue or be sued on her own, or control the personal property she brought into the marriage. Her wages, if she earned any, belonged to her husband. Her furniture belonged to her husband. In many cases, so did her inheritance.
You can see why "just leave" runs into trouble. Leave with what? The coat she was wearing was legally his.
Divorce before and after 1857
Before 1857, getting a full divorce in England, one that let you remarry, required a private Act of Parliament. That was expensive, public and slow, and almost every one went to a man. By the usual count only four women ever obtained one.
The Matrimonial Causes Act of 1857 moved divorce into a new civil court. It was a real change, and it was also unequal on its face. A husband could divorce his wife for adultery alone. A wife had to prove adultery plus something else, such as cruelty, desertion, incest or bigamy. That imbalance stayed on the books until 1923.
Then there were the children. Until the Custody of Infants Act of 1839, a father had near-absolute rights over them. That act, pushed through after Caroline Norton's very public fight with her husband, let a mother petition for custody of children under seven. Under seven. A woman with a ten-year-old faced a much harder choice than leaving a bad man. She'd be leaving her child.
Money, earnings and the 1870 and 1882 Acts
The Married Women's Property Act of 1870 let married women in England keep the wages they earned themselves. The 1882 Act went much further and let a married woman own and control property in her own right, as if she were single.
This is why I think 1880 is such a sharp choice for Lisa Kleypas's Queen of Lombard Street (out October 20). A bank for women in 1880 sits in the gap between those two laws. Women had only recently won the right to their own earnings and still couldn't, as a rule, hold much else independently once married. A woman founding a bank in that window is doing something the law had barely caught up with. You don't need to know that to enjoy the book, but it adds a layer.
Gilded Age New York and the one ground for divorce
Across the Atlantic, New York passed its own Married Women's Property Act in 1848 and widened it in 1860 to cover a wife's earnings. On paper, New York looked progressive.
Divorce was another matter. From 1787 until 1966, adultery was the only ground for a full divorce in the state of New York. Cruelty wasn't enough. Abandonment wasn't enough. A woman could seek a legal separation, which left her still married, still unable to remarry, and still exposed to public scandal, and in the society pages of Gilded Age Manhattan, scandal could cost her almost everything she had.
That's the world Shupe's Caroline lives in. The book is a Beauty and the Beast retelling, but the beast she needs rescuing from is her husband, and the castle is the law.
Why the cage makes better romance
Here's my bias, stated plainly: I think these constraints are the best thing historical romance has going for it.
Contemporary romance has to invent its obstacles. Historical romance inherits them. When a heroine in 1850 falls for the wrong man, the stakes are concrete. Choosing badly could cost her property, children, reputation, and sometimes her safety, and she has very little recourse. That makes every choice she does make count for more.
It also explains why so many historical heroines are quietly brilliant at paperwork. If the cage is made of documents, the women who can read them are dangerous. In my own The Smuggler's Ledger, Eliza Mercer is a bookkeeper who notices that a set of seals has been changed, and the whole book turns on her using the law against the men who wrote it. Agatha Brannock in The Proprietor's Bargain runs a boarding house on her own terms until an official seal arrives at her door and the law moves in, literally, to Room Five. Neither book is about divorce. Both are about women who know exactly how much the rules weigh and work around them anyway.
How heroines get out
Historical romance has a handful of reliable exits, and once you know the law, you can see why each one exists.
The widow. A widow was a feme sole again. She could own property, sign contracts and run a business. There's a reason so many historical heroines are widows. It's one of the few legal positions in which a woman got her name back.
The marriage of convenience. If marriage is a legal arrangement, it can be negotiated like one. Settlements, trusts and pin money were real tools for protecting a bride's property, and romance loves a heroine who reads the contract before she signs it.
Never marrying. Spinsters were free in law and squeezed in practice, and the heroine who keeps her independence and her own house is a type readers keep asking for.
The hero who uses the law for her. The best version of this hero doesn't rescue her. He puts the tools in her hands: the lawyer, the document, the testimony. Then he steps back so she can use them herself.
Getting out the hard way. Sometimes there's no legal exit, and the book is about the cost of leaving anyway. These are the angstiest stories in the subgenre, and The Gilded Rose sounds like one. Read the content warnings, and know going in that the law in the background is real.
The short answer
So, why didn't she just leave? Because for most of the nineteenth century, leaving could mean losing her money, her children and her name, with little legal protection. The heroines who found a way out did it with paperwork, nerve and occasionally a well-placed ally, and the good historical romances are honest about how hard that was.
If you're reading The Gilded Rose or Queen of Lombard Street this month, I'd love to hear whether knowing the law changes how you read them. And if you want a heroine who outmanoeuvres the paperwork, start with The Smuggler's Ledger. Book Three, Ink & Saltwater, is coming December 1, and it has a forged seal or two of its own.
