When a princess married did her father's kingdom belong to her husband? I could not find anything online, this is for a story.?

Depends when your story is set.

In the Middle Ages it was universally accepted that a woman couldn't be a ruler in her own right, and that her husband was her 'master' and he had to obey her. Thus, if a woman inherited a throne or a duchy or a barony, her husband got the title and was the real boss, as a matter of course. That's why fairy tales so often end with the hero marrying the king's only daughter and becoming the next king: these stories are memories of medieval customs.

But things changed at the end of the Middle Ages, partly because by then putting on armour and riding into battle was no longer a primary part of a monarch's role. During the 16th century, sometimes a queen's husband got the top title, sometimes not. When Queen Mary Tudor of England ('Bloody Mary') married Prince Philip of Spain in 1554, he became King of England; but when Mary Queen of Scots married Lord Darnley in 1565, he hoped to become King of Scots but he didn't.

So if your story is set more recently, say anywhere from the 18th century to the present day, your princess's husband (like the husbands of Queen Victoria and Queen Elizabeth II) won't become king, not will he expect to.

It depends on time and place and customs of the land.

A king would retain his realm when his daughter marries, though! If he had sons,or other elder daughters, they would become the next monarch and the realm would remain in his family.

If the daughter was the king's heir, in some places, she would rule her lands independent of her husband, while in others, the husband would become king--it depends on the country's customs at a period in time.

No. Logically if her father had a kingdom, he would be a king and would have need of it.

If his daughter inherited his throne, the kingdom would belong to her, not the son-in-law. If she didn't inherit, it would go to the next in line, usually her brother, or the king's brother if females could not inherit.

If her father was king the kingdom is his! if she becomes queen later the kingdom is hers, nothing to do with the husband at all, in either case.

Very good question. No. If this is real, then first of all, the princess's husband would most likely be royal. European royal marriages have generally been, until recently, with other royal families, so this hypothetical husband would already be royalty. A good example of your question, would be the marriage of Princess Charlotte of Wales and Prince Leopold (Later King Leopold of Belgium) in 1816. At the time Charlotte's father the future George IV was the Prince Regent, and Leopold did not take over as the Prince Regent, nor did he, when George ascended to the throne (though unfortunately Charlotte died of exhaustion in childbirth during 1817, so their marriage didn't make it to when George became king), Leopold did not become king. If you want the Princess's husband to become King, then you have to kill off the father and add a scene, were the Princess convinces her Privy Council, to instead of making her husband Prince Consort, make him King Consort.

Good luck with your story!

P.S. the picture is of Charlotte and Leopold's betrothal! By the way, if you don't already know, betrothals are VERY royal ways to do proposals if you want to add that to your story!

You can do whatever you want in your own story. However, whether a man who married a princess (she would have had to be an only child or the eldest of sisters with no brother) would have become king depended on time and place.

Since customs could vary, and since women have been able to rule in their own right in the West in a number of countries since the Renaissance (beginning with the 15th/16th centuries), then unless you're writing a story about the Middle Ages or, say, the Middle East or East Asia, you can safely confine power to the princess once she becomes the queen. Her husband would hold a lesser title, such as "Prince Consort," as Queen Victoria's husband did. The kingdom would NOT become his.
