Before Marriage
While not seen often, some couples date or court each other before a potential marriage, such as Jabra, who dated Gatherine before she broke up with him.

In most cases, two people will plan to get married should one propose it and the other agrees. Particularly notable for marriage proposals is "Marriage Proposal Lola", who is known to have proposed marriage to people 4456 times. Each time, she has been rejected, though she continues this behavior to the point of even proposing to the same person multiple times.

In contrast, Baby 5 is notorious for accepting every marriage proposal due to feeling needed by her fiances, even though all of them actually intended to use her. She also accepted Sai's proposal despite the two having barely known each other, although Sai's proposal had much more noble reasons. Sanji also proposed marriage to Charlotte Pudding, although they were already arranged to be married and he only did it in order to put himself at peace with this path. Boa Hancock has repeatedly proposed marriage to Luffy, but he always rejects her advances. She is sometimes prone to viewing some of his actions as marriage proposals when they are not.

Arranged Marriage
In some cases, marriage is not initiated by mutual choice between the two partners, but rather is arranged by someone else, oftentimes the parents of one or both of the engaged. This is common between royal families, as heirs are often expected to marry someone else of royal descent. They may be granted some choice in the matter, as Nefeltari Vivi was given a large number of princes to choose from, but still have the constraint of having to choose among royalty.

This is particularly prevalent in the Charlotte Family, as the matriarch Charlotte Linlin marries off her children to people from powerful groups in order to ally her crew with these groups. Many of her children do not particularly like the idea of being forced to marry a stranger, but they accept it due to Big Mom expecting it, especially since most of them fear her. However, some of them end up truly loving their spouses, such as Charlotte Praline and Charlotte Chiffon. Praline and Chiffon are even more devoted to their spouses than they are to their mother. Big Mom takes these marriages very seriously, and, especially if the group she intends to ally with is particularly important, she will react with rage should someone prevent the wedding from taking place. This even extends to her own children, as she was intent on killing her daughter Lola when she ran away from a marriage that could have made Big Mom Pirate King. However, Big Mom is not above staging fake marriages and exterminating the leaders of the group instead if she wants to gain full control over the other party, as she attempted to do to the Vinsmoke Family in order to gain control of Germa 66.

Celestial Dragons frequently force people to be their spouses, with the other person having no choice in the matter due to the Dragons' unparalleled privileges. Celestial Dragons are often known to take multiple partners. Absalom also attempted to force Nami into marrying him by knocking her unconscious, proceeding to immediately take her to a marriage ceremony without her consent.

Marriage Ceremonies
As seen in the ceremonies of Absalom and Nami and Sanji and Pudding, the bride and groom will stand before a priest, who recites wedding vows to them. After the vows, the marriage will officially be sealed with a kiss of oath, although in both of those cases the kiss and marriage never happened; the couple will not be considered married until the kiss is performed. During Sanji and Pudding's wedding ceremony, the two of them were together before the ceremony started, which is uncommon in many real-world ceremonies. In Absalom and Nami's ceremony, Nami was unconscious and a zombie recited the vows for her before forcing her to kiss Absalom, putting their possible marriage into question should the ceremony have been completed.

Like many real-world weddings, religious themes are often present, as a priest was shown to preside over Sanji and Pudding's wedding while Shanks attended a wedding ceremony in a traditional church building. Doves seem to be a common theme as well, as many of them were seen flying by when Shanks attended a ceremony.

Married Life
Traditionally, most married couples live together, and children are commonly born to them, though not all people are born in wedlock.

Sometimes controversy will arise if two people are known to be married, as king Riku Dold III worried would happen if his daughter Scarlett was known to have married the former gladiator and criminal Kyros. Thus, Scarlett had to fake her death and relinquish her royal status, and she and Kyros lived in an uninhabited area in order to keep their marriage a secret (although the citizens already knew, and accepted without saying aloud).

Some marriages are a term for alliances between two parties. In those cases, the married couple will reside on either of the bride or groom affiliated territory, and the parties will be considered allies. Some example are Big Mom marrying off her children to increase the strength of her pirate crew or to satisfy her personals desires.

Ending a Marriage
Usually, most marriages seen so far only end when one of the partners dies, as is traditionally intended. So far, no marriages have ever been seen to end on mutual terms, though have ended with abandonment, as seen when recurring background character Sam's wife was stated to have left him. However, the separation of partners does not always mean the end of the marriage, as Banchina considered Yasopp to be her husband up until she died despite him leaving her to live as a pirate.

Should one partner be significantly more influential or powerful than the other, marriages may also end with the more powerful person outright discarding their partner. Saint Charloss discarded his first through fifth wives, with them not having any say in the matter. Big Mom has also discarded all of her 43 husbands in a similar manner.

There used to be an interesting case with marriages in Dressrosa, back when Donquixote Doflamingo ruled and had people turned into toys. When someone became a toy, everyone they knew forgot about them, and if the toy was married, their partner would never have remembered marrying them in the first place. Examples of this were Milo and his wife, as well as the non-canon Maria and her husband. When Milo returned to human form, he tearfully reunited with his family.

No remarriages have been seen, with the closest equivalent being Charloss attempting to marry Marie after discarding five of his wives, though this marriage never took place.
