Some things are not explained in detail because it is written to a people who would already understand certain details of daily life and cluture at the time it was written. Taking a wife included the elaborate ceremonies, written contracts and even financial exchanges in every culture but in the Jewish cultural the various details are alluded to here and there throughout the scripture. Thus when it mentions marrying all those details are assumed. You have some of the examples in Jesus parables. No explanation is given to all of the details of a Jewish wedding is given because it is assumed that the readers of the time already understood how all of these things worked. However if you want to know more you can read the many details that were written in rabbinical writings and other extra biblical resources that have survived and these give us more information.
One thing we know is that marriages in ancient Jewish history were always recorded in writing, there were contracts and there were witnesses and the records were kept in the temple. Matthew and Luke were able use the temple records to support their genealogies. Later in 70 AD these records were lost in the destruction of the temple and the scattering of the Jews.
Using the bible as your source for the "history of marriages" would support that a written contract recorded with the civil leadership was required. Using the Bible as your source for the history of marriage would be using the Jewish traditions that Jesus used for parable sources such as friends waiting for the Groom to come along so they could join in a parade with lighted lamps, wedding feasts that required certain things from the guests, Fathers giving brides to grooms, dowries, contracts, and other things that you can find in historical writings and rabbinical writings.
This information is enough to completely rule out the idea that two people can go mate under a tree in the forest and say a prayer and not be guilty of fornication.
Moving in together and claiming monogamous sex the same as marriage because God knows your heart is a lie. It's fornication.
And all the promises and claims of being married before God will be ignored by God in the day of judgment.
He will say to that person "how came you here without a wedding garment friend" And then cast them out.
They will be speechless because they knew this would happen but decided to chance it anyway thinking that their pitiful excuse "we were married in our hearts" would allow them to slide by. But in that day their false heart of compromise will be manifest even to themselves and they will be speechless and not even try to offer the lame excuse that they knew wasn't going to fly anyway.
And truth be told in that day there will be many other sins and false confessions of faith manifest to them besides the fornication. Those who are willing to compromise with the marriage rules are always full of many other compromises as well. Holiness is not as important to them as it must be to be saved.

As I was reading the post I thought about in Deuteronomy how it talks about issuing a certificate of divorce--so I thought well, then that means they must have had a certificate of marriage--in any case I found this article which was really interesting about Ancient Jewish Marriages--this is an excerpt from it:
"the
Book of Deuteronomy specifically states that if a man dislikes his wife, “he writes her a bill of divorcement and gives it in her hand” (24: 3). Modern critics of the Bible have agreed that on the whole, the Deuteronomic law is a product of the century preceding the Babylonian exile. If a written document was employed at that period in dissolving a marriage, we have to assume that it was also employed in contracting a marriage."
"At the beginning of the 20th century, an actual Jewish marriage record during the period of the return from the Babylonian exile was discovered — the oldest marriage contract in Jewish history. The marriage did not take place in Palestine or among the exiles in Babylon, but among the Jews of Elephantine and Aswan, at the southern border of Egypt.
The marriage contract of Mibtachiah [the bride] and As-Hor [the groom] began with a declaration of marriage by As-Hor to Mibtachiah’s father. “I came to thy house for thee to give me thy daughter, Mibtachiah, to wife; she is my wife and I am her husband from this day and forever.”"
Betrothal and the Wedding
Until late in the Middle Ages, marriage consisted of two ceremonies that were marked by celebrations at two separate times, with an interval between. First came the betrothal [
erusin]; and later, the wedding [
nissuin]. At the betrothal the woman was legally married, although she still remained in her father’s house. She could not belong to another man unless she was divorced from her betrothed. The wedding meant only that the betrothed woman, accompanied by a colorful procession, was brought from her father’s house to the house of her groom, and the legal tie with him was consummated.
This division of marriage into two separate events originated in very ancient times when marriage was a purchase, both in its outward form and in its inner meaning. Woman was not recognized as a person but was bought in marriage, like chattel.
Marriage, as with any type of purchase, consisted of two acts. First the price was paid and an agreement reached on the conditions of sale. Sometime later the purchaser took possession of the object. In marriage, the mohar was paid and a detailed agreement reached between the families of the bride and groom. This betrothal was followed by the wedding, when the bride was brought into the home of the groom, who took actual possession of her.
In those days the betrothal was the more important of these two events and maintained its importance as long as marriage was actually based upon a purchase. But as women assumed more importance as individuals, and marriage ceased to be a purchase, attaining moral significance, the actual wedding became more important than the betrothal.
