In Chapter 4 a plot of land is identified for aquisition.

3. And he said unto the kinsman, Nấ-o-mi, that is come again out of the country of which, selleth a parcel of land, which was our brother Elim-ẽ-lēch’s:

Then one worries about past liens and encumbrances.

5. Then said Bo-ăz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.

So one asks for witnesses to the transaction.

9 And Bo-ăz said unto the elders, and unto all the people, Ye are witnesses this day, that I have bought all that was E-lim’-e-lech’s, and all that was Chi-li-ăn’s and Mäh-lõn’s, of the hand of Na’-o-mĩ.

Instead of gap coverage, the buyer secures the potential claimant to the land through marriage.

10 Moreover Ruth the Moabitess, the wife of Mäh-lon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day.

That’s a wrap on a closing.

The thing is- many countries still rely on insufficiently formal titling of land.
