The three years mentioned in the previous chapter must be from day to day. Even if one day was lacking, a claim of ownership is not established and the person in possession of the property is removed from it.
When does the above apply? With regard to landed property that produces benefit at all times - e.g., houses, courtyards, cisterns, pits, storage cavities, stores, inns, bathhouses, dovecotes, olive presses, fields that are continually irrigated and hence can be used for sowing and for planting, gardens, and orchards, and also servants who go on their own initiative, as we have explained.
Different rules apply with regard to a field that is watered only from rain and a grove of trees. The "threes years" are not calculated from day to day.
Instead, after the person in possession partakes of three harvests from one type of produce, it is considered as if three years have passed.
What is implied? There was a date grove and the person in possession harvested it three times, a grape orchard and he harvested it three times, or an olive grove and he harvested it three times, he is considered to have established a claim of ownership. This applies even if the trees were planted one after the other, and there was not enough space left between them. Although ultimately, they will dry and have to be uprooted, since the person derived benefit from them for three harvests, he has established a claim of ownership.

If a person brings witnesses who testify that he dwelled in this courtyard for three years or rented it out to a tenant for three years, he establishes a claim of ownership.
If the owner of the courtyard claims: "Maybe you - or your tenant - did not dwell there during the day and during the night," his claim is valid. We tell the person in possession: "Bring witnesses that throughout these years, you dwelled there during the day and during the night, or depart."
Even when witnesses come and testify, saying: "The person in possession rented the field to us, and we dwelled there during the day and during the night," if the owner of the field demands: "Let them bring witnesses that they dwelled there during the day and during the night," these tenants must bring proof that they dwelled there at all times. The rationale is that the matter is dependent on them and is not dependent on the claim of the person in possession of the property that they should testify on his behalf.

Different laws apply if the person in possession of the property or the witnesses were traveling salesmen who journey from village to village or the like. In such a situation, the court makes a claim on behalf of the owner at the outset. When he brings witnesses to try to substantiate his claim of ownership, the court tells him: "Bring witnesses who will testify that you manifested possession during the day and the night."
When does the above apply? With regard to courtyards, houses, and the like, in which people live during the day and the night. Different laws apply with regard to stores operated by merchants and the like, in which people dwell only during the day. In such a situation, if a person dwelled in the store for three years during the day, he establishes a claim of ownership.

The three years mentioned must be consecutive, one following the other. If a person in possession of a field sowed it one year and left it fallow the next year, and then sowed it one year and left it fallow the next year, he does not establish a claim of ownership. This applies even if he followed this pattern for many years.
If the custom of the farmers of that area was to leave fields fallow, the person is considered to have established a claim of ownership. This applies even if some of the local farmers sow their fields year after year, and some sow their fields for one year and leave them fallow the next. For the person in possession may claim: "I left it fallow only so that it will produce more in the year that I sow it."

When two partners maintained possession of a field for six years, one partaking of the produce in the first, third and fifth years, and the other partaking of the produce in the second, fourth and sixth years, neither is considered to have established a claim of ownership. The rationale is that the owner of the field can say: "Since I neither saw nor heard of one person maintaining possession year after year, I did not protest."
Accordingly, if these partners composed a legal document attesting to their partnership and stating that they should each utilize the field in successive years, if three years pass in which they use it, they establish a claim of ownership. The rationale is that a legal document becomes public knowledge. Hence, if the owner did not protest, he forfeited his right.
Similar laws apply if two people maintain possession of a servant and use his services year after year. Ordinarily, they do not establish a claim of ownership. If they compose a legal document concerning the servant, they do.

The following rules apply when a person who took possession of a property derived benefit from its produce for one year and then sold it, the purchaser derived benefit from its produce for one year and then sold it, and the second purchaser derived benefit from its produce for a year. If they sold it to each other with a deed of sale, the activities of the three are combined and a claim of ownership is established, because the previous owner did not protest.
If they did not record the transaction in a deed of sale, a claim of ownership is not established, because the original owners can say: "Since one person did not maintain a presence within it for three years, there was no necessity to issue a protest."

When a father derived benefit from a property for one year, and his son derived benefit for two years, or the father derived benefit for two years, and his son derived benefit for one year, a claim of ownership is established.
The same law applies if the father derived benefit for a year, the son derived benefit for a year, and the person who purchased it derived benefit for a year, provided that he purchased it with a deed of sale.

When a person seeking to establish a claim of ownership partakes of produce from a field for one year in the presence of the father who was the owner, and two years in the presence of his son, or two years in the presence of the father and one year in the presence of the son, a claim of ownership is established.
Similarly, a claim of ownership is established when the person in possession of the field partakes of its produce for one year in the presence of the father, one year in the presence of the son, and one year in the presence of a person who purchased the field from the son. This law applies when the son sold the field together with all his fields. In such an instance, the person in possession of the field will not appreciate that it was sold, and hence will not necessarily be careful to maintain possession of his deed of acquisition beyond the three-year period. If, however, the son sold the field as a discrete entity the property is expropriated and given to the purchaser. For there can be no greater protest against the squatter's possession than this.

If the person in possession left the field fallow year after year - even for many years - since he did not derive any benefit from it, he does not establish a claim of ownership.
Similarly, if he irrigated it or even irrigated it and did no more than break up large clumps of earth, since he did not benefit from its produce, he does not establish a claim of ownership.

If the property in question was a stone or a rocky area unfit to be sown, the person in possession must benefit from the land in an appropriate manner - e.g., use it to spread out fruits to dry, as a place for an animal to pasture, or the like. If he does not derive benefit throughout all these three years in an appropriate manner, he does not establish a claim of ownership.

The following rules apply when a field is surrounded by a fence and a person took possession of it and sowed crops outside the fence, deriving benefit from the portion that is not protected. Even though he derives benefit year after year, he does not establish a claim of ownership. The rationale is that the owner can claim: "Since we saw that he was sowing crops in a place that was unprotected, we said: 'Whatever he sowed, the beasts of the field will eat. Therefore, we did not protest.'" This law also applies to anyone who sows crops in a place that is not protected and the crops are accessible to animals and other people.

When the person in possession derives benefit from the entire property with the exception of one portion fit to sow a quarter of a kav of grain, he establishes a claim of ownership over the entire field, with the exception of the portion from which he did not benefit. Even if that was a rocky portion in the midst of the field, since he did not use it in a way appropriate for it, he does not establish a claim of ownership over it.

The person in possession of the land receives the remainder of the land.

The following laws apply when there are 30 trees within a tree grove large enough to sow three se'ah of grain. If a person in possession benefited from ten trees in the first year, ten in the second year, and ten in the third, he establishes his possession over the entire grove.
The above applies when the ten trees from which he benefited were spread through the entire area of the field, and the other trees did not produce any fruit. If, however, the other trees produced fruit and he did not partake of it, he establishes a claim of ownership only on the produce from which he partook.
