What is meant by the exclusion of partners? When a person is a partner in a field that is not required to be divided , even though he alone benefits from the entire field for several years, the field is still presumed to be owned by both of the partners. If, however, it is large enough to be divided and only one of the partners benefited from it in its entirety for the years necessary to establish a claim of ownership, he establishes such a claim. For he may tell his partner: "If it is true that you did not sell or give me your share of the field, why did I alone benefit from the entire field? Why did you remain silent and not protest for all these three years?" Similarly, when a man who had stipulated that he waives the right to benefit from his wife's property nevertheless derives benefit from his wife's property for the number of years necessary to establish a claim of ownership, the fact that he derived benefit is of no consequence. This applies even when - while she was consecrated but not yet married - he stipulated that he would not inherit her property, and afterwards derived benefit from it, built or destroyed structures on it, doing whatever he desired. Similarly, when a woman derived benefit from her husband's property and made use of it as she desired for several years, the fact that she derived benefit is of no consequence. This applies even if her husband designated another field for her to derive her livelihood from, and she benefited from other fields. Similarly, when a son receives his livelihood at his father's home and is considered one of the members of his household, if he benefits from his father's property for the number of years necessary to establish a claim of ownership, it is of no consequence. The same law applies when the father derives benefit from the property of this son, who derives his livelihood from him for the number of years necessary to establish a claim of ownership.
