Every transgression for which one is liable for a fixed sin-offering if he transgressed inadvertently carries liability for a provisional guilt-offering if he is unsure whether he violated it.
What does being unsure mean? If a person is in doubt whether he inadvertently violated this transgression or not, he is obligated to bring a guilt-offering, as Leviticus 5:17-18 states: "If he was unaware and became guilty, he shall bear his iniquity. He shall bring an unblemished ram from sheep, of the given value, as a guilt-offering." This is referred to as a provisional guilt-offering, for it brings atonement when the person is in doubt, tentatively, until he knows with certainty that he sinned inadvertently, at which time, he brings a sin-offering.

A person is not liable for a provisional guilt-offering unless there is a prohibition that is established. What is implied? A person partook of forbidden fat, but was in doubt whether there was an olive-sized portion or not. There was a piece of forbidden fat and a piece of permitted fat before a person and he partook of one of them, but he did not know which one he ate. His wife and his sister were with him at home. He was intimate with one of them, but did not know with whom. Both the Sabbath and a weekday passed and he performed a forbidden labor on one of them, but did not know the day on which he acted. He performed a deed on the Sabbath, but did not know whether it falls into a category of forbidden labor. In all these and similar instances, he should bring a provisional guilt-offering.
If, however, a prohibition has not definitely been established, he is not liable for a provisional guilt-offering. Thus if there was one piece of fat before a person and he was unsure whether it was permitted or forbidden and he partook of it, he is exempt, for there is no established prohibition. Similarly, one who partakes of the fat of a ko'i is exempt from a provisional guilt-offering, for there is not an established prohibition.Similarly, when a man is intimate with a woman who is unsure whether or not she is in the niddah state or we are unsure whether she is an ervah due to family connections, he is exempt from a provisional guilt-offering.
Therefore a man who is intimate with a woman is exempt from this sacrifice, if: a) she finds blood on the examination cloth she uses after time has transpired, or
b) he married his yevamah within three months of his brother's death and she gave birth and it is not known whether the child was conceived by her first husband and was born after a nine-month pregnancy or he was conceived by her second husband and was born after a seven-month pregnancy.Similar laws apply in all analogous situations, for there is no established prohibition.

An individual can be required to bring a provisional guilt-offering in the following circumstances:
a) he who ate a piece of fat and one witness states: "What you ate was forbidden fat," while the other states; "You did not partake of forbidden fat;
b) a woman said that he partook of forbidden fat and another woman said that he did not. Since he does not know whether he partook of the forbidden fat or not and the existence of the prohibited substance has been established, he is obligated to bring a provisional guilt-offering.
Similarly, if one was intimate with a married woman about whom one witness states: "Her husband died," but another states: "He did not die," he is obligated to bring a provisional guilt-offering. This law also applies when there is a question if a woman is divorced, for the prohibition was established.If, however, there is a doubt whether or not a woman was consecrated, one who is intimate with her is not liable, because the prohibition has not been established.

A person is liable for a provisional guilt-offering in the following situations: There were two pieces of fat before him: one forbidden and one permitted. He ate one inadvertently and a gentile or a dog came and ate the second. The gentile or the dog ate the first and a Jew ate the second. One ate the first intentionally and the second, inadvertently, or he ate the first inadvertently and the second, intentionally. In all these situations, he is liable, because the existence of a prohibited substance had been established.
If, however, he partook of both of them intentionally, he is exempt from bringing a sacrifice. And if he ate them both inadvertently, he must bring a sin-offering. If he ate the first inadvertently and another person came and ate the second inadvertently, they are both obligated to bring a provisional guilt-offering. Similar laws apply in all analogous situations.

A transgressor is exempt from bringing a sacrifice in the following situations. There was a piece of forbidden fat and piece of notar before him. He ate one of them inadvertently, but did not know which one he ate. His wife who was in the niddah state and his sister were at home with him. He was intimate with one of them inadvertently, but did not know which one. The Sabbath and Yom Kippur followed directly after each other, he performed a forbidden labor in the twilight between them. He does not bring a sin-offering, because he does not know which transgression he performed, as we explained. Nor does he bring a provisional guilt-offering, because he knows with certainty that he transgressed.

Whenever a person performs a deed that obligates him for one fixed sin-offering when he knows with certainty that he transgressed, he is liable for a provisional guilt-offering if he is unsure whether he transgressed. Whenever a person performs a deed that obligates him for many fixed sin-offerings when he knows with certainty that he transgressed, he is liable for many provisional guilt-offerings, matching the number of sin-offerings, if he is unsure whether he transgressed.
What is implied? Just as a person who ate forbidden fat, blood, notar, and piggul in one lapse of awareness is liable for four sin-offerings,so, too, if he is uncertain whether he partook of them or not, he must bring four provisional guilt-offerings. Similarly, if he is unsure if the woman with whom he was intimate is his wife or so-and-so, another woman who is forbidden to him as an ervah and for whom he would be liable eight sin-offerings if he was intimate with her, he must bring eight provisional guilt-offerings.

When a person ate one of two pieces of fat and he was unsure whether he ate forbidden fat or permitted fat, and after that doubt arose in his mind, he ate another one of two pieces of fat and he was unsure whether he ate forbidden fat or permitted fat, he must bring two provisional guilt-offerings.

Just as the definitive knowledge that one transgressed creates a distinction with regard to sin-offerings, so too, the awareness that one possibly transgressed creates a distinction with regard to provisional guilt-offerings. Therefore if one partook of five olive-sized portions of forbidden fat in one lapse of awareness and then became aware of the possibility that he sinned with regard to one of them and later, became aware of the possibility that he sinned with regard to a second one, and then with regard to the subsequent ones, he is liable for a provisional guilt-offering for each one.

When there is a piece of permitted fat and a piece of forbidden fat and a person ate one of them without knowing which and thus brought a provisional guilt-offering and then partook of the second piece of fat, he must bring a sin-offering. If another person partook of the second piece, that second person must bring a provisional guilt-offering, as stated.

When there is a piece of forbidden fat and a piece of forbidden fat that is notar and a person ate one of them without knowing which one, he must bring a sin-offering to atone for partaking of forbidden fat and a provisional guilt-offering because of the possibility that he partook of notar. If he ate the second piece in a second lapse of awareness, he must bring three sin-offerings. If the piece of notar was worth a p'rutah, he must also bring a definitive guilt-offering because of the misappropriation of consecrated articles.
If he ate one of the two pieces and another person came and ate the second, he should bring a sin-offering and a provisional guilt-offering and the second person should bring a sin-offering and a provisional guilt-offering. Similar laws apply in all analogous situations.
