The Official Death Note Rulebook
This is the official Death Note rulebook. I did not make any of these rules. If you believe any of these are stupid, take that up with the Death Note author, not me. I enjoy that there are rules because they will force me to be creative, rather than having him do something simple like writing Hulk to kill everyone.
The numbers are not right, I'm not sure if the website is just weird or if in the manga, they just don't give you every single rule. So, ignore the blanks I guess. If someone knows the blanks, if the blanks aren't intentional, let me know.

1.1 Entering Names
The human whose name is written in this note shall die. This note will not take effect unless the writer has the subject's face in mind when writing his/her name. This is to prevent people who share the same name from being affected.

1.1 Entering Names
When the same name is written in two or more Death Notes, the Note which was used first will take effect, regardless of the time of death.
4
I. How to Use It
1.1 Entering Names
If the same name is written in two or more Death Notes within 0.06 seconds, the entry is regarded as simultaneous; the Death Notes will not take effect and the individual will not die.
5

1.1 Entering Names
If a Death Note owner accidentally misspells a person's name four times, that person will be free from being killed by the Death Note. However, if the Death Note owner intentionally misspells the name four times, the owner will die.
The Japanese version also includes: The person whose name was misspelled four times on purpose will not be free of death by a Death Note.

I. How to Use It
1.1 Entering Names
The Death Note will not take effect if a victim's name is written on several different pages. However, the front and back of a page are considered to be one page. For example, the Death Note will still take effect if the victim's last name is written on the front page and first name on the back.

1.2 Entering the Causes and Conditions of Death
If the cause of death is written within 40 seconds of the subject's name, it will happen.
11

1.2 Entering the Causes and Conditions of Death
If the cause of death is not specified, the subject will die of a heart attack.
12

1.2 Entering the Causes and Conditions of Death
After writing the cause of death, the details of death should be entered within the next six minutes and 40 seconds.
13
I. How to Use It
1.2 Entering the Causes and Conditions of Death
If the time of death is specified within 40 seconds after writing the cause of death as a heart attack, the time of death can be manipulated and can go into effect within 40 seconds after writing the name.
14
I. How to Use It
1.2 Entering the Causes and Conditions of Death
The conditions of death will not be realized unless they are physically possible for that human or could be reasonably assumed to be carried out by that human.
15
I. How to Use It
1.2 Entering the Causes and Conditions of Death
Since the limitations applying to the conditions of a death are unknown to the Shinigami, Death Note owners must find out on their own.
16
I. How to Use It
1.2 Entering the Causes and Conditions of Death
You may write the cause and/or details of death prior to filling in the name of the individual. Be sure to insert the name in front of the cause of death. You have about 19 days (according to the human calendar) to fill in a name.
17
I. How to Use It
1.2 Entering the Causes and Conditions of Death
Suicide is a universally valid cause of death as all humans are thought to possess the potential to commit suicide. It is, therefore, something that may be reasonably assumed of an individual.
18
I. How to Use It
1.2 Entering the Causes and Conditions of Death
Whether the cause of the individual's death is either suicide or an accident, if it would lead to the death of more than the intended victim, the person will simply die of a heart attack. This is to ensure that other lives are not impacted.
19
I. How to Use It
1.2 Entering the Causes and Conditions of Death
After an individual's name, time of death, and conditions of death are entered in the notebook, the time and conditions of death may be altered as many times as desired as long as they are changed within six minutes and 40 seconds from the time they are filled in. But, of course, this is only possible before the victim dies.
20
I. How to Use It
1.2 Entering the Causes and Conditions of Death
If you write "dies of accident" for the cause of death, the victim will die from a natural accident six minutes and 40 seconds after the time of entry.
21
I. How to Use It
1.2 Entering the Causes and Conditions of Death
Even if only one name is written in the Death Note, if the victim's death causes other humans that are not written in it to die, the cause of death will default to a heart attack.
22
I. How to Use It
1.2 Entering the Causes and Conditions of Death
If you write "dies from disease" and specify which disease and the time of death, there must be a sufficient amount of time for the disease to progress. If the set time is too tight, the victim will die of a heart attack six minutes and 40 seconds after the entry in the Death Note.
23
I. How to Use It
1.2 Entering the Causes and Conditions of Death
If you write, "dies from disease" as the cause of death but specify only a time of death and not the actual disease, the victim will die from a plausible disease.
24
I. How to Use It
1.2 Entering the Causes and Conditions of Death
The Death Note can only operate within a 23-day window (in the human calendar). This is called the 23-Day rule.
25
I. How to Use It
1.2 Entering the Causes and Conditions of Death
If you write "dies from disease" and specify which disease but not a time of death, if the progression of the disease takes more than 24 days, the 23-Day rules will not take effect and the human will die at an appropriate time depending on the disease. However, rewriting the cause and/or details of death must be done within six minutes and 40 seconds: you cannot change the victim's time of death, however soon it may be.
26
I. How to Use It
1.2 Entering the Causes and Conditions of Death
In order for the Death Note to take effect the victim's name must be written on one page; however, the cause and conditions of death may be entered on other pages. This will work as long as the person who writes in the Death Note keeps the specific victim's name in mind when writing the cause and conditions of death.
27
I. How to Use It
1.2 Entering the Causes and Conditions of Death
If the cause and conditions of death are written in before the victim's name is, multiple names can be written as long as they are entered within 40 seconds and the cause and conditions of death are not impossible. In the event that the cause of death is possible but the conditions are not, only the cause of death will take effect for that victim. If both the cause and the conditions are impossible, that victim will die of a heart attack.
28
I. How to Use It
1.2 Entering the Causes and Conditions of Death
When you write multiple names in the Death Note and then write down one cause of death within 40 seconds of writing the first victim's name, the cause will take effect for all the written names. Also, after writing the cause of death, even if the conditions of death are written within six minutes and 40 seconds in the human world, the conditions will apply only to the victims for whom they are possible. Those for whom the conditions are not possible will simply die from the specified cause.
29
I. How to Use It
1.2 Entering the Causes and Conditions of Death
A human death caused by the Death Note can indirectly lengthen another human's original life span in the human world even without the owner's specific intention to do so.
30
I. How to Use It
1.2 Entering the Causes and Conditions of Death
Once the victim's name, cause of death, and conditions of death have been written down in the Death Note, the death will take place even if that Death Note, or the part of the note used, is destroyed before the stated time of death.
31
I. How to Use It
1.2 Entering the Causes and Conditions of Death
If the victim's name has been entered and the Death Note is destroyed while the cause of death is being written, the victim will be killed by a heart attack 40 seconds after the name was entered. If the victim's name and cause of death have already been written, then the victim will be killed within six minutes and 40 seconds via the stated cause of death if it is possible within that period of time. Otherwise, the victim will die by heart attack.
32
I. How to Use It
1.3 Alterations
If you wish to change anything written in the Death Note within six minutes and 40 seconds after you wrote it, you must first rule out the characters you want to erase with two straight lines. The time and conditions of death can be changed, but once the victim's name has been written, that individual's death can never be averted.
33
I. How to Use It
1.3 Alterations
It is useless to try to erase names written in the Death Note with erasers or to white them out.
35
I. How to Use It
1.3 Alterations
Even if a new victim's name, cause of death, or conditions of death are written on top of the original victim's name, cause of death, or conditions of death, there will be no effect on the original victim's death. The same thing will also apply to erasing what was written with a pencil, or whiting out what was written with a pen.

1.4 Limitations
The Death Note will not affect those less than 780 days old.

1.5 Other Things to Consider
The human who uses this note can go neither to Heaven nor to Hell.

1.5 Other Things to Consider
One page taken from the Death Note, or even a fragment of the page, possesses the full power of the note.

1.5 Other Things to Consider
Any writing instrument or medium (cosmetics, blood, etc.) may be used, as long as it can write directly onto the note and create legible text.

The pages of the Death Note will never run out.

1.5 Other Things to Consider
Some limited number of Death Notes have white or red front covers, but this makes no difference in their effectiveness as compared with the black Death Notes.
46
II. Ownership
---
This note shall become the property of the human world once it touches ground in the human world.
47
II. Ownership
---
The owner of a Death Note can recognize the image and voice of the original owner - a Shinigami, for example.
48
II. Ownership
---
The human who touches the Death Note can recognize the image and voice of its Shinigami owner, even if the human is not the owner of the note.
49
II. Ownership
---
Whenever a Shinigami in the human world dies and leaves behind its Death Note, the note's finder automatically becomes the owner. However, in this case, only a human who can see and hear that Shinigami is able to see and touch the Death Note. It is very unlikely, but if by any chance another Shinigami picks up the Death Note, that Shinigami becomes the owner.
50
II. Ownership
2.2 Situations Surrounding Ownership
If you lose the Death Note or have it stolen, you will lose its ownership unless you can retrieve it within 490 days.
51
II. Ownership
2.2 Situations Surrounding Ownership
When the owner of the Death Note dies while the note is on loan, its ownership will be transferred to the person who is holding it at that time. If the Death Note is stolen and the owner is killed by the thief, its ownership will automatically be transferred to the thief.
52
II. Ownership
2.2 Situations Surrounding Ownership
The individuals who lose ownership of a Death Note will also lose their memories of it. However, this does not mean that they will lose all memories from the period of ownership: they will only lose the memories involving the Death Note.
53
II. Ownership
2.2 Situations Surrounding Ownership
When an individual with ownership of more than two Death Notes loses possession of one of them, he will no longer be able to recognize or hear that Death Note's Shinigami anymore. The Shinigami will leave, but all the memories involving the Death Note will remain to the owner as long as he maintains ownership of at least one other Death Note.
54
II. Ownership
2.2 Situations Surrounding Ownership
If a person loses possession of a Death Note he will not recognize its Shinigami by sight or voice anymore. However, if the owner lets someone else touch that Death Note, from that time on that person will continue to recognize the Shinigami's appearance and voice until he or she actually becomes the owner of the Death Note and subsequently loses possession of it.
55
II. Ownership
2.2 Situations Surrounding Ownership
When regaining ownership of a Death Note, the memories associated with it will also return. In cases where the owner was involved with other Death Notes as well, memories of all the Death Notes involved will return. The memories will return just by touching the Death Note, even without obtaining ownership of it.
56
II. Ownership
2.2 Situations Surrounding Ownership
Memories related to a Death Note are lost when its ownership is lost. But they may be regained by either obtaining ownership once again or by touching the Death Note. This can be done up to six times per Death Note. Any times more than that, the person's memory of the Death Note will not return and they will have to use it without any previous memory of it.
57
II. Ownership
2.2 Situations Surrounding Ownership
Even if you do not actually possess the Death Note, you may still use it to full effect.
58
II. Ownership
2.2 Situations Surrounding Ownership
You may lend the Death Note to another person while maintaining its ownership. The borrower may lend it to yet another person as well.
59
II. Ownership
2.2 Situations Surrounding Ownership
The person who borrows the Death Note will not be followed by a Shinigami. The Shinigami always remains with the owner of the Death Note. Also, the borrower cannot trade for the Shinigami Eyes.
60
II. Ownership
2.2 Situations Surrounding Ownership
Only by touching each other's Death Notes can owners recognize the appearance or voice of each other's Shinigami.
61
II. Ownership
2.2 Situations Surrounding Ownership
Losing memory of the Death Note by passing the ownership to another or by abandoning ownership will only occur when someone is actually killed using that Death Note. You will not lose memory of the Death Note if, for example, you merely owned it and did not write down anyone's name. In this case, you will not be able to hear or see the Shinigami anymore. You will also lose the power of the Shinigami Eyes if you made the trade.
62
II. Ownership
2.3 Multiple Notebooks
Someone possessing more than one Death Note may write down a victim's name in one of the Death Notes and the cause of death in the other, and the death will still occur. The order of writing, however, is unimportant: if you write down the cause of death in one Death Note and afterward write the name in the other, the death will occur. This can be accomplished by two Death Note owners working together. In this case, it's necessary that the two touch each other's Death Notes.
63
II. Ownership
2.3 Multiple Notebooks
Only six Death Notes are allowed to exist at a time in the human world. Of course, the Death Notes that the Shinigami own do not count. This means only six Shinigami that have passed on their Death Notes to humans can be in the human world at once.
64
II. Ownership
2.3 Multiple Notebooks
One Shinigami is allowed to pass on Death Notes to only three humans at a time. However, it is possible for a single Shinigami to hand out up to six Death Notes - by handing three humans two Death Notes each, for example. In other words, one human could potentially own all six Death Notes.
65
II. Ownership
2.3 Multiple Notebooks
If a seventh Death Note is given to a human when six already exist in the human world, nothing will happen when it is used.
66
II. Ownership
2.3 Multiple Notebooks
In the event that there are more than six Death Notes in the human world, only the first six Death Notes that have been delivered to humans will have effect. The seventh Death Note will not become active until one of the other six Death Notes is destroyed or a Shinigami takes one of them back to the Shinigami realm.
67
III. The Shinigami Eyes
---
A human who becomes the owner of a Death Note can, in exchange for half of his or her remaining life, acquire the power of the Shinigami Eyes, which will enable him or her to see a human's name and remaining life span when looking at them.
68
III. The Shinigami Eyes
---
If you have traded for the Shinigami Eyes, you will lose that power as well as the memories of the Death Note once you lose ownership of the note. Moreover, the half of your life you traded away will not be restored.
69
III. The Shinigami Eyes
---
An individual with Shinigami Eyes can see the name and lifespan of another human by looking at that person's face. By gaining ownership of a Death Note, an individual not only gains the ability to kill but also cannot be killed by a Death Note. From this point on, a person with a Death Note cannot see the life span of other Death Note owners, including him- or herself.
70
III. The Shinigami Eyes
---
In order to see the names and life spans of humans using the power of the Shinigami Eyes, the owner must be able to see more than half of that person's face. When looking from top to bottom, he must be able to see at least from the head to the nose. If he looks at only the eyes and under, he will not be able to see the person's name and lifespan. Also, even though some parts of the face - for example the eyes, nose or mouth - are hidden, if he can basically see the whole face he will be able to see the person's name and lifespan.
71
III. The Shinigami Eyes
---
It is still not clear how much exposure is needed to see a name and life span (more research needs to be done). If the above conditions are met, names and life spans can be seen using photos and digital images, no matter how old they are. But this is sometimes affected by the resolution and size of the image. Also, names and life spans cannot be seen using drawings, however realistic they may be.
72
III. The Shinigami Eyes
---
Those with Shinigami Eyes will have eyesight of over 3.6 in the human measurement, regardless of their original eyesight.
73
III. The Shinigami Eyes
---
If you have traded for the Shinigami Eyes, you will see a person's primary life span in the human world.
74
III. The Shinigami Eyes
---
The names you will see with the Shinigami Eyes are the names needed to kill that person. You will be able to see a name even if it isn't officially registered anywhere.
75
III. The Shinigami Eyes
---
Humans who have traded for Shinigami Eyes cannot see the names or life spans of humans who have already passed away (by looking at photos of them, for example).
76
III. The Shinigami Eyes
---
The use of the Death Note in the human world sometimes affects other humans' lives or shortens their original life spans, even if their names are not actually written in the notebook itself. In these cases, no matter the cause, the Shinigami sees only the original lifespan and not the shortened lifespan.
77
III. The Shinigami Eyes
---
No matter what medical or scientific method is employed, it is impossible for humans to distinguish whether or not a human has Shinigami Eyes. Even Shinigami cannot distinguish this fact, except for the very Shinigami that traded his or her eye power with that human.

IV The Shinigami Rules
4.1 Relationship with the Owner
The human owner of a Death Note is possessed by its original Shinigami owner until he or she dies.

4.1 Relationship with the Owner
If a human uses a Death Note, its Shinigami owner must appear in front of the human within 39 days after he or she uses the note.
80
IV The Shinigami Rules
4.1 Relationship with the Owner
The original Shinigami owners of Death Notes don't, in principle, do anything to help or prevent the deaths brought about by the notes.
81
IV The Shinigami Rules
4.1 Relationship with the Owner
A Shinigami has no obligation to completely explain how to use the note or the rules that apply to the human who owns it.
82
IV The Shinigami Rules
4.1 Relationship with the Owner
The Shinigami must not tell humans the names or life spans of individuals he sees. This is to avoid confusion in the human world.
83
IV The Shinigami Rules
4.1 Relationship with the Owner
A Shinigami bringing a Death Note into the human world must make sure that a human uses it. Although it is unlikely that a Shinigami who has possessed a human would die, if it does happen, the Death Note brought into the human world will not lose its power.
84
IV The Shinigami Rules
4.1 Relationship with the Owner
Shinigami must not stay in the human world without a particular reason. Acceptable reasons to stay in the human world are as follows:
I. When the Shinigami's Death Note is handed to a human.
II. Finding a human to take possession of a Death Note should be done from the Shinigami realm, but if it is within 82 hours this may also be done in the human world.
III. When a Shinigami stalks an individual with an intention to kill them, as long as it is within 82 hours of possessing them the Shinigami may stay in the human world.
88
IV The Shinigami Rules
4.1 Relationship with the Owner
The Shinigami must not hand the Death Note directly to a child under six years of age (based on the human calendar). But Death Notes that have been dropped into the human world, and are part of the human world, can be used upon humans of almost any age with the same effect.
89
IV The Shinigami Rules
4.1 Relationship with the Owner
The owner of a Death Note cannot be killed by a Shinigami who is in the Shinigami realm. Also, a Shinigami who comes to the human world with the objective of killing the owner of a Death Note will not be able to do so. Only a Shinigami that has passed on its Death Note to a human is able to kill the owner of the Death Note.
90
IV The Shinigami Rules
4.1 Relationship with the Owner
If a Death Note is owned in the human world against a Shinigami's will, that Shinigami is permitted to stay in the human world in order to retrieve it. In that case, if there are other Death Notes in the human world, the Shinigami are not allowed to reveal to the humans the Death Note owner's identity or its location.
91
IV The Shinigami Rules
4.1 Relationship with the Owner
If a Shinigami's Death Note is taken away for whatever reason, it can only be retrieved from the Shinigami who possesses it at the time. If there is no Shinigami, but a human, the only way the Shinigami can get it back is to first touch the Death Note and become the one who haunts that particular human. Then they have to wait until that person dies to take it away. And they have to do it before any other human touches it.
92
IV The Shinigami Rules
4.1 Relationship with the Owner
After a Shinigami brings a Death Note to the human world and gives its ownership to a human, the Shinigami has the right to kill the human using its own Death Note for any reason, such as disliking the owner.
93
IV The Shinigami Rules
4.1 Relationship with the Owner
The following are cases in which a Shinigami that has brought the Death Note into the human world is allowed to return to the Shinigami realm:
I. When the Shinigami has seen the end of the first owner of the Death Note brought into the human world and has written that human's name into his or her own Death Note.
II. When the Death Note is destroyed and cannot be used by humans anymore.
III. If nobody claims ownership of the Death Note, it is unnecessary to possess anyone.
IV. If, for any reason, the Shinigami possessing the Death Note is replaced by another Shinigami.
V. When a Shinigami loses track of the Death Note that he or she possesses, or cannot identify which human owns the Death Note, or cannot locate where the owner is, and therefore needs to find such information using the observation holes in the Shinigami realm.
VI. Even in cases II, III, and IV, Shinigami are obliged to confirm the death of the first owner and write down that human's name in his or her Death Note even when he or she is in the Shinigami realm.
100
IV The Shinigami Rules
4.1 Relationship with the Owner
In the Shinigami realm there are a few copies of what humans might call a "user handbook" for the Death Notes in the human world. Although Shinigami may not give the handbook to humans, it is perfectly okay for them to teach humans about its contents, no matter what that may be.
101
IV The Shinigami Rules
4.2 Using the Death Note
A Shinigami can extend its life by writing human names in a Death Note, but a human cannot. A person can only shorten his or her life by using the note.
102
IV The Shinigami Rules
4.2 Using the Death Note
Even the original Shinigami owners of Death Notes do not know much about them.
103
IV The Shinigami Rules
4.2 Using the Death Note
Shinigami must own at least one personal Death Note, which must never be lent to or written on by a human.
104
IV The Shinigami Rules
4.2 Using the Death Note
Shinigami may exchange and write in each others' Death Notes.
105
IV The Shinigami Rules
4.2 Using the Death Note
If a Shinigami decides to use a Death Note to end the life of the killer of an individual it favors, that individual's life will be extended but the Shinigami will die. The Shinigami will disappear but the Death Note will remain. The ownership of this Death Note is usually carried over to the next Shinigami that touches it, but it is common sense that it be returned to the Shinigami King.
106
IV The Shinigami Rules
4.2 Using the Death Note
By manipulating the death of a human who has influence over another human's life, that human's original life span can sometimes be lengthened. If a Shinigami intentionally does this that Shinigami will die, but even if a human does the same, the human will not die.
107
IV The Shinigami Rules
4.3 Shinigami Life
A Shinigami cannot be killed even if stabbed or shot. However, there are ways to kill them, which are not generally known even to the Shinigami themselves.
108
IV The Shinigami Rules
4.3 Shinigami Life
There are male and female Shinigami, but it is neither permitted nor possible for them to have sexual relations with humans. They also cannot have sex with each other.
109
IV The Shinigami Rules
4.3 Shinigami Life
As long as a Shinigami has at least once seen a human and knows his or her name and life span, the Shinigami is capable of finding that human by looking down from an observation hole in their realm.
110
IV The Shinigami Rules
4.3 Shinigami Life
The Shinigami realm has laws that govern it. If a Shinigami should break a law, there are nine levels of punishment, which the severity starting at Level Eight and going up to Level One, plus an Extreme Level. At severity levels above Three, the Shinigami will be punished and killed. Killing a human without using the Death Note merits punishment at the Extreme Level.
111
IV The Shinigami Rules
4.3 Shinigami Life
Shinigami will not die from lack of sleep. They do not need sleep, so to them it is merely laziness. Shinigami in the human world shouldn't act lazy merely because they are required to possess a human.
