If you are having problems writing your Law essays then ask your teacher or professor for extra help. A lot of the time, it is all about either finding the right reference books, or fully understanding them. If you are having trouble understanding them, and you are too embarrassed to ask a teacher, then you will need to spend extra time on your studies. You will need to read other books that explain the topic in a different way.
Sometimes when doing Law essays it is very easy to lose your thread. People who are experienced in the law will know which points to focus on and remember when they read a document. For the rest of us, it means having to read and re-read until we are sure we have picked up on every single point. It is not your fault if you keep losing your thread or do not fully understand what is being said in a textbook. Sometimes, even simple ideas can be explained in a way that makes no sense. If you look up the principals you are stuck with, within a different book, it may open the subject up for you. A lot of the time, you are then able to return to the original text and know what it means. It becomes easier to follow.
Many Essays on law deal with very complex issues that are very long winded. This means that as a writer you should go back and keep re-reading your own Law paper to make sure that you are sticking to the same point consistently throughout the text.
Things get even more confusing when you decide to change the focus of your Law focused essays. The more and more you read and research your Papers on law, the more chance that you are going to hit upon a fact that changes the focus of your Legal essays. If it is a smaller point, then you may be able to go back and tweak your current text to agree with the smaller point. If not it may take a full re-write. If you are going back to tweak your text then you have just given yourself one very large proof reading problem. Changing one thing will often have a domino effect when it comes to Law educational essays / law papers. One change near the beginning will mean lots of other changes, which will affect other pieces of the paper. As a rule you are going to have to proofread your text three or four times, just to be sure that you have tied up all of the loose ends. Just to make sure that your essay does not contradict itself at any point.
If you have hit upon a point that means you have to re-write your law essay, then do not be afraid to pillage your older version for good points, quotes and references. Many of the points you make in your first version may still be valid. You can quite easily snip them out of the text and add them into your re-write.
