There are many ways to analyze handwriting. Spacing is a big thing, the left margin can be even, jagged, slanting to the left, and slanting to the right. You can also look at how much space there is between the capital letters and the lower case letters. Another big thing is letter slant. Your letters can slant to the right or to the left. This is a big thing is identifying the person who wrote it.

There are ways to tell if someone has tampered with a document. You can put the paper under and light and it would show if there is anything that was added later. You could also tell by how thick the paper is. They could have scratched off the ink and wrote something different. Things that you should look for would be like on a check. They would try and change the amount so that they would get more money. This is just one reason why they would change a document.
