# Subdividing body in three parts and drawing line to show division

I would like to have a page display like this one :

[n] being the page number. I won't need to write anything in the right and bottom part. (I just need those spaces to put handwritten comments). Chapter page and the table of content should have a classic display.

For now, I have this code :

\documentclass[12pt]{report}

\usepackage[left=1in, right=1in, bottom=1in, top=1in]{geometry}
\usepackage{fancyhdr}

\pagestyle{fancy}
\renewcommand{\footrulewidth}{1pt}
\fancyfoot[R]{\thepage}
\fancyfoot[C]{}

\def\footrule{{\if@fancyplain\let\footrulewidth\plainfootrulewidth\fi
\vskip-\footruleskip\vskip-\footrulewidth
\leavevmode\rlap{\hspace*{-2in}\rule{2\paperwidth}{\footrulewidth}}
\vskip\footruleskip}}

\begin{document}

\newgeometry{left=.5in, right=1.5in, bottom=2.5in, top=.5in}

\hspace{\fill}\rule{\footrulewidth}{575pt}

\end{document}


And it's output this :

Top-right corner is offset and the page number is also at the wrong place. I think I need to rework completely the code to overcome those difficulties, but I have no idea how to do it.

Since you need to write only by hand in the right and bottom part, I thought your layout could be created easily with tikz, as a page background.

I also added these two lines of code from a Mico's answer to make the chapter first page like the others:

\usepackage{etoolbox}
\patchcmd{\chapter}{\thispagestyle{plain}}{\thispagestyle{fancy}}{}{}


Here is my MWE:

\documentclass[12pt]{report}
\usepackage[left=.5in, right=2in, bottom=2.5in, top=.5in, marginparwidth=0pt]{geometry}
%\usepackage{showframe}
\usepackage{eso-pic}
\usepackage{tikz}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyfoot[R]{}
\fancyfoot[C]{}
\renewcommand{\footrulewidth}{0pt}
% the following two lines of code are from: https://tex.stackexchange.com/a/117334/101651
\usepackage{etoolbox}
\patchcmd{\chapter}{\thispagestyle{plain}}{\thispagestyle{fancy}}{}{}

\usepackage{mwe}% for testing purpose only

\begin{document}
\AtPageLowerLeft{%
\begin{tikzpicture}[overlay,remember picture]
% horizontal line
\draw[line width=1pt] (0,.214\paperheight) -- (\paperwidth,.214\paperheight);
% vertical line
\draw[line width=1pt] (.8\paperwidth,\paperheight) -- (.8\paperwidth,.214\paperheight);
% page number at the very bottom
\node[text width=4em, align=right] at (.93\paperwidth,.03\paperheight) {\thepage};
% "Key Words:" at the very top
\node at (.88\paperwidth,.97\paperheight) {Keys Words:};
\end{tikzpicture}}}
% The following lines are for testing purpose only
\tableofcontents
\chapter{This is for testing purpose only}
\section{Some text with a footnote}
\blindtext\footnote{A test footnote.}
\blindtext[3]
\section{Some text without footnotes}
\blindtext
\chapter{Just to show the page numbering}
\blindtext[10]
\end{document}


And here are some sample pages:
