  </blockquote>
  <p>The <a href="https://handbook.fide.com/chapter/E012018" rel="noreferrer">FIDE Laws of Chess</a> say this about the ownership of the scoresheet:</p>
  <blockquote>
  <p>8.3  The scoresheets are the property of the organiser of the competition.</p>
  </blockquote>
  <p>and they say this about sharing the scoresheet:</p>
  <blockquote>
  <p>8.5.2    If only one player has not kept score under Article 8.4, he must, as soon as either flag has fallen, update his scoresheet completely before moving a piece on the chessboard. Provided it is that player’s move, he may use his opponent’s scoresheet, but must return it before making a move.</p>
  </blockquote>
  <p>So, you are not allowing your opponent to take a photo of <em>your</em> scoresheet, you are allowing your opponent to take a photo of the <em>organiser's</em> scoresheet for your game and there are certain events which can happen during the game which <em>require</em> you to share the scoresheet you are keeping.</p>
  <p>Although the rules are silent on what happens after the game regarding sharing the scoresheet it would appear churlish to deny your opponent a photo. Arguably your opponent needs the permission of the organiser, the owner of the scoresheet, not you, in order to make a copy.</p>

  You did the right thing! I would definitely allow my opponent to take a picture of the scoresheet. There is no need to be sour, as it is very unlikely you had or will have any disadvantages from **his** behaviour.
  It was your choice to spend time recording the moves and one single game will not help him in a meaningful way to prepare against you next time, even if he didn't have ChessBase. Even if it did, you would still need to be matched.
  
  Of course, it would not have been sportsmanlike if he had already started to record the moves and stopped doing that after noticing you keep recording the moves **only in the hopes of getting them from you later**. In this case, rather than alleging that so. has such dishonest motives, grant him the benefit of the doubt and show magnanimity.
  In the case described, I would assume that he would not have recorded the moves anyway and only asked for the sheet because it was nice to have.
  
  Try to separate your emotions about the game itself from such questions.
  I find it hard to believe that you would have such thoughts if you had taken the full point effortlessly.
  If that player does not already have a reputation for taking advantage of others, I will second username_6' opinion that refusing the scoresheet would appear rather petty.

But the document you wrote during the game is not a score sheet as understood by the rules, these are just your personal notes that happen to have a form that is very similar to a score sheet.

  You dont have any obligation. If I was playing a friend I would give it to them but if I thought he was doing it to gain an advantage, which he is by forcing you to use your time, I wouldn't.
  
  He is choosing to not record the game. If you give it to him its a favor.
  
  Besides, how does someone not remember the game they just played? Thats just laziness. Back in the day, before smartphones and before I had internet, I would go down to the local library and play online for 4-5 hours then come home and transcribe the 10-15 most interesting games. How can someone not remember ONE game they just played?
