This is an interesting discussion. It hasn't come up in my game as yet but since one of the characters has combat expertise it could well, so its good to make a ruling on this now rather than on the spot.
My take is a little different than the the rest of the thread however. I've had a good think about it and have decided in favour of the defender. I will explain how and my reasoning behind it.
Combat Expertise: Rather than impose a penalty for the the opposed roll for the character using combat expertise I will allow them to add the defence amount to their opposed roll.
This bonus will also apply to Parry or Dodge as an added bonus, fighting defensively, full defense and even intricate swordplay(basically any thing that adds to defence).
Reasoning: If a character is defensively minded and sacraficing their attack, or have extra defensive experience then their is no reason why this shouldn't apply to them when being sundered/disarmed. If my enemy was trying to sunder an item I am wearing all the above defences would hinder him so why not when he is attcking my shield or weapon?
I dont subscribe to the idea that because I have a penalty on my attack roll I am making a weak attack(Power attack?) as my attack does the same amount of damage as normal. I also don't believe weapons break as easily as they are made out. Swords are designed to parry other swords and shields aren't easily cloven in two. Weapon breakage in d20 is a fantasy mechanic. Weapon breackage in the Conan stories is artistic licence and dramatic. Knights didn't carry half a dozens swords with them to battle because they are going to break.
If you do apply the penalty to the opposed roll your going to have players who might want to fight defensively all readying an action. I ready against being attacked. So if I am attacked I can choose to expertise/ fight defensively but if he attacks my weapon I am fighting normaly. Silly
Just my opinion.
