Is it possible to remove stolen status from stolen items?

Solution 1:

Yes you can. When you sell the stolen goods to a fence, or a merchant if you have the perk, and repurchase it, it will no longer be stolen.

There are some items that retain the stolen flag, such as unique items from the Falmar museum.

Solution 2:

I always give my stolen stuff to my follower then tell him to go home, then recruit him again , and take the item back. For me it is no longer stolen.

Solution 3:

The easiest way to do this:

• Sneak up to some kind of humanoid enemy (for example, a Necromancer).
• Place the 'stolen' items you want to be laundered in the NPC's inventory.
• Kill him/her.
• Collect your laundered items.
