Every principal thing draws the accessory to itself.

Explanation

When the principal thing is granted, transferred, or extinguished, the accessory follows — cite this to argue that a conveyance of the principal estate carries with it all easements, incidents, and appurtenances attached to it.

Where this applies

• A landowner sells a farm, and the court holds that the sale automatically includes the irrigation easement attached to the land because the accessory follows the principal.
• A car is sold at auction, and the buyer argues that the spare tire and jack in the trunk are included because accessories follow the principal thing.
• A company sells its flagship product line, and the court rules that the associated trademarks and trade secrets transfer automatically because they are accessory to the principal asset.
