A more thorough explanation:

Transit terra cum onere

When land is sold or transferred, any burdens or responsibilities associated with the land also transfer to the new owner.

• If a piece of land has a mortgage on it, and the land is sold to a new owner, the new owner is responsible for paying off the mortgage.
• If a piece of land has a lien on it, and the land is sold to a new owner, the new owner is responsible for satisfying the lien.

These examples illustrate how the definition of transit terra cum onere works. When land is transferred, any burdens or responsibilities associated with the land also transfer to the new owner. This means that the new owner is responsible for any debts or obligations that were attached to the land before they acquired it.
