A more thorough explanation:

cum suo onere

cum suo onere means "with its burden" in Latin. In history, it was used to refer to the land encumbrances of a vassal that the superior was obligated to accept upon the vassal's resignation.

• When the vassal resigned, the lord had to accept the land cum suo onere, which meant that the lord had to take on any debts or obligations that came with the land.
• After inheriting the property, the new owner had to deal with the property cum suo onere, which included a mortgage and unpaid taxes.

These examples illustrate how cum suo onere was used to describe the transfer of land with its existing burdens. The phrase ensured that the new owner or superior was aware of any debts or obligations that came with the land and was obligated to accept them.
