A more thorough explanation:

SURSUM REDDERE

Sursum reddere is a Latin term used in conveyancing, which means to surrender or render up property rights.

• John decided to sursum reddere his ownership rights of the property to his brother.
• The landlord asked the tenant to sursum reddere the keys to the apartment after the lease ended.

The examples illustrate how sursum reddere is used in the context of transferring property rights. In the first example, John is giving up his ownership rights to the property, while in the second example, the tenant is surrendering their right to access the apartment by returning the keys to the landlord.
