A more thorough explanation:

Jus Curialitatis

Jus curialitatis is a Latin term used in legal history that refers to the right of curtesy.

The right of curtesy is a legal concept that grants a husband certain rights to his deceased wife's property. This right is based on the idea that the husband has contributed to the marriage by supporting his wife and family, and therefore deserves some compensation after her death.

For example, if a husband and wife own a house together and the wife dies, the husband may have the right of curtesy to the property. This means that he can continue to live in the house and use it as his own, even though he does not technically own it. However, this right is usually limited to the husband's lifetime and does not pass on to his heirs.

Another example of jus curialitatis is the right of a husband to receive a portion of his deceased wife's personal property, such as jewelry or clothing. This right is based on the same principle of compensation for the husband's contributions to the marriage.

These examples illustrate how jus curialitatis was used to protect the rights of husbands in marriages where they had made significant contributions to the household and family.
