A more thorough explanation:

Definition: In Roman law, a litura refers to a blot or erasure in a will or other legal document.

Example: If a person writes a will and then changes their mind about a certain provision, they may attempt to erase or blot out that provision. However, if the will is later contested in court, the presence of a litura may raise questions about the validity of the document.

Explanation: The example illustrates how a litura can impact the legal validity of a document. If a will contains a litura, it may be unclear whether the person making the will intended to revoke or modify the provision in question. This can lead to disputes and legal challenges, as parties may argue over the meaning and effect of the litura.
