A more thorough explanation:

Definition: Clamea admittenda in itinere per attornatum is a Latin term that means "claim to be admitted at the eyre by an attorney." It refers to a writ from the king that commands the justices in eyre to allow a person employed in the king's service to make a claim through an attorney because they cannot attend court in person.

One example of clamea admittenda in itinere per attornatum is when a soldier who is serving in the king's army is unable to attend court in person to make a claim. In this case, the soldier can send an attorney to make the claim on their behalf.

Another example is when a government official is on official business and cannot attend court in person. They can send an attorney to make the claim for them.

These examples illustrate how clamea admittenda in itinere per attornatum was used in medieval times to allow people who were unable to attend court in person to make a claim through an attorney.
