Pro tem, short for the Latin phrase pro tempore, means for the time being. In legal use, it describes a person temporarily filling a role when the usual officeholder is unavailable.

For example, a Judge may serve pro tem when another judge is unavailable or unable to perform the role.

Pro Tem Explained

The phrase signals temporary service, not unofficial service. A properly designated pro tem official may still carry valid authority within the scope of the assignment for as long as the temporary role lasts.

The Term Pro Tem in Different Legal Contexts

In courts, a judge or attorney may act pro tem when the regular official is absent, incapacitated, or otherwise unable to serve. The phrase can also be used in legislative or organizational settings for temporary officeholders.

Because the role is temporary, the legal source of the appointment matters. Courts and parties may need to confirm that the pro tem designation was properly authorized.

Common Misconceptions About the Meaning of Pro Tem

A common misconception is that pro tem means informal or unofficial. It usually means the appointment is valid but temporary.

Another misconception is that pro tem applies only to judges. The phrase can describe many temporary roles when the regular official is unavailable.
