How do I file a quiet title motion in Utah with out an attorney

We need more details about why you are filing a quiet title.

Unless the dispute is connected with a pending lawsuit, you would first have to file as suit, before you could file a motion.

A motion is to a lawsuit as a battle is to a war.

To find out how, exactly to proceed, I suggest that you read up on civil procedure. Search for the Utah rules of civil procedure, &/or the statutes governing civil procedure (some states put procedure in rules and others put it in their statutes.)
