“My wife is “dragging her feet” on the completion of a Marriage Separation Agreement. Am I obligated to pay the mortgage, utilities, and other bills without an agreement in place?”

Whether or not you are obligated, it’s prudent to do so, however you should have your lawyer a) file a motion to have the court put a timeline in place for the completion of the MSA, and b) make sure that you are reimbursed for expenses incurred during the separation.
