Hi terrie first of all congratulations on your marriage and best wishes.I was on the same position before but what I did was I ammended my passport first before I applied for a spouse visa.It will not take you longer minimum of 3 days and maximum of 0ne week you just have to present your old passport (its alright if its still valid) and your MC.I think its better doing it this way to lessen the complication afterwards when you`re already in u.k Hope that hepls.Goodluck!
