"length" of marriage

Thank you for this terrific resource.

I know that the length of marriage can be a factor in an alimony award. Does the judge look at the length of marriage up until the time of separation, or up to the date of divorce? This is pertinent in my case due to a fairly long period between physical separation and the beginning of legal activities.

thanks again

It is the length of coveture, ie the time period from the date of marriage to the date of separation.
