Also ask on Bogleheads as suggested above.
Using your link....
"If you are eligible for both your own retirement benefit and for benefits as a spouse, we will always pay you benefits based on your record first. If your benefit as a spouse is higher than your retirement benefit, you will receive a combination of benefits equaling the higher spouse's benefits."
That is why I asked if she had worked... she might not be able to get spousal benefits...
From reading the requirements, there is nothing in there about lenght of marriage.... so like others I would assume zero... if they don't say, it is not a requirement...
