Domestic partner med benefits tax deductible?

At my former job, I was actually able to enroll my opposite domestic partner whom I've been living with for over a years on my medical plan and her benefits came out after tax? The living status was notarized. Would these be tax deductible? She has not made more than $3000 this year, and I highly doubt will. I paid out quite a bit on her, so if they are indeed deductible, I would like to take advantage of it!
