Is the ex entitled to Social Security benefits?

My fiance’s previous marriage lasted 10 years and 3 months, but they were legally separated as of 9 years. Will she be entitled to a portion of his Social Security benefits? If so, how much?

There is no legal separation in NC, so the marriage met the 10 year mark. I cannot say how much she will receive.

Does the ex receiving Social Security benefits reduce the amount that he or I are entitled to?

No.

Ok. Does she have to apply for it, or will it be given to her automatically? Also, will she still receive the benefits if she remarries?

Social security is governed by federal law, not state law. To ensure you get accurate information please visit the Social Security Administration website :http://www.ssa.gov/
