Name change not reflected on buddy pass

Can anyone help me out with this question?I am flying non-rev for the first time in quite a while. My mother is a retired Delta employee and bought my pass for me. The problem is that it is in my maiden name, not my married name. She forgot to get it changed with Delta.I asked Mom if this would be a problem with Security and Delta. She said as long as I have a copy of my marriage license with me to show anyone who has a problem with it, I'll be fine.Is this true? We're leaving early Friday morning. I'd appreciate any help I can get!Thanks!
