Selling my rental house have a tax question

[Ian Russell]

I am selling my house awhich was my primary residence.  I moved out last year and began renting it out.   I understand that I can take up to 250,000 tax exemption if I am single or a 500,000 tax exemption if I am married.  I got married last November but I am the only one on the title of the house.  Do I need to put my wife on title to get the 500,000 tax exemption or since we are now married we qualify?  thanks
