Newly Weds House Sale Capital Gains Exemption

[George Post]

Howdy my Tax Pro's!

Let's say there is a couple. The guy has owned a house for 8 years, she's been living with him for over two years, then they get married this Winter. They are looking to sell that house and move this Spring. Would they then qualify for the full $500k exemption? Does she need to get added to Title prior to sale? Do they need to be married for over years for the full exemption?

TIA!
