10 year Ban since 2009

I am a British citizen living in the UK but have a fiancee living outside the country. She was banned in 2009 when she applied to come to study in the UK. Her agent included a fake bank statement which led to the 10 year ban. We are planning to marry sometime in 2019 which makes 10 years after the ban, can you please advice us if she might have difficulty gaining entrance to the UK or will this be a straight forward application as long as she mentions that she was banned and refused entry 10 years ago and now all current documents are genuine.
