unless there could be problems some where in your app, i wouldn't use a solicitor
a spouse visa 95%+ of people don't have a problem getting their visa
you only need to search on here and you'll find hardly anyone has been refused a spouse visa..
you say shes your g/f i take it your applying for a fiancée visa then ?
and your g/f has 2 children, your need to show she has 'sole responsibility' for them and custody of them,,,
