on the wifes visa and passport states her maiden name but now shes a married lady here and we change her name to my surname will that play havoc with the ILR visa??

this is something that has been niggling me- i would like her to take my name legally-= at present we sort of hyphenate it but not for any official paperwork where we still use her maiden name ie DWP for NI number and regustered at the docs etc

and suggestions advice on this one?
