Applying Visitor Visa for parent-in-laws

[naresh.vit]

Hi,

I am planning to apply visitor visa for my parent-in-laws. My parent-in-law has a change of name and her passport was with new name.
In my wifes passport her mother name was with old name. I would like to know will this be an issue while applying for visitor visa?

If this is the case do I need to submit any extra documents when applying for a VISA? or is it better to change the Mother's name in my wife's passport?
