My husband is 57 and had Italian parents. When he was born they didn't speak English all that well and would have got someone to fill out any paperwork for them. He recently applied for a passport and found that his birth certificate has a female version of his name. While he is ok with his passport having his birth certificate name, we are not sure of the results of not changing his name. Down the track would this cause problems with wills etc that have already been put in place as we have been married for 23 years and this hasn't been picked up before. If he does change his name by deed poll, what else becomes null and void?
