A mum was left stunned when her ex-husband's new fiancee asked her to legally change her surname.
The woman kept her married name when they divorced because she did not want to have a different surname to her daughter and have the 'hassle' of changing it.
But now, his wife-to-be has asked the mum to consider reverting to her maiden name before they get married.
The mum stressed there's "no conflict" among them and she and her ex share custody of their daughter 50/50, reports Liverpool Echo.
Turning to Mumsnet's popular 'Am I Being Unreasonable' forum, she sought advice in a post titled 'been asked to change my name by ex's partner.
She wrote: "I have been separated from my ExH [ex husband] for four years, divorced for about a year.
"He has been with his new partner for about three-and-a-half years. I'm settled, everyone happy, no conflict and my daughter goes 50/50 between us. All good.
"But I have never changed my name because I don't want to have a different surname to my daughter.
"Also, I just can't be bothered with the hassle to be honest. I see it as my name and my identity really. It would be strange to go back to my maiden name now.
"My ExH is looked to get remarried and he's contacted to say that his partner would be more comfortable if I changed my name back so that she can adopt her married name. My brain can't quite decide if I'm being unreasonable by refusing? I just don't want to change my name".
The mum's post was met with 1,000 responses from fellow Mumsnet users, keen to share their thoughts.
One Mumsnet user said: "Not at all unreasonable. Is there a reason she is so insecure?"
Another said: "Definitely not unreasonable! There’s nothing to stop her being Mrs Ex’s surname."
A third commented: "What a t***!! Tell them both to jog on".
And a fourth said: "No, she's the one being weird about it in my opinion. There must be thousands of people with the same name. Changing yours may also have practical consequences for travel and such in my experience some countries are weird about people travelling with kids who don't have the same surname."
Another suggested: "Of course you're not being unreasonable, it's your surname. If she's not happy to have the same name as you, she can always ask him to take hers."
And another said: "You are not being unreasonable. What a weird and cheeky pair. The name doesn't belong to him."
In follow up comments, the mum said: "It's a very common name too. Think 'Davies' kind of thing. To be honest I was so taken aback that I don't actually know how to respond.
"They seem to think it's a very reasonable request. I feel like I'm losing my marbles trying to digest this one."
She later added: "Have now responded with 'I'm assuming that's a joke?' Let's see where that gets me."
The mum the elaborated on the situation in a further follow up comment after receiving their reply.
According to the mum, it read: "It's just something we feel should be between a married couple. Otherwise all three of us will have the same surname. Have a think about it and let me know if you need help covering the costs of changing docs etc."
The mum said: "I went back and said the following 'thanks for the offer but i won't be changing it on your say so. Perhaps in the future when DD is older I will decide I'd like to change it. For now I will be keeping it. I do wish you both the very best though.'
"I won't be engaging with any more of it now even if I do get a reply. I think that's fair?"
