Hi, thank you for your question. Just a bit more information required to fully assist you:
-Are there court proceedings in place in relation to the financial matter or the children matter, if so what stage has each reached?
Is your daughter a party or intervenor to any of the proceedings?
Thank you and apologies for the delay in responding. Firstly, unfortunately your daughter cannot stop the wife from mentioning her in court paperwork if the husband continues to be in a relationship with her. This is because it is a relevant factor if he is in a long-term and stable relationship, both in relation to the financial matter and the children matter.
I appreciate that this may not be the answer you would have hoped for, but if you found this information helpful please provide a positive rating using the stars at the top of this page. I will not be credited for answering your question without a positive rating. Thank you,
Unless she is a party or an intervenor in the court proceedings she has no obligation to provide this. Her partner will likely be pursued to provide some details of her finances but your daughter has no obligation.
