I'm looking for some solid mumsnet advice, please :)
My husband has children from a previous marriage. The agreement during the divorce 10 ish years ago was for 50:50 custody (verbally agreed, no court involved). However, over the years, one of the children has wanted to spend more time at her mums. This has led to years of DH trying to cajole, convince, and entice her to spend more time at our house, which sometimes works, but often does not. When it was particularly hard, we suggested mediation or child therapy to which BM said "only mental people see a therapist", which put an end to that.
So over the years, we - me and DH and all the children - are used to DD coming some times, leaving when she wants, etc. It hasn't been perfect, but when she comes she's happy, so it feels like an imperfect compromise.
However, BM is now saying we owe her a backdated 5+ years of child maintenance. I'm all for mothers being well supported (I grew up in a single mum household), but I'm unsure if we/DH owe her when we have always wanted DD here 50% of the time like the other children?
I was wondering whether we revisit the mediation/therapy route to revive the 50:50 custory agreement? Or if there is something else we can do?
Thank you in advance for any help or advice :)
