WWYD? My DSD is 20 and I have been in her life since she was 3. DH and her mum separated when she was a baby. They had bought a flat together and he signed over his share to his ex. It was in an up and coming bit of central london, ex stayed there 10 more years and did well out of it when she sold. Ex will inherit quite a bit from her own parents at some stage, which will presumably come to DSD (only child) in due course.
DH and I have two kids (8 and 10) and we get on well with DSD, and it is amicable with her mum too. No dramas about money, contact etc. We had previously written a will which guaranteed maintenance payments to DSD until she turned 18 but all else to me / in trust for our kids if we both died. We need to update it now. My feeling is that we should have mirror wills (I/he gets everything if he/I die) but that the 'if we both die' version should still just be for our own DC. He wants a provision for his DSD in both versions.
What have others done? How much should be given to DSD as a 'special provision?'
(I have seen a couple of other similar topics recently but starting a new one as my situation is different so don't want to takeover on another thread!)
