I'm not even sure this is the right place for my thread, but I'm after some input.
Separated/divorced 11 years. One 14yo DS plus three adult DCs. My ex and I initially had 50/50 but this has shifted over the years where all of our children eventually spent more time with me than their dad, or moved in with me as adults.
I'm happily remarried, I instigated the split, and I have no interest in my ex in any way, other than frustrations over what a low-effort, bare minimum parent he is.
Our only remaining 'child' has, for the past few years, split his time 70/30 with the majority spent with me. Our agreement has remained in writing as 50/50, with him having main custody (this was agreed reluctantly by me, purely because he is a deadbeat was constantly unemployed and I was the breadwinner). He received benefits on this basis which enabled him to have a home that had space for all of our DCs.
I won't be entitled to any financial support from him or the benefits system if I successfully have our agreement changed, but my ex would lose money. I think I'm just tired of his glory hunting as a single dad whilst I do the lion's share of the parenting (emotional as well as practical), and have the extra expense (which I do not grudge my son in any way!) whilst he claims all of the associated benefits. He is the primary contact for school etc and I'm sick of relying on him to pass on information etc - I think he often drip feeds it as some kind of bizarre power move.
Would it be ridiculous to involve lawyers again so far down the line? I suspect that any successful move on my part would force a house move on his, however this would eventually happen when the youngest DC becomes an adult.
