u have my sympathy, i too have a bullying ex who has threatened to report me for fraud, when he left us in a financial mess, and holds this over my head, and basically , now gets away with anything he chooses.
Hmmm,
If you change your circumstances now, its prob wise.
Is there really any proof, of how long your ds has been living with the ex?
Does the amount ex is supposed to pay you enuff to bother with. I know its their duty etc, but i dont think you are gonna see that money from the past, but the money now, is it a fair amount, cos if not its not even worth bothering cos they will take it out yuor inc support inyhow, if you're on it, so basically these men get away with this, cos its not worth our time.
oh yes and its also not worth us going to prison for.
My solicitor sadi that she had rarely come across a man who would seriously report an ex for fraud, and that even if he did, the courts would seriously look at the bigger picture, and the stress, and the dificulties you are in.
