I recently got custody of my 13 year old grandson [View all]

The papers clearly state that we have shared custody with my stepson with my wife and I having residential custody as we are able to provide a safe and stable home place as well as the child stating in court that he wishes to stay with us.

Recently my stepson appliied for food stamps and Medicare portraying that the child resided with him. This was the main lie among many others.

He lives with his wife's parents and claims to be separated from his wife to draw more benefits on the 4 kids he does live with.

I have a strong desire to set the record straight at least as far as the child I have custody of is concerned. This will no doubt cause upheaval in my marriage. But damn it, you do what is right because it is right. Any ideas? The fraudsters he is in bed with are stealing 40k a year and likely much more.
He even wants us to give the boys new school his address rather than ours and it is in a different district and town.
I was a prison guard for quite awhile and have little sympathy for thieves, kin or not.

I guess I am hoping that someone has been in a similar situation and can give me advice. Every fiber of my being tells me to speak up and not be complicit in this bullshit.

Thanks for letting me vent.
