Married couple, unemployment benefits/job

If a household in Germany does not have enough money to survive, the Jobcenter pays the survival minimum (called HartzIV).
Once the household earns enough to survive on its own means (no matter where it is coming from), the payments are stopped.
If the household earn something, but not enough to survive, the paymnts will be reduced in order to only cover the shortfall to the survival minimum.

Since I assume your friend earns enough for him and his wife to live on (and they live in the same household), the Jobcenter will not pay any more. Why should they if the couple now has enough?

Thank u so much for reply.these things not easy to understand.they have some debet and as well non eu have to care his parents who they not live in Germany he have to send money to them for survive.

I guess there is no minimum amount that show if  he earn  for example after tax 1500 euro then job center not pay if he earn less then job center help them with little bit money .

At all much thank u with this form people get lot of help

The rules and calculations are quite complicated, but in general the Jobcenter pays the shortfall to a minimum survival rate (which is around EUR800/month per person).
Payments to relatives who aren't even in Germany are definitely not considered - and the Jobcenter also does not do any debt relief. (Why should the German state pay for such things???) But as long as the couple is on HartzIV, the debtors and the relatives cannot enforce payments, so they should just stop paying.

Thank you so much for ur precious information.
