DP and I both work full time, but not flush by any stretch of the imagination.
Mil is an addict and claims benefits including child benefit, tax credits etc for DPs younger sister, who lives with and is financially supported by another family member, which is obviously not declared.
We help out quite a lot practically, but for while now this family member has been hinting more and more that we should start paying for the upkeep of DPs sister.
We would never see her go without, but we both agree that the general attitude of the wider family is enabling mil to stay in the ditch she is in.
AIBU to refuse to make any financial commitment towards this situation until the benefit fraud stops?
