How to deal with miserly, multi-millionaire sister?
I have heard that millionaires protect their assets by being extremely business savvy and being very frugal. But this is a new low. Dont pay her, have her take you to small claims court and when the judge hears what she did to you in your situation he will rule in your favor. Millionaire or not, your sister is wrong and you don’t owe her a dime. Stay well and move forward.
