My mother left my older half sister in charge of her money. Then my sister died of cancer. But she left her husband in charge of her money. Knowing my mother has to children me and my sister. I want to know is this legal.
Your use of pronouns is confusing. Whose money did your sister leave her husband in charge of? Your sister's money? Your mother's money? They are separate concepts. And how did your mother leave your sister in charge? Was she appointed legal guardian through a guardianship proceeding? Was there a Power of Attorney or did she just say "Here, manage my money"? If there was a Power of Attorney or legal guardianship, she has to manage the money for the benefit of your mother, not her benefit, meaning your mother's money isn't hers and she can't just leave your mother's money to someone else. Also, how old are you and your sister? Are you minors? Because that would create another issue separate from the issue of guardianship. You should arrange a consultation with a local attorney to sort this out and find out what your rights really are.

This sounds like a probate issue - you should contact a probate attorney to see if you have any cause of action.
