Zakaat on a joint account
Q: My wife is a housewife and does not earn an income. I provide her with an allowance as well as contribute into a savings/investment account for her.
Questions:
1. Is she liable for zakaat on the money in her investment account (which I contribute towards) or am I?
2. If we have a joint savings account (in both our names), who is responsible for the zakaat in this account?
3. Since we are married in-community-of-property, would she be responsible to pay zakaat on any investments that are in my name?
