If he allows you, this is sufficient.

my husband works and I raise my son at home.I spend from our bank it as needed for us and my husband said I dont need his permission every time i buy daily things. (Unless its a huge purchase) But I read that I need his permission and also his permission to donate. He laughed when i called him one time to ask if i can donate to someone. Do i really need to ask him always if he allows me generally?
