A: While it more of a tradition than a requirement, many dads appreciate the gesture of being asked for their daughter's hand in marriage. However, since you can marry whomever you like, regardless of your father's wishes, nowadays most men ask for a father's blessing, not permission. If you think your dad may be upset if your future groom doesn't consult him ahead of time, tell your boyfriend to make sure to talk to him before proposing.
If you're not sure what your dad would like and don't want to ask him, talk to your mom. She'll be able to tell you if your father expects to be asked.
