Does a Spelling Error Make a Power of Attorney Invalid?

No, it shouldn't. That’s what’s sometimes called a "scrivener’s error." The person preparing the document made a minor mistake, but that does not change your father-in-law's intent to name your wife as his agent under the durable power of attorney. It’s not as if he has another daughter named Ann. That's the legal answer. As a practical matter, if your father-in-law is still competent it might make sense to update and correct the durable power of attorney. You never know what some officious bank manager might object to.
