How do I get husbands name off financial accts. He has alzheimers.

If your husband has Alzheimer's, he may or may not have legal capacity to enter into a marital property agreement giving up his interest in the accounts.  He also may or may not have legal capacity to deal with them.  See a local elder lawyer about this and about the possibility of becoming community administrator or guardian/conservator with the sole right to manage those accounts.  Use the Find a Lawyer function on the website of the National Academy of Elder Law Attorneys (www.naela.org)
