This is a good subject--what legal things are we talking about? The biggie is a will and everyone should have one. If you do already, just read it and make sure it is all up to date. if not, the lawyer who originally drew it up can correct it for less money than a new one. you can also look on line for wills that you can do your self, but I would not suggest that if you think there would be any possible arguing over his estate. the power of attorney you will need very much if he can not speak or sign in the future. I found one on line and downloaded it, then had it notarized. never had a problem with it and have opened and closed bank accounts, sold property, paid taxes. A living will or healthcare proxy is important, check with a local hospital for those forms. The Social security department does not accept a regular power of attorney or healthcare proxy, they have their own form. I never got one of those but really need one. If you have to speak to them on your husband's behalf they must have one of theirs. your husband would have to request it. from them.
Also, most lawyers will give you a free consultation. you can vist several, and ask lots of questions. they often have a flat rate for will preparation because most people are fairly simple. Be sure and get one for yourself at the same time!
So, that is all I can think of or use...but I bet there are alot of people here with good Ideas. I am curious to see what others add!
