How do you apply and what do you need

Depends on where you are living,country,state, etc,for someone to answer you may have to give a little more information.

I tired to Google some information for you,but I cannot find any revelant information on widows pensions in your area.

Other people will look at your post and hopefully be more helpful then me.

What you could do is try to Google, widows pensions Ohio,and see what comes up.

A citizens advice office would be able to point you in the right direction also,but as I said above,someone will check out your post,and hopefully be able to help.

When you say widow's pension are you asking about social security spouse's benefits or are you asking about a private pension plan? Please explain a little more so that we can better advise you.
