My Dad's Will left everything to my Mom. Does that mean my Mom gets everything that my grandma left for my Dad?

Now does that mean my mom now gets everything that my Grandma left for my Dad? - yes.

Is she "next of kin"? - yes, assuming your father and mother are still married and not divorced.

How long after death does the things left in the will actually belong to the person it was left to? - title would pass to the beneficiary with immediate effect; but n.b. the administrative side of things will lag behind. Paperwork takes its sweet time.

I am sorry for your loss. What a double tragedy.
I hope that you are on good terms with your mom, because "Yes, she is next of kin." What state are you in?

You will probably sell Grandma's house right? And you need a lawyer to clear the title for the sale. So go see a lawyer who will take 1-2% of the sale for the closing. You can pay him from the sale of the house. For a few hundred more, he can make up a new Will for your mom.

If you truly are indigent you would probably qualify for legal aide. Google "legal aid" for San Jose, California or the county in which it's located, or find and call a San Jose Bar Association or the county bar association to find out how to reach legal aide.

Legal aide will provide limited advice on various issues.

I know its soon to be worrying about this but time & expenses are not on our side. My dad does have a will & he left everything to my mom. We dont have $ for a lawyer either. I didnt even know where to go for advice except for here.
(oh Im in San Jose, Cali if that infos needed)

A lot depends on the verbiage used in a Will. As others have mentioned, the lawyer who drew up the Wills can sort it all out.

That is why it is so important to update one's Will every few years or anytime there are changes within the family. My parents each have a Will and the way it is written is if one passes on, everything goes to the living spouse, except for a certain monetary item that will go to me.

I'm so sorry about the loss of your grandma and your dad. What a blow to the family.

Your mom will need a lawyer to sort all of that out.

If your father died without a will or trust, he is considered to have died "intestate", in which case assets are inherited according to various state laws. This is something an attorney would should determine as the intestate laws aren't always easy to follow.

I too am sorry for your loss, but suggest that you give you and your mother time to grieve and address the issue of inheritance after the funerals, unless there is a concern as to how to pay for the funerals.

So sorry for your two losses. You certainly seem in a hurry to get to the inheritance. Goodness, your Dad just died last night. You need to step back and allow the rest of the family time to grieve.

There is no big rush and no real time limit. Your Mom needs to contact a lawyer (when she is ready) possibly whoever did Grandma's will or your Dad's. Everything goes to your Mom as the spouse and next of kin.
