How do you find is someone has a will?

You look for it. Nobody's going to contact you if they don't know where it is either. Someone needs to find it.

Either you KNOW where the will is, or you don't. Until and unless someone files the will in probate court, there is NO WAY to find out if they left a will other than FINDING it yourself.

You 'think' he left a will naming you or your sister as executor. I KNOW that if that were true, he would have told you, unless he was an IDIOT.

How well do you know the brothers? Ask them about the will.

If someone writes a Will then before they name an executor/executrix they would normally ask that person if they will do the job, certainly they would tell the person after and tell them where to find the Will...so it is unlikely this 'friend' made a Will

Normally one is asked in advance if they are willing to serve as an executor of a will and where to find a copy of the will. If none of that has taken place you are not likely to be the executor.

Situations like this is why a person making a will should tell the executor where it is. If you trust the person to the executor of your estate, then you should trust them enough to tell them while you're living.

Best bet he had a personal lawyer who drafted a Will and has a copy, Now if he had a Will which cut out the brothers and they find that Will I wouldn't bet on them telling you about the Will but take a chance and claim they never found one

Wait and see if you're contacted.

It isn't as if they let strangers ransack his house. Unless he has filed a will with some lawyer, which isn't likely, they'll inform his next of kin.

Someone should go through his private papers to find if there is a will, in his house is the best place to start, the two brothers should do it together, then find out if he had a lawyer,ask local law firms, every one should make a will, and tell relatives where it is!

Only when a will goes through Probate Court does it become a public record. There is not much you can do to find out if one exists. Search his personal records. Check his records to see if he had a personal attorney.
