Legal Question in Wills and Trusts in Pennsylvania

I do not understand your question. If there is no will, someone has to be the personal representative (called an administrator). Is there a court file? If so, its a public record. I assume this estate is in Pennsylvania. Go look at it. Your brother has to identify the heirs. Your brother also has to file an "inventory" with the court listing the property owned by the decedent. Has this been done or is it time to do this yet?

If something does not look right, I suggest you get a probate litigation attorney. If your brother really is concealing assets then he can be removed. However, you need to have more evidence than just your belief or a feeling.

I do not know what other work you expect an attorney to do. If you really believe that your brother is hiding assets, then the attorney can hire a private investigator to uncover such evidence. This will be expensive. You have to consider the level of assets that are at stake and the likelihood that an investigator will find evidence of wrongdoing.
