did I have to get attorney if i am the only heir to be able to but my moms home and automobile in my name

I agree with the attorney who answered previously if your question meant to say "but the house and car are in my name." It occurred to me that might be a typo and your question was about putting the house and car into your name. If your mother died without a will and you are the only air, to get title to her assets you will have to open an estate for her in the probate court. If there are no significant creditors and truly no other errors, it is possible you could finish that process with no attorney, however I don't think any attorney who goes to probate court would advise you to do that. Depending on the value of the house it's probably a pretty simple probate, but "simple" means something a little different when you're talking about going to court.
