My dad died without a will and he has two property left with no will. He has two children, and they where informed to get a probate lawyer,need info.

I'm not sure what your question is. If your father was the sole owner of assets, and those assets were not subject to any beneficiary designation, and he had no Will, then someone will need to open his probate estate and be appointed as Administrator (called Personal Representative in some states). If his principal residence was in Georgia, the heirs (children, any surviving spouse, and possible grandchildren if any predeceased children existed) can select a person to serve as Administrator, and that person should file a Petition for Letters of Administration. If all heirs agree, the Administrator can also be given the right to serve without posting a bond or filing inventories and reports, and can be given a "grant of certain powers," which allows the Administrator to work as freely and easily as possible with very little ongoing court interaction. This can save time and filing fees. But if no Administrator is appointed, the estate cannot be properly administered, and the property titles won't be nearly as clear as desirable. There are a number of steps which will need to be completed to ensure that the estate has been administered properly, but it is very important to take them all in order to ensure that no problems with the property titles or other assets will result. The person who will serve as Administrator will need to use an experienced probate attorney to help.
