Can my parents disinherit me from their will?

Yes, your parents can legally disinherit you from their wills. Under Georgia law, a person has the right to dispose of their property and assets as they see fit upon death, even to the exclusion of their children or other heirs.  The appropriate time to challenge a will in Georgia is after the death of your parent (in the context of your question) and at the time the will is offered for probate in the probate court of the county of your parent’s residence at the time of death.  You might have grounds to challenge the will(s) at that time if, for instance, it can be shown that they excluded you from the will because of certain legal factors, such as undue influence or mistake of fact.   

That is really a question for an estate planning attorney, however, my understanding is that yes, parents can disinherit their children, but it must be done properly in the will, and children may petition the court for what’s called a year’s support.  Please consult with an estate planning attorney for more information.
